The correct way to brush your teeth
Place the toothbrush at 45 degrees to the margin of the gums and brush gently in a short back-and-forth motion.
For the inner surface of the upper and lower front teeth, the toothbrush should be tilted vertically and used in up-and-down strokes.
Do not brush horizontally along the gum line – this can cause the gum to recede.
When and how often to brush your teeth
Brush your teeth at least twice daily, in the morning and at night before you sleep, for at least two minutes each time. It is important to wait at least 30-45 minutes after a meal before you brush your teeth. This is because food reduces the pH level in the mouth. When the pH level drops, your mouth becomes acidic and brushing teeth at this time can remove enamel. Saliva in the mouth will gradually clear out the acid and restore the pH level.
A manual and electric toothbrush should be changed every three months or earlier if the bristles are frayed.
Tips for good oral hygiene
Use fluoride toothpaste as it’s been proven to help prevent tooth decay.
Make it a daily habit to floss or use an inter-dental brush to remove bacteria and food debris in between teeth and under the gum line. These can accumulate to form plaque.
Avoid frequent snacking on food or drinks high in sugars or acid. Limit between-meal snacks to two a day.
Visit a dentist regularly so that dental problems can be detected and treated promptly.
Get your teeth professionally cleaned at regular intervals.
