There is a tiny space between my gum line and crown. Is this a concern and cavity developing later down the road? (Photo)

1. If the crown is made from zirconia (specifically "porcelain-fused zirconia" is what would be used in the anterior, as it's more esthetic), it can better mask the tooth underneath it. 2. A procedure called internal bleaching may be able to be done to lighten the "dead" tooth underneath before...

Removal of old crowns, scanning or impressing the teeth and replacing the crowns with temporary crowns can be a one-appointment process. If the dentist who works on you has a milling machine, it can theoretically all be done in one visit. You should have minimal or no sensitivity/pain thereafter...

You can eat whatever you want with your crowns. This is the rationale behind crowns. If the treatment is done ideally, you don't have to be in panic
