Health Is your smile ready to be shown off this summer season? If your teeth are stained or discolored, teeth whitening treatments are available to help brighten your smile for an improved appearance. Today, whitening procedures have effectively restored the smiles of people with stained or discolored teeth. Your East Vancouver dentist offers both in-office and take-home whitening treatments to help improve the appearance of your teeth so that you can smile bigger and brighter all summer long. Why Teeth Whitening? Most of us start out with sparkling white teeth due to their porcelain-like enamel surface. Tooth enamel is .posed of microscopic crystalline rods, which are designed to protect your teeth from the effects of chewing, gnashing, trauma and acid attacks caused by sugar. However, over the years enamel is worn down, which makes it more transparent and permits the yellow color of dentin-the tooth’s core material-to show through. While eating, dentin remains intact while millions of micro-cracks occur in the enamel. These cracks, in addition to the spaces between the crystalline enamel rods, gradually fill up with stains and debris. As a result of this, your teeth will eventually develop a dull, lackluster appearance. With teeth whitening, you can remove the stains and debris, leaving the enamel cracks open and exposed. Some of the cracks are quickly re-mineralized by saliva, while others are filled up again with organic debris. In-Office Whitening If you are searching for significant color change in a short period of time, in-office whitening may be just what you are looking for. In-office whitening involves the carefully controlled use of a relatively high-concentration peroxide gel, applied to the teeth by your dentist or trained technician after your gums have been protected with a paint-on rubber dam. The peroxide with typically remains on your teeth for multiple 15-minute intervals that add up to an hour at most. If you have particularly stubborn stains, you may be asked to return for one or more additional bleaching sessions, or you may even be asked to continue treatment with an at-home whitening kit. Take-Home Whitening Kits Many dentists also offer the option of professionally dispensed take-home whitening kits, as they can produce the best results over the long haul. When used as directed, dentist-dispensed whitening trays and strips can even be more successful than in-office bleaching in the long run. The key reason to at-home whitening success is their ongoing use and the fact that only small amounts of bleach remain within the tooth structure for up to 36 hours. When a new dose of bleach is applied to a tooth that is retaining the previous day’s peroxide, the effect is greater. Even though you can get over-the-counter whiteners without a dentist’s re.mendation, if you over-use them or use them incorrectly, they can harm your tooth enamel and irritate your gum tissue. Over-bleaching can also produce an undesirable bluish hue, chalky whiteness, or uneven results. Supervision by your dentist can help prevent these problems. To ensure the health of your smile, visit your East Vancouver cosmetic dentist before choosing an over-the-counter tooth whitener and beginning the whitening processes. Your dentist can make the best re.mendation based on your individual needs. About the Author: 相关的主题文章:
