Fluoride works by forming a fragile outer layer on teeth. Microcrystalline hydroxyapatite is the actual mineral that enamel is made of. Instead of coating teeth, it physically rebuilds them.

Real remineralization, no toxicity concerns, safe to swallow. The gold standard in Japan and the EU.

Bad breath isn't caused by what was eaten. It's caused by sulfur-producing bacteria living between teeth and on the tongue.

Xylo's 3-strain oral probiotic blend crowds those out and replaces them with friendlier strains. Breath that stays fresh without mints every two hours.

Xylitol is a natural sweetener cavity-causing bacteria literally cannot eat. When given xylitol instead of sugar, they starve. Studied for decades for its role in reducing cavity-forming bacteria.

Approved for dental use globally. Safe for daily use. Note: keep away from dogs.

Most customers notice fresher breath within 3-5 days - the mid-day mint reach starts dropping off. Less sensitivity to cold drinks usually shows up between 2-4 weeks as the hydroxyapatite plugs the open dentinal tubules. Cavity defense is cumulative and shows up at your next checkup.

Yes. Xylo is a complement to brushing and flossing, not a replacement. Use it after a regular brushing routine to lock in the benefits and reset the oral microbiome.

Absolutely. Xylo works alongside any toothpaste, with or without fluoride. Many customers use a hydroxyapatite toothpaste plus Xylo for maximum effect.

Xylo's ingredients are generally recognized as safe, but as with any supplement, please consult your OB/GYN before using during pregnancy or while nursing.

Xylo is formulated for adults. Children under 12 should use a kid-specific oral health supplement. Never give xylitol-containing products to dogs.

Then you don't pay. Every order is backed by our 30-day money-back guarantee. If you don't see fresher breath, less sensitivity, or a cleaner-feeling mouth, email help@aetherskincare.com within 30 days and ship the remaining product back. We refund you in full. We'd rather have a happy non-customer than an unhappy one.

Yes. Cancel, pause, skip, or change frequency anytime from your account in two clicks. No phone calls, no hold times, no "are you sure?" loops. We hate that as much as you do. The discounted subscriber price stays locked in for as long as you stay on, even if we raise prices later.

Yes. Hydroxyapatite, probiotics, xylitol, and guava are all safe and effective with any kind of dental work. The probiotics work in the mouth (not on teeth), the xylitol acts on bacteria across the mouth, and hydroxyapatite remineralizes natural enamel surfaces around existing dental work. No interactions, no warnings.

Naturally sweet and minty, like a slightly less intense Altoid that dissolves slowly. No artificial aftertaste, no chalkiness, no chemical zing. Most customers say it's the rare oral health product they actually look forward to - apparently we made dental care habit-forming. We're fine with that.

A regular mint masks bad breath for 20 minutes. Xylo tackles the source: probiotics crowd out odor-causing bacteria, hydroxyapatite rebuilds enamel, and xylitol starves the cavity-forming bacteria that mints actually feed. One is a 20-minute cover-up. The other is a daily oral health system. The price reflects what's inside (5 mg microcrystalline hydroxyapatite, 20 mg of a 3-strain probiotic blend, 325 mg guava polyphenols), not the wrapper.

Orders placed before 2pm ET ship the same day. 3-5 day delivery anywhere in the US, free on your first order, free on every subscription order. You'll get tracking the moment it leaves the warehouse.

Direct-only on purpose. Amazon's model rewards cheap fillers and random sellers stocking your same SKU at unpredictable prices. Direct lets us control freshness (probiotics need it), consistent pricing, and the subscription experience. If you ever see Xylo on Amazon, it's not from us.

Brushing is contact-time of about 2 minutes. Xylo dwells for the full dissolve plus the after-window - 30+ minutes of active ingredient contact. Plus toothpaste doesn't include probiotics or xylitol in meaningful amounts. They stack rather than overlap.

Mechanical cleaning gets food and buildup out. It doesn't remineralize enamel, doesn't change which bacteria live on the tongue, and doesn't starve cavity-forming microbes for 8 hours. Xylo handles the chemistry hardware can't.

Oil pulling can pull bacteria out mechanically but doesn't deliver any active ingredient. Xylo gives you the actives oil pulling can't - hydroxyapatite, probiotics, xylitol. If you've gotten benefit from oil pulling, you'll likely get more from this combo.

