Oral hygiene is the practice of keeping one's mouth clean and free of disease and other problems (e.g. bad breath) by regular brushing of the teeth (dental hygiene) and cleaning between the teeth. ... To improve the appearance of their teeth, people may use tooth whitening treatments and orthodontics. Personal hygiene is how you care for your body. This practice includes bathing, washing your hands, brushing your teeth, and more. Every day, you come into contact with millions of outside germs and viruses. They can linger on your body, and in some cases, they may make you sick. Personal hygiene practices can help you and the people around you prevent illnesses. They can also help you feel good about your appearance. This day was celebrated with personals from a international volunteer organisation coming and giving information with the students teachers and parents. They demonstrated hand washing techniques. This took place on 11th August 2015.
