  1. Use of plain baking soda powder
  • Add a few drops of water into half a tsp. of baking soda in a cup and mix well to create a paste. You may now use your fingers to apply the paste on the stain marks, let it remain on the teeth for 2 to 3 minutes, and then wash it off. If the stain marks are very adamant, then you may scratch them away with fingernails when the baking soda is still there on the teeth.
  • Alternatively, you may apply the paste on a toothbrush so that all the bristles are covered with it and then brush the teeth for around two minutes. This will not only remove the stains but will also provide an overall whitening effect. Brush thoroughly in an up and down motion and not sideways. Avoid brushing the gums as it can result in bleeding and burning sensations.
  • Baking soda does not have a very pleasant taste. Also, it is very abrasive and can erode and damage the tooth enamel. Hence, do not brush for more than 2 minutes. Also, orthodontic glue dissolves in baking soda. Hence, people with a permanent retainer or braces should not use baking soda to whiten the teeth.
  • After brushing rinse the mouth several times with lots of water and then use a mouthwash. Also make sure that the toothbrush is completely rinsed and clean.
  • For really bad stains, you may brush with baking soda every second day for 2 weeks. Minor difference in teeth whiteness is noticed in a few days; but after a couple of weeks the difference is significant and very visible.
  • If issue persists even after using baking soda to brush the teeth for 2 weeks, then continue brushing, but only once or 2 times a week instead of every other day. This is because frequent use of baking soda can result in increased tooth enamel damage.
  • Make sure that you brush with regular toothpaste on a daily basis even when you use baking soda to whiten the teeth. Baking soda is not a substitute for regular brushing with normal toothpaste. Follow the usually brushing practices with toothpaste, wherein every teeth and every corner of the oral cavity including the tongue are brushed and cleaned. This will prevent gum problems, plaque buildup, bad breath, and cavities, etc.
