Gum Disease Treatment Cost in Sydney: What You Will Pay in 2026
Gum disease — ranging from mild gingivitis to advanced periodontitis — is the leading cause of adult tooth loss in Australia. In Sydney, periodontal treatment costs $300 to $2,500 for a full course of active therapy, depending on disease severity, the number of quadrants treated, and the suburb where your practice is located. Periodontal maintenance (ongoing three- to six-monthly review cleans) adds a further $130 to $280 per visit.
Sydney is Australia’s most expensive dental market. A scale and root plane appointment that costs $180–$220 per quadrant in Brisbane or the Gold Coast will typically run $230–$380 per quadrant at a mid-tier Sydney practice, and up to $450 per quadrant at specialist periodontist clinics in Surry Hills, North Sydney, or Mosman.
Understanding the ADA item numbers on your treatment plan is the single most useful thing you can do before agreeing to a quote. Items 221, 222, and 232 cover the overwhelming majority of non-surgical periodontal treatment, and knowing what each one means lets you compare quotes from multiple practices on a like-for-like basis.
Gum Disease Treatment Cost Breakdown
| ADA Item | Procedure | Sydney Low | Sydney Mid | Sydney High |
|---|---|---|---|---|
| 011 | Initial examination | $70 | $100 | $160 |
| 022 | Dental X-rays (per film) | $35 | $55 | $80 |
| 221 | Supragingival periodontal scale (full mouth) | $140 | $200 | $320 |
| 222 | Subgingival scale and root plane (per quadrant) | $180 | $300 | $450 |
| 222 x 4 | Full-mouth scale and root plane (4 quadrants) | $720 | $1,200 | $1,800 |
| 232 | Periodontal maintenance visit | $130 | $185 | $280 |
| Full active treatment course (exam + X-rays + 4x item 222) | $900 | $1,500 | $2,500 |
Low-end figures are typical of community health centres and high-volume practices in suburbs such as Parramatta, Blacktown, Liverpool, and Burwood. Mid-range figures reflect the majority of general dental practices across Sydney. High-end figures apply to specialist periodontists and premium practices in Bondi, Mosman, Balmain, Manly, and the CBD.
For patients with severe or refractory periodontitis, surgical options such as osseous surgery or guided tissue regeneration carry additional costs of $800–$2,500 per quadrant and are almost always performed by a registered specialist periodontist.
Sydney vs Other Australian Cities
Sydney’s periodontal costs are consistently higher than any other Australian capital. The table below compares a typical full-mouth active treatment course (examination, X-rays, four quadrants of item 222).
| City | Typical Full Course Cost | Notes |
|---|---|---|
| Sydney | $1,200 – $2,500 | Highest costs; CBD and eastern suburbs at upper end |
| Melbourne | $1,000 – $2,100 | Collins Street / Toorak practices approach Sydney pricing |
| Brisbane | $800 – $1,600 | Mid-range; more variation between suburbs |
| Gold Coast | $750 – $1,500 | Lower overheads than capital cities |
| Perth | $900 – $1,800 | Coastal suburbs (Cottesloe, Claremont) comparable to Sydney |
| Adelaide | $700 – $1,400 | Lowest capital-city pricing overall |
Per-quadrant scale and root plane (item 222) in Sydney averages around $300, compared to approximately $250 in Melbourne, $220 in Brisbane, and $200 on the Gold Coast. These gaps reflect higher Sydney commercial rents, wage costs, and the concentration of specialist-trained dentists in the Sydney market.
Health Insurance Rebates
Most extras policies cover periodontal treatment under major dental, though annual limits and waiting periods vary significantly. The table below shows indicative rebates for a single item 222 at a mid-tier Sydney practice charging $300.
| Fund | Network Tier | Indicative Rebate (item 222) | Annual Extras Limit (Major Dental) |
|---|---|---|---|
| Bupa | Members First | $130 – $160 | $800 – $1,500 depending on tier |
| HCF | More for Teeth | $140 – $180 | $1,000 – $2,000 |
| Medibank | Members Choice | $120 – $155 | $800 – $1,400 |
| nib | First Choice | $115 – $150 | $800 – $1,200 |
| AHM | Network | $110 – $140 | $600 – $1,000 |
| Police Health | Any provider | $150 – $190 | $1,500+ |
Rebates shown are per-item estimates only. Your actual out-of-pocket cost depends on your specific policy tier, whether you have served the 12-month waiting period for major dental, and how much of your annual limit you have already used. Always request a pre-treatment estimate from both your dentist and your insurer before committing.
