Charcoal toothpaste, also called black toothpaste has been a popular trend, marketed as a healthy way of keeping teeth clean and white.
The toothpaste is made from activated charcoal, which is made by heating charcoal with gas. The heating process opens up the pores of charcoal, which allows it to trap chemicals.
Proponents of charcoal toothpaste claim that it acts as a magnet, pulling tarter, bacteria and stains from teeth. In addition to charcoal, these toothpastes contain ingredients that stabilize, flavour and sweeten the toothpaste.
Is charcoal toothpaste safe?
Research on charcoal toothpaste is inconclusive and limited. Hence more studies are needed to determine the safety of charcoal toothpaste.
However some safety concerns do exist. Charcoal may accumulate in the cracks and gaps between the teeth and stain the teeth or a dental restoration.
In addition, excessive brushing to remove black charcoal from your teeth may lead to teeth abrasion. These toothpastes may not contain fluoride, which is essential in preventing tooth decay.
Hence, solely relying on charcoal toothpaste could increase the likelihood of cavities.
Whitening vs. Charcoal toothpastes
Whitening toothpastes use abrasives and bleaching agents intended to whiten the teeth. On the other hand, charcoal toothpastes rely on properties of the activated charcoal to remove the stains.
Benefits
Proponents of charcoal toothpaste claim that it has cosmetic and health benefits. However, there is no sufficient evidence to support these claims.
One of the primary reasons people use charcoal toothpastes is because they believe it’s a natural way to whiten their teeth. However, studies do not support this claim. A study comparing the whitening effects of charcoal toothpaste and regular fluoride toothpaste showed no significant difference.
Some claim that charcoal toothpastes have antimicrobial properties, but the evidence for this assertion is weak.
Charcoal toothpastes can be abrasive and harmful to the teeth when used for a longer time.
Risks
Charcoal toothpastes can be abrasive, they lack fluoride. They may damage the enamel and lead to increase in the number of cavities.
Lactating women, pregnant women and women on birth control pills should avoid using charcoal toothpastes.
While charocoal toothpastes shouldn’t be swallowed, it may happen accidentally. In addition, charcoal toothpastes may get absorbed through the mucous membrane in your mouth. Ingested activated charcoal may reduce the absorption of drugs and other chemicals. Hence, you should be cautious about using charcoal when you are on medications.
Charcoal is messy, so be prepared to clean up afterwards.
