Introduction
Many people feel a degree of apprehension ahead of a dental hygiene appointment — particularly those who have found traditional cleaning methods uncomfortable in the past. Whether it is sensitivity around the gum line, anxiety about metal instruments, or simply an uncertainty about what the process involves, these are entirely understandable concerns that dentists and hygienists hear regularly.
Airflow polishing is a modern dental hygiene technique that is increasingly used in London clinics as a gentler, more effective alternative to conventional cleaning methods. It uses a controlled stream of warm water, fine powder, and compressed air to remove plaque, staining, and biofilm — often with noticeably less discomfort than traditional scaling and polishing approaches.
This article explains how Airflow polishing works, who may benefit from it, what patients can typically expect during the procedure, and when a professional hygiene assessment may be the most appropriate next step. Understanding your options is an important part of feeling confident and informed about your dental care.
Featured Snippet: What Is Airflow Polishing and How Does It Work?
Airflow polishing is a dental hygiene treatment that uses a pressurised mixture of warm water, compressed air, and fine powder particles to gently remove plaque, surface stains, and biofilm from teeth and along the gum line. It is considered by many patients to feel more comfortable than traditional polishing and is suitable for a range of oral health needs, subject to clinical assessment.
What Is Airflow Polishing?
Airflow polishing — sometimes referred to as guided biofilm therapy when used as part of a structured clinical protocol — is a minimally invasive hygiene technique developed to make professional tooth cleaning more thorough and more comfortable for patients.
The system works by projecting a carefully controlled jet of warm water, fine powder (typically sodium bicarbonate, erythritol, or glycine), and compressed air directly onto the tooth surfaces. This combination effectively dislodges and removes the soft bacterial deposits, surface stains, and biofilm that accumulate on teeth over time — including in areas that are difficult to reach with conventional instruments alone.
One of the most notable aspects of Airflow treatment is that it is generally considered less abrasive on tooth enamel and gum tissue compared to traditional rotary rubber cup polishing. The fine powder particles do the work without the mechanical friction associated with older techniques, which is why many patients describe the experience as significantly more comfortable.
Airflow technology has evolved considerably in recent years. Modern systems allow the clinician to adjust water temperature and powder pressure according to individual patient needs, which helps make the treatment well-tolerated even for those with sensitive teeth or gum tissue.
How Does Airflow Polishing Differ from Traditional Cleaning?
To appreciate the benefits of Airflow polishing, it helps to understand what traditional dental cleaning typically involves. Conventional hygiene appointments often include ultrasonic scaling to break up hardened tartar (calculus), followed by polishing with a rotating rubber cup and a mildly abrasive paste. While effective, some patients find this combination uncomfortable — particularly if their gums are inflamed, or if they experience dental sensitivity.
Airflow polishing addresses some of these concerns in several ways:
- Reduced contact with tooth surfaces: Because the treatment relies on a directed air and water stream rather than direct instrument contact, many patients report less pressure and discomfort during the procedure.
- Consistent access across tooth surfaces: The jet can reach interproximal spaces (between the teeth), below the gum margin, and around orthodontic brackets or implant surfaces more efficiently than a rotating cup.
- No abrasive paste required: Modern Airflow powders are designed to be gentle on enamel, avoiding the micro-scratching that can occasionally occur with older polishing pastes.
- Effective biofilm disruption: The system is particularly effective at removing the soft bacterial biofilm that contributes to gum disease and tooth decay, even before it has hardened into calculus.
That said, Airflow polishing is not always used in isolation. In cases where significant calculus build-up is present, ultrasonic scaling may still be required as part of the overall treatment plan. Your dental hygienist will assess your needs during your appointment and tailor the approach accordingly.
The Clinical Science Behind Airflow Polishing
Understanding why dental biofilm matters can help explain why techniques like Airflow polishing are clinically significant.
Dental plaque is a complex community of bacteria that forms a sticky film on tooth surfaces. When allowed to accumulate undisturbed, this biofilm matures and hardens into calculus — a mineralised deposit that cannot be removed by brushing alone. Both plaque and calculus are primary risk factors for gingivitis (gum inflammation) and periodontitis (deeper gum disease), as well as for tooth decay.
