What are ways to know whether i have cavities or not?

Vist the dentist: Cavities can occur in areas that can't be seen without x rays, and they don't always cause pain. If you see holes in your teeth when you look in the mirror, you probably have cavities, but the only way to know for sure is too see the experts who know what to look for. Visit your dentist!

See your dentist: The dentist will have to examine each tooth carefully. Xrays will certainly help to diagnose any cavities present.

See your dentist: Some indications for you are sensitivity to cold and sweets. However, you could have cavities and not know about it or....You could have some sensitivity and not have cavities. Only by going to the dentist for a clinical exam and x-rays will you know whether or not you have cavities (or other dental problems). That is why routine dental checkups are so important.
