It is necessary for the doctor to have x rays of the teeth so that they can provide accurate information on the health of your teeth. In many instances, cavities cannot be seen in the mouth until they are too large to be just filled. This is when x rays are of the utmost importance, that cavity could be spotted early in development and been treated without needing further more costly work such as a root canal. But most importantly, Southview dentistry uses digital x rays and a lead apron with a thyroid collar, which provides the least amount of radiation. Patients receive more radiation from their cell phones and/or microwaves from one use than they would from a digital dental x ray.
