There are lots of products on the market addressing dental hygiene. How to choose a toothpaste brand among so many available options?
What is the composition of regular toothpaste and what are these substances for? A significant amount of abrasives is contained by most toothpaste brands. Their role is to mechanically remove stains and plaque, thus preventing the formation of tarter. Usually, toothpaste contains fluorides that prevent tooth decay.
More often than not, toothpaste contains Sodium lauryl sulfate, a substance to be found in shampoos, proved to be useful in cleaning. Antibacterial agents, such as zinc chloride, help preventing gingivitis, reduce tartar and halitosis. Some toothpaste brands also contain substances used for remineralization. Potassium nitrate, more rarely used in the composition of toothpastes, helps reducing dental hypersensitivity. Some of them contain baking soda and hydrogen peroxide.
Most brands on the market contain colorings, artificial flavors and sweeteners. In order to avoid these substances, some people prefer using organic, herbal toothpastes, where the aroma is given by essential oils, eucalyptus, etc.
Fluorides should be avoided or carefully used with small children, as swallowing larger quantities can be toxic. There are fluoride free toothpaste brands for children available on the market. However, you shouldn’t swallow any kind of toothpaste!
Certain studies suggest that zinc chloride could be dangerous when combined with tap water that has been previously treated with chlorine.
Another controversial issue refers to cinnamon toothpaste, as it is believed by some to have a negative effect on gums.
Also, Sodium lauryl sulfate is an important suspect for mouth ulcers, also holding responsibility for taste alteration after brushing.
Whitening toothpaste usually contains peroxide, but its effect is based on abrasives: it should be carefully used as it might damage the enamel when in excess.
