Our chews combine three ingredients: hydroxyapatite (the mineral teeth are made of), xylitol (a sweetener that mouth bacteria cannot feed on) and an oral probiotic complex. Below is a summary of the key findings from published studies on these ingredients and on the mouth's bacteria, with the full reference beneath each one, as indexed on PubMed. These are findings on the ingredients or on similar products and formats, not trials of our product.
A 2022 randomized clinical trial in physically active adults followed two home oral care routines built on biomimetic hydroxyapatite, a toothpaste with a mouthwash or the toothpaste alone. Over the follow-up period the researchers tracked plaque and bleeding scores, along with sensitivity and erosive wear indexes. They reported a progressive reduction in every index from the start of the study onward, with no difference between the two routines.

A 2025 randomized clinical trial compared two hydroxyapatite-based toothpastes in people aged 6 to 18 over six months, measuring enamel, plaque, bleeding and sensitivity indexes. The group using the zinc carbonate hydroxyapatite toothpaste showed a significant reduction in plaque levels after three months of use (the comparison group saw one after one month). The authors also noted that the bleeding and sensitivity scores did not differ between the groups, and that additional measures may be needed for gum comfort and sensitivity.

In a 2024 double-blind randomized trial in adults, a toothpaste containing zinc citrate, hydroxyapatite and potassium citrate, alongside fluoride, was compared with a fluoride-only toothpaste for four weeks. Self-reported tooth sensitivity was lower in the group using the hydroxyapatite-containing toothpaste, and salivary counts of a common mouth bacterium fell more in that group. The two toothpastes did not differ on plaque or gum scores. This is a finding on a multi-ingredient toothpaste, not on hydroxyapatite alone.

In a randomised, placebo-controlled trial of 154 participants, those who chewed xylitol gum for three weeks showed lower gingival and plaque index scores than at the start of the study. Their saliva also showed lower levels of three inflammation markers, and counts of a common mouth bacterium fell about fivefold. The authors described xylitol as possibly playing a favourable role in maintaining oral health, while noting that the finding warrants further confirmation.

A double-blind randomized trial in 80 students compared gum containing xylitol with gum containing sorbitol and maltitol, three times a day for 30 days. By day 30 the xylitol group showed a significantly lower count of mutans streptococci in saliva than the comparison group. The researchers concluded that xylitol gum may interfere with the make-up of these bacteria after continuous use. They found no significant difference between the two gums in plaque or gingival scores.
Reference: Oza S, et al. Journal of International Society of Preventive and Community Dentistry. 2018. PMID: 30123770. DOI: 10.4103/jispcd.JISPCD_54_18.
A 2021 randomized controlled trial in 96 older adults compared a daily probiotic yogurt with xylitol chewing gum taken three times a day. Both groups showed a statistically significant reduction in the level of mutans streptococci in saliva and plaque across the follow-up periods, a significant rise in salivary pH, and a significant reduction in bacterial adherence. The authors concluded that probiotic yogurt was an effective antibacterial agent against salivary and plaque bacteria in older patients.

A randomized, double-blind, placebo-controlled trial in 92 healthy adults with bad breath tested a probiotic tablet taken once a day for eight weeks. By week four, organoleptic (breath-smell) scores and volatile sulfur compound levels had significantly decreased in the probiotic group, and bad breath improvement scores were significantly reduced by week eight. All participants had a dental cleaning first. No safety issues were seen, and the authors concluded the tablets could be a safe and useful oral care product for controlling bad breath.
Reference: Lee DS, Lee SA, et al. Journal of Medicinal Food. 2020. PMID: 32379992. DOI: 10.1089/jmf.2019.4603.
A double-blind, placebo-controlled crossover trial gave patients with oral malodor probiotic lactobacilli tablets or placebo tablets over 14-day periods. Volatile sulfur compound levels were significantly lower in the probiotic period than in the placebo period, and so were levels of total bacteria and of one specific bacterium. Breath-smell scores fell in both periods, with no difference between them. The authors concluded that daily oral consumption of tablets containing probiotic lactobacilli could help to control oral malodor and malodor-related factors.

Twenty-five healthy young adults with self-reported morning bad breath completed a randomized, double-blind, placebo-controlled crossover trial of probiotic chewing gum, one in the morning and one in the evening for 14 days. After 14 days the breath-smell scores were significantly lower in the probiotic group than in the placebo group. Sulfur compound readings did not differ between the groups, so the authors suggested the probiotic gum may affect bacteria that produce other odour compounds. No adverse effects were recorded.

A 2025 systematic review and meta-analysis pooled randomized controlled trials of toothpastes containing lactic acid bacteria (probiotic, prebiotic, synbiotic or postbiotic agents). It reported significant plaque reduction at three months and improved gum-bleeding scores, with mouth bacteria levels reduced across several studies. The authors cautioned that the studies varied a great deal, which limits how precisely the effect can be estimated, and that longer use appeared necessary for some outcomes.

A 2025 review in the Journal of Oral Microbiology summarised the evidence on the oral microbiome and ageing. It found that the make-up of the oral microbiome changes with age, shaped by factors such as diet, oral hygiene and immune function, and that the microbiome is a promising target for strategies aimed at healthy ageing. The authors noted that interventions such as probiotics and dietary changes show promise, and that more research is needed on how the oral bacteria work.

Our Oral Health Chews bring together hydroxyapatite, xylitol and an oral probiotic complex in a strawberry chewable. Published studies on hydroxyapatite oral care describe falling plaque scores and less tooth sensitivity. Studies on xylitol describe lower plaque and gum scores and shifts in the mouth's bacteria. Trials of probiotic tablets and gum describe fresher breath scores. Reviews describe a balanced mouth microbiome as a promising focus for healthy ageing. These are findings on the ingredients or on similar products, not trials of our chews, and some studies found no difference on some measures. Take 1 chewable tablet daily, chewed slowly and ideally after brushing. Xylitol is toxic to dogs: keep out of reach of pets. Consult a healthcare professional first if you are pregnant or nursing, under 18, taking medication or have a pre-existing condition.

