What are dental fillings used for?

Dental fillings are most commonly used to treat cavities. However, they can also be used to repair cracks in teeth or build up a tooth that has been worn down through grinding. In some cases, a filling will successfully relieve sensitivity in the tooth caused by the damage. Other times the dentist in Orange County may combine the filling with other treatments for the best result.

What are the choices in dental fillings?

There are many different materials used for fillings, allowing the patient and dentist to work together to choose the filling that will work best in each individual situation.

• Amalgam Fillings - These common dental fillings are composed of an alloy material made up of metallic elements like silver, copper, tin and mercury. Because the fillings are a different color than the teeth, they are most frequently used in molars where the appearance will not be as important. Amalgam fillings are extremely durable and can stand up to the significant wear and tear the back teeth must endure.
• It is important to note that amalgam fillings have been declared safe by many health organizations, including the American Dental Association. Although concerns have been raised about the mercury levels in this material, the other substances in the solution serve to stabilize the mercury, making it safe for use.
• Composite Fillings - Composite fillings are a popular choice with patients because they come in a color to match the rest of the teeth. This is especially helpful if the required filling is in a visible front tooth. Composite fillings do not tend to be as strong as amalgam fillings, and will need to be replaced more frequently. These fillings might also cost a bit more and are not always covered by insurance plans.

How is a filling done?

The first step in filling a tooth is to isolate it so it remains clean and dry during the procedure. The area is drilled or a laser is used to remove debris and bacteria that have accumulated. Once the tooth is properly prepared, the filling material can be applied. It is essential that the tooth remain clean and dry throughout the procedure to ensure the bonding process is successful. The filler material is then hardened using a special light and the tooth is filed smooth and polished. The entire procedure is done right in the dentist's office in Orange County and a local anesthetic is usually used for the comfort of the patient.

How long do fillings last?

The average duration for an amalgam filling is about 12 years, although many last longer than that. Composite fillings do not generally last as long; about seven years on average.
