Do strawberries whiten your teeth?

While looking around for evidence on this teeth whitening technique works, it dawned that there are tons of claims that this method could work but tons in return that they do not work. In reference to the latter, one Bryana Stearns of American University research mentions in her literature review that this method does not work.

She backs her review with a study done by the famous Dr. So Ran Kwon, an associate professor and dental researcher at the University of Iowa who decided to put the strawberry teeth whitening method to the test. According to Dr. So Ran, this remedy does not actually whiten teeth but does something similar to temporarily making it white.

The layer makes the teeth yellowish. In her study, in the Operative Dentistry, she confirmed the authenticity of this method by rubbing a mixture of strawberries that were crushed and in a mixture of baking soda. Normally such trials are done on pulled teeth and this was done on 20 of them for a period of 10 days.

The paste was allowed to seat on the teeth for five minutes. Results showed that it removes plaque and debris from the teeth but does not actually whiten the teeth. More on the opposition, Amy freeman of Colgate, says that while it seems like a simple and tasty way to improve your smile, it doesn’t do much to whiten your teeth.

The silver lining to this is that every research or study done can be challenged and there are a number of facts that can do this. Strawberries can whiten teeth just like using lemon, apple vinegar or oil pulling using swishing coconut oil.

The purported reason for this is that they contain some concentration of acidity and that this can come in handy in removing the stains on the teeth. Nevertheless, note that the reason you get tooth decay is due to the formation of acid by bacteria that metabolize the sucrose in food. This acid left to seat on teeth for long leads to breakdown of the enamel.

It is true that strawberries are acidic and the low pH is due to the presence of a number of acids in the fruit. One particular one is malic acid. This acid is not only found in strawberries, but also in apples. It is an acid ingredient that is found in whitening strips. However, this acid does not actually whiten the teeth but instead removes the stains: says Dr. Kwon.

While the acidity could potentially damages the teeth if used for a long time, there are studies that support the use of malic acid as a whitener of teeth. Such include one done by Sánchez, AR; Rogers RS, 3rd; Sheridan, PJ (October 2004)[1] in which the use of tetracycline and tetracycline derivatives on teeth and the oral cavity has been investigated.

Malic acid has been investigated as a weak teeth whitening agent. In high concentrations however, it could lead to dissolution of the enamel layer. The reason your teeth become yellower is due to exposure of the dentin that bears this color upon erosion of the enamel.

This method has further been studied by an in vitro study similar to Dr. Kwon’s but this time investigating the efficacy of DIY whitening as compared to conventional tooth whitening modalities[2].

More to this limelight, one Peoria dentist, Dr. Bischoff, agrees that indeed this method works and to add, the vitamin C in strawberries acts as a potent teeth whitener.

Especially if you have done a mixture with baking powder (Dr. Kwon; Journal of Odontology). She in fact says that it reduces the surface harness of teeth by close to 10%. This is dangerous.
  2. The use of other bleaching agent such as hydrogen peroxide and carbamide peroxide can lead to erosive effects on the tooth enamel and this has been proven by the America Dental Association and further discussed in a Dental Research in Florida (2012).
  3. Acid demineralization and abrasion of tooth structure and recession are possible side effects of using this method.
  4. The use of acid to whiten teeth and addition of bleaching agents could lead to gingivitis as they may burn the gums and cause inflammation.
  5. Tooth sensitivity could also occur. This is especially dose dependent and high doses therefore could lead to hot and cold sensitivity. According to JADA in a 2002 survey, results showed that there is a 50% chance of mild sensitivity. With moderate sensitivity, there is a 10% while there is a 4% chance of acquiring severe sensitivity.
