All whiteners contain carbamide peroxide which is a nuclear contaminant. The short term safety has been established. It hasn't been in common use long enough to establish the long term safety.
More often than not, teeth whitening serves as an adequate solution to discoloration. However, the effectiveness of teeth whitening can vary, depending on the individual. Also, whitening procedures can cause temporary tooth sensitivity, which varies in intensity from person to person.
Occasionally tooth discoloration is so severe that whitening alone cannot fully treat the problem. In these situations, veneers might be a better option. Your dentist can advise you about this.
The advantage of having your teeth whitened in the dental office is that this approach is fast and produces immediate improvement. Typically, your teeth can be whitened by several shades within 45 minutes, dramatically improving your appearance in the shortest possible time.
In some types of in-office whitening, application of the whitening gel occurs in three sessions over the course of the visit. A special lamp is used to activate the whitening gel and speed up the whitening process. Once the gel is activated, it remains on the teeth for 15-20 minutes until the next application.

Disadvantages of in-office teeth whitening include cost and greater incidence of temporary tooth sensitivity. Since in-office, one-time regimens use potent whitening agents, there’s more potential for temporary sensitivity.
The most effective at-home whitening systems use a prescription-strength gel kit your dentist provides. Most kits contain mouth trays that you fill with the whitening gel and place over your teeth for varying times, from a few minutes to overnight.
Advantages of at-home products include cost and the ability to re-treat as needed. Although it takes longer, many people find that eventually the results of at-home whitening are on par with in-office procedures.
While the dentist-prescribed at-home whitening systems are more effective than other at-home options, you may choose a less expensive over-the-counter teeth whitening kit. These kits may contain whitening gel and application trays, or whitening strips that you place on the surface of your teeth.
Your chances of success with any of these are about the same and vary with individuals. Just pick a type that you think you can manage the application process and see what you get. The trays are a little more effective, but the strips can produce nice results. If you have your teeth cleaned first that helps.
There are tooth whitening toothpastes. Often these get good results.

Advantages & Disadvantages of Teeth Whitening
Pros and Cons of Teeth Whitening
Advantages:
People typically have their teeth whitened to improve their appearance. Whiter teeth are associated with beauty and a healthier lifestyle. When people have a brighter smile, they tend to smile more often and are less self-conscious.
In addition, a whiter smile tends to minimize the appearance of facial wrinkles, giving way to a more youthful and energetic appearance.
Finally, a whiter smile gives people to whom you are speaking a place to focus on and gives you a friendlier appearance.

Disadvantages:
Although bleaching is very effective, there can be short term disadvantages, such as sore gums or teeth from the bleach. This disappears when bleach use is discontinued. Some individuals are more chemically sensitive. If you are one of them, inform your cosmetic dentist so that you can be tested for sensitivity to the solution.

Research indicates that bleaching is completely effective in more than 78% of people. In cases of serious teeth discoloration, bleaching may not be the best choice. Veneers or crowns may be the superior choice. Bleaching is usually the first solution to try due to its lower cost.

Some people experience discomfort from wearing the mouth tray. This typically goes away in short order, but if you suspect that there is a problem with the fit of your mouth tray, call your dentist's office. They can often make small adjustments that will minimize or eliminate the problem.

Want Brighter Teeth? Just Make Sure You Know The Pros and Cons of Tray Based Teeth Whitening
By Tim Gorman
Today, teeth whitening is one of the most sought after procedures to improve appearance. Many people do put in a considerable amount of time and effort in finding the most effective teeth whitening procedure for themselve.

If you want to whiten your teeth, you can either go to a dentist and have him or her perform a teeth whitening procedure on you, or you can buy a mouthpiece or tray with teeth whitening chemical and use it at home.

Typically, a tray is a rubber or plastic based mouthpiece. You boil a tray and place it in your mouth so that it gets molded into the shape of your mouth. When the mouthpiece cools and settles around your teeth, it is now ready for you to use. You can then place the teeth whitening chemicals inside the tray and use it.

Teeth Whitening Treatments Pros and Cons

White teeth can give your confidence a boost, you are less self conscious of smiling and it makes you feel more attractive. Everyone wants a nice bright smile. White teeth are associated with youth and attractiveness and have become a desirable feature for many. A recent estimate found that one third off all Americans have tried or have inquired about teeth whitening treatments.

There are two main methods of whitening teeth. The first process involves applying a high concentration of oxidizing agent for only a short period of time. The process is usually carried out at a dentists because of this risk. You get quick results with this method but it can result in burns to the soft tissues if the procedure is not carried out properly. The procedure can often achieve between four to six shades of whitening after only one 40 minute treatment. Cost can vary between $300 and $1000.

