How to use a Manual Toothbrush
Start with your upper teeth, working on both the outer and inner surfaces. Position your toothbrush at a 45-degree angle towards your gums—you should feel the bristles gently tickling the gum line, where plaque accumulates most.
Now comes the most important step: turn the brush away from the gums towards the tooth surface, as if you're painting the tooth. Use this sweeping, rolling motion from gum to tooth on both the outer (cheek side) and inner (tongue/palate side) surfaces, as this technique effectively removes plaque while protecting your gums from damage. The inside surfaces of your lower front teeth are notorious spots for rapid calculus (tartar) buildup, so to clean these areas properly, hold your toothbrush vertically so it fits better against the narrow inner surfaces of your front incisors, using the same paint-brushing, sweeping motion from gums to tooth surface. For the outer surfaces of your front teeth, hold the toothbrush horizontally and repeat the technique. If the mirror is covered in toothpaste splatters, you've done it right!
When it comes to reaching the outer surface of upper molars - you need to almost close your mouth, shift your chin slightly to the side you're brushing, and then perform the sweeping motion. This positioning creates more space and better access to thoroughly clean those areas, ensuring optimal oral health.
