I have pain when i chew on two very small fillings i have gotten done. one i've had redone 3 times. can you please give me advice on what to do next?

FindTheTooth'sTruth: Get on the horn and call your dentist to figure this out or find another dentist. The pressure pain indicates residual nerve sensitivity and if it gets worse could progress to cold sensitivity. It could mean an infection cooking at the root or a loosening tooth ligament. Maybe it's a chemical reaction to the filler. In any case, the pain issue should be resolved by a competent dentist.