Airflow polishing is particularly effective at removing soft biofilm in its early stages — before it has had the opportunity to mineralise. The erythritol and glycine powders used in modern Airflow systems are specifically chosen because they are fine enough to be effective without causing trauma to enamel or the delicate tissue of the gum sulcus (the shallow groove between the tooth and gum).
Some clinical evidence supports the use of Airflow as part of guided biofilm therapy protocols, suggesting it may be more effective at removing supragingival (above the gum line) and subgingival (below the gum line) biofilm compared to conventional polishing in certain presentations. However, as with all dental treatments, individual results depend on clinical factors that a qualified hygienist or dentist will assess during examination.

Who May Benefit from Airflow Polishing?
Airflow polishing may be suitable for a wide range of patients, though individual clinical assessment is always necessary to determine the most appropriate treatment approach. Patients who may particularly benefit include:
Those with surface staining: Airflow is highly effective at removing extrinsic staining caused by tea, coffee, red wine, or tobacco. Many patients notice a visible improvement in tooth brightness following treatment — though it is important to note that Airflow polishing removes surface stains rather than altering the underlying shade of the tooth.
Patients with sensitive teeth or gums: Because the treatment involves less direct mechanical contact with tooth surfaces, it is often better tolerated by those with gum sensitivity or tooth sensitivity around the cervical (neck) area of the teeth.
Those with orthodontic appliances: Airflow is well-suited to cleaning around fixed braces, retainers, and other orthodontic appliances, where conventional instruments may struggle to access.
Patients with dental implants: Conventional metal instruments should generally not be used on implant surfaces. Airflow with appropriate powder is considered a safer option for maintaining hygiene around implant restorations.
Adults managing early gum disease: Airflow can form part of a structured approach to managing gingivitis, helping to reduce bacterial load in a more comfortable way than some traditional methods.
Older patients or those with complex dental needs: Patients who find conventional treatment uncomfortable due to age-related sensitivity, dry mouth (xerostomia), or other health considerations may find Airflow a more manageable experience.
Suitability for any treatment should always be confirmed through a clinical assessment with a qualified dental professional.
What to Expect During an Airflow Polishing Appointment
For many patients, knowing what to expect during a dental appointment helps reduce anxiety considerably. A typical Airflow polishing session at a dental hygiene clinic in London may include the following stages:
1. Initial assessment: Your hygienist will examine your teeth and gums to assess the level of plaque, calculus, and staining present, and to determine the most appropriate approach for your individual needs.
2. Calculus removal (if required): If hardened tartar is present, ultrasonic or hand scaling may be carried out before or alongside Airflow treatment to ensure thorough results.
3. Airflow application: The hygienist will direct the Airflow handpiece across your tooth surfaces, including the gum margins and between teeth. Most patients describe the sensation as a fine mist or spray — noticeably gentler than rotary polishing.
4. Irrigation and review: The mouth will be rinsed, and your hygienist will review the results, offering tailored advice on home oral hygiene to support the outcome of the treatment.
The appointment length will vary depending on individual needs, but many hygiene visits incorporating Airflow last between 45 and 60 minutes.
When Professional Dental Assessment May Be Appropriate
If you have noticed any of the following, it may be appropriate to arrange a professional dental or hygiene assessment:
- Bleeding gums when brushing or flossing, which can be an early indicator of gingivitis
- Persistent bad breath that does not resolve with improved oral hygiene
- Visible staining on teeth that concerns you
- Sensitivity around the gum line that has recently developed or worsened
- Visible build-up of calculus, particularly behind the lower front teeth or around the upper back teeth
- Discomfort during previous hygiene appointments that has put you off attending regularly
It is worth emphasising that none of these symptoms necessarily indicate a serious condition. Many are very common and respond well to professional hygiene care. However, they are worth discussing with a dental professional who can assess your individual situation accurately.
If you have specific concerns about gum health or are unsure whether Airflow polishing is appropriate for you, speaking with a qualified dental hygienist is always a sensible first step. You can explore hygiene appointments available in London to find a time that suits you.

Prevention and Oral Health Advice
Professional hygiene appointments, including Airflow polishing, work best as part of a consistent approach to oral health. Here are some practical steps that support good dental hygiene between appointments:
Brush twice daily: Use a fluoride toothpaste and brush for at least two minutes, morning and last thing at night. Electric toothbrushes are often recommended as they provide more consistent plaque removal than manual brushing for many people.
