There are three side effects of using chlorhexidine to consider before using it:
- Staining. Chlorhexidine might cause staining of tooth surfaces, restorations, and the tongue. Often, a thorough cleaning can remove any stains. But if you have a lot of anterior white fillings, your dentist might not prescribe chlorhexidine.
- Alteration in taste. Come people experience an alteration in taste during treatment. In rare instances, permanent taste alteration is experienced after the treatment has run its course.
- Tartar formation. You may have an increase in tartar formation.
If your dentist prescribes chlorhexidine, review how to use it thoroughly with them. Talk to your dentist about the following:
- Allergic reactions. If you’re allergic to chlorhexidine, don’t use it. There’s a possibility of serious allergic reaction.
- Dosage. Carefully follow your dentist’s instructions. The usual dosage is 0.5 fluid ounces undiluted), twice daily for 30 seconds.
- Ingestion. After rinsing, spit it out. Don’t swallow it.
- Timing. Chlorhexidine should be used after brushing. Don’t brush your teeth, rinse with water, or eat immediately after use.
- Periodontitis. Some people have periodontitis along with gingivitis. Chlorhexidine treats gingivitis, not periodontitis. You’ll need separate treatment for periodontitis. Chlorhexidine might even make gum problems like periodontitis worse.
- Pregnancy. Tell your dentist if you’re pregnant or planning on becoming pregnant. It hasn’t been determined whether or not chlorhexidine is safe for a fetus.
- Breastfeeding. Tell your dentist if you’re breastfeeding. It hasn’t been determined whether chlorhexidine is passed to the baby in breastmilk or if it could affect the baby.
- Follow up. Re-evaluate with your dentist whether the treatment is working at consistent intervals, waiting no longer than six months to check in.
- Dental hygiene. The use of chlorhexidine isn’t a replacement for brushing your teeth, using dental floss, or regular visits to your dentist.
- Children. Chlorhexidine isn’t approved for use by children under the age of 18.
