Wedge defect in dentistry is a disease that requires treatment and has little chance of self-healing. The only tissue in the body is the tooth, which is irreversible once damaged. For example, the nail will grow again after cutting, the hair will grow again after cutting, the only thing that cannot grow back is the tooth, even if it is small, it cannot come back. When it is relatively shallow, it has no effect, and it is also very shallow after filling. When it is easy to fall off, it can be maintained by itself so that it will not continue to deepen, and it should be observed more often, and if it continues to deepen, it needs to be repaired as soon as possible. However, self-healing is not possible, and any disease of the tooth can only be treated by a doctor. After a wedge-shaped defect is filled by a doctor, you should continue to observe it and improve your habits and brushing habits, and observe if the filling material falls out or if a new defect appears every time you brush your teeth. If so, seek medical attention as soon as possible.
