What is the Active Ingredient in Teeth Whitening Strips ?


Most teeth whitening strip products in the marketplace contain hydrogen peroxide as the bleaching agent. Due to differences in concentration, or the amount of peroxide in each product, the effect varies. OTC whitening strips contain anywhere from 3% to 10% hydrogen peroxide. Professionally dispensed whitening strips (available only through a dentist) usually contain around 15% hydrogen peroxide. Whitening procedures conducted in dental offices and in teeth whitening centers contain hydrogen peroxide in the range of 15- 38% .

How Do Teeth Whitening Strips Work ?


The peroxide gel on a white strip works to slowly bleach your teeth to a lighter shade. Many whitening strips often come in two different sizes, one size for the upper teeth and one for the lower teeth. By pressing these strips up against your teeth for a tight fit, the gel makes contact with your enamel. Teeth whitening strip products differ in the percentage of peroxide they contain, and thus the usage instructions are different for each type. In general, expect to wear the strips for 30 minutes once to twice a day over the course of one to two weeks. Individuals are strongly encouraged to closely follow any and all instructions included in these OTC whitening strips.

Paint On Teeth Whitening Advantages


Advantages and Disadvantages of Using Paint-On Teeth Whiteners

Despite some disadvantages, there are still instances where paint-on teeth whiteners are the best choice. For instance, if you only need to bleach a couple teeth, a paint-on whitener may be perfect for you. For best results, each patient needs to weigh all of their options and take the advice offered by their dentist.

Disadvantages Of Paint-on Teeth Whitening

There are some disadvantages to paint-on teeth whitening techniques that may be valid reasons for choosing another method. One criticism of this technique is that the whitening agent that is painted on dissolves too quickly for the bleaching agent to break down into free radicals and further break down the staining. It is essential for the whitener to stay on the teeth long enough for this process to complete itself.

A study was performed with two subject groups.: in one group whitening gel was applied and then covered with a polyethylene strip to keep the gel in place (protecting it from saliva, and any other fluids or motion that might dilute or remove the gel). In the second group, the paint-on whitener was left uncovered. The whitening results from the covered gel resulted in significantly improved whitening. [1]

The use of professional whitening trays and OTC strips allows the whitener to stay closer to the teeth for the necessary amount of time resulting in a more effective whitening treatment. These other methods are also more effective at protecting the whiteners from being diluted from fluids in the mouth. Professionally dispensed whitening trays have proven to be a highly effective at-home whitening technique; however, OTC strips have tested at a comparably high level.

Consulting a dentist will help you make the best choice that suits your needs and lifestyle.

Teeth Whitening Strips


Another popular OTC whitening option are teeth whitening strips. There are several types of teeth whitening strips available. The Proctor & Gamble Company was the first to introduce an over the counter teeth whitening product on a broad scale with Crest Whitestrips. Since then many companies have followed suit and now there are numerous teeth whitening products on the market, such as Listerine Teeth Whitening Strips and Rembrandt Whitening Strips.

Teeth Whitening strips are thin pieces of plastic covered with a tooth whitening gel that contain peroxide. By wearing the strips as indicated on the product packaging, the gel comes into contact with the surface of your teeth and works to slowly take away surface stains, and stains in your enamel.

Paint-On Teeth Whitening


In addition to these professional products and procedures, there are a multitude of OTC or over-the-counter teeth whitening options as well. One type of readily accessible teeth whitening product is commonly referred to as paint-on teeth whiteners. Paint-on teeth whiteners can be purchased over-the-counter, and are generally less expensive and less effective than teeth whitening strips or professional options. Paint-on teeth whiteners consist of a gel that is applied to the tooth using a small brush. Colgate Simply White is an example of a paint-on whitener that is intended to be applied twice daily for 30 minutes, while Crest Night Effects® and Colgate Simply White Night® are intended to be applied before bed, and to be left on the teeth overnight. Paint-on teeth whitening gel hardens into a film that coats the treated tooth, and dissolves in the mouth.

Paint-on whiteners can contain either carbamide peroxide or hydrogen peroxide as their primary bleaching ingredient. As with any teeth whitening regimen, it is wise to consult with a dental professional before treating discoloured teeth.
