Lesion on Labrador’s lip

[Mr MXT]

I’ve noticed my 7 year old labradors usually black lips have developed a large pink spot on one side and a smaller pink spot on the other.

Any ideas from the hive mind? Normal aging or something we need to be concerned about / see the vet?

Thanks!

Is it where his top teeth rub the lip?
