Your teeth are important in many ways. If you take care of them, they will help take care of you. Strong, healthy teeth help you chew (bite the food in your mouth several times) the foods to help you grow. They help you speak clearly. And yes, they help you look your best. Despite its importance (We know it is important but), most of us have never learned how to brush our teeth the right way. We learned to brush our teeth when we were children, and we have stuck with the same brushing technique into adulthood. And even if we learned the right way, we might not always stick to it.
Brushing correctly is tricky, and is not just for a whiter smile and fresher breath, it is important for several reasons . First and foremost (most important), a toothpaste and a correct brushing action work to remove plaque (a layer of bacteria or bits of food that forms on your teeth). Second, toothpaste contains fluoride, which makes the entire tooth structure more resistant to (not damaged by) decay. Third, special ingredients (substances) in toothpaste help to clean and polish (make them bright and shiny) the teeth. Fourth, toothpastes help freshen breath and leave your mouth with a clean feeling.
Researchers from University College, London found that most of the advice that dentists give us is very different, and mostly wrong. The researchers looked at tooth-brushing recommendations in dental textbooks, toothpaste instructions and dental clinics. They found five different basic ways of tooth-brushing and decided (made the decision; concluded) all of them were incorrect. Most of the methods involved moving the toothbrush along the teeth, with the brush moving round and round (repeatedly; over and over) in small circular movements. The researchers said we should stop doing this and use a back-and-forth movement instead.
Aubrey Sheilam, lead author of the study and professor of dental public health, said: “The public needs (people need) to have sound (complete; good; sensible) information on the best method to brush their teeth.” The research suggests not brushing teeth too much, more than twice a day damages the enamel on the teeth. The recommended time for brushing is no longer than three minutes each time. The research also says using too much pressure and brushing your teeth too hard will also damage teeth. Researchers also advised not (said you should not be) cleaning your teeth immediately after eating. This is when acid is strongest in your mouth and this acid will damage teeth. A final (last) recommendation was to clean the tongue too, because it also has a lot of bacteria.
