Chlorhexidine may cause some tooth discoloration or increase in tartar formation. It is important to see your dentist for removal of any stain or tartar at least every six months or more frequently if your dentist advises.

Chlorhexidine may taste bitter to some patients and can affect how foods and beverages taste. This will become less noticeable in most cases with continued use of chlorhexidine.

To avoid changes in taste, rinse with chlorhexidine after meals.

Do not rinse with water or other mouthwashes immediately after rinsing with chlorhexidine.

Patients should avoid dental floss at the site of Chlorhexidine dental chip insertion for 10 days after placement, because flossing might cause the chip to fall out.
