BioDentex Review: What It Is, What It Costs and Where to Buy It

What is in BioDentex

Six ingredients are named, and no amounts are given for any of them:

• Xylitol and stevia, two sweeteners.
• Cranberry, grape seed extract and peppermint, three plant ingredients.
• Carrot powder, a food powder.

Everything else is a proprietary blend of 11 or more plants and minerals, none of them named. There is no Supplement Facts label and no daily number of capsules, so you cannot tell how much of anything you would take. A typical capsule holds less than a gram of powder in total, shared between at least 17 ingredients.

Why a capsule is the wrong way to take xylitol

Xylitol is the one ingredient here with real dental research behind it. Mouth bacteria that cause decay cannot use it for energy the way they use sugar, so they make less acid. But that only works while the xylitol is in your mouth, in contact with the teeth and the bacteria on them.

Once it is swallowed, xylitol does nothing for the teeth. If you want to use it, sugar-free xylitol gum after meals is a cheap way to keep it where it can act.

What the research shows, at a glance

BioDentex itself has never been tested in a published study, so these ratings are for its named ingredients, from the studies in our full review:

• Xylitol: a 2015 Cochrane review of 10 studies with 5,903 people found low-quality evidence that a fluoride toothpaste with 10% xylitol may reduce decay in children by 13% more than fluoride toothpaste alone, over two and a half to three years. A 2025 review found that xylitol gum reduces decay-causing bacteria and plaque as an add-on to brushing.
• Cranberry: its compounds stop some mouth bacteria sticking to surfaces in the laboratory. We found no trials showing that cranberry capsules protect teeth or gums.
• Grape seed extract: studied mainly in the laboratory, applied directly to tooth surfaces.
• Peppermint: freshens breath in toothpaste or mouthwash; swallowed in a capsule, it does not.
• Stevia and carrot powder: no evidence for teeth or gums.

A chocolate in the emails, a capsule in the bottle

The emails the seller writes for affiliates describe BioDentex as a soft “dental chocolate” that you “chew”, that will “rebuild your teeth from the inside out”, and that let a 67-year-old woman “cancel her $15,000 implants”. The product you receive is a capsule you swallow with water.

If an email like that brought you here, keep two things in mind. A capsule cannot do what a chewed product might, because nothing stays in the mouth. And no chewed or swallowed product can rebuild lost enamel or replace an implant. Implants, fillings and crowns are recommended because lost tooth structure does not come back.

What actually protects teeth and gums

The habits with the strongest evidence are cheap, and none of them needs a supplement:

Our tooth decay guide and gum disease guide cover what the research shows in more detail.

When to see a dentist instead

Some of the problems that lead people to dental supplements are signs of decay or gum disease that need treatment, and they tend to get worse, and more expensive, while you wait.

• Bleeding gums when you brush are the most common early sign of gum disease, which a dentist or hygienist can treat.
• Sensitive teeth can mean worn enamel, gums that have pulled back from the roots, or a cavity.
• A loose tooth in an adult usually means advanced gum disease.
• Toothache or a bad taste that does not go away needs an examination.

Side effects and who should be careful

• Dogs: xylitol is highly toxic to dogs, even in small amounts, so keep the bottle where a dog cannot reach it.
• Stomach: large amounts of xylitol can cause gas and loose stools; a capsule is unlikely to hold enough to matter.
• Medicines: because most of the formula is an unnamed blend, you cannot check it for interactions. Ask a pharmacist first if you take regular medicines.
• Pregnancy and breastfeeding: the unnamed ingredients make it impossible to judge, so ask your doctor or midwife first.

How BioDentex is marketed

A few things about the marketing are worth knowing before you buy:

• University logos: the sales page shows the logos of Harvard, Stanford, Yale and Columbia, none of which has any connection with the product. Its only link to any of them is a general Harvard Health article about gum disease and heart health.
• Who is behind it: the product is presented by a man described only as a research scientist, with no qualifications, institution or published work given.
• Two descriptions: the affiliate emails sell a chewable chocolate; the product page sells a capsule.
• The warehouse: returns go to a fulfilment centre in Aurora, Colorado, that handles several other products sold through ClickBank.

Which package makes sense?

There is no single bottle. Two bottles cost $158 ($79 each) plus shipping; three cost $207 ($69 each) and six cost $294 ($49 each), both with free US shipping and bonus guides. It is a one-time payment, not a subscription. International orders are charged $30 shipping for each bottle, and that is not refunded.

Because there is no label, you cannot check a single dose before you buy, and the refund needs every bottle back. Two bottles is the most we would risk.

• Two bottles ($158 plus shipping) are the smallest order, with the fewest bottles to post back if you want a refund.
• Six bottles ($294) give the lowest price per bottle, but commit you to half a year of a formula with no published amounts.

How to take it, if you try it

• Read the bottle on arrival: look for a label, a daily dose and any warnings, since none is published online.
• Keep brushing: use it alongside fluoride toothpaste and cleaning between the teeth, never instead of them.
• Keep your dental appointments, and see a dentist about bleeding gums, sensitivity or pain.
• Stop if you get stomach upset or any reaction, and keep the bottle away from dogs.
• Diary the deadline: the refund depends on the bottles arriving back within 90 days of purchase.

How the 90-day refund works

1. Contact support first and ask for return instructions, giving your order number.
2. Send back every bottle you received, empty, full or partly used, including any bonus bottles, with your name, address, email, phone number and packing slip.
3. Make sure it arrives in time: the parcel must reach the fulfilment centre in Aurora, Colorado, within 90 days of the original purchase date. You pay the return postage.
4. If you get no reply, ClickBank’s order support at clkbank.com can help, because ClickBank processed the payment.
