Treatment Overview
A filling is a material that your dentist uses to fill a
cavity after he or she removes any
tooth decay.
To fill a tooth, your dentist will:
- Numb your teeth, gums, tongue, and surrounding
skin. Your dentist will first put a substance that feels like jelly directly on
the area to start the numbing process, and then inject an
anesthetic to complete it. Many dentists will give you
nitrous oxide gas (laughing gas) to reduce your pain and help you
relax.
- Sometimes use a small sheet of rubber on a metal frame
(rubber dam) to target the decayed tooth and to stop liquid and tooth chips
from entering your mouth and throat.
- Drill out all the decay and
replace it with a filling.
Fillings can be made from many types of material. Talk to your
dentist about which type would be best for you.
- Amalgam is the easiest material for a dentist
to use. It is the fastest and least costly choice. Amalgam is a mixture of
mercury, silver, tin, or other metals.
- Composite resins are
tooth-coloured fillings. Your dentist may use them on your front teeth, where
appearance is important. Composite resin is easier than gold for a dentist to
work with and generally is less expensive than gold.
- Ionomers are
tooth-coloured materials that dentists often use for small cavities or cavities
between teeth. Some ionomers release small amounts of fluoride, which may help
you if you often have cavities.
- Gold is costly and is harder for
your dentist to work with. This makes the procedure take longer and cost
more.
- Ceramics are costly tooth-coloured fillings. They require
special equipment and may require dental lab support. You may need several
appointments.
What To Expect After Treatment
After your dentist has filled the cavity, your lips and gums may
remain numb for a few hours until the numbing medicine wears off. To avoid
injuring your mouth, be careful not to chew on your numb lip or cheek.
Why It Is Done
You need a filling when tooth decay has caused a hole (cavity) to
form on a tooth surface. If you don't get a filling, the cavity will get worse
and lead to more severe problems, such as bone loss.
How Well It Works
A filling repairs the tooth and stops tooth decay. Over a long
period of time, you may need to replace a worn-out filling.
Your filled tooth may be sensitive to heat and cold for days to
weeks after you get the filling. Talk to your dentist about toothpastes that
may help you with this discomfort. Tell your dentist if your teeth are too
sensitive after you get a filling, because you can usually treat this
problem.
Risks
There is almost no risk involved in having a cavity filled.
Some dental work can cause bacteria in the mouth to enter the
bloodstream. These bacteria can cause infections in other parts of the body.
People who have a difficult time fighting infections may need to take
antibiotics before and after dental surgery. Such
people include those who have artificial heart valves or were born with
heart defects.
What To Think About
It is important to start treatment before tooth decay becomes
worse. More severe decay may cause pain and tooth loss and may require a costly
crown, a
root canal, or tooth removal (extraction).
Some dentists now use a
laser system to remove tooth decay and prepare the
tooth for filling. Laser treatment is a relatively new choice for dental
treatment. This is a relatively new treatment and may not be available in your
area.
