Re - Root Canal on Tooth #7?

Hello. Can someone help me. I had a root canal and crown on this tooth years ago. Last June my dentist rebridged my front teeth to 4 teeth with this one that was just fine. When he did it, I had pain biting into the tooth. That bridge was removed and redone, still problems. Now I got implants on 9/10 done 2 weeks ago, but tooth 7 is showing a mass on the top from the trauma, needs to have another root canal, but the dentist couldn't get to it. I have an appointment with the endodontist today. Should I save it or pull it? Is surgical root canal promising? Will this weaken the tooth? Dentist wants to pull it and bridge it. Asked about another implant but the space is tight to fit implant in this area. So that would be a risk too. Only thing promising is the bridge. What would you do? HELP ME

Re - Root Canal on Tooth #7?
If it were me I would have the root canal and attempt to save the tooth if at all possible. If the root canal failed then I would look at other options.
Reply:Try to save the tooth via retreatment .The qualities of a real tooth [even if it's endodontically treated] cannot be achieved by a bridge or a implant.There is 30% chance your body may reject the implant.
Reply:it is really difficult for the dentist to reach tooth # 7 to have a root canal. But it is much much better to save the tooth rather than to pull it. teeth are like diamonds treasure them. :)
Reply:Depends on your priorities:


(1) Re treatment - root canal treatment is usually 96% successful in the first instance, but its success rate drops to around 60-70% for a second attempt. This is probably related to further weakening of the tooth structure as the root filling is re-accessed. If you'd take the risk, an endodontist is, indeed, the way to go, as they will give you a better chance of success. If the tooth you're talikng about is a lateral incisor, these teeth are always difficult to re-treat, given that they are so narrow and have a tendency to fracture, eve after crowning (Sorry, I'm from Australia, and our notation is a bit different!)


(2) Removal and replacement - you can consider removal, but if bridgework is considered, the hygiene aspect of that must be considered, as flossing under it can be quite tricky, and requires some dexterity. As one gets older, this can be an issue. If your tooth is unsalvageable, though, you have no other choice; an endodontist can assess this.


Let's be honest, there are no right or wrong answers, just choose one that suits your expectations and finances, and be happy with your decision. Go through all pros and cons, and make your decision from there. Good luck, I hope it works out for you!
