Most of us learned to brush our teeth when we were children, and we have stuck with (to stick with something= continue doing something) the same brushing technique into adulthood. Unfortunately, many of us learned how to brush the wrong way. And even if we learned the right way, we might not always stick to (continue doing) it.
Different dentists give us different advice (opinion; suggestion; recommendation). Researchers looked at recommendations in dental textbooks, toothpaste instructions and dental clinics. They found five basic ways of tooth-brushing. Most of them moved the toothbrush along the teeth in circular movements. The researchers said we should stop this. We should move the toothbrush backwards and forwards instead.
A professor of dental public (for all people) health said we need good information on how to brush our teeth. We should not brush our teeth more than twice a day. This damages the tooth enamel. We should brush for two to three minutes each time and not press too hard. In addition, we shouldn’t clean our teeth minutes (very soon; immediately) after eating. This is when the acid in your mouth can damage your teeth. We should also clean our tongue. This also has a lot of bacteria.
