Does it mean you don't have cavities if your teeth don't hurt?

Answer 1

If you for-sure don't have any cavities (as in a dentist checked and there are none), it could be sensitivity to heat/cold or it could be gingivitis from not flossing properly or often enough. Gingivitis can in fact make your teeth hurt and gums "itch/hurt" in a way.

Answer 2

Unless any problem in the root or gum..

Answer 3

No. It just means the cavity has not reached the nerves inside the tooth yet. Much of the tooth does not have any kind of nerves and can't feel pain. Part of the tooth could be completely rotted away and if it had not reached a nerve, you would feel nothing at all.

That is why six month check ups are important to catch the minor cavities while they are small enough to just do a filling. By the time you feel the pain of a cavity, you already need a root canal in most cases.

Answer 4

No.

Answer 5

No, absolutely not..

A toothache generally means the cavity has been present and growing so long it has broken through into the nerve at the centre of the tooth.
That's serious - pain, infections, loss of the tooth or nerve etc.

If the cavity is found, cleaned of infection and filled early enough on, the nerve and the rest of the tooth are never affected.
The whole process can be fairly quick and painless as the work is only in the nerveless surface part of the tooth.

That's why you need to have a checkup annually, or even twice a year if you are prone to cavities.

Answer 6

No.

Answer 7

No. I learned from experience that if you ignore your teeth until they start hurting, then you may have left it too late to do deal with cavities, and you might be looking at a really expensive root canal.
Before you know it you could be coughing up $2000 for a crown on your tooth, if you waited for it to start hurting. Go to the dentist, at least once per year. And brush yer damn teeth.

Answer 8

No

Answer 9

No. Your teeth can hurt if they are sensitive to hot and cold.

Answer 10

No it doesn't. Your teeth can rot away without getting a toothache.
