Air polishing and traditional scale and polish are not competing treatments — they are complementary tools that serve different purposes, and understanding which you need at a given appointment comes down to your clinical situation rather than personal preference. Our hygienist team at Coniston Dental in West Byfleet uses both, selecting the appropriate approach based on what we find.
What Is a Traditional Scale and Polish?
A scale and polish uses manual scaling instruments and ultrasonic scalers to remove calculus — the hardened mineral deposits that accumulate on tooth surfaces, particularly below the gumline. Calculus cannot be removed by brushing; it requires mechanical disruption by a trained clinician. The polishing phase uses a rotating rubber cup and prophy paste to remove extrinsic stains and smooth the tooth surface.
According to the description of teeth cleaning on Wikipedia, scale and polish is the standard approach to professional dental cleaning, with the process involving careful removal of deposits above and below the gumline. The procedure takes between twenty and forty-five minutes depending on the degree of calculus present and the patient’s access conditions.
Across the people who come in for this treatment regularly, we see significantly less calculus accumulation compared with those who attend infrequently. That matters because calculus is the primary substrate on which periodontal bacteria anchor themselves.
What Is Air Polishing?
Air polishing delivers a controlled stream of warm water, air, and fine powder — typically sodium bicarbonate or glycine — onto the tooth surface. The slurry removes soft deposits, pellicle, and extrinsic stains efficiently and without the abrasive mechanical pressure of a traditional polish. It is particularly effective for stain removal from coffee, tea, red wine, and tobacco, and for cleaning around orthodontic brackets, implant surfaces, and subgingival deposits in periodontal maintenance patients.
The Wikipedia entry on tooth polishing notes that air polishing is highly effective for removing extrinsic stains and soft deposits, with minimal abrasion to the enamel surface when the correct powder is used. This makes it preferable to traditional polishing paste for patients with exposed dentine or sensitivity, where abrasive paste could cause discomfort or surface loss.
Key Differences
| Feature | Traditional Scale and Polish | Air Polishing |
|---|---|---|
| Calculus removal | Yes — primary function | No — ineffective against hard deposits |
| Stain removal | Moderate — depends on paste | Excellent — particularly for extrinsic stains |
| Soft deposit removal | Good | Excellent |
| Subgingival use | Yes (with appropriate instruments) | Yes (with glycine powder) |
| Implant surfaces | Requires care — metal instruments can damage surfaces | Suitable with appropriate powder |
| Sensitivity | Can cause discomfort on exposed roots | Generally better tolerated |
Who Benefits from Air Polishing?
Air polishing is not universally appropriate. There are contraindications: patients on sodium-restricted diets should not receive sodium bicarbonate air polishing, and it is not recommended for patients with certain respiratory conditions, as the aerosol can affect the airway. Patients with Addison’s disease or Cushing’s disease should also not receive sodium bicarbonate polishing. For these patients, glycine-based powders are an alternative, and traditional polishing methods are used where indicated.
That said, for patients who are heavy coffee or tea drinkers, those who have completed orthodontic treatment, and those in periodontal maintenance who have implants or deep pockets, air polishing offers a meaningful clinical advantage.
Which Is Better?
Neither is inherently superior. A patient with heavy calculus deposits needs ultrasonic scaling; air polishing cannot substitute for that. A patient with moderate staining but minimal calculus may benefit more from air polishing than from traditional paste polishing. Many hygiene appointments use both: scaling to address calculus, followed by air polishing to complete stain removal and clean subgingival sites.
You’ll find advice online suggesting that air polishing is simply a modern upgrade that replaces traditional methods entirely. In our experience, that’s not always accurate — the choice is clinical, not cosmetic.
- Traditional scaling is essential wherever calculus is present
- Air polishing is preferred for heavy staining and implant maintenance
- Glycine-based powder is safer for subgingival periodontal maintenance
- Contraindications apply — your hygienist will assess suitability
The Realistic Expectation
Some patients find traditional scaling straightforward with no discomfort. Others need more time and local anaesthesia for comfort, particularly around sensitive teeth or deep pockets. Air polishing, for most patients, is more comfortable than traditional rubber cup polishing — but the sensation of the water-and-powder stream takes some getting used to.
And here’s what that means in practice: the technique matters less than the regularity of attendance. A consistent six-monthly appointment with either method will produce better outcomes than an infrequent appointment with the most advanced equipment available.
