This is a very misunderstood idea. Hygiene is usually used to describe the cleaning and disinfection of the surfaces of all teeth and the oral tissues surrounding the teeth and lining the oral cavity, throat, tongue, and palate. This is commonly and effectively treated using a manual or powered toothbrush and then an oral rinse once per day. Preferably in the morning.
There are literally over 100 products that are on display at the oral care center at each pharmacy. From oral rinse to electric toothbrushes, Waterpik® units, tongue scrapers, gum massaging tools, floss (of many kinds), tiny brushes to clean areas between the teeth, and many more. So that any patient or member or the public can look for and find any small devices or tools to achieve a very high level of oral hygiene on a daily basis.
