He/She Should Check
If it's been 2 months, I think they should be checked by your dentist.
That being said, it can take quite a while for a denture to become comfortable, especially if you had some teeth removed at the time your denture was delivered. But, after 2 months, he/she should at least take a look, in my opinion. Even if there's nothing he/she can do, he/she should at least listen to your concerns and check.
