Thanks for your reply but for your kind information none of u told me about re root canal and if said also I dont want to do it there.After root canal u know were well that how long I suffered from mouth ulser,u said I had allergies of those tables so I got ulser, its not because of that its because of the tools u r using.I am taking the same medicine which I took there.i dont have any problem.one more thing you guys dont have to teach me about Dr Sebys experience an all . Before this also I had a issue and again I came back because of trust in him.Its not him who did the treatment.When I gave a review u gave me sudden response.insted if u were so consern then why didnt u call me to ask about this.I was suffering from pain and u have seen that.Anyways I dont what to argue with because its ur fault and you wont agree that.Thanks for the reply
