Chlorhexidine has powerful antibacterial properties, and can be especially helpful in maintaining a healthy mouth after a teeth deep cleaning procedure such as tooth scaling and root planing. This rinse also helps to control and kill the bacteria in your mouth that cause gum disease.
Chlorhexidine mouthwash can cause brown stains on teeth, because chlorhexidine has been shown to bind to both hard and soft tissues. So if your dentist prescribes a chlorhexidine wash for a short time while you're recovering from gum disease treatment, try not to drink too much coffee, tea, red wine, or consume any foods that may be likely stain your teeth. Also, chlorhexidine mouthwashes may not be the best choice if you have tooth crowns or caps made of composite or glass ionomer, as these materials may stain.
In general, it's not necessary to make a chlorhexidine mouthwash a long-term part of your oral care routine, and even a prescription antibacterial mouth rinse does not replace toothbrushing and flossing. Once your gum disease is under control, following a regular program of dental hygiene that includes twice-daily toothbrushing, daily flossing and regular visits to your dentist should help to prevent further problems with gum disease.
