The following treatments are available for gaps in teeth: 1. When there is a tight contact between the two adjacent teeth, the gingival flap surgery can be performed to remove the diseased bone and granulation tissue and then place bone powder and bone membrane to fill the gap and form a normal gingival papilla. 2. In case of larger gaps, the adjacent teeth on both sides can be prepared and then restored with a joint crown. 4, When there are scattered gaps in the teeth, orthodontic treatment can be performed to close the gaps by traction of the teeth.
