  • Our take on the Extra White Accelerator

    Supersmile Extra White Accelerator is a whitening booster meant to be layered on top of Supersmile Professional Whitening Toothpaste. It uses the brand's Calprox formula at triple strength to break down the protein film that holds coffee, tea and wine stains, rather than peroxide or harsh abrasives. Supersmile claims an average of nine shades brighter in 30 days and abrasivity far below typical whitening products, which suits people with sensitive teeth or veneers, bonding and crowns who want gradual whitening. Against peroxide strips and gels it works more slowly and depends on pairing with the toothpaste, but it avoids the sensitivity those often cause.

    What reviewers say

    Raters give it high marks, with many reporting visibly whiter teeth over several weeks and no sensitivity. Complaints center on the dependence on Supersmile toothpaste and the patience the routine requires.

    What people mention
    • SensitivityPraisedUsers with sensitive teeth say it whitens without the zing of peroxide products.
    • Whitening resultsPraisedMany report visibly brighter teeth after several weeks of twice-daily use.
    • Enamel safetyPraisedReviewers with veneers and bonding say it treats their dental work gently.
    • Toothpaste pairingCriticisedSeveral note it only works well alongside Supersmile toothpaste, so it is not a standalone product.

    About the Extra White Accelerator

    Extra White Accelerator is a whitening enhancer made to be used with Supersmile Professional Whitening Toothpaste. It uses Supersmile's Calprox® formula, with triple the Calprox®, and contains no peroxide or harsh abrasives.

    The formula gently dissolves the protein pellicle layer, which traps stains from coffee, tea, wine, berries and everyday buildup. Once that layer is lifted, stains release more easily. It is enamel-safe and maintains the integrity of veneers, bonding and other dental work.

    To use it, put a pearl-sized drop of Supersmile Whitening Toothpaste on a dry toothbrush. Add a pearl-sized drop of the accelerator on top. Brush for two minutes, twice daily. Fluoride, calcium and phosphates add strength and help protect against cavities.

    Questions and answers

    Does it work without Supersmile toothpaste?
    Supersmile designed it as a booster for its Professional Whitening Toothpaste, and the shade claims assume the two are used together. On its own it has little to activate against stains.
    Is it safe for veneers and bonding?
    Supersmile states it is peroxide-free and non-abrasive enough for veneers, bonding, crowns and other dental work. It is not a substitute for a dentist's advice on restorations.
    How long until I see results?
    The brand's studies point to an average of nine shades over 30 days with twice-daily use. Most users notice gradual change over weeks rather than days.
    How do I use it?
    Put a pearl-sized drop of toothpaste on a dry brush, add a pearl-sized drop of accelerator on top, and brush for two minutes twice a day.
    Will it cause sensitivity?
    It contains no peroxide and is formulated to avoid the sensitivity associated with whitening strips and gels. Users with sensitive teeth commonly report none.
    Does it help with intrinsic stains?
    It targets surface stains held in the protein film, so coffee, tea and wine marks respond best. Stains inside the tooth, such as from tetracycline, are unlikely to change.
    Where is the Extra White Accelerator cheapest?
    At supersmile, for $60.00, as of our latest check.
    What do buyers say about the Extra White Accelerator?
    Rated 4.6 out of 5 from 1,003 ratings.
