About
Preventative Dentistry
Preventative dentistry is the practice of good oral hygiene
to prevent tooth decay and gum disease and includes home care, nutrition, and
regular dental checkups and cleanings. You dentist can help you and family
members with recommendations to obtain and properly use a variety of home
hygiene support devices and products that strengthen teeth, keep your teeth and
gums clean and healthy, and help prevent cavities and gum disease. Your dentist
can also recommend and perform in-office treatments like applying tooth sealants
and fluoride treatments to help prevent cavities.
A good tooth brush recommended by your dentist and a good
tooth paste, dental floss, and a dental rinse are all part of a good oral
hygiene regimen. Brushing frequently, especially after meals is a must. Rinsing
your mouth with water after drinking acid drinks or eating also helps to
prevent the growth of bacteria called plaque that can damage your teeth and
make your gums bleed easily. Limiting sugary foods and acid drinks also helps.
Sugar feeds bad bacteria that attaches to your teeth. These bacterial colonies,
called plaque will multiply to the point where they become too thick for the
layer closest to the tooth surface to breath. To survive, these bacteria go into
a state of anaerobic respiration, which means they live without using oxygen. Anaerobic
respiration unfortunately produces acid and it is this acid production that
eats away at the enamel of your teeth and causes cavities. The better care you
use to prevent this process, the better the health of your teeth and gums are
likely to be.
Preventative dentistry doesn’t just stop with preventing
cavities; it is also an important part of an oral health regimen for patients
who have had previous dental work done. Fillings last a long time but not a
life time. They can expand and contract with hot and cold foods and may need to
be replaced to help protect your teeth throughout your life. As you get older,
proper care of the gums is even more important. Reduction of plaque and proper
oral hygiene for bridges or other dental procedures like implants will reduce
the chances of a receding gum line, which could lead to gum disease, loose
teeth, or other dental problems.
Frequent dental checkups, usually every six months, can
greatly help in the prevention of dental problems and with the aid of a dental hygienist,
you can have your teeth professionally cleaned and cared for.
Benefits of White Fillings
White fillings are also called composite fillings. They more
closely match the color of your teeth and may even appear to be invisible.
Composite fillings are not generally considered to be as strong as amalgam and
gold fillings but do have an advantage over the weakening affect an amalgam
filling can have to a tooth. This is because composite fillings are bonded to
the tooth. Teeth restored with white fillings are also less sensitive to hot
and cold than teeth restored with amalgam or gold. Another advantage is that
generally, less of the tooth needs to be removed, especially with small
cavities.
White fillings are more expensive than amalgam and a special
bonding technique is required to make the composites adhere to the tooth
properly. The tooth must be isolated and kept free from contact with saliva
throughout the bonding procedure. This makes adding composite fillings to back
teeth, where salvia is more apt to accumulate, a bit more difficult.
White fillings are usually recommended for front teeth,
where the wear from chewing is less and the cosmetic appearance may be more
important to the patient.
People who use alcohol should inform their dentists.
Excessive use of alcohol can seriously weaken the bond in the composite
fillings and cause them to prematurely fail over time.
About
Crowns
Metal crowns are preferred for strength but acrylic resins
and porcelain crowns will have more of a natural appearance. In general,
acrylic and porcelain crowns are preferred for front teeth while gold or other
metal amalgams are recommended for back teeth where increased strength and
durability are required.
A crown requires an impression (mold) of the area to
properly fit the crown in place and to maintain a proper bite between the upper
and lower teeth. A small amount of enamel will be removed from the tooth to
provide a surface for the crown. A wax or plaster impression will then be made
and sent to a dental laboratory. A temporary crown will then be cemented on
your tooth until the crown is ready. On your next visit, the temporary crown
will be removed and your new crown will be cemented in place and adjusted to
achieve a proper bite. The crown may require a finishing coat to seal it and
improve its natural appearance. Such coatings are typically acrylic polymers.
The polymer can be painted on as a thin film, which hardens to a durable
finish.
