Sensitive teeth: what causes?

Before you embark on the quest for the ideal toothpaste for your sensitive teeth, it is best to know the cause of this sensitivity. The weakening of tooth enamel and gingival recession, the main factors of dental sensitivity, can be related to the consumption of certain foods that are too hot, cold, sweet or acid, but also to bad tooth brushing, tooth broken or gingivitis. After consulting a specialist, you will know the origin of your dental sensitivity. Your dentist will then be able to refer you to the toothpaste that will relieve your sensitive teeth and will indicate the best practices of the brushing of the teeth.

Toothpaste for sensitive teeth medicines or cosmetics?

A toothpaste can have two statuses. It can be considered a cosmetic product, which you can buy at the supermarket, pharmacy or parapharmacy. A toothpaste can also be considered a drug, available only in pharmacy. Both types of toothpaste are distinguished by the fact that the medicated toothpaste has obtained marketing authorization (MA) after clinical studies have demonstrated its effectiveness. However, this does not mean that cosmetic toothpastes are not effective. Keep in mind, however, that allegations such as "For Sensitive Teeth" or "Strengthens the Gums" are merely marketing arguments, as these toothpastes have not proved their efficacy before they are put on the market. The UFSBD (French Union for Oral Health) logo is also not a guarantee of effectiveness. It simply means that the fluoride content and abrasiveness of the toothpaste meet the standards.

Tip for choosing toothpaste for sensitive teeth?

If you are very sensitive to hot / cold, then, go to a toothpaste containing strontium chloride, fluorinol or permethol. Indeed, dental sensitivity generally results from a degradation of the tooth collar, that is to say the space between the tooth and the gum. If the tooth is well protected by enamel, the gingival recession will result in bare the base of the tooth. This is composed of micro-holes which make it porous and therefore painful. Thus, toothpaste will fill these micro-holes and form an impermeable layer on the surface of your dentin.
