effectiveness

Sensodyne toothpaste works differently depending on the active ingredient in the product - potassium nitrate , strontium acetate / chloride .

Potassium Nitrate : The potassium ion hyperpolarizes the nerve and prevents it from firing. The nerve impulses and thus the sensation of pain are reduced.

Strontium acetate and chloride : These compounds have a similar chemical structure to calcium. Toothpastes based on strontium (acetate and chloride) can therefore replace some of the lost calcium and block the exposed tubules in the dental tissue. This helps prevent the fluid from moving within the tubules in response to a sensory stimulus that might otherwise cause toothache.

Some Sensodyne products contain calcium-sodium-phosphosilicate CSPS (Novamin), which appears to help with tooth sensitivity. A clinical study published in 2015 showed that toothpaste containing 5% CSPS could have the potential to mineralize and seal the dentin around the mouth . Sensodyne has removed the calcium-sodium-phosphosilicate from their US products.

history

Sensodyne is a toothpaste brand , the first of Block Drug, one company was sold based in Brooklyn, New York, which was founded in 1907 by the chemist Alexander Block.

In 1925, the manufacture of dental care products became the company's focus. In 1938, Block developed Polident, a denture cleaning product that is still popular more than 80 years later. Leonard N. Block followed his father into the family business, which moved to New Jersey, New York in 1970 when it was acquired by the British pharmaceutical giant that became GlaxoSmithKline (NYSE: GSK).

The toothpaste was first marketed in 1961 as a desensitizing toothpaste based on a strontium chloride formulation.

In 1980, Sensodyne launched a new toothpaste containing potassium nitrate, a mild local sedative. In 2000, Block Drug was bought by GlaxoSmithKline.

Counterfeit products and product recalls

In 2007, GlaxoSmithKline tracked down counterfeit manufacturers of Sensodyne after a consumer in Panama put diethylene glycol, a toxic component of antifreeze, on the label of their toothpaste.

On July 15, 2015, GlaxoSmithKline Consumer Healthcare announced the recall of certain quantities of Sensodyne Repair & Protect Toothpaste and Sensodyne Complete Toothpaste due to the possible presence of wood fragments in the products. The recall also applied to the company's Biotene toothpaste brand. The recall was a precautionary measure based on a small number of complaints and no injuries were reported. The recall applies to products manufactured between 2013 and September 2014 and shipped between June 2013 and April 2015.
