How long do chlorhexidine stains last?

Chlorhexidine stains typically last for a few days, depending on the intensity of the stain. Stains on porous surfaces such as stone or grout tend to last longer than stains on nonporous surfaces such as glass or metal. To prevent staining, you should rinse the surface with water after applying chlorhexidine. If you have already stained the surface, you can use a cleaning solution with bleach to remove the stain.

Chlorhexidine, a commonly used antiseptic, can in some cases cause slight discoloration of the teeth. This staining can be temporary and can be removed with professional cleaning. If you are concerned about discoloration from chlorhexidine, it is best to consult a dental professional for advice.
