It's a known fact that sugar consumption increases dental decay risk. Fruit juices are often considered a "healthy" choice and are often marketed as a good choice for kids because of the natural vitamins and in some cases even calcium. Juice also tastes good so kids tend to love it! However there is a direct link between fruit juice consumption and dental decay as well as weight gain in children. The American Academy of Pediatrics states that juices should be very limited for children younger than 7 years of age and those ages 7-18 should consume no more than 8 ounces of juice per day. It's also been noted that diluting the juice with water does not decrease the risk of dental decay as was previously thought. The American Academy of Pediatric Dentistry recommends parents avoid giving juice to toddlers at bedtime or in bottles or easily transportable, covered cups that allow them to consume juice easily throughout the day. Long story short, limit the amount of juice children are allowed to consume, avoid offering juice in bottles or sippy cups that would allow them to sip them all day and do not offer juice at bedtime.
