Hello We have four teeth (2 at the bottom and 2 on top) There is one lateral tooth protruding from below, although I didn't notice that the gums were swollen. The upper gums have been swollen for a week now and I'm waiting for it to protrude, but today I noticed a lower tooth. I know that the upper lateral ones usually come out first and then the lower ones, but we're in reverse order. Is this normal? Has anyone experienced this?
