Hi Dear, Welcome to HealthCareMagic.
I have gone through your query & can understanding your concern.
The bump on gum above the tooth is
periapical abscess . This occur when infection travel through the tooth and form beside the gum and reach the root of the tooth.
Treatment Depends on the condition of tooth, extent of infection, bone support and root of the tooth as follow :-
- If the infection is mild and didn't affect the root of tooth the doctor will prescribe Antibiotics such as
Augmentin along with painkillers .
- If the infection is sever and root of the tooth is also get involved the doctor may perform
root canal and left open for few days for drainage of pus. In some cases
apicoectomy will be performed.
- If there is bone loss and infection is severe the extraction of tooth should be done along with prescription of antibiotics.
Do warm saline rinses several times a day and take ibuprofen (if not allergic ) or
acetaminophen for pin and swelling.
Hope your concern has been resolved.
Good luck
