Sensitive tooth, fillings fell out! What do I do?

I have had fairly bad cavities in most of my molars. My dentist drilledout the cavities and put in fillings, however the fillings seemed to break off in small pieces and were mostly gone by the end of the week, leaving some EXTREMELY sensitive gaps holes in my teeth. What can I do? Am I doing something wrong with my teeth after the fillings? Will they fall out every time?

Sounds like its your dentist that needs trading in, not your teeth necessarily. But get thee to a dentist for repairs! Until then, call their office and see if they can offer you some dental wax to place over the teeth until the work can be done. Dental wax is a soft, pliable wax that is used in ERs when someone has broken a tooth in an accident to protect the inside of their mouths from cuts until they can get to the doctor. Good luck!
Reply:you should go back to dentist ive had my fillings for over 5 yrs and only one fell out the same week i ate hot pizza and chewed on gum are you doing this? then maybe that is your problem. if it hurts take tylenol till you can make it in to the office good luck
Reply:If your teeth are that bad, you need crowns, not fillings. I know they're expensive, typically $500 or more each, plus the prep work. But it's either that or lose your molars and have to have expensive bridgework or implants. Six of one....
