Teeth whitening kits allow you to achieve whiter teeth at home. Many types of teeth whitening kits are available to meet your needs.
What to Know Before Buying Teeth Whitening Kits
It's important to remember that teeth whitening kits don't change the color of dentures, crowns, or fillings. The products are designed to match the natural tooth color as closely as possible.
Realistic Expectations for Teeth Whitening Kits
Keep your expectations for teeth whitening kits realistic. Teeth stains have many causes, and tooth discoloration from medications such as antihistamines or tetracyclines may not respond as dramatically to treatment with teeth whitening kits as teeth stains from coffee, tea, wine, or cola. In addition, keep in mind that most teeth whitening kits will not have any effect on tooth-colored fillings that become stained over time. Your best bet may be to have the fillings replaced, and then use teeth whitening kits to improve the appearance of your natural teeth.
Where to Buy Teeth Whitening Kits
You can buy teeth whitening kits in grocery stores, drug stores, or online. If you're deciding between two types of kits, try one first and then try another if you aren't satisfied with the results. For example, if you have teeth sensitive to whitening, choose from the teeth whitening kits with lower concentrations of whitening product. If you aren't getting the results you want, and you don't notice a problem with tooth sensitivity, try one of the teeth whitening kits with a slightly higher concentration of whitening product.
How Teeth Whitening Kits Work
Teeth stains occur when staining agents in food, drink, or tobacco smoke work their way through the porous tooth enamel over time, forming stains that can't be erased by brushing alone. Teeth whitening kits contain chemicals, usually hydrogen peroxide, that penetrate the stains without damaging the structure of the tooth, although some people do report temporary tooth sensitivity while using teeth whitening kits. Most teeth whitening kits use either hydrogen peroxide or carbamide peroxide.
