"orthodontics" 的定义和意义

What is "orthodontics"?

Orthodontics is a branch of dentistry focused on fixing teeth and jaws that are not straight to improve oral health and appearance. Orthodontists, specialists in this field, diagnose and treat issues such as crooked teeth and problems with how the upper and lower teeth fit together. They use techniques like braces, clear aligners, and other appliances to gradually move teeth into the right position. Orthodontic treatment not only makes the smile look better but also helps with chewing and keeping teeth clean.
