Bump on gum: It seems that her tooth might have died, hence the gray color. The red bump may represent an abscess. See a childs dentist for treatment.

Bumped tooth: You should have this checked out. She may have an abcessed tooth. Sometimes teeth recover from trauma, but sometimes they will later have a nerve die. An x-ray will tell you the status.

Bump on Gum: I would go see your childs' dentist and get it reevaluated. It could be nothing or it could be the start of an infection. It is better to be safe than sorry. Is there pus coming out of it? Sometimes it takes a few months for the nerve to die after trauma. This could be a sign that the nerve is dead.

Necrotic pulp: A tooth turning gray after trauma usually means the pulp has been damaged. Pulpal death followed by an abscess can result. The abscess at the roots end then can penetrate the bone, showing as a bump on the gum. This is called a fistula, or sinus tract stoma. Hopefully there is no root fracture and a root canal can save the tooth. See your dr asap.
Dr. Gary Sandler

Needs treatment: The blow to her tooth caused the nerve & tissues inside her tooth to become necrotic which in turn led to the discoloration. This often takes time to develop & present itself as an infection. It requires immediate treatment & she should be seen by a dentist (general dentist or endodontist) for an evaluation, which will probably require root canal therapy if the tooth is salvageable (or extraction).

The gums above my two front teeth are swollen and I need them to go back to normal within 72 hours what do I do?

Brush, rinse, floss: Brush and keep them clean, floss them gently and try rinsing with warm salt water in that area specifically. Rinse for a minute or so or as long as you can. This should help it go away. If the swelling is not going away you need to see your dentist to have it checked out. Good luck.

Can you lose your teeth because of aids?

Dr. James Merrett
Dentistry 29 years experience
Losing teeth/AIDs: Treating people with HIV and aids has come along way. Anyone who has a compromised immune system can have challenges with keeping their teeth. It is very important to stay on top of your oral hygiene as your immune system may struggle to fight the bacteria in your mouth. Furthermore, some of the medications to treat hiv/aids may cause dry mouth, which can lead to rampant decay and tooth loss.
