Are you interested in being a dentist or a dental hygienist? If hygienist then you can do this with an associate's or bachelor's degree. The bachelor's will allow you more opportunity such as teaching or working in public health. However, if you just want to work in a private dentist office, the two year degree will get you well on your way. After your degree you will need to get your license. You be required to become licensed in your state before you can start working as a dental hygienist. To earn a license, you would graduate from an approved program and pass an examination that includes both written and clinical components.
If you're interested in becoming a dentist, you're looking at eight or more years.
Hope this helps!!
