A toothache occurs when the nerve surrounding a tooth or in the root of a tooth has become irritated. The majority of dental issues can be prevented by getting professional teeth cleanings twice yearly, brushing teeth with fluoride toothpaste, and flossing. A toothache may present as anything from uncomfortable pressure to severe pain. The pain might intensify when an individual presses the tooth. Some patients also experience serious pain when their teeth are exposed to cold or hot stimuli. After removing the stimuli, the pain might continue for longer than fifteen seconds. Pain might also radiate to the jaw, ear, or cheek.

Cavities occur when there is permanent damage to the hard surface of the teeth, leading to tiny openings. Several factors can cause cavities including improper tooth cleaning, sipping sugary drinks, snacking frequently, and having bacteria in the mouth. Cavities are particularly common in older adults, teenagers, and children, though anyone with teeth can get a cavity, even infants. Cavities that remain untreated become larger and cause problems in deeper layers of the teeth. Cavities can cause severe toothaches and infection. At the start of a cavity, individuals might not experience any symptoms. More serious tooth decay might cause symptoms like spontaneous tooth pain, teeth sensitivity, pain when drinking or eating something cold, hot, or sweet, pain when biting down, and visible pits in the teeth. A toothache is a reason to see a dentist. It's also important for individuals to get regular teeth checkups, since some cavities don't cause any symptoms until they've become advanced. The destruction leads to irritated and swollen tooth pulp, which then causes nerve compression.
