Is it ok to put fresh pure cranberry juice and lime juice in my water? is it safe in water or can it still destroy my teeth ?

Food Myths: Yes, it is safe and common practice throughout the world to do this.

Safe but...: Remember that decay producing bacteria thrive in an acidic environment. It may be safe to dilute juice with water, or place a small amount of juice in water as a preservative and for taste, but remember you are making it easier for "bad bugs" (bacteria) to infect the teeth (cavities).
