Does brushing after eating sweets help prevent cavities? Surprisingly, the answer to that is no! To have a cavity one requires a tooth, some of the right kind of bacteria concentrated in an area where they can create and harbor acid on the tooth, sugar that the bacteria will eat and convert to acid, and some time for the acids to dissolve calcium out of the tooth enamel to make a hole.
So you see, if sometime during the day you cleaned all the bacteria off your teeth so they are not there to create any acid, then the sugar has no affect on the teeth. Also note: If bacteria have been successfully cleaned off the teeth, then it will take 24 hours for those bacteria to multiply and aggregate adequately to create and concentrate acid in a sheltered place on the tooth. In other words, your teeth are safe for 24 hours.
So THE TRICK here is to know how to effectively clean your teeth once each day to make them safe. Check our web site regarding disclosing solution as a tool to teach yourself effective tooth cleaning, and as a tool to monitor yourself periodically to verify you are still keeping your teeth safe.
Teach yourself to be a superb once a day effective tooth cleaner. And it makes absolutely no difference when during the day you do this cleaning.
