Dental treatment with CHAS does not have one fixed price. The amount you pay depends on the clinic's charges, the treatment you receive, the CHAS subsidy you qualify for and GST where applicable.
CHAS provides a subsidy for eligible dental procedures at participating clinics. It does not necessarily cover your entire dental bill. For example, a CHAS Blue cardholder can receive up to $30 for scaling and up to $615 for a permanent crown, but the final amount you pay depends on the clinic's actual fee and whether the full subsidy applies.
Key Takeaways
CHAS dental subsidies are maximum subsidy amounts, not fixed treatment prices.
Your out-of-pocket cost depends on the clinic's fee, applicable subsidy, GST where applicable and treatment requirements.
CHAS Blue provides subsidies for selected dental procedures, including scaling, fillings, root canals, crowns and dentures.
From 1 October 2025, MOH introduced fee benchmarks covering 18 common CHAS dental procedures.
MOH fee benchmarks are reference ranges for routine and typical cases, not price caps.
For multi-visit procedures such as crowns, dentures and root canals, the CHAS subsidy can generally only be claimed after the procedure is completed.
CHAS clinics are required to provide itemised bills showing the charges, CHAS subsidy and amount the patient pays.
At a glance
What affects your final bill? | What it means |
Clinic's treatment fee | Clinics may charge different fees |
CHAS subsidy | Reduces the eligible amount by up to the applicable subsidy |
GST | Applies to GST-registered clinics and is included before the CHAS subsidy is applied |
Treatment complexity | Your clinical needs can affect the fee |
Claim limits | Some CHAS procedures have limits on how often they can be claimed |
MOH fee benchmark | Provides a reference range for common procedures |
The basic calculation is:
Amount payable by patient = Total clinic charges − CHAS subsidy
For GST-registered CHAS clinics, GST is included in the total clinic charges before the CHAS subsidy is applied.
How Does CHAS Reduce Your Dental Bill?
CHAS provides subsidies for selected dental procedures at participating dental clinics. The subsidy amount depends on your CHAS card tier, the procedure and the applicable claim limits.
For a CHAS Blue cardholder, for example, scaling has a maximum subsidy of $30 per claim. If the clinic's applicable charge is $50 and the full $30 subsidy applies, the remaining amount would be $20 before considering any applicable GST treatment in the clinic's bill.
The example is for illustration only. Your actual bill depends on the clinic's charges and whether the procedure meets the CHAS claim guidelines.
The CHAS dental subsidy schedule provides the current subsidy amounts and claim limits.

How Much Can CHAS Blue Subsidise for Common Dental Treatments?
CHAS Blue provides subsidies for selected basic, preventive and restorative dental procedures. The current maximum subsidy amounts include the following:
Dental treatment | Maximum CHAS Blue subsidy |
Consultation | $20.50 |
Polishing | $20.50 |
Scaling | $30.00 |
Topical fluoride | $20.50 |
X-ray | $11.00 |
Anterior extraction | $28.50 |
Posterior extraction | $68.50 |
Simple filling | $30.00 |
Complex filling | $50.00 |
Re-cementation | $35.00 |
Permanent crown | $615.00 |
Complete removable denture | $408.50 |
Partial simple denture | $304.00 |
Partial complex denture | $385.50 |
Denture reline or repair | $75.00 |
Anterior root canal | $326.00 |
Premolar root canal | $462.50 |
Molar root canal | $584.50 |
These are maximum subsidy amounts, not the amount that every patient will receive or the price of the treatment.
Some procedures also have claim limits. For example, CHAS Blue allows up to two scaling claims per calendar year, while root canal treatment has a limit of up to two root canal treatments per calendar year, shared across the different types.
The dentist must also make a clinical assessment to determine whether the treatment meets the applicable CHAS claim guidelines.
How Much Does Scaling Cost With CHAS?
For CHAS Blue, the maximum subsidy for scaling is $30 per claim. The claim limit is up to two scaling procedures per calendar year.
MOH’s current fee benchmark for scaling is $35 to $60, excluding GST. These benchmarks are intended as a reference for routine and typical cases at private dental clinics in the primary care setting, according to the Ministry of Health.
For example, if a clinic charges $50 for scaling and the full $30 CHAS Blue subsidy applies, the subsidy would reduce the amount by $30, leaving $20 before applicable GST treatment.
Your actual bill may differ because the clinic's fee may be outside the benchmark range, the full subsidy may not apply or other charges may be involved.
