Why do I need to have my cavity filled if it doesn't hurt?
When minor, many medical conditions do not cause pain or discomfort. Dental decay is no different. When a tooth starts to hurt, it usually indicates that the cavity is deep and may require root canal treatment. It is much better to treat cavities when they are smaller because it will take us less time and we can save more of your natural tooth. Early treatment of decay can prevent more costly procedures such as root canals and crowns.
