Ive had a root canal and a crown placed on #30 molar.  However, the reason for the root canal/crown in the first place was a cracked tooth.  The tooth in question has always been somewhat tender..its been approx 6 years.  My dentist informed me that the crack must have gone done the root and is now deteriorating under the crown.  I will probably have an implant done..the question is if I leave the deteriorating root too long will it actually harm my jaw bone.  I am on a 6 month recall with my dentist.  Thanks for your input.
Hi, Thanks for posting the query, If the tooth is infected the infection will eventually pass to the surrounding tissue, jaw bone. A course of antibiotics and analgesics will provide relief till you go for the surgery take tab almoxiclav BD, tab Mimi BD. I would suggest you to do the treatment as soon as possible. Take care!