If a crown ever needs to be removed due to a traumatic
injury to the tooth, a cavity, infection, etc. a special removal tool can be
applied that places a precision vertical channel in the surface of the crown
and simply threads the surface until the bond is broken. The crown can then be easily removed without force.
Benefits of Fixed
Bridges
Fill space of missing teeth.
Maintain facial shape.
Prevent remaining teeth from drifting out of position.
Restore chewing ability.
Replace a removable partial denture.
A dental bridge may be recommended to replace missing teeth.
Unlike a partial denture, a bridge is fixed, meaning it is not removable.
Bridge materials include gold, porcelain, or porcelain fused to metal. Although
porcelain bridges may look the most natural, they will only be recommended in
areas where there is sufficient reason to believe they can function without
undue stress, which could cause failure. Porcelain fused to metal will add some
strength while maintaining a good cosmetic appearance. Gold is more durable but
is less cosmetically aesthetic.
A bridge is anchored to the adjacent teeth to hold it in
place. To accomplish this, a mold of the patient's mouth is required to
accurately measure this space. First, the two anchoring teeth are prepared by
removing a portion of enamel to allow for a crown. Next, a highly accurate
impression (mold) is made and sent to a dental laboratory, unless the office
has a lab on site. If not, a temporary bridge will be fabricated to wear until
the new bridge is completed. At the second visit, you permanent bridge will be
checked, adjusted, and cemented into place. In some cases, your dentist may
want to temporarily cement the bridge to allow your gums and teeth to get used
to the bridge and permanently cement the bridge in place at a later date. Your
dentist will also discuss the care of your new bridge, including proper
brushing, flossing and checkups to add longer life to your new bridge.
Benefits of Veneers
Fix crooked or misshapen teeth.
Be rid of severely discolored or stained teeth.
Fix teeth that are too small or too large.
Get rid of unwanted or uneven spaces.
Fix worn or chipped teeth.
Create a uniform, white, and beautiful smile.
A dental veneer consists of a thin layer of composite
material or porcelain, which is placed over a tooth surface. A veneer is used
to either improve the way a tooth looks or to protect a damaged tooth surface.
A composite veneer may be added directly in the mouth or fabricated in a dental
lab and then bonded to the tooth, usually with resin based cement. A porcelain
veneer may only be fabricated in a lab and then bonded to the tooth.
Due to improved bonding agents, veneers have longer use
expectancy than they did when they were first made available in the 1980's.
Today veneers typically last between 10 to 15 years.
Veneers may be recommended to produce a slight straightening
affect or help equal spacing and size differences between teeth. A dentist may
also recommend a veneer to restore a single tooth that may have been fractured
or discolored. For teeth that have been worn away at the edges, veneers offer a
way to close the spaces and lengthen the teeth that have been shortened by
wear.
Of the choices of porcelain or composite veneers, the
porcelain are generally considered the best looking but are not as durable as
the composite veneers. Porcelain veneers are also more expensive. Alternatives
to veneers are crowns and resin bondings.
Getting veneers require two visits and there is generally
little or no anesthesia or drilling required. The teeth are prepared by lightly
buffing and shaping the surface to hold the thickness of the veneer. A mold or
impression of the mouth is made and a shade (color) chosen by you and the
dentist is needed for the lab to make the veneers. On the second visit a
special fluid is applied to your teeth to achieve a durable bond. Bonding
cement is then applied between the tooth and veneer. A light beam is then
applied to the veneer to harden the bond.
Benefits of Tooth Bonding
Tooth bonding is a cosmetic dentistry technique to help
improve your smile. The process involves using a composite mixture of silicon
or quarts bound with resin. This composite is blended to produce different
shades and toughness to match your existing teeth and provide adequate
strength. Tooth bonding can be used to close gaps between your teeth, fill
cavities, or eliminate spots, chips, or areas of tooth discoloration. Bonding
can even be used to repair a chipped front tooth.
