What are the symptoms of teeth cavities?

Depends of Severity: Cavities are holes in your teeth caused by a disease called "dental caries". The disease is caused by bacteria. In early stages you may be totally unaware of the condition. In later stages when the bacteria are encroaching on the "pulp" you may begin to feel thermal sensitivity. As the condition progresses chewing sensitivity may set in. If the condition gets worse pain + swelling may develop.

Varies: Sometimes a cavity can cause sensitivity to sweets or to cold. Sometimes it's a discoloration in the tooth. Many times, though a cavity isn't symptomatic until it is very large. It's best to see a dentist regularly for routine x-rays and exams to catch cavities when they are small and easier to fix. It's always better when you can address the problem sooner with a simpler treatment.

Many: Discoloration. Change in shape. Sensitivity to temperature change. Sensitivity to air passage. Swelling (gum boil) soreness. Outright pain. Don't delay. Call a dentist for an appointment. Dentistry isn't expensive...Neglect is.

Several: Symptoms can present as pain, discoloration of the tooth, swelling around the tooth, sensitive to hot and cold foods/liquids or air, pain when biting down, pain that radiates along the jaw and sometimes back to the ear. Etc. See your dentist for an evaluation.
