Between the teeth: Beyond the disease

Dental hygienists play a crucial role in both preventing and slowing the progression of periodontal disease. This topic is particularly relevant as maintaining disease stability after non-surgical periodontal therapy largely depends on effective oral hygiene practices. Identifying the most effective interdental tools is essential for optimizing patient outcomes and supporting long-term periodontal health.

In dental hygiene school, we are taught a wide range of interdental aids such as floss, interdental brushes, water flossers, and many more tools designed to reach areas that are more complex and susceptible to biofilm adherence. It has been proven that inflammation biomarkers causing periodontitis have been widely found interdentally, recolonizing quickly after non-surgical periodontal treatment (NSPT) confirming the importance of interdental cleaning.¹ Periodontal stability depends heavily on the individualized and thorough at-home care; having the right interdental regimen can make a difference in the long-term maintenance or recurrence of disease. This applies not only to periodontitis but also to reversible signs of gingivitis. 

This article aims to examine the most effective evidence-based interdental cleaning methods for periodontally involved patients and explores the growing influence of social media on consumer choices for interdental cleaning. Popular interdental products trending online and patient claims regarding plaque removal, inflammation reduction, bone stimulation, and long‑term periodontal support. 

Why interdental care matters

Following NSPT, patients often experience reduced pocket depths, smoother root surfaces, reduced gingival inflammation, and bleeding. These improvements can quickly return to active disease without consistent home care. Interdental cleaning is essential, as it consists of 40% of tooth surfaces, and if left untouched, it leaves a breeding ground for plaque and bacteria.² Effective interdental cleaning is a critical component of periodontal disease healing and management. Biofilm accumulation between teeth is a primary contributor to inflammation, bone loss, attachment loss, and disease progression.² Without proper interdental cleaning and removing plaque and biofilm from areas that toothbrushing alone cannot reach and could contribute to rapid disease progression.  

Evidence-based interdental aids  

A thorough, individualized oral-care regimen for interdental cleaning is essential for maintaining periodontal health, particularly following NSPT when patients benefit from reduced pocket depths, biofilm disruption from root surfaces, and decreased inflammation. Selecting the right interdental aids is important for maintaining long-term periodontal stability.  

Gold-standard string floss can be less effective in open embrasure spaces; it is still valuable for tight contacts and areas where interdental brushes cannot fit.³ Interdental brushes are ideal for patients with open embrasure spaces, as their bristles can adapt closely to tooth anatomy.² Water flossers are particularly beneficial for patients with dexterity challenges and deeper pockets.⁴ Research demonstrates a significant reduction in bleeding, inflammation, and disruption of biofilm when used as an adjunctive tool, though water flossers are not considered a substitute for string floss or interdental brushes.⁴ End tuft brushes also serve as useful adjuncts to brushing and interdental cleaning, offering access to difficult-to-reach areas such as the distal of terminal molars, severe crowding, limited opening, or reduced dexterity.⁵ 

Social media influence 

While many interdental aids are supported by years of research, social media has become a powerful window into how people approach everyday routines, from cleaning their homes to choosing hair products, supplements, and even oral hygiene tools. Interdental cleaning aids are no exception.

A growing number of users share videos featuring traditional black floss, demonstrating various plaque‑removal techniques and emphasizing the visual contrast between the dark floss and the white or yellow plaque it collects. Some claim it removes more plaque than white floss simply because the debris is easier to see. Several dental hygienists have noted that black floss can be a helpful tool for visual learners, allowing patients to clearly see what they are removing.

For some individuals, this visual feedback can serve as a motivating factor to continue flossing consistently. Black floss has become a trending product in the market and may be useful for providers and patients during chairside oral hygiene instruction. However, there is currently a lack of scientific, evidence‑based research evaluating its true efficacy. 

Non-evidence-based aids

Beyond black floss, other products circulating on social media, particularly at‑home ultrasonic devices, are being heavily advertised with claims such as “remove calculus at home” and “deep clean without the dentist."

Many of these tools lack warning signs and are marketed as safe for anyone to use, often implying they can replace “expensive dental visits”. In reality, the only warning most of these kits provide relates to battery safety, with no mention of clinical risks, proper technique, or the lack of ADA approval. These devices often receive thousands of views, comments, and purchases at an alarming rate.

A typical kit includes a “tartar” scraper, dental probe, oral mirror, storage box, and interchangeable cleaning heads, usually a flat tip and a pointed tip marketed for “deeper cleaning.” One kit even claimed the device would automatically stop working when it touched soft tissue such as the gums. Many advertise ultrasonic power levels around 300W or higher and claim to remove calculus, plaque, stains, and dark crevice lines. Although the design resembles an electric toothbrush, these devices instead feature a sharp scaler‑like tip and multiple operating modes.

Most do not produce water but are advertised as vibrating at rates up to 11,000 times per minute. As dental hygienists, we are trained extensively in the safe and effective use of ultrasonic scalers, including the potential dangers when they are used improperly. DIY dental treatment can easily lead to misuse and cause significant harm to the periodontium, including painful trauma, gum recession, enamel defects that contribute to sensitivity, and possible soft‑tissue injury with risks of infection.

Yet many of these products circulating on TikTok are only one click away from ending up in a patient’s hands.  Dental hygienists thrive when patients take initiative and stay engaged in their oral hygiene, especially when infection is present, although patient education must prioritize safety, accuracy, and evidence‑based recommendations. Studying these online trends can help dental professionals better understand patient preferences and guide education not only on proper interdental cleaning aids but also on how to build a safe, effective at‑home dental care routine grounded in science rather than marketing. 

Conclusion

Evidence-based interdental aids such as floss, interdental brushes, water flossers, and end-tuft brushes continue to be the foundation of periodontal care, as supported by the American Dental Association on interdental cleaning.⁶ At the same time, with the rapid rise and engagement of social media, a new layer of complexity and possibly confusion as different products are continually marketed, with some harmless and potentially motivating, like black floss, and others far more concerning, such as DIY teeth scaler kits with misleading claims.

These trends can confuse patients between safe home care and potentially harmful at-home treatments. As clinicians, staying open-minded and informed about these online influences allows us to better understand the questions patients may bring into the operatory and address misinformation in a safe, judgment-free environment to ensure the safety of our patients.
