1. Chew one daily for 30 seconds.
Preferably after brushing, but still works fine if not.

2. After 30 seconds, let whatever's left dissolve naturally.
This allows minerals to penetrate deep into weakened enamel structure.

3. Don't rinse for about 5 minutes
Works morning or night, with any oral care routine you already use.

Three ingredients. One complete system. Each one builds on the last.

1. Hydroxyapatite helps support your enamel.
It's the exact mineral your teeth are made of — absorbed directly into porous enamel to help fill gaps and support structural density.

2. Xylitol accelerates absorption.
It clears stain-causing bacteria and balances pH so hydroxyapatite absorbs deeper and faster — naturally brightening as it works.

3. Oral probiotics help protect what you've built.
By restoring healthy saliva production, your mouth continuously delivers minerals to your enamel between doses — around the clock.

Absolutely.

Every ingredient in SmileGuard is 100% natural and dentist-recognized.

1. Hydroxyapatite is exactly what your enamel is made of.

2. Xylitol and oral probiotics have been used in dentistry for decades.

3. Guava Fruit Powder has been as natural flavoring for centuries

100% natural & safe ingredients. Expert-Formulation. Engineered in a certified US facility in Denver, CO.

Most people begin noticing changes within 1-2 weeks.

But for many, this isn't a quick fix—it's helping support decades of mineral loss, so results improve the longer you use it.

Week 1-2: Teeth may feel smoother. Early sensitivity may start to fade. You'll notice something's changing.

Week 4-6: Ice water, hot coffee—things that used to hurt may start to feel normal again. Yellowing may fade naturally without harsh bleaching.

Month 3+: Teeth may feel stronger, more solid. You're not just supporting years of wear—you're helping protect your smile for the decades ahead.

You're covered.

SmileGuard comes with a 90-day money-back guarantee — no questions asked. If you're not satisfied with your results within 90 days, you get a full refund.

Hydroxyapatite — Helps support enamel from the inside out by replacing the exact mineral your teeth are made of

Xylitol — Helps promote a naturally brighter smile while balancing pH so hydroxyapatite absorbs deeper and faster

3-Strain Probiotic Blend — Freshens breath and supports gum health, but more importantly boosts saliva production to continuously deliver minerals to your enamel

Guava Fruit Powder — 100% natural flavoring for a light, fruity taste you'll actually look forward to

    "After menopause my teeth just went dull. Yellow. Started hurting with cold drinks too. I thought it was just what happened getting older. Been using SmileGuard about 10 weeks and they genuinely look brighter, not fake white, just natural. The sensitivity is also getting slightly better daily and now I can finally have my morning iced coffee again."

    "My gums bled every time I brushed for three years straight. I tried every mouthwash, every soft bristle, every deep cleaning my dentist pushed. Nothing changed. Two months on SmileGuard and the bleeding has slowed down. My gums went from puffy and red to actually looking healthy again. My hygienist asked what I changed before I even brought it up."

    "Cold water made me wince. Biting into anything hard felt like a gamble. My dentist said the mineral loss started years ago and was accelerated by my constant whitening attempts — I just never noticed until it showed up as chronic, daily pain. I wish someone had told me about remineralization sooner. SmileGuard caught it before it was too late."

    What Results Could Look Like in Less than 3 Months...

    DAY 1
    MONTH 3

    Camilla, 56

    "I'd given up on my gums honestly. Bled every single time I brushed, every time I flossed, for years. My dentist kept pushing a graft, $4,200, and I just couldn't do it. Started SmileGuard because at that point what did I have to lose. By the third week I realized I wasn't spitting pink anymore. A month later my gums actually looked like gums again. Not swollen, not angry. Just normal. I forgot what normal looked like."

    DAY 1
    MONTH 3

    Dawn, 54

    "I've been whitening my teeth for years. They'd look great for maybe three weeks and then right back to yellow. WORSE every time. I didn't even realize the whitening was the problem until I found smile guard. Two months in, the sensitivity I'd been living with had become so dull that I drank ICED COLD water without wincing. On top of that, my teeth look better than they have in a decade. I'm pissed nobody told me sooner."

