You've probably seen those ads on Instagram: a blue light-up tray in your mouth to get a Hollywood smile in 20 minutes. LED (Light Emitting Diode) whitening has become the star of cosmetic dentistry.<\/p>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t

\n\t\t\t\t\t
\r\n\t\t\t
\r\n\t\t\tBut let's be clear: light alone doesn't whiten anything at all. It's an accelerator. If you use an LED lamp without the correct medical product, you'll only end up with... illuminated teeth.<\/span>\r\n\t\t<\/span><\/h5>\r\n\t\t<\/div>\t\t\t\t<\/div>\n\t\t

Can your teeth react to LED technology?<\/h4>\t\t\t\t<\/div>\n\t\t\t\t

Some hair dyes (grey, medicated) are completely immune to this treatment. Don't pay for nothing.<\/p>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t

How does LED technology actually work? <\/h4>\t\t\t\t<\/div>\n\t\t\t\t
\n\t\t\t\t\t\t\t\t\t

The principle is scientific: it is about photo-activation<\/b>. Teeth whitening relies on a gel (hydrogen peroxide or carbamide) that opens the pores of the enamel to dislodge stains.<\/p>

The role of the LED lamp (this specific cool blue light) is to act as a catalyst. It excites the molecules in the gel to:<\/p>

  1. Accelerate the chemical reaction:<\/b> What used to take 2 hours now only takes 45 minutes.<\/p><\/li>

  2. Intensify penetration:<\/b> The bleaching agent penetrates deeper, faster.<\/p><\/li><\/ol>

    The trap of home kits:<\/b> The kits sold online contain very weak LED lamps and, most importantly, extremely low-concentration gels (less than 0.1% of peroxide according to European law). The result? You're activating\u2026 water. The effectiveness is practically nil.<\/p>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t

    \n\t\t\t\t\t

    Why does only LED whitening in the office work? <\/h4>\t\t\t\t<\/div>\n\t\t\t\t
    \n\t\t\t\t\t\t\t\t\t

    The difference lies in one number: the concentration. In the dental practice, we are allowed to use much stronger gels (up to 6% or more under strict conditions), because we protect your gums.<\/p>
