Teeth whitening is becoming the most common cosmetic service provided by dentists as well as becoming popular to accomplish at home. There are a growing number of over-the-counter “at-home” products to choose from.
We all know about teeth whitening strips, kits, trays and toothpaste, however pens are becoming more and more popular.
How do they work? Just like other systems, teeth whitening pens contain carbamide or hydrogen peroxide. It depends on what brand you’re using, but you usually rotate the bottom of the pen, to push out a small amount of whitening gel onto the brush. Then, you apply a thin layer of whitener onto your teeth and allow a couple of minutes to dry. That’s all there is to it.
The pens are not as strong as trays or strips. Concentration of whitening agents is generally weaker and the treatment cycle is too short to affect a drastic change. Many manufacturers promise up to eight shades of whiteness, but you can usually lighten your teeth up a few shades (about three, or so) by using pens.
Studies confirm that whitening at home is safe and does not cause any damage to the enamel on the tooth. Higher concentrations of hydrogen peroxide and carbamide, usually available at the dentists may weaken the enamel.
The average price of teeth bleaching pens is about $12 – $80. One pen is for 30-day use. Despite the offers you see online – there are no free teeth whitening products, just trial offers.
