Tooth brushing

Brushing after meals can only be effective if it removes plaque. The object is to clean every accessible tooth surface, thus removing food debris and plaque and massaging the gum margin.

Toothbrushes with a small head and medium bristles are probably the most effective. The brush is rinsed and toothpaste added. Several strokes are used on each section of the mouth. Buccal, lingual, mesial and distal surfaces are cleaned by a rotary motion from gum to tooth. Occlusal surfaces are cleaned by a scrubbing action. Finally the gingival margins are cleaned by a backward and forward motion which must be done gently to avoid abrasion of the necks of the teeth.

Each jaw is done in turn¹ and the mouth is then thoroughly rinsed with warm water to expel food debris dislodged by the toothbrush. Brushes should be washed afterwards and allowed to dry.

Correct and effective tooth brushing in the way described requires time, knowledge and skill. Many people lack these requirements and brushing is ineffective as a preventive measure. The whole process can be made simpler for such people by using an electric toothbrush. Teeth are cleaned rapidly and effectively as most of the movements are done automatically. It is particularly valuable for children and the physically handicapped.

Notes

¹Each jaw is done in turn... — Кожна щелепа чиститься одна за другою
