Is Brushing Teeth After Eating Good For You?

When you eat, plaque (a sticky, white biofilm) forms on your teeth. Plaque contains bacteria. According to the Indian Dental Association, cavity-causing organisms feed on sugar and turn it into acid, which attacks tooth enamel and causes tooth decay. If you don’t brush and get rid of this plaque build-up regularly, the acid that gets produced will break down your enamel, resulting in cavities.

Plaque that isn’t removed can harden into tartar. When tartar builds up on your gums, it can cause inflammation, and if untreated, gum disease.

Not necessarily! Brushing your teeth after eating can sometimes affect your tooth enamel. In fact, the Mayo Clinic warns that if you’ve consumed foods containing citric acid, like oranges, grapefruits, and lemons, brushing too soon can be bad for your teeth. Why? Because these acidic foods weaken tooth enamel and brushing too quickly can remove the enamel.

According to Hindustan Times, brushing your teeth within half an hour of eating a meal or drinking a cup of coffee could seriously damage them, dentists have warned. This gives your saliva a chance to naturally wash away food particles, so your mouth returns to its proper pH level. It's best to stick to drinking water or chew sugarless gum while waiting for this to happen.

Yes, it is! What’s important is that you ensure you brush sometime after your last meal and before you go to bed. If you go to sleep without brushing, you’re allowing plaque to build up, attack the tooth enamel, irritate the gums and harden on and between your teeth and at the gumline. So whether you decide to brush an hour after you eat dinner or brush right before you sleep, it's important to brush effectively at the gumline and on all surfaces of the teeth.

Does this mean you shouldn’t brush your teeth after your meals? Now that you have all the information, it’s up to you. Only one is certain: if you give your teeth and gums two whole minutes of brushing and flossing twice a day, you’ll be able to seize each day, armed with strong teeth and a fresh and healthy mouth!
