Imagine the following scenario:

A busy day in practice! A patient comes in with tooth #2-6 (upper left first maxillary molar) being extremely sensitive to cold (a.k.a. a “hot tooth”).  You notice a very old, large amalgam filling on the tooth which had been done over 20 years ago.  No recent restorative changes in the area  is reported by the patient.  Breathing in air, blowing air on this tooth with an air-water syringe or applying ice to the tooth sends the patient through the roof.  All other teeth in this quadrant are responding normally to cold test. Quickly and confidently, a pulpal diagnosis is reached (irreversible pulpitis), endodontic treatment is recommended, and the need for a full coverage crown is also emphasized after root canal treatment. Simple, right?


a cracked tooth

Well, not so fast!

  • unless you stopped and thought about the reasons why the tooth became sensitive to begin with (i.e. thinking about the etiology for pulpitis and the possible pathways to the pulp),
  • unless you thoroughly examined the tooth clinically and looked for signs of cracks, leakage, caries, periodontal disease, parafunctional habits, etc.,
  • unless you grabbed a perio probe and actually noticed a 6-7mm probing defect on the distal aspect of the tooth,
  • unless you noticed on the pre-op radiograph a questionable area with respect to the quality of the crestal bone between teeth #2-6 and #2-7,
  • unless you removed the obscuring filling and gave yourself an adequate view of what lies beneath during the treatment (as opposed to those who still love to brag about their super conservative access and their beautiful final result through a tiny 2x2mm hole),

You might have missed a more serious issue with this innocent-looking tooth in need of JUST a root canal and a crown,  you may lose the opportunity to properly inform your patient of possible outcomes of your treatment and you may end up performing unnecessary treatments for a tooth with an unfavourable prognosis.