Clean between your teeth daily: Interdental brushes, floss, or a water flosser can reach the areas that a toothbrush cannot access. This is particularly important for gum health, as the spaces between teeth are where gum disease most commonly begins.
Moderate staining foods and drinks: If reducing surface staining is a priority, it may help to moderate consumption of tea, coffee, red wine, and dark-coloured sauces. Using a straw for cold beverages and rinsing with water after consuming staining foods can help to some degree.
Stay hydrated: Adequate hydration helps maintain saliva flow, which plays an important role in naturally washing the mouth, neutralising acids, and protecting tooth enamel.
Attend regular hygiene appointments: The frequency that is right for you will depend on your individual gum health and susceptibility to plaque build-up. Your hygienist can advise on an appropriate recall interval.
Consider your diet: Limiting frequent intake of sugary or acidic foods and drinks reduces the risk of enamel erosion and tooth decay, supporting the long-term health of your teeth.
For personalised dietary and hygiene advice, a consultation with a London dental hygienist can provide tailored guidance based on your specific oral health profile.

Frequently Asked Questions
Is Airflow polishing suitable for sensitive teeth?
Airflow polishing is often well-tolerated by patients with tooth sensitivity, as it involves less direct mechanical contact with tooth surfaces than traditional rotary polishing. The water temperature can also be adjusted to improve comfort. However, suitability depends on the nature and degree of sensitivity, as well as any underlying causes. Your hygienist will assess your individual situation before recommending the most appropriate approach for your appointment.
How long does Airflow polishing take?
The duration of an Airflow polishing session varies depending on individual needs. Most hygiene appointments that incorporate Airflow polishing last between 45 and 60 minutes, though this may be shorter or longer depending on the amount of plaque, calculus, or staining present. Your hygienist will give you a more accurate estimate once they have assessed your teeth and gums at the start of your appointment.
Will Airflow polishing whiten my teeth?
Airflow polishing is effective at removing extrinsic surface staining caused by food, drink, and tobacco. This can result in a noticeably brighter appearance for some patients. However, it is important to understand that Airflow polishing removes surface deposits rather than altering the natural shade of the underlying tooth structure. It is not a tooth whitening treatment. For advice on cosmetic whitening options, a separate consultation with a dental professional would be appropriate.
How often should I have Airflow polishing done?
The recommended frequency of professional hygiene appointments varies from person to person. Some individuals with a higher susceptibility to plaque build-up or gum disease may benefit from appointments every three to four months, while others with good oral health may find six-monthly visits sufficient. Your dental hygienist will assess your gum health and oral hygiene needs and advise you on an appropriate recall interval tailored to your circumstances.
Can Airflow polishing be used around dental implants?
Yes — Airflow polishing with appropriate powder is generally considered a safe and effective option for cleaning around dental implants. Conventional metal instruments are typically avoided on implant surfaces to prevent damage to the restoration or the implant itself. Airflow provides a gentler alternative that can effectively remove biofilm from around the implant and supporting gum tissue. Your hygienist will always confirm the most appropriate approach based on the type and condition of your implant.
Does Airflow polishing hurt?
Most patients describe Airflow polishing as comfortable — often more so than traditional cleaning methods. The sensation is typically described as a fine mist or gentle spray. Some patients may experience mild sensitivity if gum inflammation is present, though the warm water temperature used in modern systems helps to minimise discomfort. If you have concerns about comfort or anxiety about dental appointments, it is always worth discussing this with your hygienist before the session begins, so adjustments can be made where possible.
Conclusion
Airflow polishing represents a meaningful development in modern dental hygiene care, offering a gentler and often more thorough approach to removing plaque, biofilm, and surface staining from teeth. For patients who have previously found hygiene appointments uncomfortable — or who have avoided them altogether — understanding that alternatives exist is an important first step.
As with all dental treatments, airflow polishing is most effective when it is tailored to individual patient needs and delivered as part of a consistent approach to oral health. Good home hygiene habits, appropriate nutrition, and regular professional appointments all play a role in maintaining healthy teeth and gums over the long term.
If you have concerns about staining, gum health, sensitivity, or simply want to explore a more comfortable hygiene experience, speaking with a qualified dental hygienist is a straightforward and constructive next step.
