I have a restoration in amalgam(very good) on a 2nd inferior molar right side. It has the mesial, distal and oclusal parts restored. The lingual cusp broke but the restoration is in place and there is no damage to the restoration or the remaining of the tooth. There is no pain, just the lingual cusp is gone. Can the dentist restore just the lingual cusp with amalgam or composite and and keep the remain of the restoration because is in good shape?

  • If the lingual cusp of the tooth is fractured, then amalgam or composite filling can be given but that won’t be very successful. In case of amalgam filling, whole of amalgam filling might have to be removed and filling has to be redone. Composite filling also won’t be very successful for restoration of lingual cusp as second molar has to bear more of masticatory forces. If you get filling done to restore the lingual cusp, then it will further make the tooth weak and tooth will become more susceptible to fracture. In my opinion, it would be better if you get the fractured tooth restored with dental crown which will make the tooth to last for long time. You can get dental crown for the tooth with large filling after root canal procedure. Root canal procedure before giving dental crown will reduce any chances of infection in the tooth later on. You can get porcelain fused to metal (PFM) or metallic crown for restoration of back tooth with large filling.
