Toothpaste; November 4th

Did you know that the Canadian market has more than 200 kinds of toothpaste? No wonder it's hard to only pick ONE!

Here is some information to help you better understand the world of toothpaste and help you make a choice according to your needs.

To prevent tooth decay

Most toothpaste contains sodium fluoride and monofluorophosphate sodium, which are the main therapeutic agents recognized in the prevention of cavities. Some research shows that these ingredients can reduce up to 30% the incidence of bacteria on tooth decay.

Toothpaste for sensitive teeth

There is a tooth sensitivity when the tooth roots and the tubules are exposed.*

* Very thin channels that extend from the dentine to the nerve of the tooth.

Toothpaste for sensitive teeth act by blocking the tubules in the dentin and by numbing sensitive teeth. The main ingredients of toothpaste for sensitive teeth are potassium nitrate and strontium chloride..

Warning : Some toothpaste include the word "whitening". However, whitening toothpastes are more abrasive, which could increase dentine hypersensitivity. 

Antibacterial toothpaste

Bacteria in dental plaque are the main cause of most common dental disease. They are responsible for decay and periodontal disease. The antibacterial toothpaste act as antiseptic and fight against the impact of bacteria. Stannous fluoride and triclosan are the main active ingredients found in antibacterial toothpaste.

N.B. Some studies have shown that triclosan is harmful to health (hormone-disrupting).

Anti-tartar toothpaste

It is important to know that the anti-tartar toothpaste can not remove tartar already formed. The active ingredients pyrophosphates, zinc and triclosan control the formation of tartar, by eliminating calcium and magnesium in saliva. (These are the main minerals responsible for the mineralization of plaque, thus the formation of tartar).


There are certainly a multitude of choices of toothpaste, but they have their specificity and effectiveness. You can count on your dental professional to advise you on the options available to you and your needs. Remember, toothpaste cannot be effective without the daily oral hygiene such as brushing, use of dental floss or others.
