a cavity filled tooth get cavity again?

Question

I just had root canal therapy, awhile ago and i got fillings, can my tooth that had the root canal therapy, get cavity again? i mean can i feel pain when i get another cavity on that tooth?

Answer 1

You can't feel pain from it, but yes it can get caries (cavities) again. all the RCT (root canal therapy) does is remove the nerve from the tooth. your doc should have discussed crown options with you, if not, look into it. after RCT, the tooth structure is weakened, leaving the tooth suseptible to cracking and breaking. look into gold or porcelain crowns.

Answer 2

It's possible. Even cavities that get filled can get cavities again underneath or around the filling. The BEST way to keep from getting more cavities is to forgo ALL refined sugar and brush your teeth within 5 to 10 minutes of eating. If you can't do that, then swish some water around your mouth. Small cavities can heal themselves, and remineralize. Make sure to brush 2 times a day and floss once a day.

Answer 3

A root canaled tooth is dead. There is no nerve left in that tooth. It is possible for the tooth to get another cavity, but you will not feel anything. There is something called refered pain. You may feel as though that tooth hurts, but in reality it is another tooth. This is b/c all of your nerves are connected. An example...you may have pain one day on your upper molar...a few days later it feels as though that pain has traveled to the tooth below it.

Your dentist should have suggested crowning that root canaled tooth. This will prevent breakage of that tooth. Now that the tooth is dead, it is weak. Eventually, it will start to crumble.

Crowning the tooth in question will not prevent decay, but may minimize the chances. Sometimes decay can be found around the gumlines of crowned teeth. If left untreated, the decay can travel underneath the crown. To help prevent this from happening, it is important to visit your dentist bi annually for cleanings and exams and always remember to brush(atleast 2x/day) and floss(atleast once/day) at home to also aid in cavity prevention.

It's not unusual to have sensitive fillings for a while, but 2 months does seem pretty long. Sometimes, when the cavity goes quite deep, a dentist will put a base coating of a material (can't remember what it's called) to create a barrier between the pulp and the metal. Maybe this was not done. You can have them checked, but to remove and re-do by another dentist will cost you. If it keeps up by April, I would definitely have it checked out tho.

Answer 5

HI,
YES, A TOOTH CAN GET NEW DECAY IN IT AFTER HAVING A FILLING. BUT IF THE TOOTH HAD RCT ON IT, IT PROBABLY WONT HURT. ALL TEETH THAT HAD RCT DONE TO IT NEED A CROWN TO PROTECT IT FROM BREAKING. IF A TOOTH THAT HAD A RCT DONE ON IT AND IT BROKE, YOU THEN WILL FEEL PAIN ON IT. GOOD LUCK AND KEEP UP WITH YOUR CHECK UP'S AT YOUR DENTAL OFFICE.

Answer 6

ANY TOOTH THAT HAD PREVIOUS ROOT CANAL THERAPY WILL BE RENDERED BRITTLE AND PRONE TO CRACKING. A MUCH BETTER THING TO DO IS TO HAVE THIS TOOTH CROWNED.
IF YOU HAD AN AMALGAM (MERCURY FILLING) OVER THE ROOT CANAL TOOTH, THIS MAY HAVE RECURRENT DECAY WHICH SHOULD BE REPLACED - IDEALLY WITH A CROWN.

Answer 8

I think your tooth may still may be sensitive even thought the roots are dead. The filling may be causing the pain your feeling.

Answer 9

perhaps, also maybe a different tooth is causing the pain cuz the nerves are all hooked together.
