[|Human|] I have a capped tooth I had to have recapped about four months because I was facing severe pain in jaw when she recapped it my tooth felt fine for a couple of weeks the pain then stopped so I figure it went away but over the past month or so Ive noticed a blister typed thing over the capped tooth. Ive popped it twice but it just keeps coming back.
[|AI|]  Thanks for using Chat Doctor. Read your query. Recurrent blister in the case with the mentioned signs and symptoms suggest the presence of underlying infection in the capped tooth referred as a periapical abscess. Was the tooth root canal treated? If yes, it may require pretreatment and then followed by the capping. I would advise you to consult a good Endodontist and have a radiograph done followed by the pretreatment and then placement of the crown. Antibiotics like amoxicillin 500 mg and metro lag may be required on prescription. Do salt water gargling. Hope this was useful. Thanks and regards.
