Myths and Facts about Teeth Whitening


There is a lot of misinformation on the web about teeth whitening. You can save a considerable amount of time, money, and efforts by avoiding misconceptions. If a brilliant smile is what you are after, then you need to know these myths and facts about teeth whitening. 

Myth – Baking soda and hydrogen peroxide are great whitening tools

Baking soda simply doesn’t work on teeth enamel. Your teeth are like sponge with pores in the enamel that effectively absorb all stains. You need something better than baking soda. Hydrogen peroxide is a great whitening agent. However, when used by amateurs the chemical may come in contact with your skin and tissues, which causes free radical reactions. This is the same reaction behind tissue ageing. 

Myth – Whitening gum and toothpaste helps

Whitening chewing gums and toothpastes contain small quantities of whitening chemicals. However, these are present in low quantities or weak amounts to have any actual effect. To see a color change, any whitening product, needs to be on the surface of your teeth for at least 20 minutes. 

Myth – At-home whitening and professional whitening gels are same

Hydrogen peroxide or carbamide peroxide is the functional or active ingredient in all teeth whitening gels. The quantity of this chemical in professional whitening gel is more as compared to at-home whitening gel.

Myth – Stronger the whitening gel, better it is

It goes without saying that stronger whitening gels would speed up the process and give you whiter teeth in a fairly short span of time. This is one of the reasons why many people prefer professional teeth whitening as opposed to at-home whitening. However, stronger is not always better since it may not last as long. Strong chemicals may also cause pain and sensitivity, especially if the procedure is not performed by a dentist. 
The bottom line in this myth is that you can achieve similar results with a lower concentrated teeth whitening gel. This is also a safer way to get your teeth whitened. The best part is that products with lower concentrations of hydrogen peroxide would ensure that your teeth stay whiter for longer. 

Myth – Teeth stay whitened forever after the procedure 

The color of your teeth would have changed for a variety of reasons and habits, such as smoking, drinking coffee, and poor oral hygiene among others. Your teeth would discolor quicker if you do not change your habits. While the color change after a teeth whitening procedure tends to stay permanently, the process of aging is not slowed or reversed. You would require regular touch-ups to maintain the desired results. 

Myth – Lemons and strawberries help in whitening teeth

This is true. However, the results come at a cost. Lemons and strawberries contain acids that can eat away the enamel layer of your teeth. This may result in permanent damage.
