fit of crown

[lynn117]

i have a brand new crown thats one week old. it cost a month of pay but hopefully it will save my cracked tooth. its a top molar and i opted for the extra durability of all gold. i was informed that its a whopping 77% gold which i guess is really good. the bite on the tooth is perfect. my problem is there is a visible margin on the back where the crown meets the gum (or in this case doesnt meet the gum). it also feels like theres a slight ledge where the crown meets the tooth. it feels huge when prodding with my tongue but on visual examination its quite small. i know people who have had an overganging crown between their teeth which made it difficult to floss bet that is not the case here. the dentist did have to shave off a few mm of my gums with a laser during the crown prep. anyway i am scheduled for a regular exam, cleaning, and xrays in 3 1/2 months and was wondering whether i should go in sooner or am i making a mountain out of a molehill? i

the last crown he did had the laser shaving and they grew back a bit afterward to cover the margin. i hope this will happen this time. does anyone know if the ledge can be filed down without having to remove the crown? i never had one with a perfect bite first try and would hate to mess it up.

Open margin tends to encourage decay
