Question Just had a crown placed, the crown placed does not go all the way to the gum line, barely visible in front, but even worse in the back where there is a bigger gap. I thought a crown when past or into the gum line.
Answer Dear Brian,
There is no absolute requirement that the margins of a crown be extended under the gum line. In fact, ending the margins above the gum is a recognized strategy for minimizing any harmful effects the crown may have on gum health. However, most dentists will construct their crown margins so they are positioned under the gum, because doing so will more closely simulate the appearance of a natural tooth. It will also better protect the tooth from recurrent decay in cases where high decay susceptibility is a problem.
So, visible crown margins are only an issue if you find them visually objectionable. If so, then you need to do some talking with your dentist.
Hope this helps...
