Need some dental expertise! my teeth are getting yellow . what is the best whitening toothpaste?

Brush, bleach: Any toothpaste will do. Bleaching is a preferred treatment choice over long term use of whitening toothpaste because of potential abrasive wear on the enamel upon using whitening toothpaste. As the enamel wearing down, the tooth become more translucent, greyish with a more yellow dentin color shine through.

Whitening toothpaste: All whitening toothpastes rely on being more abrasive to remove superficial stains from coffee, tea, cigarette smoke etc. They do not contain any whitening ingredients.While they may help initially, continued use can make the teeth darker as the outer lighter color is worn away revealing the darker inner structure. Also may make them more sensitive.

Surface stains: All the good whitening toothpaste out there is to remove surface super facial stains on the teeth, use one that is mild abrasive in nature like synsodyne gentil whitening, for more deeper internal stains get a professional whitening at your dentist..