Your dentist can perform the bonding process in the office
without the use of a lab, as is the case when veneers are desired. Bonding is a
simple process of lightly roughing the area, which usually does not require
anesthesia, applying the bonding resin, applying the composite, and sculpting
it to fit. A high intensity light may be used to help dry the composite,
especially if it is being used as a white filling. The composite is then
polished and the procedure is complete.
Tooth bonding generally lasts several years without any
noted discoloration. It helps to avoid foods that tend to stain teeth and it is
usually recommended to brush with a mild toothpaste if extensive bonding was
done. Using a harsh polishing toothpaste will often dull the surface of the
composite material over time. The good news is that touchup work is fairly easy
to do if dulling or discoloration becomes a problem in time.
Benefits of Teeth Whitening
Get rid of stains on teeth.
Remove discoloration from excessive use of fluoridation.
Tooth whitening usually requires two visits. The first visit
involves making impressions (molds) of your upper and lower teeth to fabricate
custom, clear plastic, trays. At your second visit these trays will be fitted
in your mouth and adjusted, if necessary. You will need to fill these trays
with specially formulated whitening solution and wear them as directed by your
dentist, usually either twice a day for 30 minutes or overnight for a couple of
weeks, depending on the degree of whitening desired. This whitening process
will usually create increased tooth sensitivity during the whitening process
that should subside shortly after the whitening process is finished.
About Gold Fillings
Gold fillings may be recommended to replace worn amalgam
fillings. A cast gold filling won't corrode and for small cavities, gold foil
is used. Another advantage with gold is that it is a somewhat softer metal and
has a tendency to have a longer life. Gold is considered a low-reactive metal
and because of this, it also provides a much stronger base for bridges or
crowns. Although gold wears better it does conduct heat and cold more; so,
people with extreme problems with temperature sensitivity may not respond to
gold dental work.
About Nitrous Oxide
Nitrous oxide, also called laughing gas, is an odorless and
colorless gas that removes the sensation of discomfort during certain dental
procedures such as filling a cavity. Interestingly enough, one of the pioneers
in the field of Nitrous Oxide development, Humphrey Davy (1778-1829), described the effects of nitrous
oxide on himself following self-administration for a toothache and gum
infection. Davy wrote:
"On the day when the inflammation was the most
troublesome, I breathed three large doses of nitrous oxide. The pain always
diminished after the first four or five inspirations; the thrilling came on as
usual, and uneasiness was for a few minutes swallowed up in pleasure."
For people who are overly anxious about dental procedures,
nitrous oxide may be a recommended option to help put you at ease as well as
numb any discomfort associated with your condition or your dental procedure.
Although unlikely to make you 'laugh' during the administration of the gas, it
can create a sedative and anti-anxiety affect, which can help promote relaxation
and a feeling of general well-being.
Nitrous oxide has very few side effects and wears off
quickly when the procedure is over. This makes it suitable for patients of all
ages. The gas is easily administered through a tube attached to a small rubber
face mask. The flow of the gas will be adjusted to your individual needs.
Nitrous oxide is not meant to put you to sleep, as higher doses needed to
accomplish sleep would lower the oxygen in your bloodstream too much. Rather,
the gas is used to produce a "conscious sedation." Think of it as
being in a somewhat aware but you really don't care. A local anesthetic to numb
your tooth may be applied after the gas takes affect because nitrous oxide is
not classed as an actual pain reliever.
About Dental Extractions
Tooth extraction is generally a procedure of last resort
when a tooth becomes too unsound to repair or presents a structural problem
such as an impacted wisdom tooth. Extraction involves either the use of
multiple local anesthetics to numb the area as thoroughly as possible or your
dentist may recommend in the use of general anesthesia, which allows you to
sleep through the procedure.
Depending on your sensitivity to dental procedures, nitrous
oxide gas or other forms of IV medication can be used to help reduce anxiety. I
general, excessive infection and inflammation in a tooth about to be extracted
will make it more difficult for a local anesthetic to perform well and being
asleep through the procedure may be recommended for that reason. Without the
interference of excess inflammation, the local anesthetics used today can make
the extraction process itself, painless.
