Corsodyl Treatment Mouthwash is an intensive treatment that's clinically proven to help treat the early signs of gum disease, (gingivitis). It's important to act fast to treat the symptoms of gingivitis, like bleeding, red or swollen gums. This can help stop it from developing into the irreversible second stage of gum disease, periodontitis, which can, eventually, cause tooth loss. It is designed to be used as a short-term solution alongside a good daily oral care routine. You may also use it to help gums heal after dental surgery. Corsodyl Treatment Mouthwash contains 0.2% of the active ingredient chlorhexidine digluconate. This works to kill the plaque bacteria which can irritate the gums and cause gum disease. The active ingredient, chlorhexidine digluconate acts rapidly, to kill the bacteria that cause plaque within 30 seconds. It also forms a protective antibacterial layer over the teeth and gums to prevent plaque build up for up to 12 hours.
