How does chlorhexidine work?
Chlorhexidine is an antiseptic and disinfectant. It works against a wide range of bacteria by stopping them growing and spreading. It also works against some fungi and viruses, particularly the ones found in your mouth and on your skin.
With the dental treatments, chlorhexidine helps prevent the build-up of plaque by forming a protective coating over your gums and teeth. This helps prevent or treat mouth infections and gum disease. It also helps ease your symptoms if you have a mouth ulcer or sore throat.
When will I feel better?
Chlorhexidine will start to work as an antiseptic straight away. The time it takes to feel other benefits will depend on what you're using chlorhexidine for. Ask your doctor or dentist about what to expect with your treatment.
If your symptoms get worse at any time during your treatment, speak to your doctor, dentist or a pharmacist.
Will it affect my contraception?
Chlorhexidine is unlikely to affect any type of contraception, including the combined pill and emergency contraception.
Can I drive or ride a bike?
Yes, you can drive or cycle while using chlorhexidine.
Can I drink alcohol while using chlorhexidine?
Yes, you can drink alcohol while using chlorhexidine.
Some chlorhexidine treatments, such as the dental spray or sore throat spray, contain alcohol already. Although the amount that passes into your blood is small, the additional alcohol may make you feel sleepy, dizzy or give you a headache.
If this happens, do not drink alcohol while you're using chlorhexidine.
Is there any food or drink I need to avoid?
When using dental chlorhexidine treatments, the lozenges or sore throat spray, wait at least 30 minutes before eating or drinking.
There is no specific food or drink to avoid when using chlorhexidine. However, be aware that some of the dental sprays and mouth sprays contain alcohol.
Can lifestyle changes keep my mouth and teeth healthy?
You can help your oral hygiene by following these tips:
- Brush your teeth for about 2 minutes last thing at night before you go to bed, and on one other occasion every day. It does not matter if you use an electric or manual toothbrush, but some people find it easier to clean their teeth thoroughly with an electric toothbrush.
- Use a toothpaste that contains the right amount of fluoride, a natural mineral that helps protect against tooth decay.
- Floss your teeth or use interdental brushes regularly. It's best to do this every day, before brushing your teeth.
- Quit smoking.
- Visit your dentist regularly – at least once every 1 to 2 years, but more often if you need to.
