Question

what shoul di say to my dentist as he has never noticed this

Answer 1

Exactly what you said in your question.

Or, just ask him for a referral to an orthodontist. Usually they're better at seeing those kind of things since jaw and bite alignment is their specialty. Then, tell the orthodontist. He'll do some X-rays and measurements and help you decide on a course of treatment from there.
