How is your overall dental health? It's important to have a complete oral exam before beginning any whitening treatment to make sure you are cavity-free and don't have any underlying problems like gum disease. Teeth whitening can aggravate these issues and cause further damage and pain.
Do you have extra-sensitive teeth and gums? If you do, a consultation with your dentist before beginning any professional treatment can steer you in the right direction. You may even be better off with a professional whitening treatment -- pain alleviation has come a long way in the professional setting. Many say that it also helps to use a toothpaste for sensitive teeth for several weeks before, during and after treatment.
Are you realistic about the results you desire? Results vary from one person to the next and often are based on the starting condition of your teeth. In compiling this report, we saw many complaints from people who started with bad staining issues and were disappointed that they weren't dazzling white at the end of 14 or 20 days. If you have normal yellowing or discoloration from wine or coffee, most whitening products will give you a nice improvement in color. If you have dark stains or simply have a yellow hue to your teeth, don't expect miracles. If you don't get the results you want from an over-the-counter product, consult with your dental professional to see if an in-office product or procedure would be more effective.
Do you want to maintain that sparkle? Dental professionals agree: teeth whitening shouldn't just be limited to once every six months to a year. While that will brighten your smile for the short term, for the best long term results you should also use a whitening toothpaste and rinse, as well as flossing regularly. These products don't even all have to be from the same manufacturer, feel free to mix and match as you find products that suit you.
Teeth whiteners are an unregulated product. Unlike many oral care products, teeth whiteners are not regulated by either the FDA or the ADA, nor does the ADA give its Seal of Approval for teeth whiteners. However, the most well-known makers of teeth whitening products, Crest, Colgate, Rembrandt, etc. use ingredients that are accepted as safe when used properly. This is why it's best to stick with the name brands when purchasing teeth whitening products. While you may not know the exact percentages of ingredients, you can be sure that all ingredients are safe to use for the vast majority of people.
Look for reviews from "verified purchasers." There are plenty of teeth whiteners on the market and those that get the most glowing reviews are made by companies that you've never heard of. Take a close look at those reviews before clicking on "buy now." Many do not indicate if the product was actually purchased by that person (something most retail websites note), and/or, if you look at the very end of each review, you'll find that the reviewer was given a free product in exchange for their "unbiased" review -- we found a few products with reviews that consisted only of that type of exchange. Don't buy that positive review and don't buy the product -- opt for a well-known manufacturer instead and be assured that their satisfaction guarantee will actually be honored -- and if you have any other issues you have some recourse. Again, speaking to your dentist to get his or her take on a product is an excellent idea.
