Brushing Before or After Meals?

It’s often a controversial question that sparks some debate! Do you brush before or after meals?

It often depends on your perspective. As Trisha O'Hehir, a senior consulting editor of the Registered Dental Hygienist Magazine (RDH) points out in her article on the very subject; she believes that there is a gap between research and reality, because dental professionals are concentrating on the effects of plaque, whereas everyone else is just concerned about having spinach or other bits of food stick between their teeth!

From a dental hygiene perspective we’d recommend brushing BEFORE eating. Yes, I know that that morning glass of orange juice tastes disgusting after you’ve cleaned your teeth! But believe us there is a good reason why it's worth it…

Plaque bacteria on your teeth will instantly react with food that you eat to produce acid. This acid softens your tooth enamel. The logic is that brushing your teeth before eating will remove most of the plaque, therefore less acid is produced. The problem dental professionals often see is that softened dental enamel can literally be scrubbed off when your teeth are brushed straight after eating. So we see damage to teeth, even in people who don’t eat a lot of sugar.

It’s a good idea to drink water and swill your mouth out after eating to try and dislodge any food particles. If you do brush after meals to remove food then wait at least 30 minutes for the acid levels to return to neutral.

One final thought the RDH article leaves us with is “Since soda and alcoholic drink consumption in the evening is a common practice, both in England and the United States, it makes more sense to brush when you get home from work, before having dinner, rather than after softening the enamel with acidic foods and beverages.”
