If you like to keep your breath fresh, or want to care for sore and inflamed gums, mouthwash is a great addition to your daily oral hygiene, along with flossing and brushing. Mouthwashes that contain fluoride will help reduce the acid that is produced by plaque bacteria. Dermacia stocks well known brands such as Listerine, Corsadyl and Aquafresh at our London pharmacy and from our online store.
