What Causes Dental Pain?
Dental pain can result from:
Dental decay: Moderate dental decay can result in sensitivity to sweet foods and beverages and even some sensitivity to temperature. Eventually, though, if the decay gets into the nerve of the tooth, it can cause inflammation/irritation as well as infection. When this happens, you might experience throbbing or sharp pain that is constant.
Injury/trauma: Dental trauma can consist of trauma to the teeth, gums, other soft tissues, jawbone, and jaw joint. Injury and trauma can result from getting hit in the face during sports or an accident. It can also result from constant clenching and grinding of your teeth, which can cause muscle, jaw joint pain, and tooth pain.
Misalignment: When your teeth and/or jaw aren’t aligned properly, you can end up with tooth soreness, headaches, and muscle pain. In some cases, you might even have difficulty opening and closing your mouth (lockjaw) or earaches.
Exposed dentin: The second layer of a tooth is called dentin, which is very porous. When enamel wears down or is missing due to chipping or a tooth fracture, the dentin is exposed. Because it is so porous, whenever you breathe cold air or eat hot/cold foods, you may experience tooth sensitivity.
Infection: An infection is the result of deep dental decay that gets into the nerve or a gum infection that’s caused by periodontal disease or food/object impaction in the gum tissue.
