Can you get a cavity in a tooth that already has a filling?

Do I have to worry about cavities after a filling? Yes. Just because a tooth has been filled does not mean that decay cannot still form afterward. Tooth decay starts from the outside, with bacteria turning into plaque, a sticky substance which sticks to your teeth.

What happens if you get a cavity under a filling?

If a filling has failed or decay is detected on the X-rays, the fillings will have to be replaced. If the recurrent decay is extensive, a dentist may need to use a crown to replace the filling. There may not be enough remaining tooth structure to support the replacement filling.

How does a tooth decay under a filling?

If the seal between the tooth and the filling breaks down, food particles and decay-causing bacteria can work their way between the worn filling and the tooth. These bacteria cannot be removed easily with a toothbrush or other means, and decay may develop along the edge of the filling or under- neath it.

Can you get a cavity in the same tooth twice?

How can a dentist tell if a filling is leaking?

Do cavity fillings need to be replaced?

While dental fillings can last for many years, sadly, they do not last forever. Eventually, all fillings need to be replaced due to constant stress from eating and drinking, and especially from tooth clenching and grinding. Over time, fillings can wear out, chip, crack, or even fall out altogether.

Can a leaky filling cause an infection?

Any gaps between the filling and your tooth allow saliva, bacteria, and food particles to enter. Bacteria can breed beneath the filling and promote decay (recurrent decay) that irritates your tooth, makes it sensitive to heat or cold, and causes pain. A leaky filling can lead to inflammation and infection.

What does a leaky filling feel like?

The porcelain filling is best suited if you have serious aesthetic concerns. These cover most part of the tooth, as a result, can be used if the decay is large enough. This long-lasting filling does not stain or wear off easily.

How does the dentist take out a cavity?

The dentist will use a dental drill to take out the part of the tooth that was causing you pain (the cavity). The drill shoots out a small stream of water and makes a high-pitched noise that some people may find annoying, but because the tooth has already been numbed, you won’t feel anything at this point other than some vibration from the drill.
