Teeth whitening or bleaching is one of the most affordable and least invasive ways of improving your smile. Although the effect fades with time, whitening can make dull and dingy teeth more attractive in short order.
Teeth whitening is also unique among cosmetic dental procedures in that you can do it yourself at home. While professional bleaching solutions are stronger and capable of greater brightness and longevity, you can still achieve good results with a DIY kit.
If you decide to whiten at home, though, there are a few things to keep mind for a desirable and safe outcome. Here are 3 tips for successful DIY teeth whitening.
Follow the directions. It's not a good idea, both for a successful and safe outcome, to stray away from a kit manufacturer's recommended directions. FDA-approved home kits usually contain 10% or less of carbamide peroxide (one of the more common bleaching agents). That may not seem very strong but it's adequate within the recommended time it remains on your teeth to achieve an effective whitening effect. Exceeding those directions could permanently damage your tooth enamel.
Make sure a home kit will work on your staining. Home whitening kits only affect outer staining on tooth enamel. But dental discoloration can also arise from inside a tooth, often because of trauma, tetracycline use, or as a side effect of a root canal treatment. This kind of internal staining requires a special procedure usually performed by an endodontist to reduce it. So, see your dentist first to make sure your teeth are healthy enough for whitening and that a home kit will work for you.
Get your dentist's advice on home kits. There are a number of whitening applications on the market you can choose, so ask your dentist for recommendations. They can also give you some helpful tips on the whitening process to ensure you'll be safe and successful in your efforts.
Here's a couple of other things to remember to enhance your teeth whitening experience: whether you whiten your teeth at home or with the dentist, be sure you continue to care for your teeth with daily brushing and flossing. And, if you limit your consumption of foods and beverages known to stain teeth, you'll help extend the duration of your brighter smile.

Academy Award-winning actress Kathy Bates knows how important it is to present your best face to the world — and one of the most important features of that face is a beaming smile. But there came a point when she noticed something was a little off. “I've always had good teeth, but it seemed to me as I was getting older that they weren't looking as good,” Kathy explained in a recent interview with Dear Doctor magazine.
That's when she decided it was time to take action. Kathy had orthodontic treatment when she was in her fifties, and she keeps her smile bright with tooth whitening treatments. She uses a kit provided by her dentist with a safe, effective whitening solution.
Of course, a bright, healthy smile looks great anywhere — whether you're on the red carpet or “off the grid.” And you don't have to be a Hollywood star to have professional whitening treatments. In fact, teeth whitening is one of the most popular and affordable cosmetic treatments modern dentistry offers.
The basic options for professional teeth whitening include in-office bleaching or take-home kits. Both types of dentist-supervised treatments offer a safe and effective means of getting a brighter smile; the main difference is how long they take to produce results. A single one-hour treatment in the office can make your teeth up to ten shades lighter — a big difference! To get that same lightening with at-home trays, it would take several days. On the plus side, the take-home kit is less expensive, and can achieve the same results in a bit more time.
It's important to note that not all teeth can be whitened with these treatments. Some teeth have intrinsic (internal) stains that aren't affected by external agents like bleaches. Also, teeth that have been restored (with bonding or veneers, for example) generally won't change color. And you can't necessarily whiten your teeth to any degree: Every tooth has a maximum whiteness, and adding more bleach won't lighten it beyond that level. Most people, however, find that teeth whitening treatments produce noticeable and pleasing results.
What about those off-the-shelf kits or in-the-mall kiosks? They might work… or they might not. But one thing's for sure: Without a dentist's supervision, you're on your own. That's the main reason why you should go with a pro if you're considering teeth whitening. We not only ensure that your treatment is safe — we can also give you a realistic idea of what results to expect, and we will make sure that other dental problems aren't keeping you from having a great-looking smile.
How often does Kathy Bates see her dentist for a checkup and cleaning? “I go about every four months,” she noted. “I'm pretty careful about it.” And if you've seen her smile, you can tell that it pays off.

Whether performed in a dental office or using a home kit, teeth whitening applications are quite effective for bleaching exterior (extrinsic) stains on enamel surfaces. But what if your discoloration comes from inside the tooth? In this case, extrinsic teeth whitening won’t work — you’ll need to undergo an “internal bleaching” method, which can only be performed in a dentist's office.
There are a number of causes for “intrinsic” staining, including too much fluoride exposure or tetracycline use during childhood. One of the more common causes, though, occurs from root canal treatments used to remove the remnants of the pulp tissue inside a tooth’s pulp chamber and root canals. Certain cements used during the procedure to help seal in the filling material and leftover blood pigments can cause the tooth to darken over time.
To alleviate this discoloration, we use a bleaching agent, usually sodium perborate mixed with a diluted solution of hydrogen peroxide to achieve a safe, accelerated color change. After determining that the root canal filling is still intact and the bone is healthy, we create a small cavity in the back of the tooth to access the pulp chamber. The chamber is cleaned of any debris or stained material and then thoroughly irrigated. The original root canal filling is then sealed off to prevent leakage from the bleaching agent.
We then place the bleaching agent in the cleaned-out space with a cotton pellet and seal it in with a temporary adhesive. This step is repeated for several days until we achieve the desired shade of white. Once that occurs we then seal the dentin with a more permanent filling and then restore the cavity we created with a composite resin bonded to the enamel and dentin.
If we’re successful in achieving the desired color, intrinsic whitening could help you avoid more costly options like veneers or crowns for an otherwise healthy and attractive tooth. The end result would be the same — a beautiful smile without those unsightly stains.
