01 What is hydroxyapatite toothpaste?
Hydroxyapatite toothpaste uses a calcium phosphate mineral closely related to the mineral structure of enamel and dentin. Published studies have examined hydroxyapatite toothpastes for enamel remineralization, sensitivity, and caries endpoints. Results depend on the formula and study design, and those studies are not clinical trials of Klyyr One+.
02 Is Klyyr toothpaste fluoride-free?
Yes. One+ contains 0 ppm fluoride and a clearly disclosed 10% nano + micro hydroxyapatite blend. Published clinical evidence on hydroxyapatite toothpastes supports the ingredient category; those studies evaluated different formulas, not Klyyr.
03 How does hydroxyapatite compare with fluoride?
Hydroxyapatite is a fluoride-free alternative with growing clinical evidence. In one 18-month adult study, a 10% HAp toothpaste was non-inferior to 1450 ppm fluoride for the study's primary caries endpoint. That study tested a different formula, so it is ingredient-level evidence—not a Klyyr clinical result. Read the full hydroxyapatite vs fluoride comparison.
04 How does enamel-protecting toothpaste work?
It helps calcium and phosphate redeposit into early weak spots, leaves enamel more resistant to acid, or cleans without wearing enamel away. Fluoride has the most evidence. Hydroxyapatite, CPP-ACP, and NovaMin work through calcium and phosphate, and arginine through plaque pH, with smaller records. How each one works.
05 Which toothpaste ingredients help rebuild enamel?
Toothpaste can’t regrow lost enamel, but it can help minerals redeposit into early, weakened spots. Fluoride has the strongest evidence. Hydroxyapatite, CPP-ACP, and calcium sodium phosphosilicate are also studied. One+ contains 10% nano + micro hydroxyapatite; the studies we cite tested other formulas. See remineralizing toothpaste.
06 Why nano and micro hydroxyapatite?
Nano and micro are particle-size ranges of the same mineral. Published ingredient research examines how smaller particles interact with microscopic surface defects and dentinal tubules, while larger particles remain closer to the tooth surface. One+ includes both at a combined 10% concentration. Read nano vs micro hydroxyapatite toothpaste.
07 Hydroxyapatite vs nano-hydroxyapatite: what’s the difference?
They are the same mineral in different particle sizes. Nano-hydroxyapatite particles are under 100 nanometers; micro particles are larger. Research looks at how smaller particles reach microscopic surface defects while larger ones stay nearer the surface. One+ uses both, 10% combined. Nano vs micro, explained.
08 What's the actual ingredient list?
Water, Sorbitol, Glycerin, Potassium Sorbate, Hydroxyapatite (nano & micro), Xylitol, Sodium Cocoyl Glutamate, Cellulose Gum, Xanthan Gum, Zinc Citrate, Aloe Vera, Mentha Piperita (Peppermint) Oil, Mentha Viridis (Spearmint) Leaf Oil, Menthol, Sodium Benzoate, Stevia Rebaudiana Leaf/Stem Extract. Paste any toothpaste list into the toothpaste ingredient checker.
09 How can I check another toothpaste’s ingredients?
Paste the list from the box or tube into the free toothpaste ingredient checker. It flags hydroxyapatite, fluoride, SLS, artificial dyes, xylitol, and other common ingredients, with a short explanation of each. Matching runs in your browser and is not saved.
10 How do I compare ingredients across adult toothpastes?
Paste any label into the ingredient checker, or compare 50 brands under one set of rules in the 2026 Transparency Report. For hydroxyapatite brands, the comparison tool lines up HAp percentage, fluoride, SLS, and price per ounce.
11 How can I tell effective ingredients from marketing claims?
Start with the Drug Facts panel. A cavity, gum, or sensitivity claim names its active ingredient and strength there. Words like natural, clinically proven, or dentist recommended need a cited study or the full ingredient list to mean anything. Ten common claims, decoded.
12 What does “all-in-one” mean on a toothpaste?
It means the brand claims several benefits from one tube. On the Crest Pro-Health Advanced and Colgate Total SF labels, a single active, stannous fluoride 0.454%, carries the cavity, gingivitis, and sensitivity uses. Whitening and fresh-breath claims are cosmetic. More box claims.
13 What does “clinically proven” mean on toothpaste?
Only that some study tested something. Ask which formula was tested, for what outcome, and in how many people. A study of a different formula does not transfer to the tube in your hand, which is why Klyyr labels every study it cites with the formula it tested.
14 How do I use One+ hydroxyapatite toothpaste?
Brush twice daily with a pea-sized amount for two minutes, then spit. Follow the product directions and any advice from your dentist.
15 Can children use it?
For children under 3, use a rice-grain amount; for ages 3–6, use a pea-sized amount. A caregiver should supervise brushing and encourage children to spit rather than intentionally swallow. Ask your child's dentist about individual needs, especially when switching from fluoride. See hydroxyapatite toothpaste for kids.
16 Is it safe to swallow hydroxyapatite toothpaste?
Spit after brushing. Do not swallow toothpaste. Supervise children, use the amounts above, and ask a dentist about individual needs. We do not describe One+ as kid-safe or safe if swallowed.
17 Can I switch from fluoride toothpaste to One+?
You can change your daily toothpaste. Do not stop a fluoride routine your dentist prescribed without asking them first, especially for children or if you have high cavity risk.
