Bonding - Why Will It Fail? Use Same Build Up As for Crown and Half a Premolar Due to Decay? (photo)

Question

80% of visible tooth remains. Want to see real tooth in front. Also, can't tuck a crown under gum. What if: Tooth filled with same build-up used for crown. Plenty to grip to as tooth is hollowed leaving only enamel. Prepare surface of build-up to grip to bonding. Bond a thin layer, like any bonding. Chew stress on top, but any bonding gets stress. (Include ceramic top onlay for stress?) Premolars take FAR less pressure than molars. Where does this fail?

Clinically, there seems to me there is less than 30% sound tooth structure available with severe decay.  Radiographically, it looks even worse.  If you would like to save this tooth, bonding will not work and will fail due to severe decay with minimal tooth structure.  A viable option would be to have a root canal, post and core, crown with a possible periodontal procedure on the distal or back portion of the tooth.  There is not enought tooth structure left for an onlay.  A second option would be an extraction with immediate implant with an implant abutment and implant crown.  Good luck and trust the diagnosis and treatment of your doctor.  Keep us informed.

There are many reasons... but looking at the radiograph it appears this tooth needs a root canal first, very close to the pulp or nerve. Anything can be done but you should do whats best and that to me is root canal build up and crown or Inlay Onlay after the root canal good luck

I noticed you posted these pics a few weeks/months ago. You have very deep decay on the premolar, probably needing Root Canal Therapy. There is not enough sound enamel left on your very brittle tooth to support bonding. Consult with an experienced dentist. If the decay is so far below your gums, you might even be better off extracting the tooth and having an implant placed.
