[|Human|] My 7 yr old son had a bad toothache, went to Dentist, dx with a cavity and was put on antibiotics. Several days after antibiotics, he was playing and jumping and he fell and his knee came up and  hit him on the same side as the bad tooth (upper) Now it has a pea size lump there. What to do?? Been there about 4-5 days now. He says does not hurt now.
[|AI|]  Hello! Thank you for posting here. This can be an abscess formed there. A x-ray must be taken to assess if the tooth can be saved with a root canal. Extraction of the tooth or a root canal may be necessary. I suggest you to see your dentist immediately to prevent any further spread of the infection. Excessive usage of antibiotics is also not recommended. Antibiotics only subside the infection. A complete treatment is necessary to eliminate infection. Also, the age and exfoliation of the concerned tooth must be considered. A clinical and radiological examination is necessary. Regards.
