What branch of dentistry focuses on the prevention and correction of teeth alignment issues?

The branch of dentistry that focuses on the prevention and correction of teeth alignment issues is orthodontics. This specialty specifically addresses problems related to the positioning of teeth and jaws, using various appliances like braces and aligners to improve alignment and functionality. Orthodontists undergo additional training beyond general dentistry to master the complexities of designing treatment plans that guide teeth into their proper positions, which can enhance both dental aesthetics and overall oral health.

The other fields mentioned, such as oral surgery, endodontics, and periodontics, deal with different aspects of dental health. Oral surgery focuses on surgical interventions for various dental issues, endodontics deals primarily with the dental pulp and root canal treatments, and periodontics centers on the supporting structures of the teeth, including gums and bone. Each of these specialties has its unique purpose, but none specifically addresses alignment issues like orthodontics does.
