Hello, Youmay experience some sensitivity that would be considered normal. It should be with the teeth that had the new fillings and taking pain medication such as acetaminophen and ibuprofen should make you feel better. If you were told that a filling was particularly deep the sensitivity may linger especially to cold temperature. Try toothpaste for sensitive teeth and fluoride rinses for some relief to sensitivity. If your gums are sensitive and irritated from the recent dental treatment, rinse with warm salt water and use gentle techniques with brushing and flossing. There are conditions that will require you to return to the dentist for an evaluation. Does your body feel different than before you had the fillings done? You may need an adjustment to your bite. This means you have a high spot. Reducing a small amount of the new filling may relieve your symptoms. I suspect this may be your condition when you have an overall feeling of sensitivity, mainly cold sensitivity, and had more than one filling done recently, Is your pain increasing with hot sensitivity and pressure sensitivity accompanying your discomfort? This raises the concern of an infection. A very deep filling can be too close to the nerve which allows bacteria to enter causing infection. The tooth would require additional treatment such as a root canal. A less common situation would be an allergic reaction to the new materials in your mouth. Monitor your symptoms and update your dentist. Thank you for your inquiry. I hope my initial suggestions offer relief and you feel much better within a week to two weeks. If your symptoms slowly improve take care with a softer diet and avoid extreme temperatures. Continue to practice good oral hygiene and call your dentist for return visit if your condition does not improve shortly.
