Bad crown; purple and red veins around gums?

Unfortunately, without photos and more information it's impossible to give you an accurate diagnosis. I would suggest seeing your dentist to have the tooth evaluated as soon as possible. Good luck and I hope this helps. Click save on the save button below my name, so that you may ask me more questions in the future.

Hi:Without photos and X-rays it is impossible to give you an accurate diagnosis.  I suggest you get a consultation with a dentist right away to make sure the issue does not progress any further.Best,Dr. Maddahi

It's impossible to give you a diagnosis without more information and pictures. My suggestion is to schedule a visit with your dentist and have this looked at. Your dentist should be able to give you a diagnosis.
