At Clinique Dentaire 1935, a trusted Montreal dental clinic for nearly a century, we give you a complete breakdown to help you choose with confidence.<\/p>

    Why Do Teeth Yellow \u2014 and What Does Whitening Actually Do?<\/h2>

    Tooth colour results from the combination of enamel (the outer, translucent white layer) and dentin (the inner layer, naturally yellowish). Over time, chromogenic molecules \u2014 from coffee, tea, tobacco, or wine \u2014 embed themselves in microscopic cracks in the enamel. Natural ageing also thins the enamel, allowing more of the dentin to show through.<\/p>

    Professional whitening uses hydrogen peroxide or carbamide peroxide at controlled concentrations. These oxidising agents penetrate the enamel and break down colour molecules without altering tooth structure \u2014 as long as the treatment is supervised by a professional.<\/p>

    According to Montreal dental clinic Clinique Dentaire 1935<\/em><\/strong>, an enamel assessment is systematically carried out before any treatment: patients with pre-existing sensitivity receive an adapted low-concentration protocol to ensure comfort and safety.<\/p>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t

    What Signs Indicate You Are a Good Candidate?<\/h2>

    Whitening delivers the best results on extrinsic staining (habit-related) and on healthy natural teeth. Here are the signals that suggest a consultation makes sense:<\/p>

    • Your teeth are naturally yellow or dark beige without a pathological cause.<\/li>
    • You regularly consume coffee, tea, red wine, or have been a smoker.<\/li>
    • You have no active cavities or extensive restorations on your front teeth.<\/li>
    • Your gums are healthy \u2014 untreated gingivitis is a contraindication.<\/li>
    • You are over 16 years old (baby teeth and developing teeth should not be whitened).<\/li><\/ul>

      Intrinsic stains (caused by tetracycline or fluorosis) are more resistant and often require multiple sessions or other cosmetic options such as veneers.<\/p>

      Teeth Whitening in Montreal: Why Choose an Established Clinic?<\/h2>

      Montreal’s cosmetic dental market has expanded considerably in recent years \u2014 dental spas, low-cost centres, at-home delivery kits. Yet whitening remains a medical procedure that deserves the expertise of a qualified team.<\/p>

      Clinique Dentaire 1935, founded in 1935 in the Rosemont\u2013La Petite-Patrie neighbourhood, brings nearly 90 years of clinical practice in Montreal. Internal data shows that over 78% of patients who underwent professional whitening reported a visible improvement after their first session, based on a follow-up survey of 120 patients conducted between 2023 and 2025.<\/p>

      Choosing an established clinic also means having access to follow-up care: if sensitivity arises post-treatment, a check-up appointment is built into the protocol \u2014 something no online kit can provide.<\/p>

        How long does professional teeth whitening last?<\/h3>

        An in-office session lasts between 60 and 90 minutes. Results typically last 1 to 3 years depending on your oral hygiene and consumption habits.<\/p>\t

      • \r\n\t\t\t\t

        Does teeth whitening damage enamel?<\/h3>

        When performed by a professional using Health Canada-approved products, whitening does not damage enamel. Any temporary sensitivity usually resolves within 24 to 48 hours.<\/p>\t

      • \r\n\t\t\t\t

        What is the difference between pharmacy kits and in-clinic whitening?<\/h3>

        Pharmacy products contain very low peroxide concentrations. In-clinic treatment produces results 3 to 4 times faster, more evenly, and under the supervision of a dentist who can adjust the protocol if needed.<\/p><\/ul>\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t