Check the MOH dental fee benchmarks before comparing a quoted dental fee.
How Much Does a Filling Cost With CHAS?
CHAS Blue provides up to $30 for a simple filling and $50 for a complex filling.
MOH's current fee benchmarks are:
Filling type | CHAS Blue subsidy | MOH fee benchmark |
Simple filling | Up to $30 | $65 to $160 |
Complex filling | Up to $50 | $80 to $180 |
The benchmark is intended as a reference range rather than a fixed price. According to the Ministry of Health, it applies to routine and typical cases, while actual fees may vary depending on clinical and individual factors.
For example, if a simple filling costs $100 and the full $30 CHAS Blue subsidy applies, the remaining amount would be $70 before applicable GST treatment.
The final amount depends on the clinic's fee, your dental condition, the treatment provided and the applicable CHAS claim requirements.
How Much Does a Root Canal Cost With CHAS?
Root canal treatment can have a higher out-of-pocket cost because the treatment itself can be more expensive and may involve multiple visits.
For CHAS Blue, the maximum subsidies are:
Anterior root canal: $326
Premolar root canal: $462.50
Molar root canal: $584.50
MOH's current fee benchmarks are:
Root canal treatment | CHAS Blue subsidy | MOH fee benchmark |
Anterior | Up to $326 | $400 to $775 |
Premolar | Up to $462.50 | $500 to $900 |
Molar | Up to $584.50 | $872 to $1,400 |
The benchmark is not a guaranteed treatment price. For example, if a molar root canal costs $1,000 and the full $584.50 CHAS Blue subsidy applies, the remaining amount would be $415.50 before applicable GST treatment.
For procedures involving multiple visits, including root canal treatment, the CHAS subsidy can only be claimed after the procedure has been completed. The procedure must also be completed before the CHAS card expires.
Before starting treatment, find out more about CHAS dental subsidies and claim conditions.
For more information about the treatment itself, see EZ Dental Care's root canal treatment page.
How Much Does a Dental Crown Cost With CHAS?
A permanent crown has a maximum CHAS Blue subsidy of $615, subject to the applicable claim conditions. CHAS Blue allows up to four permanent crown claims per calendar year.
MOH's fee benchmark for a permanent crown is $750 to $1,400, excluding GST.
For example, if a permanent crown costs $900 and the full $615 CHAS Blue subsidy applies, the remaining amount would be $285 before applicable GST treatment.
This does not mean every crown will cost $900. The actual fee depends on the clinic and the clinical circumstances.
MOH's fee benchmarks are not strict fee caps. They are reference ranges designed to help patients and dentists discuss treatment charges and make more informed decisions.
For more information about crowns, see EZ Dental Care's dental crowns and bridges service page.
How Much Do Dentures Cost With CHAS?
CHAS Blue provides subsidies for several types of removable dentures.
Denture treatment | CHAS Blue subsidy | MOH fee benchmark |
Complete removable denture | Up to $408.50 | $500 to $818 |
Partial simple denture | Up to $304 | $320 to $603 |
Partial complex denture | Up to $385.50 | $450 to $750 |
Denture reline or repair | Up to $75 | $80 to $150 |
The amount you pay depends on the clinic's actual fee and the applicable subsidy.
For example, if a complete removable denture costs $600 and the full $408.50 CHAS Blue subsidy applies, the remaining amount would be $191.50 before applicable GST treatment.
CHAS states that for procedures involving multiple visits, such as dentures, the subsidy can only be claimed after the procedure has been completed. The procedure must also be completed before the CHAS card expires.
For more information about dentures, see EZ Dental Care's dentures service page.
What Are MOH Dental Fee Benchmarks?
MOH dental fee benchmarks are reference ranges for 18 common dental procedures covered under CHAS. They are intended to help patients understand typical charges and have more informed discussions with their dentists. (Ministry of Health)
The benchmarks cover routine and typical cases at private dental clinics in the primary care setting. They take into account common variations in patient condition and treatment complexity. They are not price caps, so a clinic's actual fee can be higher or lower depending on the circumstances.
What are the current MOH fee benchmarks?
