Having a rotten tooth can be a painful and uncomfortable experience. It can cause a range of symptoms, from continuous pain that keeps you awake at night to occasional throbbing pain without an obvious cause. You may also experience tooth sensitivity, tenderness or pain when eating or drinking something hot, cold or sweet. Other signs of a rotten tooth include the appearance of gray, brown or black spots on your teeth, as well as bad breath.
Additionally, you may be sensitive to changes in temperature, such as when drinking hot or cold beverages. This can cause sharp pain or tenderness after eating or drinking something that is not at room temperature. These symptoms can help you determine if you have a rotten tooth.
