Teeth Whitening Strips For The Beautiful Smile

Whether you're a heavy smoker, you drink three cups of coffee each day or you've simply noticed that your teeth are becoming faded and yellow with age, you may be wondering how to regain the bright white smile you once had. While there are several whitening methods available, whitening trays are popular options that can create noticeable improvements for people of all ages. Keep reading to learn exactly how whitening trays work and what facts you should know if you plan on using electric toothbrush.

How Do Teeth Whitening Trays Work?
A teeth whitening tray system consists of trays that you place over your teeth, much like you would a mouth guard, along with a whitening gel that fights surface stains as well as deeper stains. There are various types of tray whitening systems, from those that are only applied at a dentist's office to those that are completely administered at home, along with several varieties that require both office visits and home applications.
All of these systems involve placing a whitening gel or solution in the trays and fitting the trays over your teeth for anywhere from under an hour to overnight. This procedure typically needs to be repeated a few times before teeth become noticeably whiter. An in-office teeth whitening tray application may require you to schedule several dentist visits, while an at-home system may be used once or twice each day for one to two weeks, depending on the individual product instructions and recommendations.
The key whitening ingredient in whitening strips is peroxide. All teeth bleaching products like whitening gels, whitening pens, and whitening strips contain peroxide in one of two possible forms. Carbamide peroxide is the most commonly used in gels and can be found in some more effective whitening toothpastes and wireless curing light as well, while hydrogen peroxide is typically used in whitening strips and whitening pens.
Carbamide peroxide breaks down into hydrogen peroxide, meaning this form of peroxide is less effective at whitening than an equal concentration of hydrogen peroxide. In fact carbamide peroxide is around 1/3 the strength of the same concentration of hydrogen peroxide. Despite this carbamide is still an effective whitening agent and is often used in gels because it can be safer to handle than high concentrations of hydrogen peroxide.
Hydrogen peroxide is an oxidizer, meaning it breaks down itself into oxygen and water. The concentrated oxygen penetrating through the pores of your enamel into your teeth is what breaks apart the stains that discolor you teeth. These stain pigments are torn apart at a molecular level by the oxygen. This is why peroxide whitening gels and strips are more effective at whitening teeth than abrasives like baking soda or most whitening toothpastes, which don't include peroxide.
Gum irritation can be limited by carefully applying the strips so that they do not come into contact with your gums. Depending on the brand of strips and their size, this may be difficult to avoid.
You can also decrease the time you wear the whitening strips to decrease the risk of sensitivity and gum irritation, however this will of course decrease the effectiveness of the whitening process. Despite this you can still get great whitening results by wearing the strips only on every other day and using a high quality whitening toothpaste in conjunction with them.
