How Fillings Fix Cavities

Posted in Fillings

Cavities are caused by bacteria, which can deeply affect teeth. Is the fix really as simple as plugging an empty hole in the tooth with a filling?

The Drill-and-Fill Technique

First of all, dental x-rays are essential to helping your dentist plan treatment. He or she has to know in advance how big the cavity is. Without an x-ray, your dentist may as well try placing a filling blindfolded!

Your dentist makes sure that every bit of tooth infected with the cavity bacteria is removed. The prepared hole is carefully shaped to hold a filling. Next, a liner is usually placed to give the filling a snug fit. Finally, the filling material is mixed and set in place.

Avoid Future Cavities

Just because it has a filling doesn’t mean that a tooth is not invincible to cavities! You’ll have to be even more careful about keeping that tooth clean. Bacteria love to hang out around the edges of fillings.

You can prevent getting another cavity by keeping up with brushing, flossing, and fluoride use.

When More Than a Filling is Needed

Depending on where a cavity forms on a tooth and how large it is, your dentist will recommend different treatment. If tooth decay reaches the nerve chamber of the tooth, a root canal is usually necessary. If large pieces of a tooth are lost to cavities, then a crown is best for holding your tooth together. An indirect filling (onlay or inlay) is a midrange option when the cavity is too large for a filling but not big enough for a crown.

Think you have a tooth that needs a filling? Contact your dentist to schedule an exam.
