It is NEVER too late. My father was 60 when he had his wisdom teeth taken out. If they're problematic, see a dentist ASAP. My gums got infected and they were painful - had to wait 4 swelling to go down before they did anything.
You can have your wisdom teeth removed at any age. Many people get them out in their late teens, but that is just to prevent future problems. See your dentist and get an oral surgeon.
It might be too late, as wisdom teeth that are not pulled when you are younger can sometimes fuse with the jaw. Only a dentist can determine if this is the case, so you should see one.
No, it is not too late to have your wisdom teeth removed. However, it will be more painful because you are older and your bone is more dense and hard. Please consult your dentist as soon as possible.
