I have realised that I have had a sore area/ mouth ulcer behind a front upper incisor for a few weeks now. I have had numerous dental apts cancelled because of coronavirus and was due to go next week but it has been cancelled as I am quarantining on return from Spain. Now I am really worried about it. I think maybe I have been causing more trauma with my electric toothbrush so have started to avoid that area and put some gel on it but I am worried it is something serious - anyone got any advice or experience of this please.
