Brushing your teeth with baking soda can have a certain whitening effect, but it can't achieve the ideal whitening effect quickly. Baking soda is an alkaline substance, which can neutralize the acidic environment in the mouth and remove some stains and pigments on the tooth surface, thus making the teeth look whiter. However, it should be noted that baking soda brushing cannot replace regular tooth whitening products and professional treatment methods.

Using baking soda to whiten teeth requires mixing a proper amount of baking soda with water to make a paste. Then dip the wet toothbrush in a proper amount of baking soda paste and gently brush the tooth surface for about 2-3 minutes. Rinse your mouth with water after brushing your teeth, and then brush your teeth with ordinary toothpaste to remove the residual baking soda.

Although baking soda can remove some stains and pigments, the specific effect varies from person to person, and the whitening effect is relatively weak. If more obvious whitening effect is needed, it is recommended to choose professional tooth whitening products or consult a professional dentist. These products or methods can remove the pigment from teeth more effectively, and can carry out targeted treatment according to individual conditions to achieve better whitening effect.

Maintaining good oral hygiene habits is also the key to keeping teeth white. Brush your teeth twice a day, use fluoride toothpaste, floss or brush your teeth regularly, and avoid smoking, drinking strong tea, coffee and other foods and drinks that will make your teeth yellow, which will help keep your teeth white.

Although baking soda brushing can have a certain whitening effect, it can not achieve the ideal whitening effect quickly. If you want more obvious whitening effect, it is recommended to choose professional whitening products or consult a professional dentist, and develop good oral hygiene habits. Remember, while pursuing whitening, it is equally important to protect oral health!
