Yes, each tooth has its own set of roots. By having the damaged tooth extracted, it will not affect the other teeth. Was the tooth beyond saving? I mean there are other routes one can take in order to save a tooth(its $ expensive) but you still have that tooth in your mouth. I am referreing to a root canal and crown. Did your dentist offer this option? If you choose to have this tooth pulled, are you going to have one made as a partial to replace it? Just something to think about.

Thanks so much for replying but what if I just left the cavity in, I am almost sure it is too late for a root canal because the tooth is pretty dark and split down the middle horizontally, I am usually not in too much pain. I've had this cavity in for a few years though, if I left it in there are any of my other teeth at risk? Are there any possible complications? I just want to leave it in until I can save the money for a tooth implant or bridge, don't have insurance and parents don't help much:/ thanks

I totally understand what you are going through. Been where you are and done that! Now, that I am able, I have spent a fortune to save my teeth and gums. I would go immediately and have this rotted tooth extracted. Yes, this bad tooth will have an effect on your other teeth and gums. An infection will set in and then you will have major problems. You can always have another tooth made to replace the one you have pulled. Infection can spread, it can also cause heart problems. Not trying to scare you, just help you to make the right decision. I raised a daughter on my own and did not have $ to take care of my own teeth. I undertand about not having $ and parents that don't help you. I am sure there is a dentist there though that would work something out financially with you. Please take care of yourself! Lmk ! I'm out here waiting in the wings!
