Never brush your teeth straight after a meal as it can damage your teeth, especially if you've had fruit, fizzy drinks, wine or any other food that contains acid.

Hoax or Fact:
Circulating messages suggest people not to brush their teeth immediately after eating certain foods, as it can damage the enamel of their teeth. Yes, it is a fact.
The messages actually refer to sugary and acidic foods and drinks like chocolates, acidic fruits and fizzy drinks, because in these cases, the sugars present in the food feed bacteria in your mouth, and along with those acids weaken and soften your gums and the enamel of your teeth temporarily. So when you brush your teeth straightaway after eating such foods, it can brush away the enamel of your teeth and minerals that protect your gums and teeth.
To avoid this danger, after you eat such food stuffs, it is better to swish your mouth with water, wait for about 30 minutes and then brush your teeth. Because at this point, the softening of your teeth shall be reversed by itself naturally, with the help of the saliva in your mouth. To a related question as to when to brush teeth, the same is suggested in Mayo Clinic website:
In choosing when to brush your teeth, you might also consider your diet. If you've eaten an acidic food or drink, avoid brushing your teeth for at least 30 minutes. These acids weaken tooth enamel, and brushing too soon can remove enamel. If you know you're going to eat or drink something acidic, brush your teeth beforehand.
