Chlorhexidine (pronounced klor-HEX-i-deen) is used to treat bacterial gum disease (gingivitis). It works by killing or inhibiting the growth of bacteria, helping reduce gum inflammation. This medication may also be used for other purposes. Consult your healthcare provider or pharmacist if you have any questions.

You can also find products like Stim Periex Chlorhexidine Mouthwash and ICPA Wet Mouth Mouthwash to help manage oral hygiene and prevent gum disease. These brands like ICPA and Stim mouthwashes are effective in maintaining oral health, and are commonly used alongside other dental cements used in dentistry like Calcium Hydroxide in Dental Cements are also effective.

For easy access to dental care products, explore the medical app or medical equipment app for a wide range of dental supplies.

Chemical properties of Chlorhexidine

Chlorhexidine mouth rinse is a broad-spectrum antimicrobial agent known for its ability to kill or inhibit the growth of a wide range of bacteria, fungi, and viruses. It has a strong positive charge, allowing it to bind to negatively charged oral surfaces, such as teeth and gums, where it forms a protective layer. This binding action helps to reduce plaque buildup and inflammation in the gums.

Benefits of using Chlorhexidine Mouthwash

Chlorhexidine mouth gargle effectively targets the bacteria in the mouth that cause gum disease, making it a powerful antiseptic mouthwash. It is often prescribed by dentists to treat the inflammation, swelling, and bleeding associated with gingivitis.

How to Use Chlorhexidine Mouthwash?

  1. Use immediately after brushing and flossing your teeth. Make sure to rinse all toothpaste from your mouth beforehand.
  2. Follow the directions on the prescription label. Use the cap from the original container to measure the dose. If you do not have the cap, ask your pharmacist for a suitable measuring device.
  3. Swish the mouthwash in your mouth for 30 seconds. Do not swallow it.
  4. Use the mouthwash at full strength, without diluting it with water.
  5. Avoid eating or drinking for several hours after using the rinse to ensure maximum effectiveness.

Flavour: Chlorhexidine mouthwashes come in various Flavors like mint, lemon, or alcohol-free options. Choose one that suits your taste preferences and comfort level, especially if you have sensitivity to strong Flavors.

Intended Use:
