If your mouth or jaw hurt, it could be from a toothache. Toothaches usually indicate a cavity but they can also signal gum disease. In some cases, a toothache is a sign of an abscess or impacted tooth. A toothache should be evaluated by a dentist right away to determine the cause of the problem and prevent the tooth from dying.
Bleeding or sore gums can be a sign of gingivitis, an early and reversible stage of gum disease, or simply the result of brushing too hard or starting a new flossing routine. If your gums bleed regularly, or enough to worry you, make an appointment with your dentist or physician, it could be a sign that something else is wrong.
