Teeth will descend into the gums a few weeks before they push through the gums. We’re dealing with this now. He had the top front teeth descend a few weeks ago and now the bottom ones at 16 weeks. Super drooly and fussy. But nothing has popped through and according to Dr probably won’t for awhile.
Also the underside of everybody’s gums is textured and bumpy if that’s the part you mean. It’s just weird to actually see it!
It looks like thrush
