A dentist is a medical professional who has completed a Doctor of Dental Medicine (DMD) or Doctor of Dental Surgery (DDS) degree program and is licensed to practice dentistry. Dentists are trained to diagnose and treat a wide range of oral health issues, including cavities, gum disease, and oral cancer. They also perform preventative care, such as cleanings, and perform procedures such as fillings, extractions, and orthodontics.
An oral hygienist, on the other hand, is a licensed healthcare professional who has completed a degree in dental hygiene. They are trained to clean teeth, take X-rays, and educate patients on how to maintain good oral health. They may also be involved in the administration of anesthetics or fluoride treatments. Oral hygienists work under the supervision of a dentist and typically do not diagnose or treat oral health issues.
