I read this petition in disbelief.  As a general Dentist I am in awe of the one dimensional thinking that happens in our Capital. The idea that a 5 year warrantee on crown and bridge is in any way a method to protect patients is absurd.  How can I warrantee something that I have such limited control of?  Yes, I can follow through on my responsibilities to ensure that the procedure is done to the high standard that I and the extremely large majority of my fellow colleagues accomplish every day, but it is extremely naive to think that alone ensures the success of treatment. I cannot stop my patients from drinking Monster drinks and Red Bull. I cannot drag them to their prophy appointments, or floss for them. I cannot ensure that they are not immunocomprimised in anyway, or guarantee that their family physician does not prescribe medications that cause extreme xerostomia. Even great dentistry will fail given the right mix of circumstances.
