If you’ve had a cavity at some point in the past and gotten it filled, you might think you’re in the clear—the tooth is sealed, so nothing bad can happen to it, right?
Unfortunately, tooth decay can still happen underneath a filling, especially if the filling has been cracked, worn, or otherwise damaged. In these cases, bacteria can enter your tooth and a new cavity can start again.
What are the signs you might have a cavity forming underneath your filling?
You Have a Toothache
You may have mild to severe pain radiating from one of your teeth. For some people, this pain will extend outward into their jaw or can even cause headaches. A toothache isn’t only a sign of a cavity forming underneath a filling—it could signal a cavity in one of your other teeth as well. Other symptoms of a toothache include a bad taste in your mouth, a fever, or swelling . Be sure to see your dentist as soon as possible if you have any of
You Have a Discolored Spot on Your Tooth
If your filling is a composite resin filling, it should match the natural color of your teeth and not stand out in any way.

Your dentist can evaluate the integrity of your fillings during your regular checkups to ensure they’re intact and doing their job !
The Filling May Have Fallen Out
For some patients, it’s obvious when a filling falls out, but for others, this isn’t so. When a filling becomes damaged, it’s possible that the entire restoration can fall out. You may have seen pieces of the filling or the whole filling may have come out. While this may or may not be accompanied by pain, if you suspect your filling has come out, it’s time to see your dentist.