Most "xylitol gum" has 1g per piece, and most people chew 1-2 pieces a day - well below the studied dose. Xylo is built around xylitol as the base, plus three other actives gum doesn't have. Same insight, full dose, plus everything else.

Soft and slightly chalky like a Tums, not chewy. Dissolves in roughly 60-90 seconds when you don't bite into it. Most users let it sit on the tongue or against the inner cheek.

No. It dissolves into a smooth liquid in under two minutes. Nothing stays behind, nothing wedged.

Yes - actually one of the best times. Bacteria multiply most while you sleep, so the post-night-brush dose is when xylitol and probiotics work hardest. Just don't eat or drink for 30 minutes after.

Yes. Use whitening strips on their normal schedule, then take Xylo after. Hydroxyapatite actually helps reduce the sensitivity that whitening strips often cause. They pair well.

It's the perfect time to start. After a cleaning, enamel is at its most receptive to remineralization. Many customers begin Xylo right after a cleaning to lock in the benefits.

Continue normally up to the procedure. After surgery, ask your provider when to resume - usually within a day or two once you can chew comfortably. Xylo is safe with all standard dental work.

The strains in Xylo (L. salivarius, L. paracasei, L. acidophilus) are well-tolerated and used widely in autoimmune populations. That said, if you have a complex condition, share the ingredient list with your doctor before starting. Same caution we'd give a friend.

None known with common medications. If you're on antibiotics, take Xylo at least 2 hours apart from your antibiotic dose so the probiotic strains aren't immediately wiped out. Otherwise no known issues - check with your prescriber if you're on something specialized.

Every batch is third-party tested for lead, arsenic, cadmium, mercury, and microbial contamination before it ships. Hydroxyapatite is sourced from food-grade suppliers with COAs on file. Test reports available on request.

Yes. Xylo is 100% manufactured in the United States in an FDA-registered, GMP-certified facility, then shipped from our warehouse at Indiana Business Park, 14701 W. 65th Way, Arvada, Colorado. No overseas blending, no relabeling, no offshore "drop-ship" middlemen.

The strains in Xylo were specifically chosen for oral cavity survival - they're acid-tolerant and adhere to oral tissue. The chewable format also lets them dwell directly on the tongue and inner cheek, where they need to be. Studies on these strains show meaningful colonization within 2-4 weeks of daily use.

Two reasons: dose and combo. Most xylitol gums have 1g per piece, and most people chew 1-2 pieces a day - well below the studied dose. Xylo delivers a higher daily xylitol load plus three other actives that fix problems gum can't (enamel, microbiome, gum tissue).

Hydroxyapatite remineralizes weakened areas and can rebuild enamel mineral content over time. Mild to moderate enamel loss responds well with consistent use. Severe visible erosion may need professional restoration - but Xylo helps prevent further loss in either case.

$60 is the one-time price. With Subscribe & Save it's $28/month - about $0.93 a day, less than a stick of gum and far less than a single dental cleaning. The math swings hard in favor of subscription, which is what most customers go with.

We send you an email 3 days before each renewal with the order total and a "skip this shipment" link. No silent charges. You can cancel, pause, or change frequency in two clicks from your account.

Yes - the dose is per chewable, so two adults sharing one pouch a month is fine if each takes one daily (and you'll likely want to bump to a higher subscription frequency). Reminder: kids under 12 should use a kid-formulated supplement, and never share xylitol products with dogs (toxic to them).

The four ingredients are each backed by decades of clinical research, not influencer trends. Hydroxyapatite has 50+ years of dental literature. Xylitol has hundreds of caries-prevention studies. The probiotic strains are pharma-grade. We just packaged what works.

They might at first, then look up hydroxyapatite. It's the recommended remineralizing agent in Japan, the EU, and increasingly the US. Many forward-thinking dentists already recommend HAP toothpastes - Xylo extends that into a daily chewable. The science doesn't change because someone hasn't read up yet.

Pouch is roughly 4x6 inches and weighs less than a Chapstick. Fits in any carry-on or dopp kit. No spill, no mixing, no liquid-rules issues at TSA. Each pouch holds 30 chewables - enough for a long trip.

Try Xylo for 30 days. If you don't notice fresher breath, less sensitivity, or healthier-feeling teeth, email help@aetherskincare.com within 30 days and ship the remaining product back for a full refund.
