What are dental stars?

Getting long in the tooth?

And that's where the saying "Don't look a gift horse in the mouth" came from 'cos it was considered bad manners to check the age of the horse being gifted.

Silvercat, horses teeth also never stop growing. That is also known as being long in the tooth

Silvercat, yep Beavers are one example of this and rabbits too,I think?
