The size of the chip is important as well as how soon you can visit a dentist. A chip that exposes the root of the tooth can be serious. Infection can set in quickly. This is not usually the case where the chip is very minor where there is minimal damage to the enamel.
Any damage to any tooth should be given medical attention as soon as possible. Sometimes a small chip can become enlarged quickly simply by biting on a chicken bone, mashing of the teeth together, or biting on a spoon while eating.
The first step is to contact your dentist as soon as the injury occurs and get the dentist's advice. Note that these are my suggestions based on personal experience. Definitely consult a dentist before applying any kind of covering to a damaged tooth. Please note that I am not a dentist.
