Lateral encisors are the same size on both sides. on the one side they are perfectly aligned, on the other side there are gaps on both sides of that tooth. can bonding fix this?

Bonding and Diastema: Bonding a restoration will "fix" the spacing... temporarily. Bonding composites in this instance will only last for a few years, at best. They will discolor, chip, and fall off. At your age be prepared to replace them dozens of times. In addition, one lateral will be wider than the other and your smile may look asymmetrical. Orthodontic care will provide a more lasting, natural result. Consider it

Size discrepancy: 2 solutions. One is the see an Orthodontist to have your teeth properly aligned to close the spaces. The other is to restore the lateral incisor to fill the spaces, but that will make the tooth look overly large. Please see both an Orthodontist for an Initial Examination (usually free) and your General Dentist. Between the two they can arrange the best solution for you.
