What a periodontist covers
Periodontics is the speciality that treats the gums and bone that support the teeth. A periodontist manages gum disease (gingivitis and periodontitis), performs deep cleaning, gum and bone grafting and gum-recession treatment, and places and maintains dental implants. Healthy gums are the foundation for keeping your natural teeth, so periodontal care matters even when teeth themselves feel fine.
What to expect at a consultation
A first visit usually starts with your dental history and concerns, an examination and often X-rays or a scan. The periodontist will explain what they find, outline the options with their pros, cons and typical costs, and answer your questions so you can decide without pressure.
Preparing for your appointment
Bring a list of your medicines and medical conditions, any recent dental X-rays or referral letters, and note down your main concerns and questions. If cost matters to you, it is reasonable to ask for a written treatment plan and estimate before starting.
After your consultation and follow-up
You may leave with a treatment plan, a follow-up appointment, or a referral for further care. Complex treatment is often staged over several visits, with reviews to check healing and results. Good day-to-day oral hygiene and attending reviews help protect the outcome.
Booking, referrals and fees
Many patients book directly; some are referred by their general dentist. Fees vary with the treatment and the individual case and are not quotes — confirm current charges with the clinic. Ask whether MediSave or insurance applies to any surgical portion of your treatment.
Common questions
What does a periodontist treat?
Periodontists focus on the gums and the bone around teeth — including gum disease, gum recession and the placement of dental implants.
Is gum disease reversible?
Early gum inflammation (gingivitis) can often be reversed with professional cleaning and good home care. More advanced periodontitis can be controlled but usually needs ongoing management.
Do I need a referral to see a periodontist?
You can often book directly, though your general dentist may also refer you if they detect gum problems.
