Does Baking Soda Whiten Teeth

A dazzling smile is a universal desire, but the journey to achieve it is often hindered by tooth discoloration. The question, “Does baking soda whiten teeth?” has piqued the interest of many seeking a natural remedy for a brighter, whiter smile. In this informative blog, we will delve into the mechanisms behind how baking soda aids in teeth whitening, discuss the proper usage, and address common queries surrounding this at-home dental remedy.

How does Baking Soda Whiten Teeth?

Baking soda, composed of the slightly abrasive chemical compound sodium bicarbonate, acts as a gentle yet effective stain remover on the tooth surface. Its mild abrasiveness facilitates the removal of stains, making teeth appear white and bright. Additionally, the alkaline nature of baking soda neutralises mouth acids, inhibiting bacteria growth that leads to plaque formation—a primary cause of tooth discoloration and damage.

By eliminating plaque and creating an unfavourable environment for bacterial growth, baking soda contributes to cleaner and brighter teeth. It’s important to note that while baking soda is a valuable aid, severe tooth discoloration warrants professional dental treatment.

How to Use Baking Soda For Teeth Whitening:

Maximise the benefits of baking soda for teeth whitening by following these simple steps:

  • In a bowl, mix one tablespoon of baking soda with an equal amount of water to create a thick paste.
  • Coat your toothbrush bristles with the paste.
  • Gently brush your teeth in a circular motion for at least 2 minutes.
  • Spit out the paste and rinse your mouth thoroughly with clean water or mouthwash.

Consistent use, around 2 to 6 weeks, is recommended for noticeable results in removing coffee or smoke stains from the tooth surface.


While utilising baking soda for at-home teeth whitening proves cost-effective, it may not match the efficacy of professional dental treatments. Some individuals find its texture and taste unpleasant, but it serves as an ideal fluoride-free option for those seeking an alternative to traditional toothpaste. Maintaining good oral care practices with baking soda is crucial for visible results. For faster and more effective teeth whitening, consulting a dentist is recommended. Bsmiles, a trusted dental service, offers effective teeth whitening treatments delivered by experienced professionals.
