How long does a periodontist train for?
In South Africa, periodontics and oral medicine are uniquely combined as a single, dual-speciality, so there is one specialist pathway, not two. To register as a specialist, a dentist's pathway is broadly:
- Complete a five-year undergraduate dental degree (BChD or equivalent).
- Spend time in clinical practice and complete the required community-service year.
- Be accepted onto a specialist training programme — admission is competitive.
- Complete the four-year full-time MChD in Periodontics and Oral Medicine at a recognised South African university (the University of Pretoria programme is 48 months full-time).
- Submit and defend a clinical research dissertation.
- Register with the Health Professions Council of South Africa (HPCSA) on the specialist register as a "Specialist in Periodontics and Oral Medicine" before practising.1
The specialist degree itself is approximately four years of full-time postgraduate university training — a four-year MChD (University of Pretoria — MChD Periodontics and Oral Medicine, 48 months full-time). By international comparison, the American Academy of Periodontology specifies three additional years for US periodontists (American Academy of Periodontology — About). A general dentist's training is five years; once the postgraduate years and the community-service year are included, a specialist's whole pathway is approximately a decade. The additional years are spent largely in clinical chairs treating the conditions a general dentist refers out.
What a periodontist treats
A periodontist's clinical scope covers everything that affects the supporting structures of the teeth — the gums, the periodontal ligament, and the alveolar bone — plus the surgical placement of dental implants. The most common reasons a patient is referred include:
- Gum disease (periodontitis) — non-surgical periodontal therapy, surgical access (flap surgery), regenerative procedures with bone grafts and growth factors.
- Gum recession — diagnosing whether it needs surgical correction, performing gum grafts to cover exposed roots, and treating the underlying cause.
- Missing teeth — assessing whether a dental implant is the right replacement, placing the implant surgically, and managing the surrounding tissues so the final crown looks and functions naturally.
- Cosmetic gum problems — correcting a "gummy smile" with crown-lengthening surgery, treating uneven gum lines.
- Failing implants — diagnosing and managing peri-implantitis (gum disease around an implant).
- Maintaining the result — running a periodontal maintenance programme so the treatment holds for decades.
What a periodontist does NOT do
A periodontist does not do general restorative dentistry. The clearest way to think about it is by where the work sits:
| The general dentist works on | The periodontist works on |
|---|---|
| The crowns of teeth (fillings, crowns, root canals, bridges) | The roots of teeth and the bone and gums around them |
| Routine cleaning | Specialist periodontal maintenance after disease |
| Whitening, cosmetic work on tooth shape | Cosmetic work on gum shape and contour |
| First-line decay diagnosis | Diagnosis of periodontal and peri-implant disease |
When you have a periodontist looking after your gums and bone, and a general dentist looking after the rest, the two skill sets meet at the gum line — and the work each does respects the other. You should not have to choose between them.
How does oral medicine fit in?
In South Africa, oral medicine is not a separate qualification — it is part of the same combined specialty. The one MChD in Periodontics and Oral Medicine covers both, which is why the HPCSA registers its holders as a "Specialist in Periodontics and Oral Medicine" (University of Pretoria — MChD Periodontics and Oral Medicine). The training happens in the same university department (the University of Pretoria's "Periodontics and Oral Medicine"; the University of the Witwatersrand's "Oral Medicine and Periodontology"). The oral-medicine side of the scope focuses on:
- Diseases of the oral mucosa (lichen planus, leukoplakia, autoimmune ulcers).
- Dry mouth (xerostomia) and salivary-gland disorders.
- Burning mouth syndrome.
- Oral cancer screening, biopsy, and surveillance.
- Oro-facial pain that is not coming from a tooth.
Because there is no separate "periodontist" versus "oral-medicine" qualification to split between practitioners, both Dr Leande Kotze and Dr Christa Blignaut hold the full scope. Either of us can see you across both the gum-and-bone work and the oral-mucosal conditions, and we discuss complex cases together when a second specialist set of eyes is useful.
When to see one
Your general dentist will usually refer you. The clearest signals that a periodontist's opinion would help:
- Gums that bleed every time you brush.
- A tooth that has become loose.
- Gums that have receded so that the teeth look long.
- You are considering an implant and want it placed by a specialist.
- A previous implant has become painful or the gum around it is inflamed.
- A diagnosis of gum disease from your dentist that has not improved with cleaning.
For oral medicine:
- A mouth ulcer that has not healed after two weeks.
- A white, red, or mixed patch in the mouth that does not rub off.
- Persistent burning of the tongue with no obvious cause.
- A dry mouth that is interfering with eating or sleeping.
If you are not sure whether you need a specialist, the simplest step is to phone the practice. Reception will book you a consultation or, if the question can be answered without one, will say so.
