It’s a bad idea to sip at any sweetened drink over an extended period of time. Although it’s a particular problem with coffee and tea, which many people linger over for most of the day. Nursing it introduces sugar into your mouth, creating a breeding ground for tooth decay. In fact it causes more damage than eating a giant piece of chocolate cake in five minutes!
Enjoy your cup of mocha java, just take it without sugar or drink it as quickly as possible!