    DAY 1
    MONTH 3

    Bruce, 63

    "I took my teeth for granted in my 30s and 40s, and now at 60 I'm dealing with the consequences. The sensitivity is constant—ice water feels like a shock, my gums bleed when I brush, and every dental visit means another expensive filling. I was terrified I'd end up needing dentures like my mother. SmileGuard stopped the bleeding, the cold sensitivity is gone, and for the first time in years my dentist said 'no new cavities.' My teeth finally feel strong again."

    DAY 1
    MONTH 3

    Danica, 54

    "My mom had full dentures by 72. I watched the whole thing happen, tooth by tooth. So when I cracked a molar at 50 I genuinely panicked. But I've been on SmileGuard eight months now. No new cracks, sensitivity is way down, and my last two cleanings have been completely fine. My dentist hasn't mentioned anything alarming. I'm not going to call it a miracle. I'm just not scared every time I eat anymore."

    • Xylitol: Included to create the optimal pH environment for mineral absorption—also helps promote a naturally brighter smile

    • 3-Strain Oral Probiotic Blend: Supports healthy saliva production and balances oral bacteria—helping your mouth naturally deliver minerals to your enamel between doses.

    Why This Formula Actually Works

    SmileGuard isn't three random ingredients—it's a complete system. One supports enamel. One accelerates absorption. One helps protect what you've built. That's why SmileGuard works when nothing else does.

    Hydroxyapatite

    Xylitol

    Oral Probiotic Blend

    Hydroxyapatite

    This is what your enamel is literally made of. When it's lost from aging, whitening, or daily wear—your teeth weaken, yellow, and hurt. Replacing this mineral back onto your teeth is one of the best ways to help support healthy enamel for life.

    Xylitol

    Not only can it help reduce stain-causing bacteria to promote a visibly brighter smile—this process also clears the enamel surface and balances pH levels so hydroxyapatite can absorb deeper and faster. Dr. Blue included it because whitening means nothing if your enamel isn't supported.

    Oral Probiotic Blend

    Freshens breath and supports healthier gums—but that's not why Dr. Blue included it. These probiotics promote healthy saliva production, which is essential for mineral delivery to the teeth. This blend also helps limit harmful bacteria from producing acids that can weaken enamel over time.

    • Dr. Ophelia Blue

      For 26 years, I watched my patients do "everything right" while their oral health continued to decline and their smiles continued to fade. SmileGuard delivers a real solution: the mineral your teeth are made of - strengthening, whitening, and protecting aging smiles the way traditional dentistry never could.

      Founder of SmileGuard

    • Dr. Vincent Bove

      As an oral surgeon, I see what happens when enamel loss is ignored. SmileGuard's ingredients fight the root cause of extreme oral health issues, helping patients protect their natural teeth and reduce the likelihood of invasive procedures and/or dentures later on.

      Oral & Maxillofacial Surgeon

    • Dr. Levi Horowitz

      I don’t endorse products lightly, but Dr. Blue is one of the most respected minds in dentistry, so SmileGuard caught my attention. It's ingredients are exactly what aging teeth need. I take it myself—and I recommend it to patients with sensitivity, staining, or who want to protect their teeth long-term.

      More questions?

      We've Got Answers.

      Of course!

      SmileGuard contains hydroxyapatite—the same mineral your teeth are already made of. It only supports what your dentist already wants for you: stronger enamel, less sensitivity, and healthier teeth long-term.

      Many customers tell us their dentists noticed the improvement at their next checkup.

      Yes!

      SmileGuard is completely safe to take alongside any medications or supplements. Our formula contains only natural, well-researched ingredients that won't interfere with prescriptions.

      Most toothpastes don't contain hydroxyapatite—the actual mineral your enamel is made of. They clean and protect, but they can't rebuild what's already been lost.

      SmileGuard delivers hydroxyapatite directly to your teeth, and stays active for 12-24 hours so minerals actually absorb.

      30 days when taken once daily, as recommended.

      Every bottle of SmileGuard contains 30 chews.
