Teeth whitening has become a common process. Affordable tooth whitening products are widely available at drug and grocery stores. With an increasing number of people whitening their teeth at home, it is easy to wonder if the process is safe. However, teeth whitening is remarkably safe.
Many people may have gotten the wrong idea because of how older whitening formulas used to work. Remember "Pearl Drops" for smokers? It used harsh abrasives that literally scoured away the stains and took off a little enamel in the bargain! (Read my article featured below to learn why stripping enamel makes your teeth more yellow, not whiter!)
Now, it takes a lot of time for intrinsic stain to form because the tubes in the "honeycomb" tend to be "plugged up" with organic matter. If they were wide open, your teeth would be terribly sensitive to temperature changes, especially cold. In order to work, bleaching agents need to remove the plugs so they can penetrate to the inner layer of your teeth, where they work their magic. The active ingredient loses effectiveness quickly, so no need to worry that you're trapping harmful chemicals inside. After some time (usually a couple of weeks), the plugs return.
If you decide to use a more aggressive whitener, begin using toothpaste made for sensitive teeth a week before you begin the whitening toothpaste. These toothpastes are very effective at reducing sensitivity in the teeth and can make the tooth whitening experience pain-free. It does take some time to get the best results from this toothpaste, so even if you experience some initial discomfort, continue to use the toothpaste.
Fair-skinned or light-sensitive people are exposed even to greater risk, said lead author Ellen Bruzell from the Nordic Institute of Dental Materials. Besides, dentists found that teeth whitening damaged teeth, resulting in grooves on the enamel. It makes teeth more vulnerable to stress when we chew food. Tooth bleaching is one of the most popular cosmetic dental procedures today. The treatment uses bleaching agents – hydrogen peroxide as a rule – to remove stains on enamel from tea, coffee, red wine and cigarettes. UV-light is more effective to activate the oxidation process meaning better bleaching results, but dentists say the treatment brings no benefit to teeth health.
Regardless of the type of teeth whitening products that you choose, you can rest assured in knowing that they are harmless. Any pain that you experience from the tooth whitening process is temporary and will not result in lasting harm. Although the tooth whitening process is harmless, most dental professionals recommend that you limit the procedures to once or twice a year.
