Painful nipples suddenly

Megan

8 months old EBF, not pumping. Both my nipples are so tender all of a sudden, feeling almost raw. They aren't red/cracked or discolored in any way.

He has two bottom teeth but from what I can see while he's nursing his tongue is forward and has a good latch.

Has anyone else experienced this at this age? Is it just that he has a stronger suck now?
