Hello,  I had a root canal treatment 3 weeks ago and 1 week ago I had the permanent filling. A few days ago I developed a small blister in the roof of my mouth, but it has moved around from just above the tooth to the middle of the roof of my mouth.  Is this something that will go away on its own?  I had the tooth x rayed again when I had the permanent filling and it looked good.   Thank you!
Hello, Welcome Thanks for consulting Chat Doctor, I have gone through your query, as you have mentioned that you have undergone root canal treatment and again there is small blister formation on roof of mouth don't worry it is due to again formation of Periapical Pathology may be, so you do is go again to dentist and get IOWA X-ray again if there is Periapical Access then RE -RCT is treatment or if it is due to periodontal problem then go for Scaling and root planning Hope this will help you.  Wishing you good health Regards
