My wisdom teeth are coming in but only the top of my gums are black where the tooth coming in. no pain just a bad taste when my tongue goes over it?

Thats the sign: you should see an oral surgeon and evaluate the situation before they become problematic. In my experience %95 percent of the times wisdom teeth have to be removed and it is always safer, easier and less painful if you get it done early on. don't wait see a dentist or an oral surgeon asap

Examination: Your body is telling you it's time to see a wisdom tooth expert, a specialist Oral Surgeon. He/she is the best resource for determining if eruption is normal or if there is a problem that requires attention. Please schedule with Oral Surgeon (ask your Family Dentist for recommendation) ASAP.
