Do whitening toothpastes cause tooth sensitivity?

None

Yes, whitening toothpastes can cause tooth sensitivity. The active ingredient, usually hydrogen peroxide, is linked to increased tooth sensitivity and mild gingival irritation, with the degree of sensitivity related to both the concentration of peroxide and the duration of use[1][3]. Additionally, whitening agents can create small defects and subsurface pores in the teeth, leading to discomfort, especially with hot or cold products[2][1]. While this sensitivity is typically short-term and not permanent, those experiencing continued discomfort should consult a dental professional[3].

What's the story behind Vicks Vapour Rub?

None

Vicks VapoRub was developed in the 1890s by pharmacist Lunsford Richardson in Greensboro, North Carolina, inspired by a need to help his sick son, who suffered from croup. Initially called Richardson's Croup and Pneumonia Cure Salve, it incorporated menthol and other soothing ingredients blended in petroleum jelly. The product was renamed Vicks VapoRub in 1911 in honor of Richardson's brother-in-law, Dr. Joshua Vick, who assisted him in accessing a laboratory for its production[1][2][3].

The salve gained significant popularity during the 1918 flu epidemic, with sales soaring from $900,000 to $2.9 million in just one year[4]. Over the decades, Vicks has remained a trusted name, evolving from its original use to address various ailments, including cough, colds, and even nail fungus[4].
