Don't Brush!

At least NOT if you have had soda, wine, coffee, tomatoes or any citrus fruits. Did you know that a study say that actually brushing your teeth after an intake of acidic foods can push the acid into your tooth enamel even further? This can then a result that leads to sensitivity and unsightly erosion and can cause more cavities at worst!
What you do instead is to have a swish of water, then wait at least 30 minutes to 1 hour before brushing your teeth.

One helpful tip, isn't it?