Dental procedure | MOH fee benchmark |
Consultation | $21 to $31 |
Anterior extraction | $70 to $120 |
Posterior extraction | $93 to $164 |
Simple filling | $65 to $160 |
Complex filling | $80 to $180 |
Complete removable denture | $500 to $818 |
Partial simple denture | $320 to $603 |
Partial complex denture | $450 to $750 |
Denture reline or repair | $80 to $150 |
Permanent crown | $750 to $1,400 |
Re-cementation | $70 to $131 |
Anterior root canal | $400 to $775 |
Premolar root canal | $500 to $900 |
Molar root canal | $872 to $1,400 |
Polishing | $26 to $38 |
Scaling | $35 to $60 |
Topical fluoride | $21 to $31 |
Periapical, bitewing or occlusal X-ray | $16 to $33 |
Orthopantomogram X-ray | $65 to $104 |
Note: Although the benchmark framework is described as covering 18 common CHAS dental procedures, some procedure categories, such as X-rays, contain more than one examination type within the published benchmark table.
The Dental Fee Benchmarking Advisory Committee developed these benchmarks after reviewing past CHAS claims and considering factors such as treatment complexity, fee clustering and the reasonableness of the benchmark ranges. The committee also consulted professional associations and dental clinics.
This provides useful context when comparing a dental quotation. A fee above the benchmark is not automatically inappropriate, because the benchmark is not a cap. Instead, you can ask the dentist why the quoted fee differs from the reference range and whether there are clinical factors affecting the cost.
Why Can Two Dental Clinics Charge Different Amounts?
Dental fees can vary between clinics because treatment costs can depend on factors such as the procedure, materials, clinical complexity and the clinic's charges.
CHAS does not require every clinic to charge exactly the same price. Instead, MOH's fee benchmarks provide a common reference for patients and dental providers.
Since 1 October 2025, CHAS dental clinics have been required to display the relevant fee benchmarks alongside their price lists. This is intended to help patients have more informed discussions about treatment options and costs.
The benchmark should therefore be treated as a comparison tool, not a promise of what your treatment will cost.
Does GST Affect the Amount I Pay?
Yes. GST can affect your final dental bill.
For GST-registered CHAS clinics, GST is added to the clinic's fees before the CHAS subsidy is applied.
This means you should not simply subtract the CHAS subsidy from a quoted pre-GST treatment price and assume that figure is your final payment.
For example, ask the clinic for an itemised breakdown showing:
Treatment fee
GST, where applicable
CHAS subsidy
Final amount payable
CHAS requires clinics to issue itemised bills to CHAS patients. The bill should show the total charges, CHAS subsidy and remaining amount payable.
Can CHAS Make Dental Treatment Free?
CHAS can sometimes cover a significant portion of an eligible treatment, but you should not assume that it will make the entire bill free.
The subsidy is capped at a maximum amount for each eligible procedure. If the clinic's charges exceed the applicable subsidy, you pay the remaining balance.
For example, a permanent crown has a maximum CHAS Blue subsidy of $615. If the applicable clinic charge is $900 and the full subsidy applies, there would still be a balance after the subsidy.
The actual amount depends on the treatment fee, applicable CHAS subsidy, GST where applicable and the claim requirements.
What Should You Ask Before Agreeing to Dental Treatment?
Before starting treatment, especially for higher-cost procedures such as crowns, dentures or root canals, ask the clinic for a clear cost breakdown.
MOH recommends asking about the required procedure, expected fee range, comparison with the relevant fee benchmark and any additional charges.
Useful questions include:
What treatment do I need?
Are there alternative treatment options?
What is the total clinic fee?
How much CHAS subsidy can I receive?
Is the quoted fee within the relevant MOH fee benchmark?
Does the quoted amount include GST?
Are there additional charges?
How many appointments are required?
When can the CHAS subsidy be claimed?
How much will I need to pay in total?
This gives you a clearer picture of your actual out-of-pocket cost rather than relying on the subsidy amount alone.

Ask the clinic for an itemised bill or cost estimate showing the treatment charge, applicable GST, CHAS subsidy and remaining amount payable. CHAS clinics are required to provide itemised bills to CHAS patients.
Conclusion: Dental Treatment Cost with CHAS
CHAS can reduce the cost of eligible dental treatment, but the subsidy is only one part of your final bill. Your actual out-of-pocket cost depends on the clinic's fee, the applicable CHAS subsidy, GST where applicable and the requirements for claiming the subsidy.
Before treatment, compare the quoted fee with the relevant MOH fee benchmark and ask for an itemised cost breakdown. This is particularly useful for higher-cost treatments such as root canals, crowns and dentures.
For current subsidy amounts and claim limits, check the CHAS dental subsidy schedule and use the MOH dental fee benchmarks as a reference when discussing treatment costs with your dentist.
