Hello. My daughter had a pus-filled spot on the gum above her upper central incisor. At the dentist’s check-up we learned that the tooth would have to be opened. Yesterday the dentist punctured the spot and today she also opened the tooth, that is, drilled a hole in it. The spot is smaller, which means the pus is obviously no longer accumulating. But now the tooth remains open. I asked whether she would make a filling, but she said the condition would worsen again if she did. I would like your opinion. Is some treatment necessary or has the tooth really died completely? I should mention that in July my daughter fell and this exact tooth became loose. It is still a nice white color. The dentist said it was probably a consequence of that fall. If the condition worsens, she said it might even be necessary to extract the tooth. Thank you for your answer.
