Dental hygiene routines are far from limited to toothbrushing alone. A comprehensive clean involves multiple layers, and it is becoming well understood that interdental brushing is a vital component of this. Of course, a complete routine might include mouth rinses, tongue cleaning, and/or the use of fluoride-based products, but interdental brushing is widely evidenced to be one of the most crucial and unavoidable steps.[i]
When recommending interdental brushes to patients, several factors might be involved, specific to the individual. Selecting the right size, ergonomics, and other favourable factors can each make a significant difference to comfort and hence, compliance.
TANDEX for every patient
One remarkable choice is TANDEX, and its range of FLEXI interdental brushes. Delivering uncompromised comfort and performance, TANDEX have thought of everything in their design – guaranteeing an impressive clean. Intended to support everyday plaque control, FLEXI brushes are engineered to access the hardest to reach spots that conventional brushing alone simply cannot sufficiently clean.
As well as ensuring the clean is effective when using the FLEXI, TANDEX also ensures it is as comfortable as possible. The wire is plastic-coated to minimise the risk of abrasive damage – something that often occurs with other interdental brushes.[ii]
One size does not fit all
Between patients with natural dentition, restorations, implants, orthodontic appliances, and more, the range of FLEXI brushes from TANDEX have a size for everyone. The colour-coded collection offers 11 sizes, with variations for specific requirements including 4 additional variants in the FLEXI UltraSoft range.
Appropriate sizing is essential; using a brush that is too small will fail to make adequate contact with the tooth surfaces, leaving behind the plaque and omitting its purpose entirely. However, using a brush that is too thick can cause trauma to the tissue. Long-term, this couldlead to gingival recession.[iii]
TANDEX offers a range that is extensive enough to overcome these issues, ensuring that patients can trial different sizes – working their way up in size – and guarantee the best oral hygiene. The graduated sizing system of the FLEXI range encourages accurate selection and supports the continuum of excellent oral hygiene when leaving the dental practice.
Ergonomics encapsulated
TANDEX have created the FLEXI range with a design that surpasses all other interdental brushes on the market. Firstly, the unique non-slip rubber handle provides a consistently firm grip, even when fingers are wet.
When patients are adding something to their oral hygiene routines, ensuring it is simple and ergonomic can go a long way in turning the additions into long-term habits. The brushes improve ease of use further with the extendable handle that dual-serves as a protective cap. This, combined with the flexible handle material, makes it significantly easier for the bristles to reach into otherwise inaccessible interdental spaces.
A dream duo
Incorporating physical interdental brushing into oral hygiene routines is already an appropriate foundation and a step towards oral hygiene excellence. However, adding a complementary step can further enhance oral hygiene routines.One such step, specifically designed for the job by TANDEX, is the PREVENT Gel. Formulated with an effective combination of fluoride (900 ppm) and chlorhexidine (0.12%), enamel is strengthened and the extra antibacterial effect ensures a maximised clean.
Used in conjunction with FLEXI brushes, PREVENT Gel can be applied directly to the bristles before use, allowing the ingredients to target all the hardest-to-reach areas with precision. Together, TANDEX FLEXI interdental brushes and PREVENT Gel offer a considered, clinically aligned approach to interdental care — practical, targeted and designed to support long-term oral health.
A combination for all patients
With the sheer importance of interdental brushing – beyond other additions like mouth wash and string flossing – recommending the best fit and design for patients is essential. TANDEX offers comfort, deep-cleaning, and so much more with its FLEXI range, manufactured to suit everyone’s needs.
