So how do you get this noticeable difference? The systems that you can use at home give your teeth back their old color. Most people have discolored teeth because of the things they have consumed in their life. The teeth are stained and they need constant attention for the stains to go away. Teeth whitening systems go to work on the stains and as those go away, the white is allowed to shine through. First you will see just a small bit of progress and then it will gradually get to the point where you have moved many shades. This is important to keep in mind as you continue use.

How long will it take to see a noticeable difference? Most of the time, you can start to see some changes within a week, if not sooner. That means that after using it for only a few days, you should look in the mirror and look at pictures to check on the results. After using it for a few weeks, you will have moved more than a few shades in the right direction. In all likelihood, it will take only a few weeks to get to a place where you are happy.

Maybe you are considering teeth whitening treatment because you are re-entering the dating world, trying to improve your chances of landing your next job or just desiring the personal satisfaction of having stunningly beautiful, white teeth.

Well, no matter your reasons, you do not have to endure repeated one hour "chairside" bleaching visits at your dentist's office. There are other options to quickly remove the yellowish or brown hue from your teeth. The best part is that you can use these products at home.

Of course, you could try tooth whitening toothpaste which contains special polishing chemicals. The chemicals effectively remove the stains on your enamel. Also, these whitening toothpaste products remove surface stains.

Unfortunately, they will not remove the yellowish stains fast. In addition, since the whitening toothpaste products do not contain bleach, they will not change the natural color of your enamel. In other words, if your teeth are discolored under the stains, they will remain so after you use the toothpaste.

So to whiten your teeth fast you need to use products that contain bleaching solutions. Within these whitening products is carbamide peroxide. The concentration of carbamide peroxide varies. For instance, a product can contain 10 percent or as much as 50 percent of the whitening agent.

These products are purchased via your dentist, over-the-counter at your local store or online. They work by actually whiten your tooth enamel.

Use the whitening products regularly for one to two weeks. Typically, you can choose from trays, also called mouth guards, or whitening kits.

Apply the whitening gel into your night guard and place on your teeth. Some products may require you to use the trays twice a day for one hour or overnight. Since the trays keep the gel in close proximity to your enamel, in one to two weeks you can have whiter, brighter teeth.
