A big reason for developing and writing this website, was to give you some honest independent information so that you would have realistic expectations about what can be done and what to actually expect from the various dental treatments available today.
Not just for now, but for the future too. Of course there are going to be good and bad extremes, but having a genuine realistic appreciation is important for you to make a proper informed decision and if things do go wrong (as they do) then it will not come as an utter shock, because you were aware of the risks and potential problems
of say having crowns for example.
'How things 'look' is one of the biggest areas where both yourself and your dentist need to be on the same page. A careful open discussion is always needed in this respect!
As a dentist I am asked occasionally to perform treatment that is not ideal. Sometimes it will possible to attempt the request and other times I have to gracefully decline and suggest they seek treatment elsewhere- if that is the only thing they are prepared to accept.
To give you an example, if a tooth had fractured very low down under the gum and you really didn’t want it extracted, I may be able to attempt saving the tooth as long as you were realistic about the prognosis and understood what would happen if it didn’t work. It could last 6 months or a year, perhaps longer but I couldn't say. Are you prepared to pay for this knowing how limited it maybe?
If I felt however, that it was so far under the gum that any kind of treatment I could perform would be of little benefit and was unlikely to last even a month, it would probably be wrong of me to even attempt it, despite you saying you understand the chance of it failing.
It's a difficult grey area, in which there is often no right or wrong, and which a requires a fully honest and open discussion of risks, prognosis and alternatives.
