Common health mistake -2
The Problem: We've been told to brush our teeth after meals, and of course it is true you should at some point. However, when you drink something like coffee or orange juice, the acidity levels in your mouth go through the roof. If you rush off to brush your teeth afterwards, before your saliva had time to neutralize the PH levels, you'll be actually pushing the acid into the enamel of your teeth, causing erosion. A study conducted in 2004 found that those who brush within 20 minutes of eating breakfast lost more dentil (the layer underneath the enamel) than those who waited.
The solution: After drinking an acidic beverage such as soda, wine, coffee or a fruit juice, drink a glass of water and wait 20-30 minutes before brushing, that will give enough time for the saliva in your mouth, which has a PH of 7, to neutralize the acidity. more
