Quick answer: DentaTonic's seven listed ingredients all appear in Synadentix too. Synadentix adds guava powder, glucose oxidase and amyloglucosidase, is taken at bedtime and has a 90-day guarantee. DentaTonic is a tablet with water and a 60-day guarantee.

Both products are built around the same idea: support the natural antibacterial proteins found in saliva. Here is how they line up.

What do Synadentix and DentaTonic have in common?

Both are sold through BuyGoods and both list a proprietary blend of enzymes and proteins with microcrystalline hydroxyapatite. DentaTonic's page talks about "replenishing" lactoperoxidase in saliva; Synadentix's page talks about boosting "healing saliva flow" at night.

Ingredient comparison

Neither page publishes amounts.

How are Synadentix and DentaTonic taken?

• Synadentix: let one tablet melt under the tongue or chew it slowly at night before bed.
• DentaTonic: take one tablet a day with a glass of water.

For a product whose ingredients are meant to work in the mouth, dissolving it slowly (the Synadentix approach) is more consistent with the concept. Swallowing a tablet with water sends it straight to the stomach.

What does the research say about the shared ingredients?

Lysozyme, lactoferrin and the lactoperoxidase system are genuine parts of saliva's defenses, reviewed in the Journal of Dentistry. Hydroxyapatite has supportive evidence when used in toothpastes, mouthwashes and gels, though a 2025 commentary questioned how strong that evidence is. What is missing for both products is evidence that a chewable or swallowed tablet changes saliva or teeth in people.

Who should be careful with both?

• People allergic to milk proteins: lactoferrin and lactoperoxidase are commonly milk-derived; check each label.
• Pregnancy, breastfeeding and use by minors, which call for medical advice first.
• Anyone taking medicines; the enzyme blends are not fully characterized on the pages.
• Anyone with gum symptoms who has not had a dental exam.

What claims should you discount on both pages?

DentaTonic's FAQ says all ingredients are "proven to be safe in clinical trials" and that the product suits "all ages and medical conditions," and it mentions protecting against hydrogen cyanide. Synadentix claims its ingredients enter the bloodstream to detox the body and protect the brain. None of these points are backed by citations to studies of either product, so we treat them as marketing.

How should you set up a fair trial of either product?

• Pick one product, not both, so you can tell what is doing what.
• Write down your starting point: how your breath, gums and any sensitivity feel, and what your dentist said at your last checkup.
• Keep everything else the same: same toothpaste, flossing and diet.
• Mark your calendar for a check-in well before the refund deadline: day 50 for DentaTonic, day 80 for Synadentix.
• Keep the box, bottles and packing slip, since both require them for a refund.

Is a hydroxyapatite toothpaste a simpler alternative?

If hydroxyapatite is the ingredient you care about most, a toothpaste that contains it delivers it where the research was done: on the tooth surface. The 2024 systematic review studied toothpastes, mouthwashes and gels, not chewables. Ask your dentist whether a hydroxyapatite or fluoride toothpaste is the better fit for your cavity risk.

The same logic applies to the enzymes. Some toothpastes and dry-mouth products are formulated with lysozyme, lactoferrin or lactoperoxidase so that they act in the mouth. If dry mouth is your main complaint, the NIDCR dry mouth page lists causes, including many medicines, that are worth discussing with your doctor before reaching for a supplement.

Bottom line on Synadentix vs DentaTonic

If the saliva-protein idea interests you, Synadentix is the more complete version of the shared formula and has the friendlier refund window, while DentaTonic is the simpler, lower-commitment entry. Read the full Synadentix review for more detail, and keep brushing with fluoride toothpaste either way.
