You need to get to a dentist ASAP its an infection. They need to pop the bumps under sterile conditions and give you antibiotics. If the antibiotics don't keep them from comming back then they have to pull the tooth and clean the infection, then the bumps will leave for good. My daughter bumped her face on a slide when she was 2 and about 6 months later 3 of her teeth had started to turn gray and she had big bumps on her gums above those 3 teeth. They would pop and bleed and then come back. One dentist said don't worry, but I did, and finally we found out that the bumps were because of infection and all 3 teeth were pulled and the bumps disappeared. Good luck, take care.
