Scientists say we clean our teeth wrong way. Researchers from University College, London found that most of advice that dentists give us is very different. They add that we have been cleaning our teeth wrong way. researchers looked at tooth-brushing advice in dental textbooks, toothpaste instructions and dental clinics. They found five different basic ways of tooth-brushing and decided all of them were incorrect. Most of methods involve moving toothbrush along teeth, with brush moving round and round in small circular movements. researchers said we should stop doing this and use back-and-forth movement instead.

Aubrey Sheilam, lead author of study and professor of dental public health, said: "The public needs to have sound information on best method to brush their teeth." The research suggests not brushing teeth too much. More than twice day damages enamel on teeth. The recommended time for brushing is no longer than three minutes each time. research also says using too much pressure and brushing your teeth too hard will also damage teeth. Researchers also advised not cleaning your teeth immediately after eating. This is when acid is strongest in your mouth and this acid will damage teeth. final recommendation was to clean tongue too because it also has lot of bacteria.
