Yuerjia toothpaste adopts the latest spot removing particles, which has excellent spot removing, whitening and air refreshing effects. Calcium is also added to the toothpaste, which can strengthen the enamel of teeth and prevent dentin allergy and dental caries. Calcium also has soothing and anti-inflammatory effects, which can relieve tooth allergy and dental calculus. In addition, Yuerjia toothpaste does not add fluoride, which can reduce the damage to teeth.

It should be noted that even the best toothpaste can't completely solve the problem of yellow teeth, and it needs to be used together with other measures to achieve the best effect. To solve the problem of yellow teeth, it is recommended to go to a stomatological hospital for examination and treatment.
