question: I have a small round white raised "like" bump located inside the mouth on the inside area of the gum next to my lower teeth.  It is located near a newly prepared implant. The dentist has made x-rays and has taken the crown off of the new implant to make sure there is no infection in the implant area.  None was found.  The white bump is not sore or uncomfortable at all.  If the dentist doesn't know what it is - what other doctor should I see about this?  I'm concern since my dentist does not know what this is that it may be cancer.
