Uses for Periogard

Chlorhexidine is used to treat gingivitis. It helps reduce inflammation (redness) and swelling of your gums and decreases gum bleeding.

Gingivitis is caused by bacteria that grow in the coating (plaque) that forms on your teeth between brushings. Chlorhexidine kills the bacteria, which helps prevent gingivitis. However, chlorhexidine does not stop plaque and tartar from forming; proper tooth brushing and flossing are still necessary and important.

Chlorhexidine is available only with a prescription from your dentist or medical doctor.

Precautions while using Periogard

Chlorhexidine may leave a bitter aftertaste. Do not rinse your mouth with water right after using chlorhexidine, as this will make the bitterness worse. Rinsing may also reduce the effectiveness of the medicine.

Chlorhexidine may change how food tastes to you. This effect can last up to 4 hours after you use the oral rinse. Usually, this effect will become less noticeable the more you use the medicine. When you stop using chlorhexidine, your taste should return to normal.

Chlorhexidine may cause staining and increase tartar (calculus) on your teeth. Brushing with a tartar-control toothpaste and flossing daily may help reduce tartar build-up and staining. Additionally, you should see your dentist at least every 6 months for teeth cleaning and gum examination.

If you think a child weighing 22 pounds (10 kilograms) or less has swallowed more than 4 ounces of the dental rinse, get emergency help right away. If a child of any age drinks the dental rinse and shows symptoms of alcohol intoxication, such as slurred speech, sleepiness, or difficulty walking, get emergency help immediately.
