Do-it-yourself (DIY) whitening kits are a popular option for restoring a healthy shine to stained and dulled teeth. They're relatively safe and generally live up to their packaging claims.
But a home kit might not always be your best option. Here are 4 reasons why DIY whitening might not be right for you.
You're on the early side of your teen years. Tooth whitening at home is quite popular with teenagers. For older teens it doesn't really pose a dental risk as long as you use the product appropriately (more on that in a moment). However, the immature enamel of younger teens' permanent teeth is still developing and can be vulnerable to damage by whitening processes.
You don't follow instructions well. Not to say you have this particular character quirk — but if you do you may run into trouble with DIY whitening. Home kits are safe if you follow their instructions carefully. If you use them to excess as one 13-year old boy was reported to have done, you could severely (and permanently) erode your teeth's protective enamel.
Your teeth are in need of dental work. Tooth whitening can't fix everything that may be contributing to an unattractive smile. It's always better to have issues like dental disease or chipped teeth addressed first before whitening. And, if your tooth discoloration originates from inside your tooth, a whitening kit won't help — they're only designed for staining on the enamel's outside surface. You'll need a special dental procedure to whiten internal (or intrinsic) tooth staining.
You want to control the amount of brightness. Home kits don't have the level of fine-tuning that a clinical procedure can achieve. While the bleaching agent in a professional whitening solution is much stronger than a home kit, your dentist is trained in techniques that can vary the amount of bleaching, from a softer white to dazzling “Hollywood” bright. And clinical whitening usually takes fewer sessions and may last longer than a home kit.
If you're interested in teeth whitening, see your dentist for a dental examination first before purchasing a DIY kit. Even if you decide to do it yourself, your dentist can give you buying advice for whitening kits, as well as how-to tips.

Bright, naturally white teeth are a key component in a beautiful smile. But the opposite is also true: nothing diminishes an otherwise attractive smile more than stained or discolored teeth.
There is good news, however, about tooth staining: it can be greatly reduced with the right whitening technique. But before taking action we need to first uncover the cause for the staining — whether from the outside or inside of the tooth, or a combination of both.
If it’s an external cause — known as extrinsic staining — our diet is usually the source. Foods and beverages that contain tannins, like red wine, coffee or tea fall in this category, as do foods with pigments called carotenes as found in carrots and oranges. Besides limiting consumption of stain-causing foods and maintaining daily oral hygiene, you can also diminish extrinsic staining with a bleaching application.
There are two basic ways to approach this: with either a professional application at our office or with a home kit purchased at a pharmacy or retail store. Although both types use similar chemicals, the professional application is usually stronger and the whitening effect is obtained quicker and may last longer.
Discoloration can also occur within a tooth, known as intrinsic staining, and for various reasons. It can occur during tooth development, as with childhood overexposure to fluoride or from the antibiotic tetracycline. Poor development of enamel or dentin (the main sources of natural tooth color), tooth decay, root canal treatments or trauma are also common causes of intrinsic discoloration.
There are techniques to reduce the effects of intrinsic staining, such as placing a bleaching agent inside the tooth following a root canal treatment. In some cases, the best approach may be to restore the tooth with a crown or porcelain veneer. The latter choice is a thin layer of dental material that is permanently bonded to the outer, visible portion of the tooth: it’s life-like color and appearance covers the discoloration, effectively renewing the person’s smile.
If you’ve been embarrassed by stained teeth, visit us for a complete examination. We’ll recommend the right course of action to turn your dull smile into a bright, attractive one.

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.

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.

In modern society, a bright, white smile conveys optimal health, youth and sound teeth. However, various influences including age, wear, diet, and lifestyle may prevent you from having and maintaining the glistening smile you long to share with the world. Luckily, there are many safe, inexpensive, and successful treatment options for discolored or stained teeth.
We can perform a “power bleaching” in our office to whiten teeth that are severely stained or discolored. This procedure whitens the external surfaces of the teeth by using a high concentration (35-45%) hydrogen peroxide solution, which is sometimes activated by a specialized light. To prevent irritation of the mouth's soft tissue lining during this procedure, we will isolate your gums and membranes with a rubber dam, a silicone or other effective barrier. Professionally applied in-office power bleaching provides control, speed, and predictability capable of lightening teeth up to ten shades in an hour. Don't try this at home! Our staff will take precautions in the office to avoid side effects and possible tooth sensitivity.
We can also provide you with custom-made, vacuum-formed, plastic bleaching trays for use with a take-home whitening application. In this instance, a gel made from carbamide peroxide (4-7% hydrogen peroxide, safe for home use) is delivered to the tooth surfaces in the bleaching trays. You will need to wear the tray for 30 minutes twice a day, which is a longer process than in-office bleaching. The first subjective signs of whitening will occur after three or four sessions, allowing whitening of up to eight shade units.
Another home-based option, whitening strips, essentially look like band-aids for the teeth. They are capable of lightening teeth by about three shades after being worn directly on the surface of the teeth for 30 minutes twice a day for one week.
If you have always wanted whiter teeth, schedule an appointment so we can determine which of these treatment options would work best for you. For more information on the fundamentals of teeth whitening, read the informative Dear Doctor magazine article “Teeth Whitening: Brighter, Lighter, Whiter...”
