Want a brighter smile?
When it comes to tooth-whitening, you've got two options: in-office-based teeth bleaching, or at-home care. Both tooth-whitening options use peroxide-based bleaching agents. At-home systems contain from 3% to 20% peroxide (carbamide or hydrogen peroxides). In-office systems contain from 15% to 43% peroxide.
Generally, the longer you keep a stronger solution on your teeth, the whiter your teeth become. However, the higher the percentage of peroxide in the whitening solution, the shorter it should be applied to the teeth. Keeping the gel on longer will dehydrate the tooth and increase tooth sensitivity.
In-Office Tooth Whitening
Teeth whitening done by your dentist can get teeth brighter faster. The bleaching solution is usually much stronger than at-home kits. Also, heat, light, or a combination of the two may be used to speed and intensify the whitening process.
The most dramatic results (teeth that generally get three to eight shades brighter) usually take several 30 to 60-minute in-office visits. Here at Glenashton Dental Centre, we use the technique that can be done in a single 2-hour appointment, known as Zoom.
The Zoom Chairside Whitening System is a scientifically advanced tooth whitening procedure. It's safe, effective and fast. In only one office visit, your teeth will become dramatically whiter. Zoom Chairside Whitening is ideal for anyone looking for immediate results. The convenience of Zoom makes it the perfect choice for the busy individual.
At-Home Teeth Bleaching Options
There are many choices for bleaching teeth at home, the most common include:
- Tooth whitening strips and gels. Applied directly to the teeth with a brush or a thin strip, these peroxide-based tooth bleaching products usually need to be applied once or twice a day for 10 to 14 days. Results last four or more months and may cost from $10 to $55.
- Tooth whitening toothpastes. Because they're mildly abrasive, every toothpaste helps remove stains from teeth. Whitening toothpastes, however, also contain chemicals or polishing agents that help scrub stains from teeth without the aid of a bleaching agent. Tooth-whitening toothpastes are relatively inexpensive and brighten teeth by about one shade. Some whitening toothpastes contain peroxides, but they aren't left on the teeth long enough to have a whitening benefit.
- Tray-based tooth bleaching systems. Like the NiteWhite System we offer here at Glenashton Dental Centre. With this teeth whitening option, a custom fitted mouth guard-like tray is filled with a peroxide-based bleaching gel or paste and placed over the teeth for one to several hours a day for up to two weeks.
There are pros and cons to each option, but before you try at-home tooth-bleaching kits, be sure to talk to your dentist. Not everyone will see good results. Bleaching will not whiten porcelain crowns or composite tooth-colored bondings.
Why You Should Talk to Your Dentist
Tooth bleaching can make teeth temporarily sensitive -- or be uncomfortable for people who already have sensitive teeth. When used incorrectly, home kits can also lead to burned -- even temporarily bleached -- gums.
Tooth-whitening works best for people with yellow teeth and is less effective for people with brown teeth. If your teeth are gray or purple, tooth bleaching probably won't work at all.
To be sure tooth-whitening is worth your time and money, book an appointment with Glenashton Dental Centre to talk to a dentist or hygienst before you use any type of tooth whitening kit.
