Supersmile is a professional teeth whitening brand founded in 1987 by Dr. Irwin Smigel, widely known as the Father of Aesthetic Dentistry. The brand’s core technology, Calprox, dissolves the protein film on teeth without abrasive scrubbing. Cosmetic dentists worldwide rank it the #1 most recommended whitening brand in the world.
Supersmile’s Professional Whitening Toothpaste scores a 65 on the Relative Dentin Abrasivity scale. The American Dental Association sets the safety limit at 250. That puts Supersmile 75% below the limit and 94% less abrasive than most competing whitening toothpastes. It also works on veneers, bonded teeth, and dentures — something most whitening products can’t claim.
This review covers how Supersmile works, what the clinical data says, how it compares to competitors, and whether the premium price tag is justified by real-world results.
What Is Supersmile?
Supersmile is a premium oral care brand founded in 1987 by Dr. Irwin Smigel, the founder and president of the American Society for Dental Aesthetics, and his wife Lucia Smigel. The brand operates today under Lucia’s leadership alongside their daughter Bellanca Smigel Rutter, and retails across thousands of locations globally. Supersmile holds the distinction of being the #1 most recommended whitening brand by cosmetic dentists worldwide, a claim backed by professional endorsements spanning four decades.
Who Created Supersmile?
Supersmile was created by Dr. Irwin Smigel, who invented the concept of aesthetic dentistry in the 1970s and developed Calprox to keep his patients’ bonded teeth white between visits. The original formula debuted out of Dr. Smigel’s Madison Avenue office in New York, where demand grew so quickly that patients lined up three deep for access. A feature in Mademoiselle magazine accelerated the brand’s visibility and prompted Lucia Smigel to scale the business into a full commercial operation.
Dr. Smigel’s original goal was straightforward: give patients a daily product that whitened naturally and protected dental restorations. The Calprox formula solved a specific clinical problem — conventional toothpastes used silica abrasives that scratched enamel and dulled veneers. Supersmile replaced abrasion with dissolution, targeting the protein pellicle rather than scraping at stains directly.
What Products Does Supersmile Offer?
Supersmile sells a full oral care system including whitening toothpastes, an accelerator gel, dissolving whitening strips, a sonic toothbrush, floss, gum, and a tongue cleaner. The flagship Professional Whitening Toothpaste retails at $25 for a 4.2 oz (119 g) tube. The Professional Whitening Accelerator, designed to pair with the toothpaste for faster results, costs $65 for 3.6 oz (102 g). The full Professional Whitening System bundles both for $45 in the small size.

What Is Calprox and How Does Supersmile Work?
Calprox is Supersmile’s proprietary blend of encapsulated calcium peroxide, phosphates, magnesium, and enamel-like minerals that dissolves the protein pellicle on teeth instead of scraping stains away. The protein pellicle is the sticky film that forms on teeth and binds stains from coffee, tea, and food. By dissolving this film, Calprox removes stains at the source without requiring harsh abrasives like silica or charcoal. The formula simultaneously remineralizes and strengthens enamel while whitening.
How Is Supersmile Different from Regular Toothpaste?
Supersmile uses dissolution chemistry instead of abrasion, giving it an RDA score of 65 compared to the ADA safety ceiling of 250 — placing it 75% below the abrasion limit set by the American Dental Association. Most conventional whitening toothpastes use silica or charcoal as their stain-removal mechanism. Those abrasives scratch stains off the enamel surface, but they also scratch away enamel itself over time. Enamel does not regenerate once lost.
Supersmile’s manufacturing process also sets it apart. Each batch of toothpaste undergoes a 72-hour production cycle versus the 3 hours typical for conventional toothpaste. The extended process preserves the integrity of the Calprox formula and ensures consistent potency in every tube. Supersmile also reports the toothpaste fights plaque 10 times better than leading plaque-removing toothpastes based on internal clinical comparisons.
How Do You Use Supersmile Correctly?
Supersmile requires a dry toothbrush, not a wet one — a critical difference from conventional toothpaste instructions that directly affects whitening performance and Calprox activation. Place a pearl-sized drop of Professional Whitening Toothpaste on a dry brush and use circular motions for 2 minutes, twice daily. When pairing with the Accelerator, apply a pearl-sized drop of both products simultaneously on the dry brush. The dry-brush method prevents dilution of the active Calprox formula and optimizes contact with the protein pellicle.
For Superstrips, handle the strips with dry hands and press firmly onto teeth without stretching. Saliva begins dissolving the strips within the first few minutes. Full dissolution takes approximately 15 minutes. Do not eat or drink while strips are in place, and wait 30 minutes after use before consuming food or beverages. Use one strip for the upper teeth and one for the lower per session.
What Are the Ingredients in Supersmile?
Supersmile’s Professional Whitening Toothpaste uses sodium monofluorophosphate as its active ingredient at 0.14% w/v fluoride ion, with a clean inactive formula featuring Calprox and enamel-strengthening minerals free of silica, charcoal, parabens, and SLS. Inactive ingredients include Water, Sorbitol, Dicalcium Phosphate, Calcium Carbonate, Sodium Bicarbonate, Titanium Dioxide, Cellulose Gum, Calprox, Sodium Perborate, Corn Starch, Magnesium Carbonate, Sodium Lauryl Sulfoacetate, and Sodium Saccharin. Sodium Lauryl Sulfoacetate (SLSA) is used in place of the harsher Sodium Lauryl Sulfate (SLS).
Is Supersmile Free of Harsh Chemicals?
Yes. Supersmile is formulated without silica, parabens, SLS, SLES, charcoal, harsh bleaching agents, known allergens, gluten, BPA, or animal by-products across its entire product range. The Accelerator uses Urea Hydrogen Peroxide as its active whitening booster, supported by Glycerin, Potassium Hydroxide, Carbomer, Sodium Saccharin, Etidronic Acid, and EDTA. Superstrips combine Hydrogen Peroxide, Hydroxyapatite, and Calprox in a dissolvable PVP-Pectin base with peppermint aroma. All formulas undergo rigorous clinical testing before commercial release.
What Supersmile Does NOT Contain:
- Silica — scratches enamel and dulls dental restorations over time
- Charcoal — highly abrasive; not approved by the ADA for whitening
- SLS / SLES — sulfates linked to mouth irritation and canker sore formation
- Parabens — synthetic preservatives with endocrine disruption concerns
- Gluten — excluded for users with celiac disease or gluten sensitivity
- BPA — excluded from packaging and formulation
- Animal by-products — fully vegan-friendly across the product range
Does Supersmile Actually Work?
Supersmile delivers clinically verified whitening results supported by multiple internal studies, with real-world reviews overwhelmingly confirming visible improvement within one to two weeks of consistent daily use. The Professional Whitening Toothpaste and Accelerator combination is clinically proven to whiten teeth an average of 6 VITA shades in 5 days. Superstrips deliver an average of 8 shades whiter in 7 days based on clinical data. The full Professional Whitening System claims up to 9 shades whiter with the dry-brush technique.
What Do Supersmile Reviews Say?
Supersmile earns consistently positive reviews across retail platforms, with users citing zero sensitivity, lasting whitening effects, and noticeable results within 7 to 14 days of daily use. One verified long-term purchaser named Sharon127 writes that despite daily coffee, iced tea, and chocolate consumption, her teeth remain white after years of use. Multiple reviewers specifically call out Supersmile as the only whitening product that works safely on bonded teeth — a gap most competing brands fail to address.
Sensitivity-related complaints are nearly absent from Supersmile reviews — a sharp contrast to peroxide strip brands. One verified buyer with ‘soft and sensitive teeth’ notes that every other whitening toothpaste caused pain, while Supersmile removed tough stains without any discomfort. Reviewers using the product for 10+ years consistently confirm whitening results hold with continued use. The recurring criticism is price, but most buyers continue repurchasing despite the cost.
Does Supersmile Work on Veneers and Bonded Teeth?
Yes. Supersmile is one of the only whitening systems clinically proven to safely clean and brighten veneers, bonded teeth, dentures, and dental restorations — a capability that hydrogen peroxide strips and bleaching gels cannot safely replicate. Calprox removes the protein pellicle and surface stains from dental materials using dissolution rather than oxidation, making it non-damaging to porcelain, composite bonding, and acrylic. Multiple verified reviewers describe it as their exclusive whitening solution specifically because of this restoration-safe property.
To be clear: Supersmile whitening on restorations removes surface stains and restores the original appearance of the material — it does not bleach dental work lighter than its manufactured baseline shade. For users with mixed natural and restored dentition, this still produces a visibly uniform, clean smile across all tooth surfaces. No other widely available daily toothpaste achieves this consistently.
What Are the Side Effects of Supersmile?
Supersmile is formulated to minimize sensitivity and irritation, with clinical evidence and real-world reviews consistently reporting little to no adverse reactions across diverse user populations. The Calprox mechanism eliminates the abrasive action responsible for sensitivity in silica-based toothpastes. The Accelerator contains Urea Hydrogen Peroxide, which theoretically carries some sensitivity risk at higher concentrations, but Supersmile’s internal clinical testing reports no significant sensitivity in study participants using the product as directed.
Reported Side Effects (Rare):
- Mild initial tooth sensitivity in a small subset of Accelerator users
- Adjustment period for dry-brush technique — users accustomed to wet brushing may find it unfamiliar at first
- Superstrips require dry hands for proper adhesion — moisture disrupts application
Is Supersmile Safe for Sensitive Teeth?
Yes. Supersmile is specifically designed for sensitivity-prone users, using non-abrasive Calprox chemistry that does not grind against enamel or expose dentinal tubules the way silica-based products can over time. Multiple verified buyers with clinically sensitive teeth describe it as the first whitening product to produce results without triggering pain. The toothpaste contains fluoride, calcium, and phosphates that actively remineralize and strengthen enamel during each brushing session — treating the structural source of sensitivity rather than just avoiding it.
How Much Does Supersmile Cost?
Supersmile is a premium-priced brand, with the Professional Whitening Toothpaste at $25, the Professional Whitening Accelerator at $65, and the two-piece system bundle at $45 for the small size. The Zina45 Sonic Pulse Toothbrush retails at $250 and occasionally sells for $187 (USD) on promotion. Accessible entry points include the whitening gum at $5 and floss at $12. Free shipping applies to orders over $75 on the official website.
