Now let’s consider the different options open to us once we decide to go ahead with teeth whitening.
1) Whiten teeth at a dentist’s office
In this method the result you get is fast and excellent. The procedure is quickly done with, over in just about a couple of hours. Though the result is immediate it’s the most expensive teeth whitening method.
2) Whiten teeth strips
These are sold over the counter in almost all the drug stores these days. These are easy to use, fairly inexpensive and most of them work well also. The result produced always depend upon the strength of hydrogen peroxide used in that particular strip.
3) Teeth whitening trays and gels
Though teeth whitening trays and gels are effective they may take from 4 days to up to a couple of weeks to give the desired result. These trays have to be worn over your teeth for a couple of hours every day or overnight.
4) Teeth whitening toothpastes
Teeth whitening toothpastes are another option. These contain polishing agents, mild abrasives and some special chemicals that removes stains. They do not bleach your teeth.
5) Natural method to whiten teeth

You can also resort to some make-at-home preparations for whitening the teeth. The most popular is a strawberry and soda bicarbonate mix. Blend 1 ripe strawberry with 1/2 a cup of soda, apply on to your teeth, keep for 5 minutes and brush with normal paste and rinse. Do this once a week for good results.
Teeth whitening can be done at home with soda and salt mix or a 3% hydrogen peroxide solution too. Dip your toothbrush in this and brush slowly and gently. Don’t use this methods too frequently as it may damage your tooth enamel.
