A few years ago if you wanted to achieve a beautiful bright and white set of teeth, you had to take out of your pocket quite a hefty fee at the dentist’s. The situation has changed by now, because there are plenty of different types of teeth whitening kits available, which are quite affordable, and you can apply the treatment at home.

Certainly there are high quality kits that give exceptional results, but there are also several teeth whitening devices that only advertise they are good, but they ultimately fail to offer any results at all. Therefore, you need to be careful when purchasing such teeth whitening kits, and make sure you invest into a device that is of high quality and which is recommended by health specialists.

Teeth Whitening Toothpastes

Firstly, there are the so called “brush-on” teeth whitening systems. In this category, you will find the different toothpastes that contain whitening agents, so you will basically get cleaner and whiter teeth with every brushing.

However, the whitening toothpastes are not to be used as a main whitening solution, especially if your teeth are extremely stained. This whitening method s relatively cheap and it will help you get teeth that are one shade whiter than your natural set of teeth.


Teeth Whitening Strips

Then, there are the teeth whitening strips available, which have a whitening gel coating and which must be worn for quite an extended time until you see the desired results. Most often, the gel that can be found on these strips is similar to that used in the whitening tray devices. One downside of using these strips is that if you are not careful, and the strips move, you will get an uneven whitening result.

Teeth Whitening Trays

The teeth whitening trays are extremely popular because they are quite affordable and they are also effective. The trays usually contain a special teeth whitening gel, and the trays must be worn for at least half an hour every day.

According to statistics, people who use this method can obtain teeth that are up to 10 or 11 shades whiter than their natural set of teeth. You must make sure that the trays that you use are a perfect fit for your mouth, so that you will get the best results.
