Quick verdict: FortBite is a tooth powder brushed on twice daily, made from bentonite and kaolin clay, calcium carbonate, cinnamon, clove and myrrh. No fluoride is listed. The page states both a 60-day and a 180-day guarantee.

Unlike most products on this site, FortBite is not a supplement you swallow. It is meant to be brushed onto your teeth. That changes how you should judge it.

What is FortBite?

FortBite is a powder sold in jars. According to the official FAQ, you put a small amount on your toothbrush, brush teeth and gums for about two minutes, then rinse and spit. The brand recommends doing this twice daily, morning and night. In other words, FortBite positions itself as a replacement for, or an addition to, toothpaste.

What's in FortBite, according to the official website?

The page says the formula has 11 ingredients and names these:

• Bentonite clay
• Kaolin clay
• Calcium carbonate
• Natural cinnamon extract
• Clove
• Peppermint
• Myrrh
• Ginger
• Lemon peel
• Stevia (as a sweetener)

That is ten named items; the eleventh is not identified in the page text. No amounts are listed. Fluoride is not among the named ingredients.

Why does fluoride matter when choosing a tooth powder?

This is the most important point on this page. Fluoride toothpaste is the cornerstone of cavity prevention according to the NIDCR and the CDC. If you replace your fluoride toothpaste with a fluoride-free powder, you lose that protection. If you want to try FortBite, a safer approach is to use it in addition to fluoride toothpaste, or ask your dentist.

What does the research say about FortBite's ingredients?

• Calcium carbonate is a common mild abrasive in toothpastes. It helps clean, but abrasiveness also matters for enamel and sensitive gums. The page does not publish an abrasivity rating.
• Bentonite and kaolin clays are absorbent minerals. The sales page cites a short review of bentonite as a "natural remedy" and a cell study of kaolinite. Neither shows that brushing with clay protects teeth in people. In 2016 the FDA warned consumers not to use certain bentonite clay products because of high lead levels, so sourcing and testing matter; ask the vendor for a certificate of analysis.
• Cinnamon, clove, peppermint, ginger: the NCCIH and its pages on ginger and peppermint oil discuss mostly digestive and metabolic uses; oral-care evidence is limited. Cinnamon can irritate the mouth in sensitive people.

Several references on the FortBite page are unrelated to teeth, including papers on pancreatitis guidelines, reflux devices and concrete made with clay, and an art-history dissertation. That does not inspire confidence in the reference list.

How much does FortBite cost?

FortBite is offered as 1 jar, 3 jars or 6 jars. Prices load by script and do not appear in text, so check the current price on the official website. The page says every order ships free in the US and that 3- or 6-jar orders include two bonus guides.

What is FortBite's money-back guarantee? The page says two things

The sales page displays a 60-day guarantee box and a 180-day guarantee box, and its FAQ repeats both numbers in consecutive sentences before saying to contact them "within the first 60 days." The separate refund policy page states 60 days from delivery and asks for all bottles and the packing slip. Until the vendor clarifies, plan on 60 days and confirm the term on your receipt at checkout.

How can you use a tooth powder without harming enamel or gums?

If you decide to try FortBite, a few habits reduce the risk that comes with any abrasive powder:

1. Use a soft-bristled toothbrush and light pressure; scrubbing hard with a powder wears enamel and irritates gums.
2. Use a small amount, as the official directions suggest, rather than packing the bristles.
3. Keep a fluoride toothpaste in your routine, for example fluoride at night and the powder in the morning, or as your dentist advises.
4. Stop and see a dentist if you notice new sensitivity, gum irritation or a burning feeling, which can happen with cinnamon.
5. Keep the jar closed and dry so the powder does not clump or pick up moisture.

Who might want to try FortBite?

• People curious about tooth powders who will keep using fluoride toothpaste as well.
• Those who like spice-flavored, sugar-free oral care.

Who should skip FortBite or ask a dentist first?

• Anyone at higher risk of cavities, who should not drop fluoride.
• People with sensitive teeth, exposed roots or receding gums, since abrasive powders can make sensitivity worse.
• Children. The page says the product suits all ages, but children's oral care should follow a dentist's advice.
• People allergic to cinnamon, clove or other spices.

What are the downsides of FortBite?

• No fluoride among the listed ingredients.
• Unknown abrasivity and no clay testing data on the page.
• Conflicting guarantee terms.
• Customer stories on the page make strong claims, such as being able to chew ice, which we cannot verify and would not recommend.
• Off-topic references in the scientific list.

How does FortBite compare with Power Bite?

Both are non-capsule products, but they work differently. FortBite is brushed and spat out; Power Bite dissolves in the mouth at night. Power Bite contains xylitol; FortBite relies on clay and calcium carbonate for cleaning. Neither replaces fluoride toothpaste.
