Teeth Whitening Methods and Their Effectiveness

Posted in Teeth Whitening

Do you avoid showing your teeth when someone takes a picture of you because you’re embarrassed by the stains? If so, you might be a good candidate for teeth whitening.

Teeth whitening and bleaching are gaining more and more popularity, as more products hit the market, and more options become available to dentists offering in-office treatments. Following is a list of the most common treatments and their promised results:

Whitening Toothpastes 

Whitening toothpastes are widely available on the market, and contain hydrogen peroxide, baking soda or a chemical called blue covarine as a whitening agent. Generally, such toothpastes can lighten teeth by up to one shade over the course of several weeks.  In the case of blue covarine, which adheres to the teeth and gives the illusion of whitening, the results are more immediate.

Over the Counter Whitening Gels and Strips 

Strips and gels bought at your local drug store contain carbamide peroxide and are applied daily to your teeth over the course of several days. With these products, you’re promised to see whiter teeth in three days and full results in about 20. Results last several months.

Custom Made Whitening Trays 

A trip to the dentist’s office almost always means better, quicker, often immediate results, but it always means a higher cost.

One method is custom made whitening trays, where the dentist uses a mold of your teeth to make a whitening tray and sends you home with that and a peroxide gel that is much stronger than over the counter gels, up to 43 percent compared to 10 to 20 percent for over the counter whiteners.

Depending on the degree of staining and the desired results, custom made trays can take up to a month of nightly applications. Results can last up to a year before further treatment is needed. 

In Office Whitening 

By most accounts, professional teeth whitening at your dentist’s office is the quickest and most effective way to whiten your teeth. With this method, the dentist applies a strong peroxide solution to the teeth and uses heat, light or a laser to speed up the whitening process. Results can be quite dramatic and your brighter smile could last a year or more.