Supersmile Pricing Overview:
| Product | Size | Price (USD) |
|---|---|---|
| Professional Whitening Toothpaste | 4.2 oz (119 g) | $25.00 |
| Professional Whitening Accelerator | 3.6 oz (102 g) | $65.00 |
| Professional Whitening System (small) | 2-piece bundle | $45.00 |
| Superstrips (dissolving strips) | Per box | Varies |
| Whitening Gum | 12-piece | $5.00 |
| Zina45 Sonic Pulse Toothbrush | 1 unit | $187-$250 |
Is Supersmile Worth the Price?
Supersmile commands a meaningful premium over drugstore toothpastes but undercuts professional in-office whitening, which typically costs $300 to $1,000 (USD) per session without long-term maintenance benefits. For users who see results — and the clinical data plus review consensus strongly suggests most users do — the value proposition holds. The $45 two-piece system offers a better per-unit price than buying the toothpaste and accelerator separately, and represents the most cost-effective entry into the full whitening system.
Here’s the practical breakdown: a $25 toothpaste is a significant step up from a $4 drugstore option. But Supersmile competes with professional dental cleaning costs, not with Colgate. Verified long-term users consistently describe repurchasing for 10 or more years without switching brands, which is a strong signal of genuine satisfaction. For first-time buyers, starting with the toothpaste at $25 gives a low-commitment way to test the system before committing to the full accelerator purchase.
How Does Supersmile Compare to Competitors?
Supersmile differentiates through non-abrasive Calprox technology, dental restoration compatibility, and a 40-year clinical track record that no mass-market whitening brand can match. Crest Whitening Strips and Snow use direct hydrogen peroxide bleaching on enamel, which is unsafe for use on veneers or bonded teeth. Charcoal toothpastes rely on abrasion, which Supersmile specifically identifies as enamel-damaging and which carries no ADA approval for whitening. Supersmile occupies a unique position bridging daily oral care and professional dental results.
Supersmile vs Crest Whitening Strips: Which Is Better?
Crest Whitening Strips use hydrogen peroxide gel on adhesive strips worn for 30 minutes per session, delivering faster initial whitening for users with natural enamel but carrying higher sensitivity risk and no compatibility with dental restorations. Supersmile’s toothpaste delivers gradual whitening across a 5-day window through daily brushing. Crest strips typically retail for $35 to $55 (USD) per box and are available in pharmacies without subscriptions or specialized shipping requirements.
The choice depends on the user’s dental profile. Crest wins for users who want faster visible whitening on natural teeth and a lower upfront cost per cycle. Supersmile wins for users with veneers or bonded teeth, users with sensitivity, and users who prefer whitening integrated into their existing daily routine without additional treatment sessions. Both are legitimate products with clinical support — the match depends on individual circumstances.
Is Supersmile Better than Charcoal Toothpaste?
Yes. Charcoal toothpaste is highly abrasive and has no ADA approval for whitening, while Supersmile’s 65 RDA score sits 75% below the ADA’s upper safety limit — making it a dramatically safer long-term alternative. The American Dental Association has specifically noted the lack of safety and efficacy data for charcoal dental products. Charcoal’s visual drama — the black paste, the dark foam — implies deep cleaning, but the mechanism is purely mechanical abrasion. Over time, charcoal toothpaste strips away the same enamel it’s marketed to protect.
Supersmile vs Key Competitors:
| Feature | Supersmile | Crest Strips | Charcoal Toothpaste |
|---|---|---|---|
| Whitening Mechanism | Calprox pellicle dissolution | Hydrogen peroxide bleach | Abrasive scrubbing |
| RDA Score | 65 (very low) | N/A (strip format) | 70-300+ (varies widely) |
| Safe on Veneers | Yes | No | No |
| Sensitivity Risk | Very low | Moderate | Low to moderate |
| ADA Recognition | 40 years clinical use | ADA-accepted | Not ADA-approved |
| Entry Price | $25 (toothpaste alone) | $35-$55 per box | $8-$20 |

Should You Try Supersmile?
Supersmile is one of the most scientifically grounded at-home whitening systems available, backed by 40 years of clinical research, worldwide cosmetic dentist endorsement, and a review record that consistently confirms real results without sensitivity. The Calprox technology addresses a genuine gap in the market: most whitening products sacrifice enamel safety for speed, or simply don’t work on dental restorations at all. Supersmile achieves whitening and enamel protection simultaneously, making it the logical choice for users who have had dental work or experience sensitivity with traditional whitening products.
And here’s the thing: for users with veneers, bonded teeth, or dentures, Supersmile isn’t just a good option — it’s the rare daily-use whitening toothpaste that the dentist won’t advise against. For users with natural enamel and no restrictions, the Professional Whitening System at $45 offers a cost-effective path to 6 shades whiter in 5 days. Start with the toothpaste alone at $25, evaluate results at the two-week mark, and add the accelerator if a faster outcome is desired. Forty years of verified results back the investment.
