Can toothpaste and baking soda whiten teeth

Baking soda is sodium bicarbonate, a mild abrasive and alkaline powder. It can help loosen external stains on enamel, while toothpaste supplies cleaning agents and, in many products, fluoride.

Neither ingredient changes the natural colour of the inner dentine in a predictable way, and stains from decay, trauma, medicines, or intrinsic discoloration need a different assessment.

Use a fluoride toothpaste with a soft brush and light pressure twice daily. If you want a lighter shade, a dentist can examine enamel, fillings, crowns, and gum health before recommending a peroxide-based product or another option.

Do not scrub with dry powder, hold the mixture against the gums, or use it on painful, eroded, cracked, or highly sensitive teeth.

Arrange a dental examination if colour change is new, affects one tooth, follows an injury, or occurs with pain, a cavity, gum bleeding, or a rough surface.

Seek prompt care for swelling, fever, facial pain, or a tooth that has darkened after trauma, because whitening does not treat infection or structural damage.

Is the discoloration on the enamel surface or within the tooth?

Would a fluoride whitening toothpaste, custom tray, or another treatment suit my enamel and existing restorations?
