I have been suffering from an abssess tooth going on 2 1/2 weeks.  I am scheduled to see a specialist on Thursday for a root canal; however I have developed a blister the size of a penny on the roof of my mouth.  Is it okay if I burst this blister?  Its is causing a lot of pain.
Hi. Welcome to Chat Doctor . I have gone through your query and can understand your concerns. As per your complaint the blister that has caused to you is due to pus formation below the root tips of the infected tooth which at times perforates the bone and appears as a blister below the soft tissues. It is a painful condition, but you should not prick or burst the blister as it will be further painful. You should take antibiotics like Augmenting 625 mg three times a day and Tramadol 5Omg thrice a day and Pantoprazole 4Omg empty stomach once in morning.... You can apply numbing gel over the blister for local relief. You should continue with the medicine for 5 days and by then get the root canal started so that the pus finds a way to discharge, and the condition will relieve. Hope this information helps. Thanks and regards. Chat Doctor. .
