Few weeks back, when I shared that there is nothing ayurvedic in popular brands toothpastes, including the one sold by Patanjali, many friends acted reactive. They also shared their personal experiences how so called herbal toothpaste helped them get rid of dental problems.

I responded that, it is mere placebo. There is no health benefit but there are indeed health hazards due to chemicals loaded with paste.

Read this research.



Toothpaste alone does not prevent dental erosion or hypersensitivity

The rising prevalence of dental erosion and dentin hypersensitivity has led to the emergence of more and more toothpastes on the market that claim to treat these problems. While no such toothpaste existed 20 years ago, today, many brands with different attributes are being offered.

“Toothpaste won’t solve the problem completely. Dental erosion is multifactorial. It has to do with brushing, and above all, with diet. Food and drink are increasingly acidic as a result of industrial processing,” said Samira Helena João-Souza, a PhD scholar at the University of São Paulo’s School of Dentistry (FO-USP) in Brazil and first author of the article.

Chemical and physical factors of desensitizing and/or anti-erosive toothpastes associated with lower erosive tooth wear

Toothpastes have a complex formulation and their different chemical and physical factors will influence their effectiveness against erosive tooth wear (ETW). We, therefore, investigated the effect of different desensitizing and/or anti-erosive toothpastes on initial enamel erosion and abrasion, and analysed how the interplay of their chemical and physical factors influences ETW. Human enamel specimens were submitted to 5 erosion-abrasion cycles using 9 different toothpastes and an artificial saliva group, and enamel surface loss (SL) was calculated. Chemical and physical factors (pH; presence of tin; calcium, phosphate and fluoride concentrations; % weight of solid particles; wettability; and particle size) of the toothpaste slurries were then analysed and associated with the amount of SL in a multivariate model. We observed that all desensitizing and/or anti-erosive toothpastes presented different degrees of SL. Besides pH and fluoride, all other chemical and physical factors were associated with SL. The results of this experiment indicate that enamel SL occurs independent of whether the toothpastes have a desensitizing or anti-erosive claim, and that lower SL is associated with the presence of tin, higher concentration of calcium and phosphate, higher % weight of solid particles, smaller particle size, and lower wettability.
