Baking Soda for Plaque Removal

Benefits of Brushing with Baking Soda

Bacteria forms on teeth after eating and can lead to the buildup of plaque. Plaque can be broken down and removed from teeth by brushing your teeth regularly. Baking soda, or sodium bicarbonate, is a mildly abrasive substance that can be effective at removing plaque from your teeth.

Baking soda is effective in removing the plaque biofilm from the teeth, research shows. It is also inexpensive, easy to find, and therefore easily accessible as a tool for plaque removal to help prevent tooth decay.

Demineralization Properties of Baking Soda on Your Teeth

Carbohydrates in foods can change the pH level in your mouth, creating an acidic environment that can lead to demineralization of your teeth. In turn, this can cause the enamel to erode. The more minerals your teeth lose, the more likely you are to get a cavity, which is when the enamel in the teeth is irreversibly damaged.

Baking soda can help to balance and reverse the acidic pH level in your mouth and therefore aid in preventing this demineralization process.

Baking soda has basic properties that can counteract the acids that contribute to the loss of minerals on your teeth created by foods you eat.

Oral products containing hydrogen peroxide whitens your teeth by oxidizing stains on the surface of your teeth.

Teeth Whitening & Baking Soda

Many foods and drinks, such as coffee and wine, can stain your teeth. There are numerous methods and products on the market for whitening your teeth for cosmetic purposes. Many of these products contain baking soda, as it has been shown to aid in stain removal and teeth whitening.

There are more effective methods of whitening your teeth than using baking soda, studies show. These include dental office treatments and specialized products and toothpastes.

Safety of Baking Soda & Your Teeth

For the most part, baking soda is considered safe and low abrasive, which means that it is safe to use on your teeth. That being said, it is still an abrasive substance, and it can lead to enamel erosion with time.

Baking soda needs to be used with caution and not every day. There are a lot of products on the market today, many of which contain baking soda, that can be better options for daily and regular use.
