In what way can I replace calcium supplements to maintain strong bones and teeth if I don't drink milk very much?

Yes and no. Yes for bones, no for teeth. Discuss this issue with your own physician regarding need and amount. Once teeth are formed and erupted, calcium supplements have absolutely no effect on tooth enamel and strength.
Yes. Calcium is very important to our bodies not only for bones but also for heart function, muscles and the nervous system. Women need at least 1, 000 to 1, 500mg mg a day. If you are not getting this much in your diet then it is important to take supplements. It is also important to take vitamin d and magesium.
