I just broke one of my front tooth right at the gum line the tooth had previous root canal and has crown. what should i expect in terms of treatment?

Sev. possibilities: If your tooth has enough structure remaining to be restored, it may need a buildup filling possibly with a strengthening post. You may also need a periodontal procedure called crown lengthening to reshape the supporting bone of that tooth. If there isn't enough tooth structure left, it may require extraction and replacement. A thorough dental exam should tell you the options.

See dentist: Need a radiograph and clinical exam to evaluate. Did the tooth have a post? Is there a vertical fracture in addition to the horizontal fracture? There are many variables, if the tooth is deemed salvagable, crown lengthening is an option to provide more room. If the tooth is vertically fractured, an implant may be a better option, have dentist evaluate ASAP.

Many Options: It really depends on how much tooth structure is left, periodontal support, condition of adjacent teeth, and finally long term prognosis. A new crown with a post is an option, as is a bridge. A dental implant can also replace the tooth if it needs extraction. Have your dentist explain your options and his/her reasoning.

See Prosthodontist: See the specialist for evaluation and options. Age is a factor in considering the best long-term options. Likely an implant is the tx. of choice, unless there is significant tooth left above the tissue. If it had root canal tx. and broke, not a good idea to try again and expect a good prognosis. Make the appt, weigh your options, get 2nd opinion if needed. Good Luck.

See a dentist: for consultation, x-rays and treatment options. The treatment only be determined by the dentist who can see the current extent of damage. Good luck.

Several options: There are several options depending on the condition of the remaining piece of root and the surrounding teeth. 1) Please a post and core into the existing root and then a new crown. 2) Extract tooth and place implant and new crown. 3) Extract tooth and place bridge supported by surrounding teeth. Your dentist can help guide you towards the best treatment for your particular case.
