My tooth, i believe to be #4 is broken to gumline shorter on outside than inside previos root canal is it salvageable? options please.

See a dentist: A tooth that has broken off at the gum line, leaving only the root, needs to be extracted and replaced. See your dentist for consultation and treatment.

Dentist : broken off teeth usually need Dentist to treat or remove and antibiotics See Dentist soon rather than later

Dental evaluation: theonly way to k ow your options is by seeing a dentist. If there is no tooth remaining above the gum line then extraction and replacement may be your only choice.

See dentist: Need to see the dentist to evaluate. The dentist will do a clinical examination to check for fractures as well as a radiographic examination to ascertain if the tooth is salvageable. The tooth may need crown lengthening to restore or a retreat if necessary. It is up to the dentist and patient to determine if long term prognosis is great or an implant is a more viable choice.

Needs to be seen: Have a local dentist evaluate the tooth. Options are a post and crown of restorable, an implant and crown if it is not.

See dentist ASAP!: From this description the most predictable solution is to remove the tooth and replace it with a dental implant and crown. Re-treating the root canal and rebuilding the tooth has a much poorer prognosis (poorer rate of success) than the implant.

See dentist: Need to be seen to determine if salvageable. Options are crown, post-crown, crown lengthening and crown, extraction and bridge, extraction and partial denture, extraction and implant.

Examination: As all tooth fractures are different your question cannot be answered without a clinical examination and possibly imaging. Generally, however, tenth fractured to the gum line, or teeth with roots decayed below the gum line, are best treated with extraction/implant/crown.