Patients with no extras cover or with depleted annual limits should contact NSW Health or the Sydney Dental Hospital (Surry Hills) to enquire about subsidised periodontal care based on clinical priority and eligibility.
Payment Plans
- In-house payment plans: Many Sydney practices offer their own interest-free payment plans for treatment courses above $500, typically requiring a deposit of 20–30% at the time of the first active treatment appointment.
- Buy Now Pay Later (BNPL): Afterpay (up to $2,000), Zip Pay, and Zip Money (up to $5,000) are accepted at a wide range of Sydney dental practices. Zip Money’s deferred interest model suits larger periodontal treatment courses if the balance is cleared within the promotional period.
- DentiCare and similar plans: Specialist periodontal clinics in North Sydney, Chatswood, and Surry Hills often offer DentiCare monthly direct-debit plans that spread the cost of a full treatment course over six to twelve months.
- University dental clinics: The University of Sydney dental programme at Westmead, the University of Technology Sydney, and Charles Sturt University clinics offer substantially reduced-cost periodontal treatment performed by supervised dental students. Waiting lists can be lengthy, but cost savings of 50–70% compared to private practice are common.
Why Costs Vary Between Sydney Clinics
Suburb and location: Commercial rents in Sydney’s CBD, Bondi, and Manly are among the highest in Australia. Practices in these locations pass higher fixed costs on to patients. Equivalent treatment in Parramatta, Strathfield, Hurstville, or Cronulla is almost always cheaper.
General dentist vs specialist periodontist: A registered specialist periodontist has completed an additional three years of postgraduate training. Their consultation fees and treatment fees are typically 30–60% higher than a general dentist performing the same item numbers. For complex or refractory periodontitis, the expertise is often worth the premium; for mild to moderate disease, a skilled general dentist will produce equivalent outcomes.
Technology and adjuncts: Some Sydney practices charge a premium for laser-assisted periodontal treatment (LAPT), locally delivered antibiotics (e.g., Arestin), or digital periodontal charting systems. These adjuncts are not universally endorsed for routine cases and add $50–$400 to a treatment course.
Practice volume and staffing model: High-volume practices in Parramatta, Blacktown, and Liverpool use dental therapists and oral health therapists to perform periodontal scaling at lower cost than dentist-led treatment. This is clinically appropriate for most non-surgical periodontal cases and is worth asking about when seeking quotes.

Frequently asked questions
How much does gum disease treatment cost in Sydney?
In Sydney, gum disease treatment ranges from around $300 for a single-quadrant scale and root plane (ADA item 222) to $2,500 or more for full-mouth periodontal therapy across four quadrants, including initial examination and X-rays. Clinics in the CBD, Bondi, and Mosman tend to sit at the upper end, while practices in Parramatta, Liverpool, and Blacktown are typically more affordable.
What is the difference between ADA items 221 and 222?
ADA item 221 is a supragingival (above the gumline) periodontal scale and clean, while ADA item 222 is a subgingival (below the gumline) scale and root plane performed per quadrant. Item 221 is used for mild gingivitis; item 222 is indicated for moderate to advanced periodontitis where calculus and bacterial biofilm have accumulated on root surfaces beneath the gumline.
Does Medicare or the Child Dental Benefits Schedule cover gum disease treatment?
The Child Dental Benefits Schedule (CDBS) covers basic periodontal scaling (item 221) for eligible children aged 2–17, up to the $1,095 cap per two-year period. Adult periodontal treatment is not covered under Medicare. Eligible adults may access subsidised periodontal care through NSW Health community dental centres, Sydney Dental Hospital in Surry Hills, or Westmead Hospital Dental.
How many sessions does periodontal treatment take in Sydney?
Mild gingivitis may resolve in one or two visits. Moderate to severe periodontitis typically requires two to four active treatment sessions (one per quadrant), followed by a review appointment and then periodontal maintenance visits (ADA item 232) every three to six months. Most Sydney patients complete active treatment within four to eight weeks.
What is ADA item 232 and how often will I need it?
ADA item 232 is a periodontal maintenance visit — a recall clean and assessment for patients who have previously received active periodontal treatment. Most Sydney periodontists and general dentists recommend item 232 visits every three to six months to prevent disease recurrence. The cost per visit typically ranges from $130 to $280 at Sydney practices.
