Remineralize and whiten your enamel, with gum.

Minvelle contains nano-hydroxyapatite, which is the synthetic version of the mineral that makes up 97% of natural tooth enamel. Clinical research has documented its ability to fill microscopic gaps in the enamel structure where mineral content has been lost. It has been used in Japanese oral care since 1980 and was approved by Japan as an anti-cavity agent in 1993.

One piece a day, after a meal or an acidic drink like coffee, wine, or citrus. Chew it for at least 15 minutes to give the active ingredients enough contact time with your teeth.

Yes. All three active ingredients (nano-hydroxyapatite, xylitol, Chios mastic resin) have decades of safety data. Nano-hydroxyapatite has been used commercially in Japan for 45+ years with no significant safety concerns, and the European Commission has reviewed and accepted it as safe for oral care products.

Most whitening gums contain peroxides or abrasives that bleach surface stains but can weaken enamel over time. Minvelle works differently: it supports the enamel structure itself using nano-hydroxyapatite. The whitening effect comes from remineralization, not chemical bleaching.

In trials on nano-hydroxyapatite toothpastes, sensitivity changes are commonly measured in the 4-to-8-week range. Those are toothpaste trials, not gum trials. Surface whitening is gradual by design.

No. Minvelle is designed to complement your existing oral care routine, not replace it. Continue brushing twice daily and flossing. Minvelle adds active remineralization in between brushing sessions, one piece a day after your most acidic meal or drink.

It depends what you ask it to do. Whitening gum will not bleach your teeth a shade lighter the way a peroxide tray does. What it can do is lift and slow the surface stains coffee, tea and wine leave behind, while nano-hydroxyapatite refills the micro-roughness in enamel those stains cling to. Minvelle is built for exactly this: chew one piece a day, ideally right after coffee, for about fifteen minutes. One box is 18 pieces, 18 days of daily use. Most people notice less sensitivity first; the cleaner, brighter look builds gradually over the weeks that follow, not overnight.

If your teeth twinge at cold water or after coffee, that is usually enamel that has lost some of its mineral surface. A gum worth chewing for sensitivity should rebuild that surface, not just freshen breath. Minvelle uses nano-hydroxyapatite, the same mineral enamel is made of, to refill the micro-roughness where sensitivity starts, while xylitol calms the acid-producing bacteria that make it worse. Chew one piece a day, ideally after your first coffee, for about fifteen minutes. One box is 18 pieces, 18 days of daily use. Most people notice the sharp, cold-air twinge easing first, over the first few weeks of daily chewing.

Coffee stains are surface stains: the tannins in coffee, tea and wine cling to the micro-roughness in your enamel and darken it over time. The highest-value moment to act is right after your cup, when chewing floods your mouth with saliva that rinses loose pigments away before they bond, while nano-hydroxyapatite refills the micro-roughness those stains hold onto. Chew one piece a day, ideally straight after your morning coffee, for about fifteen minutes. It lifts and slows fresh surface stains rather than bleaching deeper discoloration, so the change builds gradually rather than overnight.

Yes. Xylitol is one of the few sweeteners that actively helps rather than harms. It is a natural sugar alcohol the bacteria behind cavities cannot ferment, so instead of turning it into enamel-eroding acid, they starve. Chewing also floods your mouth with saliva, which neutralises acid and carries calcium and phosphate back to the tooth surface. Each Minvelle piece carries 817 mg of xylitol alongside nano-hydroxyapatite, the mineral enamel itself is made of, so the same piece that quiets acid-producing bacteria also helps refill the micro-roughness where sensitivity and stains begin.

Yes, and it is one of the oldest chewing traditions for a reason. Chios mastic is a resin harvested only from Pistacia lentiscus trees on the Greek island of Chios, used for oral health for over 2,000 years. Clinical research shows antibacterial activity against Streptococcus mutans, the species behind cavities, plus anti-inflammatory effects on gum tissue. Minvelle uses real Chios mastic resin in its base, so each piece pairs that with nano-hydroxyapatite, which refills the micro-roughness where stains and sensitivity begin. We wrote up the full evidence in our guide to mastic gum benefits.

It depends entirely on what is in the gum. Sugar gum is bad for your teeth: the bacteria behind cavities feed on the sugar and turn it into enamel-eroding acid. Sugar-free gum is the opposite. Chewing it floods your mouth with saliva, which neutralises acid and rinses away food and loose pigments, and if it is sweetened with xylitol it also starves those acid-producing bacteria instead of feeding them. Minvelle goes one step further: alongside 817 mg of xylitol, each piece carries nano-hydroxyapatite, the mineral your enamel is made of, so the same chew that quiets bacteria also helps refill the micro-roughness where sensitivity and stains begin.