A tooth is satisfactory structural condition can usually be
extracted by loosing the bond with the gum with a quick back and forth motion
and them simply removing the tooth. If your dentist feels your tooth will not
be able to remain intact by this extraction method, your tooth can be removed
in sections. Dental instruments are used to section the tooth into two or more
pieces and then each sectioned piece can be removed.
Bleeding after the procedure is usually mild and responds
well to the use of sterile gauze held with compression against the removal
area. Your dentist will explain the proper care of the post-operative area
including foods to avoid, proper changing of the gauze material, how often to
rinse and what to rinse with, and instructions on food preparation to allow the
area to recover. Other recommendations may include the use of moist heat and
cold compresses and things to avoid like drinking through a straw (sucking
action discourages proper clotting.)
Bridges, dental implants, partial or full dental plates
(dentures) are often recommended to replace the tooth or teeth that were
removed. Your dentist will discuss the proper healing time needed to begin
these restorative procedures. If wisdom teeth were removed, there is no need
for restorative dentistry.
About Dental Implants
Dental implants provide an alternative to bridges, partial
plates, and dentures. To help determine if you are a candidate for implants,
your dentist will take a panoramic x-ray of your mouth to see all the teeth on
one film. This helps your dentist to determine if the space between the roots
of your teeth and sinuses above them are sufficient enough to support the posts
required to support the implant. Implants can also be recommended and used to
support bridges where two implants are made and a bridge is placed between them
to fill the gap of several missing teeth.
If your bone structure is determined to be suitable for
implants, the actual procedure can usually be done while under general
anesthesia in under an hour. After the implant is set in place, a period of
integration with your surrounding bone is required before the procedure is
completed. This integration process is where the dental implant root becomes
anchored to the bone of the jaw. The time it takes for this bone integration
varies. Usually between three to six months is required for full integration
and healing. The process should be carefully monitored because if
osseointegration (the formation of new bone) does not occur, the implant will
fail; however, if successful, the integration with your own bone tissue is the
reason why these 'osseointegrated implants' are the most commonly used and
successful type of dental implants available. After complete healing is
obtained, your dentist will finish the procedure by placing a crown on the
implant or if an implant was set in place to accept a bridge, that work can
then be started.
A dental implant is commonly composed of a titanium screw
and a crown. A small pilot hole is drilled at into the jaw in order to guide
the titanium screw that holds a dental implant in place. After the pilot hole
has been drilled, the hole is slowly widened to allow for placement of the
implant screw. Following this placement, a protective cover screw is placed on
top to allow the implant site to heal and the dental implant to anchor (begin
osseointegration).
After several months, the protective cover is removed and a
temporary crown is placed on top of the dental implant. The temporary crown
serves as a template around which the gum grows and shapes itself in a natural
way. The process is completed when the temporary crown is replaced with a
permanent crown.
There is no guarantee that an implant procedure will be
successful, but studies have shown a five-year success rate of 95% for lower
jaw implants and 90% for upper jaw implants. The success rate for upper jaw
implants is slightly lower because the upper jaw (especially the posterior
section) is less dense than the lower jaw, making successful implantation and
osseointegration potentially more difficult to achieve. Lower posterior
implantation has the highest success rate for all dental implants.
Dental implants may fail for a number of reasons. The cause
is often related to a failure in the osseointegration process. For example, if
the implant is placed in a poor position, osseointegration may not take place.
Dental implants may break or become infected (like natural teeth) and crowns
may become loose.
If you are a smoker who is considering a dental implant,
your dentist will likely advise you to give up smoking before undergoing the
process because smokers face a higher risk of implant failure.
On the plus side, dental implants are not susceptible to the
formation of cavities; still, poor oral hygiene can lead to the development of
peri-implantitis around dental implants. This disease is tantamount to the
development of periodontitis (severe gum disease) around a natural tooth.
