What is Chlorhexidine Mouthwash?

Chlorhexidine mouthwash is an antiseptic mouthwash that helps to treat and prevent gum problems, including gingivitis and mouth ulcers. It kills bacteria in your mouth, combating the cause of gum disease and treating it at the source.


What is gingivitis?

Gingivitis is an early stage of gum disease and it is a very common condition that most people will suffer with at some point in their lifetime. It happens when harmful plaque bacteria build up on your teeth and gums, causing irritation that leads to gum disease. Plaque can usually be removed by brushing, but a build-up can happen between the teeth and along the gum line. If you have gingivitis, you may notice some of the following symptoms:

  • Your gums bleed when you brush your teeth
  • Bad breath
  • Redness
  • Swelling
  • Soreness


How will this mouthwash help to treat my gingivitis?

This mouthwash uses the active ingredient Chlorhexidine Gluconate, which is an antimicrobial medication. This means that this mouthwash works as an antiseptic, killing the harmful bacteria in your mouth that cause gingivitis or gum disease and several other oral conditions.


What else can Chlorhexidine Gluconate be used for?

Some of the other conditions that Chlorhexidine Gluconate can help to treat include:

  • Mouth ulcers
  • Oral thrush
  • Denture sore mouth
  • As a mouthwash before dental surgery

Can I use this mouthwash if I am taking any other medications?

Should I brush my teeth after using this mouthwash?
