There are many teeth whitening measures to be availed these days but not all of these measures or procedures are effective. However, you can always try them out.

You can whiten your teeth with the use of whitening gels available in the market or you can go to the dentist and opt for professional procedures. While the at-home measures and procedures are inexpensive and safer, the others involve too much expenditure and might not give you the kind of results that you are looking for.

Toothpastes are being used for ages now for cleaning out teeth once or twice daily. But all these toothpastes aren't really effective in giving us the right kind of treatment for our teeth. Whitening toothpastes are available in the market as well and these contain chemicals which might be harmful for the teeth. Nonetheless, whitening gels are a better option and have been tired and tested for long. The results are good enough to be spoken about. But before trying one, you, must know what whitening gels are?

Whitening gels are usually clear gels and contain hydrogen peroxide that needs to be applied with the use of a brush to the teeth surface directly. The gels are to be applied twice daily for 2 weeks. The initial difference can be noted within a few days, but for the final results you'll have to wait for 4 months.

Bleaching is also a very common procedure in whitening teeth. Bleaching or teeth whitening includes the use of oxidizing agents like caramide peroxide and hydrogen peroxide to lessen the stain. These oxidizing agents penetrate through the porosities in the enamel, which is crystal structure resembling a rod and then oxidizes the interprismatic deposits of stain. Over a certain time period, the layer below the enamel, the dentin, also gets bleached. The bleaching effects are likely to last longer than any other procedure, but you need to maintain certain restrictions in order to prevent stains.

Before you take up a teeth whitening procedure you need to know certain things:

Use fitted trays. These trays can be obtained from the local dentist. This is a must. The bleach must directly reach your teeth and therefore a tray that fits your teeth well is essential.

For the best teeth whitening gel or bleach you can consult the local dentist. They would give you the best suggestion based on the condition of your teeth and your basic requirement.

Avoid using the bleach or whitening gels for too long; it can cause damage to the gums. Consult with the dentist before you start using one.

While choosing a teeth whitener or gel for yourself you, just check for the percentage that has been marked on the label. 16 percent is optimal and you should know that. You might also notice bleaches of 10 percent, which is very low. Such gels would take too long to give the desired result. But bleaches that come at 20 percent are very strong and can lead to sensitivity of tooth.

People often prefer to bleach one arch after the other; this can also be an option to note the difference between the two arches. But you can also bleach two arches together.

What actually matters is the right amount of bleach or gel to be applied to the trays and worm for a considerable period of time for better results.
