Stupid will I know if I have cavity?


My teeth have been sore the last few days and it just made me think about something. How would I know if I had cavity? After I brushed my teeth tonight I saw that on 3 of my teeth there is black in the middle between the cracks of those 3 teeth. Can cavities be on the top like that? is that maybe just plaque or..

thanks so much..

Re: Stupid will I know if I have cavity?

Plaque is not black. And there's no way to know if you have a cavity without seeing your dentist. Some cavities will hurt if they've been there for awhile, but most will not, and the only way you know you have one is either your dentist will see it while looking at your teeth, or with an x-ray. I assume you DO go to the dentist every 6 months, correct? If you don't, then yes, those could be cavities you're seeing - and feeling - because you've left them long enough to become visible. The only way to know for sure is to see your dentist, as cavities left too long can result in either root canals or lost teeth.

You can't see the actual cavity if it's down in your tooth, but the black spots you do see could very well be cavities. We don't usually have black spots on our teeth, so you may wish to go have them check, as if they truly are cavitites, they won't go away.

That can be decay, have your dentist look and scan with the cavity detecting laser. It is the best instrument we have today for early detection and prevention. Stain will collect in the grooves of the teeth, esp from coffee or tobacco, so it is hard to distinguish between stain and caries(decay) without the diagnodent laser.

Re: Stupid will I know if I have cavity?

I once had the same issue. I found a little black dot on my tooth. It turned out that it wasn't a cavity. The dentist said that it was just a natural formation in my tooth and that I didn't need to worry about it. That was 5 years ago, and so far there have been no problems.

Really, only a dentist can tell if you have a cavity. They will take their little probe and stick it in those areas that look suspicious. My understanding of it is that they can tell either by how deep it is or by what it feels like, if you have a cavity or not. They can also tell with x-rays.

Here's the key. Don't think that your tooth is supposed to hurt if it has a cavity. If it hurts, you not only have a cavity, you are probably going to have to have a root canal (expensive and not fun).

I would recommend that you get it checked out sooner rather than later. I once waited on getting a cavity checked out that I thought was a cavity, and I wound up with a gigantic filling. The dentist told me that if I had waited much longer, there wouldn't have been much tooth left.
