Just got out of a dental appointment and I was wondering this about Wolverine: Can he get cavities? Does his teeth regenerate? If they're part of his skeletal system, why aren't they covered in Adamantium?
No. Wolverine cannot get cavities. His regenerative powers protect him from getting any kind of general diseases including tooth decay.
- For the record, teeth are not technically bones, so they would have been immune to the process used to cover his skeleton with adamantium.
- Tooth enamel is one of the four major tissues that make up the tooth in humans and many other animals, including some species of fish. It makes up the normally visible part of the tooth, covering the crown. The other major tissues are dentin, cementum, and dental pulp. It is a very hard, white to off white, highly mineralised substance that acts as a barrier to protect the tooth but can become susceptible to degradation, especially by acids from food and drink.
His teeth are not covered in adamantium for the same reason your teeth are not covered in bone. Teeth are covered with a specialized mineral covering called tooth enamel. Only his skeletal structure was prepared to receive the Adamantium treatment.
Most metahumans with any form of low grade regeneration will likely never suffer from tooth decay due to their body's natural enhanced regenerative state.
