The front tooth is actually the easiest to do a root canal on, so it shouldn’t be bad at all. They won’t be changing your tooth much if you don’t need a cap, just cleaning out the infection and the nerve. So you shouldn’t feel any change in how it sits in your mouth or pressure against other teeth or anything like that.

I’ve had a root canal on a front tooth and the only time I can tell that it’s any different from my other front tooth is if I accidentally bump it with something, it doesn’t hurt the same way as a tooth with a nerve does. It still hurts, just from the gums rather than the tooth if that makes sense.

Don’t feel like you can’t tell your dentist you’ve had bad experiences before and are afraid, it is SUPER common and dealing with it head on is going to be a lot better than being unable to get it done during the appointment due to an anxiety attack. If you don’t feel it’s quite that bad for you then you can still ask for nitrous oxide to help you relax.
