Chlorhexidine gluconate oral rinse, 0.12% provides antimicrobial activity during oral rinsing. The clinical significance of chlorhexidine gluconate oral rinse, 0.12% antimicrobial activities is not clear. Microbiological sampling of plaque has shown a general reduction of counts of certain assayed bacteria, both aerobic and anaerobic, ranging from 54-97% through six months use.

Use of chlorhexidine gluconate oral rinse in a six month clinical study did not result in any significant changes in bacteria resistance, overgrowth of potentially opportunistic organisms or other adverse changes in the oral microbial ecosystem. Three months after chlorhexidine gluconate oral rinse use was discontinued, the number of bacteria in plaque had returned to baseline levels and resistance of plaque bacteria to chlorhexidine gluconate was equal to that at baseline.

Chlorhexidine gluconate oral rinse, 0.12% is indicated for use between dental visits as part of a professional program for the treatment of gingivitis as characterized by redness and swelling of the gingivae, including gingival bleeding upon probing.

What To Expect When Using Chlorhexidine Gluconate Oral Rinse, USP 0.12%

Your dentist has prescribed chlorhexidine gluconate oral rinse, 0.12% to treat your gingivitis, to help reduce the redness and swelling of your gums, and also to help you control any gum bleeding.

Chlorhexidine gluconate oral rinse may cause some tooth discoloration or increase in tartar (calculus) formation, particularly in areas where stain and tartar usually form. It is important to see your dentist for removal of any stain or tartar at least every six months or more frequently if your dentist advises.

• Both stain and tartar can be removed by your dentist or hygienist. Chlorhexidine gluconate oral rinse may cause permanent discoloration of some front-tooth fillings.
• To minimize discoloration, you should brush and floss daily, emphasizing areas which begin to discolor.
• Chlorhexidine gluconate oral rinse may taste bitter to some patients and can affect how foods and beverages taste. This will become less noticeable in most cases with continued use of chlorhexidine gluconate oral rinse.