Oral Health Chews bring hydroxyapatite, the mineral your teeth are naturally made of, to your teeth and gumline in a slow-dissolving strawberry chewable.
Unlike toothpaste, which is on your teeth for a couple of minutes and then rinsed away, a chewable stays in your mouth longer and gives that mineral more time with your teeth.
Xylitol adds a pleasant sweetness that the bacteria which feed on sugar cannot use, while the oral probiotic complex supports a healthy balance of friendly bacteria in the mouth.
Together they are designed to support strong-feeling teeth, comfortable gums, fresher breath and less plaque build-up as part of your daily routine, alongside brushing, your usual water and everything your dentist and doctor already have you doing.
1 jar of Oral Health Chews contains 60 chewable tablets.
This will last you 60 days if you take the recommended 1 chewable tablet a day.
Consistency is key if you want to see the best results.

A dry mouth has crept up for years. But you were never taken seriously about it.
A check-up looks at every tooth and gumline — a look, a scrape, a polish — and the answer is “we’ll keep an eye on it.” Then you go home and wait until the next one. It’s not a daily plan. It’s a waiting game. And with a dry mouth, “drink more water” is often all you hear.
Rinses, sprays, gels, sensitivity toothpaste — they freshen the surface, never give teeth more time. Every rinse you spit out is a quick polish over a mouth that’s still asking for support.
Brushing lasts about two minutes and then it’s spat out. Your gumline gets little time with the one mineral your teeth are made of. And when your mouth still feels off? You’re told to drink more water.
It’s called hydroxyapatite — The mineral enamel is made of. And chances are, nobody ever mentioned it to you.
Here’s what’s actually happening around your teeth: sticky film that builds along the gumline settles onto your tooth surfaces. Once there, it leaves teeth rough and gums tender before your next brush gets a chance to reach it.
That build-up brings stale breath and that rough feeling. The tender gums. The sensitivity to cold that has you testing every cold sip before you swallow.
It’s not your age. It’s not bad luck. It’s not “just a dry mouth.” It’s a mouth needing balance.
The checks at your appointment? They’re looking for visible problems — chips, gaps, things you can see in a mirror. Everyday surface build-up doesn’t show up on those. So every result comes back “fine”.
Many people reach for xylitol as a sweet treat that sugar-feeding bacteria cannot use.
Your teeth are mostly one mineral, and a chewable gives it more time on teeth and gumline than brushing alone — that is the idea.
Our formula starts with a simple idea: hydroxyapatite — the mineral enamel is made of — supports strong-feeling teeth while friendly bacteria help balance your mouth.
Then add xylitol and friendly bacteria. Simple, sweet, and easy to chew.
That means one strawberry chewable instead of one more rinse or spray — same mouth, more time.
You’re keeping your water, your dentist and every prescription. You’re adding one small step your teeth have been missing.

Toothpaste and rinses are on your teeth for a couple of minutes and then spat out before the minerals and friendly bacteria can stay around. A chewable, chewed slowly, gives the mineral more time on your teeth and gumline. Nutrition Therapy’s Oral Health Chews pair hydroxyapatite, the mineral teeth are mostly made of, with xylitol and an oral probiotic complex, so they stay in contact longer, supporting the look and feel of strong teeth. That’s the core of what we call The Mineral Advantage.
Everyone’s mouth is different, but some people notice a fresher feel within the first few weeks. Changes in how your gums and teeth feel typically build over a couple of months of consistent use. Consistency matters. This isn’t a mint that freshens your breath for a few minutes. It’s a daily mouth-care habit.
Each chewable is strawberry flavored — most people enjoy it. Chew it slowly rather than swallowing it whole, so it spends time against your teeth and gumline. It typically feels pleasant. If you have a sensitive mouth, chew a little slower and take it after brushing.
We always recommend consulting your healthcare provider before adding any supplement to your routine, especially if you’re pregnant, nursing, or currently taking prescription medications. These chews are a dietary supplement and your provider should know everything you take. This does not replace anything prescribed to you. Xylitol is toxic to dogs: keep out of reach of pets.
No. Nutrition Therapy’s Oral Health Chews are not a toothpaste. They are a chewable dietary supplement with hydroxyapatite, xylitol, and an oral probiotic complex. Unlike a rinse or spray, a chewable offers longer contact with the teeth and gumline — while being gentle and pleasant in your mouth. Keep brushing as usual. No prescription required.
This is actually one of the most common stories we hear. Rinses and pastes have a short window on the teeth, because they are spat out within minutes. Oral Health Chews work differently. Their longer contact time gives the mineral and friendly bacteria more chance to support a balanced mouth and the look and feel of strong teeth and comfortable gums. Try them risk-free alongside your usual brushing.
Every jar of Nutrition Therapy’s Oral Health Chews is backed by a 60-day money back guarantee. If you don’t feel like it’s making a difference, you get your money back. We’re confident enough in what this formula does to take that risk off your shoulders entirely.
1 chewable daily. Chew it slowly rather than swallowing it whole, ideally after brushing, so the ingredients stay on clean teeth. Take consistently at the same time each day for best results.
Nutrition Therapy’s chews are designed as a simple daily habit alongside your brushing, not a replacement for it. If you are pregnant, nursing, or taking medication, speak with your healthcare provider first. You can keep taking it as part of a daily routine, and reassess based on how your mouth feels. Your healthcare provider can help you decide.
No. Nutrition Therapy’s Oral Health Chews are a dietary supplement and do not require a prescription.
