Dental Fillings (Restorations)
A filling is a material that your dentist uses to fill a cavity after the dentist removes any tooth decay. To fill a tooth, your dentist will numb the area, drill out the decay, and put in a filling. There are many types of fillings.
Types of fillings
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's the fastest and least costly choice. Amalgam is a mixture of mercury, silver, and tin or other metals.
- Composite resins are tooth-colored fillings. Composite resin is easier than gold for a dentist to work with. And it usually costs less than gold.
- Ionomers are tooth-colored materials that dentists often use for small cavities or cavities between teeth. Some ionomers release small amounts of fluoride. This may help you if you often get 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-colored fillings. They require special equipment and may require dental lab support. You may need several appointments.
What To Expect
After your dentist has filled the cavity, your lips and gums may stay 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.
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. This problem can usually be treated.
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. It may cause pain and then an abscess. This may 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.
Risks
Problems from having a cavity filled aren't common. If they occur, they are usually minor and get better with time. The most common problems are:
- Tooth sensitivity to heat, cold, or brushing.
- Soreness in the area.
- Bite problems caused by the filling being too high. If your bite feels too high, let your dentist know right away so they can fix this problem.
If you have certain heart problems, your dentist may prescribe antibiotics before a dental procedure. Some procedures can cause bacteria in the mouth to enter the bloodstream and cause infections in other parts of the body. The antibiotics lower your risk of getting an infection in your heart, called endocarditis.
