A traumatic dental injury, a chipped tooth, occurs when the tooth chips after a traumatic impact. Mild chipped teeth happen when only the outermost covering of the teeth (enamel) flakes. This doesn't result in symptoms. If the injury affects any front teeth, treatment may be required for aesthetic reasons. A procedure called bonding can help replace the flaked part with a tooth-colored dental resin.
If the chip is deep and exposes the second layer (dentin), abnormal sensitivity to heat and cold will emerge. This symptom is felt when the tooth is exposed to hot, warm, or cold food. Abnormal sensitivity to touch may also be present. Dentists often recommend endodontic treatment first, and then tooth crowning. Tooth crowning covers the chipped tooth with a protective material called a dental crown. Porcelain crowns are more lifelike cosmetically, and prevent fracturing of a brittle root canal treated tooth in the future.
