Sodium Bicarbonate or commonly known as baking soda is a household product that is used in cleaning, baking and 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 food we consume tea, coffee or tobacco thus the teeth discolor. 


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 a bad breath? Baking soda fights bad breath 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 brushing teeth especially when it helps to whiten your teeth. The `cons outdo the pros as stated below.

 

Damages Enamel

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

Damages Gums

Due to its abrasive properties, it causes a 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 bacteria that causes cavities. The fluoride is very little that it is not sufficient enough to fight off 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 After Taste and It Is Gritty

When a person uses to brush with baking soda, 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 flavor such as a peppermint or strawberry.

Not Well Packaged for Oral Use

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