Ive heard that its bad to brush your teeth immediately after eating and that you should wait a half hour. T/F?

Somewhat true, if you eat/drink something very acidic (orange juice, sodas, etc) your enamel will be weaker afterwards and it might be better to wait a little while first, but not if this keeps you from brushing them. Generally, I have people brush first thing in the morning and before bed really well and if you want fresher breath after the meals, just run in and gently slap some toothpaste on your teeth and brush your tongue well. Also, try not to rinse after this, just spit, and do not rinse/eat/drink for at least 30 minutes and you also get a fluoride treatment which helps stregthen teeth. Most people rinse their toothpaste off which is good for small children, but adults need the fluoride to keep cavities away.Ive heard that its bad to brush your teeth immediately after eating and that you should wait a half hour.

False.


If you let that stuff sit on your teeth your teeth are going to absolb some of that. What you dont realize is that your teeth absorb fluids. The reason for saliva is digestion, but then you may ask why do you salivate if your not eating? The reason for that is because you have minerals in your saliva that help your teeth to remineralize when you have an incipient cavity. It also helps to flush away stuff that you do have in your mouth. Drinking Coke and sugary drinks isnt what you big concern is, they leave the oral cavity quickly and the saliva helps to wash away most of the sugars on your teeth. Its things like Jube Jubes and skittles or anything that actually STICKS to your teeth that you need to get off your teeth right away!
T. Some foods and drinks contain acid, like citric acid in fruit. This acid slightly melts the outer layer of your teeth, making it softer, which can then be brushed off with vigorous brushing. Thus, wait half an hour before brushing, especially for foods/drinks that are highly acidic.
