What side effects can chlorhexidine cause during gum disease treatment?
Short answer
Chlorhexidine rinse can cause staining of teeth or the tongue, changes in taste, mouth irritation, and more tartar buildup. Serious allergic reactions are rare but possible. Stop using it and seek emergency help for trouble breathing or swelling of the lips, tongue, or throat. Tell your dentist about other reactions.
Chlorhexidine can leave brown stains on teeth, dental work, or the tongue. It can also change how food and drinks taste. Some people notice mouth soreness, burning, or peeling of the mouth lining. Tartar buildup may increase during use, making professional cleaning especially important.
Ask your dentist about staining before starting treatment, especially if you have visible fillings, crowns, or other dental work. A dental professional may be able to remove some stains. Results vary. Do not try to scrape them off or use harsh whitening products on irritated gums.
Contact your dentist if side effects are bothersome, last, or make it hard to eat or drink. The dentist may need to check your mouth or change your treatment plan. Do not replace the prescribed rinse with another product without asking.
A serious allergy needs emergency care. Stop the rinse and call 911 for trouble breathing, throat tightness, fainting, or swelling of the face, lips, or tongue. Make sure future dental and medical providers know about any suspected chlorhexidine allergy.
