If you've had an extraction, an implant or you have inflamed gums, we've probably recommended a chlorhexidine mouthwash. It's one of the most widely used antiseptics in dentistry, but it needs to be used correctly. Dr. Lorena Rosado, dentist at Somriures Gavà, explains.
What is chlorhexidine?
It's a compound with a broad-spectrum antiseptic effect, able to kill bacteria and fungi. Its big advantage is that it sticks to the tissues of the mouth and keeps working for hours after rinsing. That's why it's used as a complementary treatment when there's a risk of infection or when normal hygiene isn't enough.
It mainly comes as a mouthwash, although gels and sprays also exist.
When is it used?
- Gum disease: gingivitis and periodontitis, to support treatment at the clinic.
- After surgery: extractions, implants or gum grafts, to prevent infection while you can't brush the area properly.
- Mouth ulcers: helps them heal faster.
- Times when hygiene is difficult, for example after surgery or at specific moments during orthodontics.
How to use it correctly
- Rinse with 10–15 ml undiluted for 30 seconds, usually twice a day, unless we give you a different routine.
- Don't swallow it.
- Wait about 30 minutes before eating or drinking.
- Use it separately from brushing: some toothpaste ingredients reduce its effect. Ideally, brush, rinse well with water and wait a while before using the mouthwash.
- Stick to the duration we recommend: usually a few days or weeks.
Precautions and side effects
- Tooth staining: prolonged use can stain teeth and tongue brown. It's removed with a professional cleaning.
- Altered taste: some patients notice food tastes different while using it. It goes away when you stop.
- More tartar: continued use can increase tartar build-up.
- Allergies: uncommon, but if you notice itching, swelling or irritation, stop using it and contact us.
That's why at Somriures Dental we recommend using chlorhexidine only on professional advice and for a limited time. It isn't a mouthwash for everyday use indefinitely.
Does it replace brushing?
No. Chlorhexidine complements hygiene, but it doesn't remove the plaque that builds up on the teeth. Brushing, flossing or interdental brushes and professional cleanings are still essential.
Frequently asked questions
Can I use chlorhexidine every day?
Only for the period we recommend. There are gentler mouthwashes for daily use.
What if I've already got stains?
Don't worry: they're removed with a professional dental cleaning.
Can children use it?
Only if the dentist recommends it and when the child can spit without swallowing.
