Sodium Bicarbonate or commonly known as baking soda is a household product that is used in cleaning or baking, and it helps to eliminate odours. People usually use it as an alternative to brushing teeth instead of toothpaste. Actually, most toothpaste firms are using sodium bicarbonate as an ingredient component in manufacturing toothpaste. 


When you brush with baking sodas, it helps in teeth whitening. A bright pearly white is formed when the plaque around the enamel is erased. Most plaques are due to the foods or drinks we consume, such as tea, coffee or tobacco- thus the teeth discolour. 


People use baking soda for teeth whitening because when it comes in touch with water, it forms an alkaline solution which releases free radicals that help in teeth whitening. 


Apart from teeth whitening, sodium bicarbonate helps to prevent tooth decay, cavity formation and gum diseases. Do you have bad breath? Baking soda will fight it by balancing acidic levels of residual foods. Is your mouth affected with ulcers? To ingest your meal in peace, use baking soda to neutralize the acidity of the ulcers when combined with water.
Discussing the benefits above seems like using baking soda is useful in tooth brushing, especially when it helps to whiten your teeth

Although there are a few downsides to using baking soda on teeth, stated below.

Damages Enamel

When a person brushes teeth with baking soda on a daily basis, they are prone to damage their enamel. A tooth is a living thing thus damaging the coating leads to tooth decay.

Damages Gums

Due to its abrasive properties, it causes severe damage to the gum which can result in bleeding. It is the same properties that cause the damage in enamel. Thus it should be used less to prevent erosion of the dental formula.

Less Effective in Fighting Cavities

Baking soda does not have the capability to kill the bacteria that causes cavities. The fluoride is very little, it is not sufficient enough to fight cavities. Baking soda on its own does not remove plaque effectively. The bacteria that causes plaque formation is not eliminated by sodium bicarbonate alone.

Unpleasant Aftertaste and It Is Gritty

When a person uses baking soda to brush, it leaves a bad taste in the mouth and an uncomfortable gritty feeling. 
To prevent leaving the uncomfortable aftertaste it is advisable to use it with a pint of toothpaste or a flavour such as a peppermint or strawberry.

Not Well Packaged for Oral Use

Unlike the excellent packaging of toothpaste tubes, baking soda is in messy packages. One cannot tell if any contamination has occurred. Thus it is not advisable for oral use even if it is a cheap option of brushing.

Bad for Dental Glue

People using braces should not use baking soda to brush under any circumstances. Baking soda softens the glue that is used to hold the braces together. It also leaves dark spots on the teeth braces when used regularly.
