Who should I see a hygienist, a dentist or a periodontist?
Hygienists, periodontists and dentists each play a different role in looking after your dental health, and so you will visit them for different reasons.
Your hygienist will perform your professional teeth clean and look after the health of your gums every six months. They focus on assessing your oral health and prevention of future dental problems.
Your dentist will perform your annual check-ups and look after your general dental health. If your dentist or hygienist finds evidence of gum disease they may choose to refer you to a periodontist.
A periodontist is a dental specialist whose focus is the prevention, diagnosis and treatment of periodontal disease (also known as gum disease), and in placing dental implants and performing bone grafts and gum lifts.(again copied from another website but something similar can be he content)
