In your case without clinical examination and x-ray it is
not possible to give the treatment plan. If the tooth structure is enough and
the roots are fine then the Root Canal can be done, even if one side is below
the gum line. In such cases if the
dentist feels that the prognosis of the root canal treatment is good and roots
can be saved then after doing the root canal treatment post and core is done.
Post and core builds the lost tooth structure. After giving the post and
building the core ,the crown is given and the tooth will just do fine but this
is possible only if the dentist feels that the root canal treatment will be
successful. In your case, from your description it looks like that half of the
tooth is gone but other half that is back top is left. So in my opinion Root
canal treatment with post and core followed by crown should be good. If it is
not possible then you have to go for the extraction of the tooth followed by
implant. For more information on root canal treatment and post and core you can
