What is the best one?
--------------------
Over-the-counter teeth whitening toothpastes are the most popular whitening products around, but the truth is "you get out of it, what you put into it." The success of any teeth whitening technology lies primarily in the amount of time the teeth are in contact with a bleaching agent - and the concentration of the bleaching agent being used. Since toothpastes contain a very low concentration of bleach and remain on the teeth for mere minutes - or even seconds - they deliver only a small degree of visible change under ideal circumstances. What's available in the market? Today, many oral care brands have their own versions of whitening toothpastes, such as: Crest Extra Whitening toothpaste, Rembrandt Whitening Toothpaste and Colgate Whitening Toothpaste. The companies that manufacture these whitening pastes do not make false claims, and consequently, promise only modest whitening results. How do whitening toothpastes work? Almost all the whitening toothpastes work on the same principle. They use hydrogen peroxide or other whitening agents in very small quantities to gently remove surface stains caused by tea, coffee, wine, etc. Results Some dentists believe that teeth whitening toothpastes are a complete waste of time and money and aren't any better at whitening teeth than ordinary toothpastes. Other dentists believe that whitening toothpastes can help improve the color of teeth, albeit to a very small degree. However, in some cases, people do experience considerable improvement in their tooth color, largely due to individual dental characteristics. Overall, however, the whitening results obtained from teeth whitening toothpastes are almost negligible. Do-It-Yourself Over the Counter Whitening If you're looking for more dramatic results than those delivered by teeth whitening toothpastes, then you're apt to consider Over-The-Counter Whitening, such as Crest Whitestrips Advanced Seal. These products feature mouth trays, whitening strips or paint-on applications - and are widely available at grocery, drug and discount stores nationwide. How do they work? While more expensive than teeth whitening toothpastes, these inexpensive whitening options (compared to dentist-prescribed whitening solutions) typically involve the use of a low-concentration bleaching gel with detailed, daily use instructions that you follow at home. You'll wear the trays, strips or painted-on bleach for up to 60 minutes a day (in two or more individual applications) and for the suggested period of time - 1-2 weeks depending on the product. Results Most people with simple surface stains will experience a multi-shade change, primarily on their front teeth. While the technology of at-home, over-the-counter whitening is designed for ease-of-use; most people will find it very difficult to follow the directions exactly, particularly with regard to reaching and whitening the back teeth. Kiosk Whitening Kiosk whitening is a blend of do-it-yourself and "professional" whitening techniques that's currently under intense criticism from both many state dental boards and the American Dental Association. You'll find whitening kiosks in malls all over the country and they claim to offer "professional results" at a fraction of the cost of in-office bleaching techniques. How do they work? Kiosk whitening is "legal" because you do most of the work yourself. You'll first be given the materials to make an impression of your own teeth. When the trays are ready, you'll then fill them with a peroxide bleaching gel (less concentrated than the strengths prescribed by dentists). You'll then insert the trays into your mouth, followed by application of the accelerator lights by the whitening assistant. Results Most kiosk whitening franchises will not make a claim about how much whiter their procedure will make your teeth. Some, however, say that their procedure will work on up to 93% of people. Again, the procedure works best on the best whitening candidates. Concerns Because whitening kiosks aren't staffed by people who've undergone any accredited dental training, there is no real screening involved to eliminate unlikely whitening candidates. So while someone with severe stains may not experience any whitening - someone with cavities, cracked teeth or serious dental disease may actually experience pain, or worse.

Professional Take Home Trays Take-Home Tray Whitening is tooth whitening in a kit that can be used at home, usually under the supervision of a dentist. Dental-supervised tray whitening is very effective and is considered the "gold standard" in its class. How do these kits work? Dentists make a mold of your teeth in the office and then have custom-fitted trays created to fit each arch of your mouth. When you're home, you fill the trays with a peroxide bleaching gel and place them over your teeth. The concen