The second method involves using a much lower concentration of the oxidizing agent. This is an at-home teeth whitening procedure and is usually more popular because it is less expensive and more convenient than the first process. Costs for these type of products are rarely more than about $35. The agent is held against the teeth using a mouth guard for several hours each day over a period of anything between 5 and 14 days. If you are going to be using the method than you should follow the treatment instructions carefully. There are many products available for this method, most of which can now be bought over the counter.

As a person get older teeth tend to become darker in color. This is a result of many factors including the changes in the mineral structure of the teeth and staining due to tobacco and foodstuffs.

Teeth whitening procedures can be quite effective but there are advantages and disadvantages with each procedure which need to be weighed up before undergoing treatment. The actual teeth whitening procedure will use a chemical like hydrogen peroxide or carbamide peroxide (the oxidizing agent) to lighten the shade of the teeth by bleaching and removing discoloration. The oxidizing agent can usual bleach stains that reside in both the enamel and dentine layers of the teeth.

Bleaching or whitening can produce some pretty dramatic improvements for those with stained teeth. It should be remembered however that not all stains respond to bleaching and that white spots (decalcifications) can become more noticeable. An effect called Rebound which is teeth losing the bleached effect over a period of a month or so has been noted in some studies on Teeth whitening. In should also be noted that some over the counter American teeth whitening products have been banned in Europe over health concerns.

Used sensibly teeth whitening products can give you the smile you always wanted. But before deciding what procedure and products you want to use you should carefully consider the pros and cons of the treatment. Hopefully this article about teeth whitening has given you the basics to make an informed choice.

Recently, efforts have been made to accelerate the bleaching process by the use of light. Studies have shown varying results as to the efficacy of light-activated bleaching.

Side effects of tooth bleaching include chemical burns (if a high-concentration oxidizing agent contacts unprotected tissues, which may bleach or discolor mucous membranes), sensitive teeth, and overbleaching (known in the profession as "fridge-door teeth"). Rebound, or teeth losing the bleached effect and darkening, is also an issue, with some studies showing the rebound effect over 30 days. A recent study by Kugel et al has shown that as much as 4 shades of lightness can be lost over 30 days with light-activated/office bleaching.

You have several options here, the first and most obvious (least expensive too!) is to just be thorough in brushing your teeth. Not missing days, and going for regular dentist appointments.

If this doesn't work, there are over-the-counter teeth whiteners. Beware of some of these! A lot of these are scams so go for a product whose brand name you know and trust.

If none of these methods work, there is always cosmetic surgery. I definetly DO NOT recommend this route unless you have very serious teeth problems.

the safest way is natural tooth whitening agent like strawberries. Also many tooth paste now contain whitening chemicals.

I would use white strips

Depending on whether your teeth are sensitive or not, there are many different options.

If you have no sensitivity, then you could try Crest White strips, they are very effective and easy to use.. they do show results very quickly but you have to be careful not to leave the strips on for longer than recommended because it could cause your enamel to strip away and you may need a root canal. That's very unlikely but I'm just saying...

And if you do have sensitive teeth than try ZOOM whitening.. I got it done by my dentist and it's basically just sitting in a chair with special gel on your teeth and they shine a special light on it and your teeth come out a lot whiter!!! ZOOM allows you to get immediate results, but is more costly than just using white strips. Also, your dentist provides you with retainer-like trays and extra ZOOM gel in case you want to touch it up later on... The only thing about ZOOM is that there's always a chance they will get stained again, which would be a waste of money so if you want white teeth ...just make sure you can maintain them!

i've tried many different things but they are all just temporary. so i try to schedule more dentist appointments and brush my teeth after every meal. i also brush at night and in the morning.

Yes there are varouis ways of whitening teeth but I have found that Baking Soda and peroxide is the best. Arm& Hammer Advanced white toothpaste is the best you see results the fastest. Take my advice and try it. It's like $3.00 at your local Dollar Store.
Wish you best of luck. Lakeisha from AL

I find baking soda and peroxide to be the most effective and the cost is underￂﾣ5. The only disadvatage being tooth sensitivity increases and can be painful so go easy until you know your limits!!! Also read that these can strip enamel so dont over do it! Pearl drops are also an excellent alternative and can be used daily as normal toothpaste. Others worth a try are; Arm and hammer whitening and Beverly hills whitening.
Good luck!
