Brushing your teeth with baking soda. A good choice or not so inspired?

In the quest for a brighter smile, many people turn to natural teeth-whitening methods — and baking soda is often seen as an affordable and effective option.

Long before modern toothpaste existed, people relied on natural ingredients to clean their teeth.

Baking soda, as we know it today, began to be used for personal hygiene in the 19th and 20th centuries, when its cleaning and acid-neutralizing properties were discovered. Since then, it has been viewed as a cheap and efficient cleaning agent.

What does baking soda actually do for your teeth?

Baking soda has a slightly abrasive texture, which helps remove surface stains caused by coffee, tea, or nicotine. It also has an alkaline pH that neutralizes acids in the mouth — acids that can lead to cavities. Additionally, it has mild antibacterial properties, helping reduce bacteria in the oral cavity.

Online and in DIY “home remedy” recipes, baking soda has become somewhat of a star ingredient — praised for its whitening effect, freshness, and simplicity.

But how safe is this practice for your oral health? What do dentists say?

Dentists have a balanced view: yes, baking soda can be useful, but only when used in moderation.

Why?

  • Its abrasiveness can wear down tooth enamel, leading to sensitivity;
  • It doesn’t contain fluoride, a key ingredient in modern toothpaste that protects against cavities;
  • It’s not effective at cleaning between teeth;
  • It lacks the antibacterial properties found in professional toothpaste formulations.

Why do people still use it?

Because the idea of “natural” care is increasingly appealing — especially in health and wellness — and many people like the thought of whitening their teeth without chemicals.

It’s also extremely affordable — one small packet lasts a long time. However, while natural methods can seem attractive, it’s essential to stay informed and consult a dentist before adopting them.

Recommended frequency

Experts recommend using baking soda for tooth brushing no more than once or twice a week. It’s important not to replace your regular toothpaste with baking soda, but rather to use it as an occasional supplement in your oral care routine.

Conclusion

Baking soda can be a helpful ally for maintaining a bright smile — but only when used carefully and moderately. For safe, optimal results, consult your dentist before adding it to your oral hygiene routine.

If used daily, you risk doing more harm than good.
