What is a natural teeth whitener?

A natural teeth whitener refers to methods and items that do not contain synthetic whitening materials, such as bleaching ingredients. Some natural teeth whiteners include crunchy vegetables and fruits, such as celery and raw apples, that provide an abrasive surface that scrapes stains from the tooth enamel.

Teeth stains can also be removed by brushing them using a mixture of baking soda and lemon juice paste. The mixture should typically be applied on the teeth and left to sit for one minute before being brushed off. Baking soda helps remove surface stains from the teeth, while lemon juice contains citric acid, which can create a bleaching effect.
