New Crown Feels Loose, Doctor Says Its Ok. Whenwill It Feel Solid?

I'm not sure why the crown feels loose! It either means the cement is not holding, or else the actual tooth under the crown is loose in the bone. Either event is not right. The dentist should have you back in to check the occlusion (the way the crown hits the opposing tooth), check the mobility of the crowned tooth, and check if the cement is holding. Sometimes it takes a day or 2 to get used to the new crown. Beyond that, it should feel "normal".

New crowns should not feel loose . Old crowns should not feel loose either. You need to have your dentist check them. if your tooth has mobility, it is even a greater concern, Please go to your dentist and get answers.
