How often do fillings need to be replaced?

Patient's Concern

Hello, I inherited bad teeth from my parents and I have a ton of fillings on most of my teeth. I brush and floss as recommended however, I read that fillings need to be replaced every so often.

I'm afraid that because I have so many fillings, the dentist will not be able to keep repairing my teeth and eventually I will either lose all of my teeth or have to get crowns on all of them.

Dr. Del Toro's Response

Here are some good reasons that will signal an alarm for you to get your fillings replaced: • Signs of Decay: On a closer inspection of your afflicted area, signs of decay become more visible and such should make you visit our office immediately. Decay can cause further damage if not treated appropriately. As bacteria finds a loophole to enter your oral system it would eventually increase and multiply at great pace before it can be stopped. • Chipping or Cracking: Though they may not pose a serious nature to many, but when fillings tend to crack or chip then its best they are replaced. They might come off altogether and may become a choking hazard. Running on a broken down tool is hazardous and when fillings wear off its best they are replaced, before they can cause serious damage to one’s health.

Leakage: Over the time of continuous usage there might come an instance where the filling actually leaves a gap within the tooth. This space is where saliva and bacteria can interact freely and cause further damages.

It’s best to respond to leaking fillings early on before they get out of hand.