About
Root Canals
A root canal may be recommended by your dentist if the
cavity is too deep to fill with a normal dental filling. A root canal may also
be recommended to repair a deep lost filling, a crown that has failed, or other
tooth damage or decay where a standard filling would not be indicated. The
reason a standard filling cannot be used is because the damage to the tooth
results in bacteria infiltrating into the pulp of the tooth resulting in an
infection. Generally swelling is present in the gum above the tooth when such
infection occurs.
With an oral examination and x-ray of the tooth, your
dentist can determine if your tooth has become infected and would benefit from
a root canal procedure.
A root canal is an eudemonic procedure that removes the
infected tissue and treats the infected area to prevent further bacterial
growth. To accomplish this, the dentist applies an oral mask to isolate the
tooth and keep the area clean. The oral anesthesia used today is very effective
in numbing the area and the discomfort formerly associate with a root canal has
be significantly reduced. The drilling takes longer, because the pulp cavity
must be reached, but other than the extra time required, the drilling procedure
is much like that used for a standard filling. In some cases, if the infection
is not too extensive, a single visit is all that is needed to perform a root
canal. More extensive cases of infection require a second visit.
Once the drilling is completed and the tooth is
treated,
your dentist will determine what support the tooth requires to hold the
crown. (An exception is when a crown already exists and can be
drilled through and repaired.) If your tooth needs support to hold the
crown,
your dentist will cement a temporary crown in place to protect your
tooth and
schedule another visit. Usually, a titanium post can be inserted into
the tooth
to strengthen it in preparation for the crown on the next visit. Once
your new
crown is cemented in place and adjusted to fit your bite properly, the
procedure is finished.
You may experience some residual discomfort until the
swelling from the infection is fully reduced. There may also be some residual
sensitivity from the drilling. Your dentist will usually prescribe some pain
killers, which can be taken if needed to relieve the discomfort. In most case
any discomfort remaining after an infected tooth has been successfully treated
with a root canal procedure only lasts for a short period of time. Follow your
dentist’s instructions on use of all pain medication and other recommendations
to reduce discomfort and to take proper care for your root canal.
About
TMJ Disorders (The Jaw)
TMJ or the temperomanbibular joint can cause an extensive
variety of problems when the joint is not functioning properly such as:
Jaw pain and/or stiffness
Headaches, usually at the side of head or headaches that
feel like sinus headaches
Migraine headaches
Vague tooth pain or sensitivity which often moves around the
mouth
Tenderness in the jaw
Difficulty opening the mouth
Difficulty chewing, especially hard or chewy foods
Clicks, pops, or grinding sounds in the jaw
Ear pain
Cervical neck tension and pain
Grinding or clenching the teeth while sleeping or awake
Tooth wear or breaking/cracking teeth
A dental exam can help determine if any of these symptoms
are being caused by a problem in your jaw. The severity of the condition can
vary from mild symptoms of discomfort to debilitating pain of dysfunction. The
condition can caused from inflammation of the muscles that open the jaw, the
jaw joint itself, or a combination of both. Misalignment of the jaw or improper
growth and development of the jaw may also be cause problems with the TMJ. TMJ
problems can also be caused or aggravated by emotional conditions. Stress not
only lowers our resistance to pain but also increases muscle tension,
especially in the jaw.
Once your dentist has determined the source of the TMJ
disorder, a course of treatment can be established. Because the source of s TMJ
problem can be associated with so many factors, from stress to structural
malformation, treatments for this disorder are also varied in nature. The most
usual cause of TMJ, joint tension, is usually treated with an easy to wear
fitted mouth guard, which prevents teeth grinding and allows the jaw to rest,
especially at night. Other therapies are prescribed jaw exercises that can be
done at home and simple therapeutic measures like massage and moist heat
applied to the jaw muscle. Eating softer foods to help the jaw rest is also
usually recommended. Stress reduction may also be recommended. Less common but
more severe problems that reveal destruction within the joint itself or
structural abnormalities may require reparative surgery.
