Braces can triple plaque buildup, study finds

New research highlights how orthodontic treatment can sharply raise plaque and cavity risk, with white spot lesions appearing as soon as four weeks after braces go on. The findings help explain why interdental cleaning is often the first hygiene habit patients drop during treatment.

Why it matters: - Orthodontic treatment can make daily cleaning much harder at the exact time patients need more rigorous hygiene. - Higher plaque levels raise the risk of white spot lesions and dental caries during braces treatment. - The findings reinforce the need for interdental tools designed for people with brackets, wires and other appliance hardware.

What happened: - A study in the American Journal of Orthodontics and Dentofacial Orthopedics found plaque coverage in orthodontic patients was 2 to 3 times higher than in adults who already form plaque heavily and wear no appliances. - A separate study in the same journal found 72.9% of patients developed at least 1 new white spot lesion during treatment. - A large-scale review in BMC Oral Health identified orthodontic treatment as a recognized risk factor for dental caries. - Tonochi, a San Francisco oral care company focused on interdental health, issued the release.

The details: - Brackets, archwires and ligatures create surfaces and crevices that toothbrushes cannot fully reach. - White spot lesions, the first visible sign of enamel demineralization, can appear within 4 weeks of appliance placement. - Threading floss under an archwire can turn a 2-minute task into a 10-minute routine. - Randomized trial data on orthodontic hygiene show interdental cleaning is the step most often abandoned mid-treatment. - Only about 1/3 of adults clean between their teeth daily under ordinary circumstances. - That rate falls further for patients wearing orthodontic hardware. - Orthodontists increasingly recommend threading aids, interdental brushes, floss picks and soft picks as practical alternatives. - Tonochi develops interdental tools for patients with braces, bridges and implants. - Tonochi products are available at tonochi.com and on Amazon. - Tonochi also links to its social pages on LinkedIn, Instagram, Facebook, YouTube, TikTok and Pinterest.

Between the lines: - The release argues that the problem is not a lack of motivation alone, but a mismatch between standard oral care products and the reality of orthodontic appliances. - Teenagers may be especially vulnerable because interdental cleaning requires more patience and dexterity than many patients sustain over months of treatment. - The practical takeaway is a shift toward tools that fit the mouth patients actually have, rather than tools that assume unobstructed teeth.

What's next: - Orthodontic patients are likely to see continued emphasis on interdental cleaning aids as part of routine care. - The market for braces-friendly oral hygiene products may keep growing as clinicians try to reduce plaque buildup and enamel damage during treatment. - Tonochi is positioning its product line around that need, with a focus on braces, bridges and implants.

The bottom line: - Braces can improve alignment, but they also create a real cleaning problem that can quickly lead to plaque buildup and cavity risk if patients skip interdental care.
