Does Baking Soda Whiten Teeth?

baking soda on teeth whitening

Baking soda or sodium bicarbonate is a salty element that is easily available in most homes. Often baking soda is used to whiten teeth. Teeth whitening can easily be done by bleaching your teeth with peroxides taking the help of an abrasive to remove stains. Baking soda acts as an abrasive that helps lighten and remove stains when applied to your teeth. Baking soda as whitening agent is safe and effective. Please keep in mind that baking soda does not remove deeper stains on your teeth. It can remove coffee and smoking stains, but it will take 5-6 weeks to see results.

Let’s take a look at some advantages and disadvantages of baking soda to whiten teeth.


  • Reduces plaque and gingivitis – Bacteria and plaque buildup in our mouth can cause cavities and gingivitis. Baking soda helps reduce the bacteria count and prevent our teeth from plaque and gum damage.
  • Reduces bacteria – Baking soda helps you get rid of harmful bacteria in your mouth. Rinse your mouth with water and baking soda to maintain a higher pH level in your mouth. A less acidic pH level will reduce the cavity-causing bacteria in your mouth.
  • Fluoride-free – Too much fluoride can cause pain, vomiting, diarrhea, kidney and heart problems. Therefore, choose a toothpaste that has natural ingredients like baking soda, that’s free of fluoride to keep your teeth healthy.
  • Affordable – Baking soda is an inexpensive ingredient that is readily available in every grocery store or drugstore.


  • Unappealing taste and texture – Many people don’t like the harsh taste and texture of baking soda in their mouth. The texture feels like eating sand, and the taste is quite brittle. If you cannot use baking soda straight on your teeth, look for a toothpaste that has baking soda in it. You can also add 2 drops of peppermint oil to improve the taste of straight baking soda in your mouth.
  • Less dramatic whitening – Baking soda is safe for your enamel but shows very light teeth whitening results because it does not remove tough stains.
  • Lack of fluoride – Right amount of fluoride prevents dental cavities. Hence, using baking soda in your toothpaste and avoiding fluoride will not protect you from cavity buildup.
