People often get into a bad routine as a child, and then stick with it for a long time until they encounter problems or pain.
So, make sure you never brush your teeth within thirty minutes of eating or drinking, as this damages the enamel of your teeth.
You wouldn’t pour acid onto your brand new car and then start brushing it into your lovely new paintwork. That’s the equivalent of brushing your teeth straight after eating or drinking.
You need to give your saliva some time to neutralise those acids and protect your teeth. The night time brush is even more important than the morning brush, don’t get lazy and leave your food eating away at your teeth all night.
Don't be this guy.
