I am very happy to read it, and even more so that I have made that decision, although it sounds crazy, people prefer to brush their teeth before undergoing root canal treatment. You have made the best decision of your life, otherwise you would be using prosthesis.

You can help when the bleeding starts with Peridont (it's a stronger mouth rinse), you should not abuse it, you can use it one week a month. It will help with gingivitis.
