Why is there a hole at the top of wisdom tooth?

Hi,

Welcome to icliniq.com.

I have gone through your question. I can understand your concern. It is mostly reversible (attachment removed to protect patient identity) and depends upon your oral higeine. We can arrest the carries at till this stage only on the smooth surface because the plaque does not get accumulated on it. For that fluoridated tooth paste is sufficient. In your case, we cannot arrest it only by using fluoride supplements because there is a shallow depression. So you have to get it filled. Make sure there must not be any high point after filling. So you need to visit a nearest dentist to get it filled, there is nothing to worry about. Your oral hygiene is good and I think this had happened because of the malocclusion of this cusp in relation with the upper one. It is getting too long and we have to manage time too.
