Class 1 - Spacing
Many times spacing is the result of the teeth being too small for the jaws; this can be “microdontia” (small teeth); it can be an imbalance between the force of the tongue versus the cheeks and lips; and it can be a functional or periodontal problem.
The most common method of closing the spaces between teeth is to enlarge them; this is usually done by adding composite (a form of plastic) to the teeth. A more permanent restoration involves the attachment of a porcelain chip called a veneer. In more compromised cases, the teeth can require the placement of a full-coverage crown.
