Only brushing is not enough to maintain oral hygiene. Its mandatory to go for a cleaning treatment of your tooth known as Scaling. Its done only in a Dental Clinic
and is recommended to go for the same once in a year along with brushing, flossing and mouthwashing of your teeth and gums on a regular basis. So do visit a Dental clinic. Till then can use Stolin GA (gum astringent) twice daily on your gums by applying it for 2 minutes and washing off with water. Its effect will be more after Cleaning and polishing.
