I think a small, but very noticeable, part of my wisdom tooth erupted behind my second to last molar on the top row of my mouth. It looks like there is a add-on to my molar on the inside part of my gums. I had swelling for a few days on the outside gums of the same molar. Sometimes I feel pressure there too, and my last molar is completely crooked from the rest of my teeth. Should I be worried?
