Hi,

Yes, it’s possible for cavity to develop under the filling. Bacteria can travel along the edges of the filling cavity travel down underneath the filling. If you have a cavity, best to have it fixed as soon as possible.

Absolutely.
Yes! This is why it is important to maintain good dental hygiene and regular dental visits.
Hello,

A tooth can get decay under a filling. The filling that was done in the tooth prior to the decay was only done to remove the decay the first time. Decay under a filling is referred to as secondary caries or secondary decay by dentists. In fact, a tooth is more susceptible decay when a filling has been placed because that filling needs to be sealed and remain sealed. Sometimes the filling can separate from the edge of the tooth just a bit which would allow bacteria back into the tooth. To make matters worse, in this case the bacteria cannot be brushed away with a tooth brush because the gap is too small for one tooth brush bristle to get into. The bacteria can travel down this gap and create decay under the filling. As decay starts he gap gets bigger and allows more bacteria, which then causes more decay. The vicious cycle begins! The key to this is having regular check ups and cleanings with a dentist which will detect a filling that is leaking before the decay gets a chance to start growing. Hope this helps.

My best to you!
