Bonding - Sometimes a chipped tooth can be easily repaired. We
apply a tooth colored acrylic resin to the tooth and blend it to match
your bite and smile.  Using this technique we can close space between
the front teeth as well.
More procedures and pictures will be displayed here soon.
Maryland Bridge - When a single tooth or more than one tooth are
either congenitally missing or have been lost, they can be replaced with
either a Maryland bridge, as shown below, or dental implants which will
be shown further down.  In this case the patient opted for the Maryland
bridge.  Its a conservative restoration that can have excellent
Crowns - These are restorations that cover a weakened or
damaged tooth.  They can be made of ceramic to match the teeth, or
can be made of gold.  Below, the patient had a "dead" tooth and
following a root canal it turned dark.  This demonstrates an all
ceramic crown.
Dental Implants- If you have a single missing tooth, or
multiple missing teeth implants are ideal for fixed, permanent
replacement.  We can apply them to increase full and partial
denture retention as well.
Filling Materials
Composite Resin-
latest materials to match your existing
teeth with very high strengths.
  Amalgam- This material has been around for many years,
but not widely used anymore.
  Ceramic Inlays/onlays- When you do not need a full
crown but a regular filling will not be strong enough.  These
can be done with cast gold also.
Mouth guards- We often recommend guards for various
reasons.  Depending on the patients habits we can
customize an appliance to protect your teeth from grinding,
clenching, and even sports injuries.
Snoring and Sleep Apnea

Snoring is no laughing matter. It is a signal that something is wrong with
your breathing during sleep. It means that the airway is not fully open and
the noise you make comes from efforts to force air through the narrowed
For many people who snore the problem has no significant medical
consequences. However, for others snoring is the first sign of a
potentially life threatening disorder called Obstructive Sleep Apnea.

What causes snoring?

During sleep, the muscles and soft tissues in the throat and mouth relax
making the breathing airway smaller. This decrease in space increases
the velocity of air flowing through the airway during a breathing cycle. As
the velocity increases in the constricted space, the soft tissues vibrate
producing the classic snoring sound.

What is Obstructive Sleep Apnea?

An apnea episode is defined as the absence of breath for 10 seconds or more.
Someone is considered to suffer from Obstructive Sleep Apnea if they stop
breathing like this for 5 or more times an hour while sleeping. In severe cases
of Obstructive Sleep Apnea a patient can suffer from 30 or more apnea events
per hour.
When these interruptions of breathing occur, oxygen in the blood drops
causing your blood pressure to rise and your heart to work harder. It also
disrupts normal sleep cycles causing you to suffer from excessive daytime
sleepiness (EDS). That is why some people are chronically tired or sleepy even
after "sleeping" for 7 to 8 hours. Over time, these episodes of apnea can be
associated with high blood pressure and other cardiovascular diseases, risk for
heart attack, risk for stroke, pulmonary hypertension, migraine headaches,
hyperactivity in children, memory problems, depression and anxiety, job
impairment, and motor vehicle crashes. Bottom line is that Obstructive Sleep
Apnea is an extremely serious sleep disorder that can decrease quality of life
and significantly decrease life expectancy.

How do you know if you are suffering from Obstructive Sleep Apnea?

The only way to know if you have OSA is to be seen by a sleep specialist and
be tested. These tests can be performed at a sleep center or at your home and
will provide the necessary information to make a diagnosis.

The following screening questions are a good start to determine if you need to
be evaluated by a sleep specialist:

- Do you snore?
- Do you have high blood pressure?
- Has anyone reported that you choke or gasp for air while sleeping?
- What is your neck size? (>17 for men or >15 for women is a concern)
- Do you wake refreshed?
- Are you excessively tired during the day?

Dr. Congalton is not a sleep specialist and therefore cannot make a medical
diagnosis of OSA. He does however recommend you get in contact with the
proper medical professionals.  We can fabricate an oral appliance to wear at
night, in place of a CPAP device. If you do not have sleep apnea, and only a
snore issue, this appliance will help you as well.  Should you have any
questions please contact Dr. Congalton.  (802) 877-3534
Complete Dentures/ Partial Dentures
If you have no teeth, a complete denture will replace all of your teeth in the
affected arch.  If you have had a bad past experience with dentures, there
are things we can do to improve retention and fit.  If you have some teeth
remaining, and they are reasonably healthy we can fabricate a framework to
attach to those teeth.  On that framework we will add any teeth you are
missing.  There are many things to consider, its best to contact the office
and schedule a consultation with Dr. Congalton.  He can explain the process
and steps involved to restore your smile and dental health.
Teeth Whitening - Using the newest in bleaching techniques
we can whiten teeth with almost any type of stain or discoloration.
