Carried away by advertisements promising shiny white teeth? Here is why you need to be careful | Life-style News


“Your whitening toothpaste will turn your teeth yellow,” cosmetic dentist Dr. Brona Keane told personal trainer and health speaker Carl Henry on his podcast. Whitening is regulated in the European Union, and for over-the-counter products, Whitening strips, toothpastes, and whitening mouthwashes, for example, must contain no more than 0.1% hydrogen peroxide, so in comparison, when you get professional whitening, the dosage prescribed by your dentist is 6%.


She emphasized how The amount of hydrogen peroxide varies significantly. To compensate for this, she says, most brands add “acids and abrasive particles to whiten teeth.” This results in these products only being effective on the surface layer of the tooth. Abrasive particles can also cause the top white layer, or enamel, to thin, causing teeth to yellow over time.

Can whitening toothpaste cause enamel erosion, causing teeth to turn yellow over time?

Dr. Niyati Arora, BDS, MDS (prosthodontist) of Krown Hub Dental Clinic in Pitampura agrees with Dr. Keane. “The usefulness of whitening toothpaste has been a topic of discussion, and the answer is subject to question and controversy,” she said.


“The whitening effect of current whitening toothpastes mainly benefits from two factors.

  1. Use of mechanical abrasives
  2. ⁠Use peroxide.

Whitening toothpastes are generally safe to use. However, if used for a long time, it can damage the enamel and irritate the gums and teeth,” she told indianexpress.com.

The disadvantage is that mechanical abrasives such as hydrated silica, charcoal, and baking soda can slowly, over time, wear down the tooth surface. She says these abrasions slowly wear away at the outermost layer of our teeth and the stains on them, giving the impression that the teeth are being cleaned. But in the long run, you lose something more important, which is enamel—the outermost layer of our teeth and the protective layer that prevents tooth sensitivity.

Certain oral or dietary habits may interact with whitening toothpaste and cause teeth to turn yellow

“Many of our oral and dietary habits can contribute to yellowing of teeth,” says Dr. Arora. It is generally believed that brushing your teeth vigorously back and forth with a medium or hard toothbrush will result in cleaner teeth. Not only does this cause abrasions and enamel wear, causing teeth to become yellow, It can also cause our gums to recede. She advises, “We should all use soft or extra-soft bristle toothbrushes and use soft hands to move the toothbrush in circular or up-and-down motions to prevent this from happening.”

Dr. Arora points out another common habit that can lead to yellowing of teeth—the use of tooth powder Tooth decay. These are nothing more than abrasive powders that can reduce enamel and cause damage to your gums.

Additionally, some common foods that can cause staining include tea, coffee, wine, and aerated drinks like Coke and Pepsi. “Tea (including green tea) and coffee contain tannins, which can cause staining, but these are only external stains that can be easily removed with professional cleaning and polishing. Aerated drinks are acidic in nature and can wear away enamel, causing our teeth to become stained. Get sensitive and yellow,” Dr Arora told indianexpress.com.

How the frequency of using whitening toothpaste affects the likelihood that it will cause yellowing or discoloration of teeth

“Short-term or dentist-prescribed use of whitening toothpaste may cause little damage or side effects to your teeth,” says Dr. Arora. But, Long-term use of them can cause damage not only to the teeth but also to the gums.

Side effects don't happen overnight, or even within a week or month. Its effects take time to settle and appear. Therefore, the effects of wear caused by abrasive particles will show up within a few months.

As for the use of peroxide, Dr. Arora mentioned that long-term use or abuse of peroxide can damage enamel, irritate gums, and lead to long-term sensitivity. These serious side effects have led to strict regulations on the amount and concentration of peroxide allowed in toothpaste.
