"A dentist, also known as a dental surgeon, is a health care practitioner who specializes in the diagnosis, prevention, and treatment of diseases and conditions of theoral cavity.
A licensed dentist can carry out most dental treatments such as restorative (dental restorations, crowns, bridges), orthodontics (braces), prosthodontic (dentures, crown/bridge), endodontic (root canal) therapy, periodontal (gum) therapy, and oral surgery (extraction of teeth)”
洁牙师（Dental Hygienist）的主要工作是清洗和抛光牙齿，同时帮助患者养成良好的口腔卫生习惯。不过，洁牙师不是牙医，不能为牙科患者进行诊断和治疗。他们不能为病患钻洞、补牙、拔牙。
A dental therapist in the dental team is the provision of preventative services. Dental Therapists exist in fifty three countries
在另一些国家，比如澳大利亚，有 Oral Health Therapists
“An oral health therapist is trained as both a dental therapist and a dental hygienist with a focus on health promotion and disease prevention."
