Who Should Get Air Polishing? Patient Selection and Clinical Indications

Air polishing is suitable for most dental patients requiring biofilm removal, including those with implants, orthodontic appliances, and sensitive teeth. The key consideration is powder selection—with glycine or erythritol powders, the range of eligible patients is significantly broader than with traditional sodium bicarbonate.

Once considered a specialized technique for stain removal only, air polishing has evolved into a mainstream biofilm management approach. Today's powder formulations and delivery systems allow clinicians to adapt the technique to diverse patient populations and clinical scenarios. Understanding who benefits most from air polishing—and how to match powder selection to patient characteristics—is essential for evidence-based practice.

Ideal Candidates for Air Polishing

Routine Maintenance and Recall Appointments

Patients in supportive periodontal therapy and routine recall represent the largest candidate group for air polishing. These patients present with biofilm and light to moderate surface stain, minimal or no bleeding on probing, and adequate periodontal health. In this population, air polishing effectively removes biofilm and extrinsic stains while requiring minimal time investment. Published systematic reviews confirm that air-polishing methods produce clinical outcomes equivalent to hand instruments and ultrasonic scaling in routine maintenance settings, with the added advantage of improved patient comfort perception.

Implant Patients

Implant patients are among the best candidates for air polishing. Titanium implant surfaces are susceptible to damage from conventional metal instruments, and research demonstrates that erythritol and glycine powders are safe and effective on titanium. Unlike sodium bicarbonate powder, which can be aggressive on implant abutments, low-abrasivity powders allow thorough biofilm removal around implants without risk of surface modification. For peri-implant maintenance and supportive care, air polishing is now considered a preferred approach. Patients with both natural teeth and implants benefit from a unified prophylaxis protocol using implant-safe powders.

Orthodontic Patients

Patients wearing fixed orthodontic appliances present a significant challenge for conventional prophylaxis: biofilm accumulates around brackets, wires, and bands in areas difficult to access with traditional polishing cups and ultrasonic instruments. Air polishing with its parallel jet of powder and water allows clinicians to direct the stream into interproximal spaces and around bracket margins without physical instrument contact. This makes orthodontic patients ideal candidates, particularly during long-term active treatment when recall visits are frequent.

Patients with Sensitive Teeth

Dental sensitivity limits treatment options for many patients. Conventional prophylaxis with rubber cups and polishing paste can trigger significant pain in sensitive patients, sometimes leading to avoidance of regular recall care. Air polishing with erythritol or glycine powder represents a gentler alternative. These low-abrasivity formulations are less likely to provoke sensitivity compared to rubber cup polishing or higher-abrasivity sodium bicarbonate air polishing. For patients with widespread sensitivity or exposed root surfaces, this approach often improves appointment tolerance without compromising clinical efficacy.

Periodontal Maintenance Patients

Patients with a history of periodontal disease undergoing active maintenance require effective subgingival biofilm removal. With subgingival nozzle attachments, erythritol and glycine powders can safely address biofilm in pockets up to approximately 5 mm. The low abrasivity of these formulations protects soft tissue while effectively disrupting biofilm. Clinicians using glycine or erythritol air polishing for subgingival application report good patient tolerance and clinical attachment gain in published trials, making this population well-suited for air-polishing protocols.

Patients Requiring Special Consideration

Heavy Calculus Deposits

Air polishing alone cannot remove calculus. Patients with heavy supragingival or subgingival calculus require initial calculus removal using ultrasonic instruments or hand instruments before air polishing can be effectively applied. Attempting air polishing without prior calculus removal wastes time and frustrates both clinician and patient. A practical sequence: ultrasonic or hand debridement first, then air polishing to remove remaining biofilm and polish. This combination approach addresses the full clinical presentation.

Respiratory Conditions

Patients with asthma, chronic obstructive pulmonary disease (COPD), or other respiratory conditions require aerosol reduction. While air-polishing devices generate fewer aerosols than ultrasonic instruments when used properly, patients with underlying respiratory disease warrant extra precaution. Strategies include: using high-volume evacuation at chairside, limiting procedure duration, considering alternative non-aerosol methods (hand instruments), and consulting the patient's medical history. These patients are not categorically excluded from air polishing but need individualized risk assessment.

Sodium-Restricted Diets

Patients on strict sodium-restricted diets due to hypertension, renal disease, or heart failure should avoid sodium bicarbonate powder. A single prophylaxis appointment with sodium bicarbonate generates measurable sodium absorption; for patients with sodium-sensitive conditions, this becomes clinically relevant. For these patients, specify erythritol or glycine powder, which contain negligible sodium and pose no dietary conflict.

Active Respiratory Tract Infection

Patients with active communicable respiratory illness (confirmed influenza, COVID-19, tuberculosis) should not receive elective air polishing due to aerosol generation. Postpone routine prophylaxis until the patient is no longer infectious. Non-elective procedures requiring care can proceed with maximum aerosol precautions, but routine prophylaxis can wait.

Powder Selection for Specific Patient Scenarios

Decision Framework

Matching the correct powder to the patient's clinical presentation optimizes outcomes:

• Healthy enamel with moderate to heavy extrinsic stain: Sodium bicarbonate or glycine. Sodium bicarbonate is more aggressive on stain but higher abrasivity. Glycine balances efficacy with gentleness.
• Implants or tooth-colored restorations: Erythritol or glycine only. Avoid sodium bicarbonate due to potential surface damage.
• Subgingival biofilm in pockets ≤5 mm: Erythritol or glycine with subgingival nozzle. Sodium bicarbonate is not indicated subgingivally.
• Sensitive teeth or exposed root surfaces: Erythritol (lowest abrasivity, smallest particle size) is preferred. Second choice: glycine. Avoid sodium bicarbonate.
• Sodium-restricted patient: Erythritol or glycine. Sodium bicarbonate is contraindicated.
• Orthodontic appliances: Glycine or erythritol. Both are safe on composite brackets and ceramic materials.

Air Polishing in Practice: Integration Strategy

Expanding air-polishing use doesn't require eliminating other prophylaxis methods. Most effective practices integrate air polishing strategically: routine maintenance and recall patients receive air polishing as first-line prophylaxis; patients with heavy calculus receive ultrasonic or hand debridement followed by air polishing; high-anxiety or sensitive patients are scheduled for air-polishing appointments specifically because the method aligns with their tolerance. Over time, as clinicians develop proficiency and patient feedback accumulates, air polishing often becomes the default approach for the majority of patients, with hand instruments and ultrasonic scaling reserved for specific indications (calculus, burnished stain, specific clinical circumstances).

Conclusion

Air polishing has moved from a niche stain-removal tool to a mainstream biofilm management approach suitable for diverse patient populations. Ideal candidates include routine maintenance patients, implant patients, orthodontic patients, patients with sensitivity, and periodontal maintenance patients. The shift toward low-abrasivity powders (glycine and erythritol) has expanded the eligible patient pool significantly beyond what was possible with sodium bicarbonate alone. Strategic powder selection—matching formulation to patient characteristics and clinical presentation—ensures optimal outcomes. While some patients (those with heavy calculus, certain respiratory conditions, or acute communicable disease) require special consideration or alternative methods, the vast majority of dental patients benefit from air-polishing prophylaxis. As clinical evidence continues to accumulate and practitioner familiarity increases, air polishing is likely to become the default prophylaxis approach in evidence-based practices.
