I've had a small hole in a metallic crown on a molar for about a year. The crown replaced a ceramic crown which wore down due to tooth grinding. The metal crown has fallen off 3X as there wasn't a large amount of tooth on which to attach it to. Will this hole lead to tooth decay. My dentist only noticed the hole on my most recent isn't to reattach a month ago while I noticed it a year ago when it first fell off.

Answer: Dental crown with a hole in it The hole in your dental crown will definitely lead to decay. Sugar and acid (the things that cause decay) will get under the crown via this hole. This decay may be more extensive the longer that the hole has been there (or the longer you wait to fix it). If the tooth under the crown is too short, then you many need to have an additional procedure called crown lengthening to provide more tooth structure for a new crown to be cemented to. If the crown keeps coming off or wearing down due to grinding, then you may eventually need to have the tooth extracted and a dental implant placed to replace it. Another option would be to treat your teeth grinding with either TMJ therapy and/or a TMJ appliance or night guard.
