The activated carbon according to the online encyclopedia is derived from carbonaceous materials product having an exceptionally high surface area, measured by nitrogen absorption and is characterized by very microporous. These micro pores make it a material with absorption power but it is also a hard abrasive material so, applied to the enamel continuously and with friction, it can wear out badly.
Activated charcoal (or active carbon) tooth whiteners usually promise harmless teeth whitening and attribute this bleaching effect to the absorption power of activated carbon that removes dirt from teeth. What the experts say is that the activated carbon, in getting in contact with the saliva, absorbs what is saliva and little else.
Applied with high frequency, it becomes abrasive for enamel. So what can seem to whiten the teeth what it really does is to wear away the protective layer called enamel leaving the tooth unprotected before external agents and increasing the risk of decay and tooth sensitivity. According to the study Surface changes of enamel after brushing with charcoal toothpaste the size of the particles is such that with friction, the roughness of the surface of the enamel increases increasing the proliferation of bacteria and biofilm and the resistance of the bacteria. More risk of caries and periodontal diseases.
The American Dental Association (ADA) says there is no scientific evidence to ensure that products with activated charcoal help whiten teeth. Activated carbon is an abrasive material that, in fact, can turn them yellowish if, after using them, the enamel is removed and the dentin is visible (an inner layer of the softest and weakest tooth).
Are “natural” bleaches “harmless”?
The ADA also talks about home remedies such as baking soda, acidic foods, oils and spices. According to the Association, bicarbonate has an abrasive effect such as activated carbon. On using lemons or vinegar, it is recommended not to have them in contact with the teeth for a long time because of its corrosive effect and the spices clarifies that there is no scientific evidence to show that the oil or turmeric whiten the teeth.
The General Council of Dentists recommends going to a dental clinic if you want to whiten your teeth and follow the instructions of a licensed dentist. It is important that a dentist reviews the oral health of the patient before a whitening treatment to rule out possible oral health problems and to determine the appropriate whitening treatment for each case. It must be remembered that sometimes internal bleaching is required instead of external bleaching and that can only be diagnosed by a dentist.
The American Dental Association recommends following proper oral hygiene:
- Brush teeth with special attention to the interdental space
- Minimum teeth washing 2 times a day for 2 minutes
- Use toothpastes approved and recommended by dental associations
- No Smoking
- Reduce the consumption of food and drinks that stain your teeth: coffee, tea, wine …
- Visit the dentist at least once a year
We also recommend going to a trusted dentist if you want to perform a teeth whitening, perform tooth whitening in a dental clinic with qualified professionals and appropriate materials, perform proper oral hygiene at home, perform dental hygiene professionals and periodic dental reviews and reduce the consumption of foods that stain the enamel.
