You don’t have to give up soft drinks. As a matter of fact, it doesn’t have to do with the quantity of soft drinks you consume, either. It’s the duration of the exposure in the mouth. So, if you’re sipping slowly and savoring every sip, that’s worse than if you drink it quickly.
Always remember that by taking a sip of tap water, you reduce the damage done to your teeth. So, keep the tap water handy.
