3. Are There Any Side Effects?
Chlorhexidine gluconate mouthwash has a few possible side effects, like a change in taste, increased tartar build-up, or staining of the teeth, gums, and dental appliances. But these side-effects typically only appear with long-term use and your dentist or physician will consider those before prescribing.
While severe side effects of using medicated mouthwash are rare, according to the University of Michigan, chlorhexidine gluconate can cause a rare but severe allergic reaction. Call your dentist or physician immediately if you experience any of these symptoms or any reaction after rinsing.
