Is it true that drinking lots of fruit juice gives you cavities?

A lot of fruit juice contains a lot of sugar.. one has to be careful.. fruit nectar and some fruit juices really have a lot of calories.. superior is flavoured water.. few calories and still tastes superior than just normal water.. Ice tea is bad also.. and lemonade.. one bottle of normal lemonade contains 18 teaspoonfuls of sugar.. therefore the only lemonade one can drink that contains no sugar is diet coke or water or flavoured water with a minimum of calories…and cranberry juice and OJ have less calories than other fruit juices..
