My wisdom teeth ....?!


Question:

My wisdom teeth ....?

have just come up in the last few months, but one of them came up wit a hole in the middle of it. why did this happen?


Answers:

It sounds as though the tooth has decay in it - although it is impossible to be sure without seeing either the tooth or an x-ray of it!

Teeth DO NOT form with decay already in them. There are many developmental abnormalities that can afflict teeth, but carious cavities (the only thing that truly creates a 'hole') only develop once the tooth starts coming through into the mouth.

The problem with wisdom teeth is that they often erupt very slowly, remaining partially covered by gum sometimes for years. They are also at the back of the mouth where access for cleaning may be difficult. During this time the bacteria which cause decay, together with the sugars that the bacteria feed on, can get underneath the covering gum flap, away from the reach of saliva and a toothbrush. By the time your tooth was fully through so that you could see it - bingo - you had a cavity.

Wisdom teeth with small, simple holes do not necessarily need to be removed. The difficulties and risks of the extraction need to be weighed against the difficulties of filling the tooth. In many cases a filling is the preferable option.

Either way, you need to see a dentist!
