There are types of mouthwash that can stain teeth, listed below are the following:

Cationic Antiseptics

  • Produce yellow-brown staining
  • Examples – Chlorhexidine, Cetylpyridinium Chloride (common ingredient in mouthwashes)

Polyvalent Metal Salts

  • Produce golden yellow staining
  • Examples – Stannous Fluoride

Phenolic Mouthwashes

  • Produce yellow staining
  • Examples – Listerine (particularly the thymol and eucalyptol ingredients)

If you do use one of these mouthwashes and are concerned about increased staining, limit your rinsing to nightime only, right before bed. The staining ingredients react with dietary chromogens (staining compounds in foods and drinks) to increase the precipitation of stains onto the surface of your teeth. By rinsing at night, there is a much lower risk of your mouthwash interacting with what you eat or drink to produce additional staining.
