No More Air Polishing or Prophy Paste! Revolutionary New Technique for Non Mechanical Prophylaxis – PDP284

Have you ever removed plaque using a scaler or ‘air-polisher’ and notice that the demineralised enamel flaked away?

Scaling and polishing is a routine part of preventive dental care — but could some of our traditional cleaning methods be doing more than we realise? A whitening specialist who works without a drill, scaler or air polisher argues that some approaches to cleaning may affect the enamel, and that hydrogen peroxide gel can remove plaque without touching the tooth surface.

Dr Wyman Chan has done nothing but tooth whitening since 2002, when he closed his general practice for a dedicated whitening centre, and he developed the chemical-polishing gel which is at the centre of this episode. He is joined by Dr Niki Shah, a UK general dentist and practice owner whose company distributes the product in the UK, and who now runs most of his hygiene this way.

In this episode, they explain which patients they believe may benefit most, walk through the full chairside protocol, and discuss the limitations of the approach and where it may not be appropriate.

Protrusive Dental Pearl: Manicuring Worn Lower Incisors

Worn lower incisors sit sharp against the upper teeth, concentrating stress. Take a Sof-Lex disc and manicure them, rounding the edges from pointed to smooth. Show the patient in the mirror first and, borrowing Dr Michael Melkers’ framing, ask if you can make their teeth look a little younger. It is surface topography, changed for force management, and the patient feels it with their tongue.

What You’ll Take from this Episode:

• On sound enamel, prophy paste and air polishing are low-risk; on demineralised enamel hidden under plaque, the same abrasion can flake the surface.
• Chemical polishing does not lift calculus; where calculus is present, ultrasonic or hand scaling is still required.
• Dr. Wyman Chan offers a 3% hydrogen peroxide gel as a plaque and biofilm adjunct, not a replacement for oral hygiene instruction.
• The strongest cases for this are anxious, paediatric, orthodontic, special-needs and geriatric patients who tolerate scraping poorly.
• The chairside protocol runs about twelve minutes and still ends with manual agitation using a single-tufted brush.
• No published evidence supports the product’s clinical claims yet; Dr. Wyman Chan describes studies in progress.

Aim & Learning Outcomes

Aim: To give a mechanism- and evidence-aware view of chemical polishing as an adjunct for plaque and biofilm removal: where mechanical polishing can harm demineralised enamel, which patients the approach suits, how the chairside protocol runs, and the limits of the current evidence.

By the end of this episode, dentists will be able to:

1. Describe how the abrasivity of prophylaxis pastes and air-polishing powders interacts with sound versus demineralised enamel.
2. Identify the patient groups for whom a non-mechanical approach to plaque removal is most appropriate, and the situations, such as calculus, where it is not.
3. Evaluate the current evidence base for a 3% hydrogen peroxide chemical-polishing protocol, and apply appropriate attribution and consent where the evidence is not established.
