This often results in enamel loss which makes the tooth a lot more sensitive to hot and cold causing you pain and discomfort. The increased sensitivity and the damaged tooth’s surface can considerably be improved with a dental filling which is the best restorative treatment for this type of dental problem. Depending on just how much the tooth is damaged the filling can either be placed directly in the cavity or an impression of the whole tooth is made which is used for creating a custom filling that would perfectly fit the damaged area. There are four main types of fillings that can be used to effectively treat tooth decay. Knowing the main advantages and drawbacks of each type can help you decide which one is the right for you.
