What does orthodontic mean?
Orthodontic is an adjective describing the branch of dentistry that corrects the position and alignment of the teeth and, in some cases, related problems involving the jaws. The word commonly appears in expressions such as “orthodontic treatment,” “orthodontic braces,” and “orthodontic appliances,” referring to procedures and devices used to improve dental alignment and bite. Its roots are Greek: “ortho-” means straight or correct, while “-dontic” relates to teeth. The term is commonly associated with braces, retainers, and removable aligners, although orthodontic care can involve broader treatment of the teeth and jaw structures. It is normally used in a professional or medical context rather than as a general term for any cosmetic dental work.

"Orthodontic appliances can improve both the alignment of the teeth and the way the jaws meet."
The Greek roots behind orthodontic literally mean “straight” and “tooth,” so the word’s straightening focus is built right into its name.
