Teeth Whitening: How Effective is it?

Posted on April 22, 2009 by Kate

Because of the variety of teeth staining foods, beverages, and cigarettes on the market, many people are turning to teeth whitening products. Companies have now developed methods that are safe and efficient. There are a number of whitening products available to consumers. When choosing a product, it is important to understand their effectiveness.

Teeth whitening works by removing materials and stains from the enamel. It is not permanent but certain products are more effective than others. The two main methods are over the counter products and professional.

Over The Counter Products
Whitening strips: These strips are coated with a thin layer peroxide gel. They are normally applied for 30 minutes twice a day for two weeks. You will see results in only a few days but sometimes it can be uneven. . A package of whitening strips usually contains both upper and lower teeth strips. The number of whitening strips depends on the treatment period. The length of treatment usually depends on the concentration of peroxide in the strips. Whitening strips are convenient to use. The price varies from $10 and $50 for a package of strips. The most popular and most effective strips on the market are the Crest Whitestrips.

Whitening toothpastes: These products whiten by polishing or using chemicals. They tend not to be as effective as products that contain peroxide. They are often used after a bleaching procedure to maintain whitening.

Kits: Most kits include a whitening gel that is placed in mouthpieces that fit over your teeth. The whitening time can vary depending on the kit used. The inexpensive kits are less effective. A good quality kit that gives great results can cost around $500 – $800 dollars. Effective kits will have the American Dental Association seal of approval.

Professional
The most effective and safest method is performed by a dentist. A dentist will assess whether you need a cosmetic procedure or if over the counter methods are sufficient. Problems occurring with a professional whitening method are rare.

Laser: This whitening procedure is performed in a dental office. Laser has become very popular because results are immediate. The procedure begins with cleaning the patient’s teeth. A special gel is then applied to the teeth. This gel contains a strong bleaching agent. After the whitening gel has been applied, the dentist uses a special laser light, allowing for better gel penetration through the enamel. The entire procedure lasts about an hour. Laser teeth whitening delivers better and faster results compared to other teeth whitening products. Depending on the condition of the patient’s teeth, the treatment can whiten teeth up to 8 shades.

Expect to pay anywhere from several hundred dollars to several thousands for a complete laser teeth whitening treatment. Price depends on how much whitening is needed. Benefits of laser treatment include immediate results, greater safety and more even results

Although the procedures are very effective, the lasting effect depends on the product and method you use. The least expensive procedure usually results in less whitening. Some methods may leave patients with sore gums, but it does not last long. . As well, crowns, bridges, bonding, and fillings will return to their original coloring.

If you have questions about the effectiveness of whitening products, or the affects they have on your own teeth, you should speak with your dentist. A build up of stains can be quite unattractive and cause people to feel insecure about their appearance. Whitening your teeth will leave you with a brighter and shinier smile.