18 Is 10% hydroxyapatite the right concentration?
One+ uses a combined 10% nano + micro blend. Ten percent is not a universal efficacy threshold. The 18-month non-inferiority study used a 10% HAp toothpaste of a different formula. Read 10% hydroxyapatite toothpaste.
19 Does hydroxyapatite help with sensitive teeth?
Hydroxyapatite toothpastes have been studied for dentin sensitivity, including their interaction with exposed tubules. Those studies evaluated other formulas, so they do not guarantee a result from One+. Talk with your dentist if sensitivity is severe, new, or persistent. Read hydroxyapatite toothpaste for sensitive teeth.
20 Does hydroxyapatite whiten teeth?
One+ is not a peroxide bleach and is not intended to change your underlying tooth color. Laboratory studies have measured surface-stain removal with other hydroxyapatite toothpastes, but those results are not a Klyyr clinical claim.
21 Does natural toothpaste remove surface stains?
Stain removal depends on the cleaning ingredients, not on the word natural. Abrasives such as hydrated silica, calcium carbonate, and baking soda lift surface stains; they do not change the shade of the tooth. An in-vitro experiment measured stain removal after 180 seconds for another commercial HAp toothpaste. See natural toothpaste and does HAp whiten teeth?
22 How do I read a whitening toothpaste label?
Find the whitening route: a peroxide or PAP, an abrasive such as hydrated silica or baking soda, an optical ingredient, or nothing at all. Our audit of 23 whitening claims found 4 that list a peroxide and 5 that name no whitening ingredient.
23 Do whitening toothpastes contain SLS?
Some do. 6 of the 23 whitening pastes in our 2026 audit list sodium lauryl sulfate, including Crest 3D White Brilliance and Colgate Total SF Whitening. The other 17 do not. Every SLS toothpaste we recorded.
24 How long does remineralization take?
There is no guaranteed personal timeline. Studies of other hydroxyapatite toothpaste formulas measure different outcomes over periods ranging from weeks to months. Use One+ consistently as directed and talk with a dentist about persistent sensitivity, pain, or enamel concerns.
25 Can I use it during pregnancy?
All 16 ingredients are disclosed so you can review them with your dentist or OB. Pregnancy can change oral-health needs, so ask your care team before making a material change to your routine.
26 Can I use hydroxyapatite toothpaste with other oral care products?
Yes. One+ can be used with flossing, tongue cleaning, and mouthwash. Follow each product's directions and ask your dentist how to sequence products prescribed for a specific concern.
27 Do I need floss and mouthwash as well as toothpaste?
Toothpaste and a brush clean the surfaces you can reach. Floss or interdental brushes clean between teeth, where a brush misses. The ADA recommends brushing twice a day and cleaning between your teeth once a day. Mouthwash is an add-on, not a replacement for either. See the two-step routine and floss before or after brushing?
28 How long should I wait to brush after acidic food or drinks?
Wait 30 to 60 minutes. Acid softens the enamel surface, and brushing right away can wear it down. In the meantime, rinse with water so saliva can neutralize the acid. Why the wait matters.
29 Can I use One+ with braces or aligners?
You can use One+ as a daily toothpaste while wearing braces or aligners unless your orthodontist has prescribed a different paste. Follow their instructions for around brackets, trays, and any fluoride protocol they recommend.
30 Does One+ have the ADA Seal of Acceptance?
No. One+ does not carry the ADA Seal of Acceptance. The Seal is a separate program and is not required to sell toothpaste. Ask your dentist whether a fluoride-free routine is appropriate for you.
31 How is One+ different from other hydroxyapatite toothpastes?
One+ discloses a combined 10% nano + micro hydroxyapatite blend, lists all 16 ingredients, uses peppermint + spearmint, and contains no SLS and no artificial dyes. Compare public labels in Klyyr vs Boka, Klyyr vs David's, and Klyyr vs RiseWell. For the Exact-Net dentist ranking, read Best Overall, or start with best hydroxyapatite toothpaste.
32 How do Bite and Boka compare?
Bite makes chewable toothpaste tablets and Boka makes a paste. Both list nano-hydroxyapatite without a percentage, and neither contains fluoride or SLS in the versions we compared. Bite cleans with calcium carbonate, Boka with hydrated silica, and only Boka publishes an RDA range. Bite vs Boka, label by label.
33 Do remineralizing toothpaste tablets work?
Tablets carry the same kinds of actives as pastes, such as fluoride or nano-hydroxyapatite, in dry, pre-measured form. Results for one tablet do not transfer to another, so check the active and its amount on the label. Tablets vs toothpaste covers the trials.
34 What flavor is One+?
Peppermint + spearmint, with menthol also listed. There are no artificial dyes.
35 Does One+ contain SLS or artificial dyes?
No. One+ has no SLS and no artificial dyes. It uses sodium cocoyl glutamate as the surfactant. Read SLS-free hydroxyapatite toothpaste, or paste a label into the toothpaste ingredient checker.
36 Which toothpaste brands contain SLS?
In our 2026 audit, 14 of 50 toothpastes listed sodium lauryl sulfate, from Aquafresh, Arm & Hammer, CariFree, Close-Up, Colgate, Crest, Marvis, Parodontax, Apagard, and Sensodyne. One+ contains no SLS. The full list.
37 How much does One+ cost?
Price starts at $12.95 per tube (120 g / 4.23 oz) for a one-time 1-tube order. That is the discovery and comparison price. A 2-pack is $24.95 and a 3-pack is $33.95.
