Beyond Brushing and Flossing: Alternative Techniques for Optimal Oral Health

When it comes to oral hygiene, most people focus on brushing, flossing, and regular dental checkups. While these habits are foundational and absolutely necessary, they don’t always address the full picture of oral health. In recent years, there has been growing interest in complementary practices that support the oral microbiome, reduce inflammation, and promote overall systemic wellness. For patients who feel they are “doing everything right” yet still struggle with cavities, gum inflammation, dry mouth, or bad breath, these alternative techniques may offer meaningful support when used thoughtfully alongside traditional care.

Tongue Scraping

One simple yet powerful adjunct is tongue scraping. The tongue harbors a significant amount of bacteria, dead cells, and debris that can contribute to bad breath and microbial imbalance. Gently scraping the tongue with a metal or plastic tool can help reduce volatile sulfur compounds associated with halitosis and may lower levels of bacteria linked to cavities and gum disease. Research has also shown that incorporating tongue scraping into a hygiene routine may reduce inflammatory markers in patients with gingivitis. When practiced gently—about once a week—it can improve taste perception and complement brushing and flossing without irritating the tongue.

Oil Pulling

Another widely discussed alternative practice is oil pulling, an Ayurvedic technique that involves swishing an edible oil such as coconut, sesame, or sunflower oil in the mouth for several minutes before spitting it out. Emerging research suggests oil pulling may temporarily reduce bacterial load and plaque levels in the mouth, particularly when coconut oil is used. While the evidence continues to evolve, oil pulling appears to be a helpful adjunct for some individuals when done gently and consistently. It should never replace brushing or flossing, and the oil should always be spit out rather than swallowed.

Mouth Taping (Promoting Nasal Breathing)

Breathing patterns also play a surprising role in oral health. Mouth taping, which encourages nasal breathing during sleep, has gained attention for its potential to reduce dry mouth and support healthy saliva flow. Saliva is essential for buffering acids, supporting remineralization, and maintaining microbial balance. While some people report improved sleep quality and reduced snoring with mouth taping, it is not appropriate for everyone. Individuals with nasal obstruction, sleep apnea, or other breathing concerns should avoid this practice or consult a healthcare provider before trying it. If used, only skin-safe tape designed for the lips should be applied, and breathing should never feel restricted.

Nutrition/Supplements for Oral Microbiome Support

Nutrition is another critical yet often overlooked component of oral health. What we eat directly influences the oral microbiome. Diets high in refined carbohydrates and sugars feed acid-producing bacteria, while whole-food, nutrient-dense diets support beneficial microbes and tissue health. Limiting fermentable sugars, prioritizing leafy greens rich in nitrates, consuming arginine-containing foods like nuts and legumes, and incorporating anti-inflammatory fats such as omega-3s can all contribute to healthier gums and teeth. Adequate hydration is equally important, as saliva plays a central role in protecting enamel and maintaining a balanced oral environment.

Activated Charcoal (Used Judiciously)

Activated charcoal has also become popular in oral care products, though it should be used cautiously. Due to its highly adsorptive nature, charcoal may bind certain bacteria and toxins and help remove surface stains from teeth. Some studies suggest it may raise oral pH, making conditions less favorable for acid-producing bacteria. However, charcoal can be abrasive, and excessive or frequent use may contribute to enamel wear or surface roughness—especially on restorations. For most people, charcoal is best used sparingly, such as once weekly, while monitoring for sensitivity.

Xylitol Rinses/Gum/Mints

Xylitol is another well-studied adjunct that can support oral health when used in rinses, gums, or mints. Unlike sugar, xylitol cannot be metabolized by many cavity-causing bacteria, effectively starving them of their energy source. It helps raise oral pH, promotes saliva production, and supports a less acidic environment in the mouth. Because of its strong evidence base, xylitol is commonly recommended by integrative dental providers as part of a caries-prevention strategy, especially after meals.

Red Light / Photobiomodulation Therapy

More advanced therapies are also gaining attention, including red light or photobiomodulation therapy. Low-level red or near-infrared light applied to oral tissues may help reduce inflammation, accelerate healing, and support tissue regeneration following dental procedures. Emerging research suggests it may also reduce inflammatory markers around dental implants. These therapies should be used with devices designed specifically for photobiomodulation and ideally under professional guidance, as consistency and proper application are key to seeing benefits.

Oral Probiotics

Oral probiotics represent another exciting area of research. Specific strains, such as Streptococcus salivarius K12 or M18, are formulated to colonize the mouth and compete with harmful bacteria. Studies suggest these probiotics may help reduce bad breath, suppress cavity-causing microbes, and support immune balance within the oral cavity. For best results, probiotics should be taken at times when the mouth is least disrupted—often before bed—and not immediately after using strong antiseptic rinses that could eliminate beneficial bacteria.

Ozonated Glycerine

Ozonated glycerine is a lesser-known but powerful adjunct used in integrative dentistry. By infusing glycerine with ozone, a stable antimicrobial rinse or gel can be created that targets harmful bacteria and biofilm while remaining gentle on tissues. This therapy may be helpful in managing early decay, gum inflammation, or supporting healing after dental treatment. Because ozone is potent, it should be used thoughtfully and under professional guidance to avoid disrupting the beneficial microbial balance.

Integrating These Techniques Safely

When exploring alternative oral-health practices, a gradual and personalized approach is key. Introducing one or two techniques at a time allows you to observe how your body responds while continuing to prioritize the fundamentals—brushing, flossing, and routine dental visits. These tools are meant to complement, not replace, standard care, and guidance from an integrative dentist or hygienist can help ensure they’re appropriate for your unique oral environment.

Integrative dentistry views the mouth as a dynamic ecosystem influenced by the oral microbiome, saliva, nutrition, and even breathing patterns. Because every mouth is different, not every approach will be beneficial for everyone. For patients seeking a more data-driven strategy, oral salivary microbiome testing can offer valuable insight. Testing before and after introducing new techniques helps identify what’s truly supporting your oral health, allowing you to make informed, personalized decisions that benefit both your smile and overall wellness.
