Chlorhexidine - What is the best method to whiten my discolored teeth from using this product? My?

The best method to whiten your teeth is by use of custom trays with a professional whitening agent. This method is approved by the ADA. Some baking soda can be too abrasive and wear away at your teeth.

This is good advice. Baking soda whitens teeth. Baking soda is able to penetrate the teeth’s enamel and lighten the stains from a yellow or brown to give a much whiter appearance. This is good preventative treatment if using chlorhexidine mouthwash.

If this does not remove the discolouration adequately then professional cleaning by a dentist or dental hygenist will help remove the stain.
