Don’t brush after eating?

Am I serious?  Don’t brush after eating?  Yes, recent research shows that brushing too soon after meals, especially after eating acidic foods and drinks, can be harmful to the teeth.  Brushing after an acid reflux episode can also damage the teeth.  Acid attacks your teeth; it erodes enamel and the dentin.  And brushing can accelerate the process of erosion.  Brushing can push the acid deeper into the enamel and dentin layer.  Researchers recently examined the effect of tooth brushing after subjects drank diet soda. There was an increase in dentin loss when brushing took place within 20 minutes after drinking the soda.  But there was less tooth wear when brushing took place 30-60 minutes later.  The conclusion is that to protect the dentin, people should wait at least 30 minutes to brush their teeth after drinking or eating acid.  To remove acid, it is better to rinse out the mouth with water or an acid-neutralizing mixture: one part baking soda to eight parts water.
