Like the skin, each person has a different dental hue, which can vary between white, gray, yellow or even blackish. The origin of this coloration is in the genetics itself, but the shade of the denture can also be altered very frequently by the history of taking antibiotics such as tetracycline in pregnancy (widely used in the 1960s in Spain) or for consuming coffee, tea, red wine or tobacco repeatedly, which are the cause of the progressive acceleration of the natural process of darkening of the teeth.
Whitening dentifrices have been proliferating in recent years in the market. These pastes have different compounds (xylitol, silica, bicarbonate…), which have a certain abrasive or irritating component for tooth enamel.
In any case, these dentifrices are only effective against stains adhered to the enamel surface and the most superficial part of the dentin. Against other types of dirt, which affects the inner layers of the dentin and pulp, these pastes have no efficacy, so you should resort to other types of treatments only applicable by specialists.
Whitening dentifrices brighten teeth because they remove, more effectively than classic dentifrices, deposits and stains found on the surface of the teeth, thanks to abrasive agents such as calcium carbonate, dicalcium phosphate, aluminum oxide or Hydrated silica It is convenient that you make your annual visit to the dentist to check the condition of your teeth and perform a dental cleaning that removes tartar and impurities that are deposited on the teeth. The professional will assess the continuity of the use of this type of dentifrices and can offer you, without a doubt, an option for more effective bleaching.
