Part of our DentalPrime overview. Last checked October 28, 2026.
Dental Prime ingredients, as the vendor lists them, are vitamin D3, vitamin K2 (MK-7), calcium as "Micro Crystalline Hydroxyapatite Complex", xylitol, cranberry powder and zinc citrate, with magnesium added on the video page[1][2]. None has an amount. DentalPrime publishes no Supplement Facts panel, so 0 of 7 doses can be checked against any study, and nobody can tell you whether the tablet holds a useful amount of anything.
DentalPrime ingredients at a glance
Seven ingredients appear across the vendor's pages, and none has a published dose. The "role claimed" column quotes the vendor's video page, which describes several ingredients with joint-pain wording rather than dental wording[2]. Grades refer to oral-health evidence in our files.
| Ingredient (form) | Role claimed by vendor | Amount disclosed? | Oral-health evidence grade |
|---|---|---|---|
| Calcium (as hydroxyapatite) | "the identical mineral compound that naturally makes up your tooth structure"; also "remedy for arthritis" | No | Moderate as toothpaste; Weak as a tablet |
| Xylitol | Listed, no amount | No | Moderate (gum, toothpaste, rinse) |
| Cranberry powder | "flushing out fluoride and toxins" | No | Limited |
| Vitamin K2 (MK-7) | Co-factor that steers calcium "to your teeth" | No | No dental trial; Avoid on warfarin |
| Vitamin D3 (cholecalciferol) | "detoxifies the body, relieves joint pain" | No | No dental trial in our files |
| Zinc (citrate) | "superfood for joint relief" | No | No dental trial in our files |
| Magnesium (video page only) | Listed, no amount | No | No dental trial in our files |
What is in each ingredient, and what does research say?
Three of the seven have oral-health trials, and those trials mostly put the ingredient in direct contact with the teeth. The other four have no dental studies in our evidence files. Doses studied are listed so you can see what DentalPrime would need to match.
Hydroxyapatite (calcium)
Hydroxyapatite is the calcium phosphate mineral that makes up most of tooth enamel. As toothpaste it has the best data of any ingredient here: an 18-month trial in 189 adults found it non-inferior to 1450 ppm fluoride toothpaste[4], and an updated meta-analysis of 5 trials supports it as an anti-caries active[5]. Swallowed, it has been studied only as a calcium source for bone, at 1 g of calcium a day[6]. No swallowed tablet trial for teeth was found. Grade: Moderate as toothpaste, Weak as a tablet.
Xylitol
Xylitol is a sugar alcohol used in sugar-free gum. A Cochrane review found low-quality evidence that fluoride toothpaste with xylitol beat fluoride-only toothpaste for cavities in children's permanent teeth[7]. A systematic review found it likely lowers mutans streptococci without changing the wider oral microbiota[8]. Trials used gum, toothpaste, rinses and lozenges. Grade: Moderate, for those forms.
Cranberry
Cranberry contains proanthocyanidins, proposed to stop bacteria sticking to teeth. A cranberry drink lowered plaque and gingival scores in people with gingivitis[9]. A tablet pairing a paraprobiotic with cranberry extract cut new early cavities over 9 months in preschoolers[10]. Doses varied and are not comparable to an unknown amount of powder. Grade: Limited.
Vitamin K2 (MK-7)
MK-7 is a long-acting form of vitamin K2. At 180 mcg a day for 3 years it slowed bone density loss in 244 postmenopausal women[11]. No dental outcome was measured. The NIH Office of Dietary Supplements warns of a "serious and potentially dangerous interaction" with warfarin[12].
Vitamin D3, zinc and magnesium
Our evidence files hold no dental trials for these three. The NIH Office of Dietary Supplements sets adult upper limits of 4,000 IU a day for vitamin D, 40 mg for zinc and 350 mg for supplemental magnesium. With no label amounts, we cannot say how DentalPrime compares to those limits or to any study dose.
How transparent is the DentalPrime formula?
Not transparent. A normal label shows a Supplement Facts panel with each amount per serving; DentalPrime shows ingredient names only, checked October 28, 2026[1]. There is no blend total either, so no arithmetic is possible: even a "proprietary blend" usually states its combined weight.
The lists also differ between the vendor's own pages:
- Home page: six ingredients[1].
- Video page: adds magnesium[2].
- Text page: adds a "proprietary blend of trace mineral activators" with no contents or weight[3].
No page lists fillers, binders or an allergen line. If a third-party site prints a fuller DentalPrime label, the vendor's own pages remain the reference; ask the seller for a label photo before you trust another list. The video FAQ also names a different product, "DentaGuard Plus", a sign of reused copy[2].
Ingredient safety and interactions
The main flag is vitamin K2: anyone on warfarin or another vitamin K antagonist should ask their doctor first. In people on anticoagulants, MK-7 at just 10 to 20 mcg a day lowered INR in a clinically relevant way in many volunteers[13]. Calcium can lower absorption of levothyroxine, some antibiotics and bisphosphonates[14]. A study linked higher blood xylitol to cardiac events and found a xylitol drink raised platelet activity[15]. The full list, with symptoms to watch, is on our DentalPrime side effects page.
Do these ingredients prove DentalPrime works?
No. Ingredient studies show what a known dose does in a set form, usually toothpaste, gum or a drink. DentalPrime is a swallowed tablet with no published doses and no trial of its own. That leaves the product claim untested, as we explain in does DentalPrime work. If you still want to try it, compare the bottle counts on our DentalPrime price guide and keep up your normal toothpaste and dental checkups.

Frequently asked questions
What are the ingredients in Dental Prime?
The vendor names vitamin D3, vitamin K2 as MK-7, calcium as hydroxyapatite, xylitol, cranberry powder and zinc citrate. The video page adds magnesium, and the text page adds a trace mineral blend. No amounts are given for any of them, checked October 28, 2026.
How much hydroxyapatite is in DentalPrime?
The vendor does not say. DentalPrime publishes no Supplement Facts panel, so the hydroxyapatite amount, like every other dose, is unknown. Swallowed hydroxyapatite has only been studied for bone, at 1 g of calcium a day.
Does DentalPrime contain fluoride?
Fluoride is not among the ingredients the vendor names, and its sales copy is built around avoiding fluoride. Because no full label or Supplement Facts panel is published, the complete contents of the tablet cannot be confirmed.
Is the xylitol in DentalPrime enough to help teeth?
Unknown. Xylitol trials used gum, toothpaste, rinses and lozenges that stay in the mouth, and DentalPrime gives no xylitol amount. Without a dose, nobody can compare the tablet to those studies.
Why does the DentalPrime ingredient list change between pages?
The home page lists six ingredients, the video page adds magnesium and the text page adds trace mineral activators. The vendor does not explain the difference. Ask the seller for a photo of the actual bottle label before buying.
