I have noticed for a few years now, maybe 10 lol

A couple of my rear lower molars have like a little hole or pit on the very point of the cusp. The one tooth has a fliingin it on the cheek side.

My dentist has seen these many times and has never mentioned doing anything to them. Its just like you took a small diameter drill and broke it thru the surface of the tooth, again out on the cup not in the center of the tooth.

Are these a problem ? I assume not because I have had them for awhile

Thanks AGAIN
