A student who wishes to treat diseases of the mouth may wish to study dentistry. Dentistry studies how to keep the teeth, gums, and other parts of the mouth healthy and how these parts interact with the body.

Associate degrees are an excellent choice for any students seeking new pathways after graduating from secondary education. These degrees can generally be completed in one to three years, although most students finish within about two years.

Part-time learning allows one to obtain a degree or qualification even if one cannot attend school on a full-time basis. One can learn at one's own pace, gradually accumulating credits that count towards a final qualification.
