Chlorhexidine Dental Rinse: What It Is and Why Dentists Recommend It

When it comes to maintaining good oral hygiene, brushing and flossing are essential—but sometimes, your dentist might prescribe a little extra help. One such tool is chlorhexidine dental rinse, a powerful antimicrobial mouthwash that’s commonly recommended for patients with gum problems or those recovering from dental procedures.

What Is Chlorhexidine?
Chlorhexidine gluconate is an antiseptic used in a variety of medical and dental settings. As a dental rinse, it's typically available in a 0.12% or 0.2% concentration and works by killing bacteria that cause gingivitis (gum inflammation), plaque buildup, and bad breath.

When Is Chlorhexidine Prescribed?
Dentists may prescribe chlorhexidine rinse in cases such as:

Gingivitis or periodontitis

After dental surgeries like extractions or implant placements

Mouth ulcers or infections

For patients who have difficulty brushing due to disability or illness

It’s often used for short-term management, typically 7–14 days, depending on the condition.

How to Use Chlorhexidine Rinse
Use as directed, usually twice a day after brushing.

Do not rinse with water, eat, or drink immediately after use (wait about 30 minutes).

Avoid toothpaste 30 minutes before or after use—it can reduce effectiveness.
