- Brush with a fluoride-containing toothpaste afterward as baking soda cannot prevent caries. Due to its mild abrasiveness, it might cause erosion of enamel surface if used regularly. Use this paste every alternate day to avoid causing harm to teeth.
- You can mix baking soda with your toothpaste itself if possible. You will notice results within a few days, but noticeable whiteness will be visible in a couple of weeks (2).

Whitening is not permanent- done at home or the dental chair. Period! You will have to let go of your habits like smoking or excessive consumption of tea/coffee if you want to avoid “return of the stains.”
Try using a straw while consuming stain-causing liquids. Straw will ensure that your teeth don’t come in contact with the liquid. If you don’t let go of your smoking habits, then the whole procedure will fall flat on its face.
Benefits of baking soda for teeth whitening
Baking soda not only whitens teeth but also has other positive effects on the oral cavity. Baking soda helps in maintaining the alkaline pH of the oral cavity (3) and the process is cheap.
Also, baking soda helps fight bad odor by eliminating the odor instead of masking the bad odor temporarily like in the case of mouth fresheners.
Disadvantages of baking soda for teeth whitening
- The main drawback is the abrasiveness of the baking soda powder. If it is used in excess, then it may weaken the enamel and causes several dental issues such as erosion of enamel, tooth sensitivity, brittle teeth, cavity or caries.
- Baking soda doesn’t have the property to prevent caries, so it cannot be used alone. Every time after you use baking soda, teeth should be brushed using toothpaste and rinse thoroughly. If you wear braces or retainers then avoid using baking soda since it might react and leave dark spots on the tooth surface.
- People with receding gums should avoid using baking soda since the tooth surface protected by gums is exposed in this case. This region is weaker and more sensitive than the enamel. Using baking soda will only worsen the tooth by hastening the erosion process.
- Erosion of tooth surface is an irreversible process. Hence, it is important not to overuse baking soda in teeth whitening.
