Best Answer: Pain for 2-3 days after dental filling is normal. It takes a day or two for filling to settle. As of now take OTC pain med for pain relief. If pain is very severe or if it persists beyond 3-4 days, then you can refer to your dentist for revaluation. It can be because of some high point on filling or can be because of infection still left in the tooth. Avoid eating from that side of the tooth otherwise pain will aggravate.
