Children who have X and Y chromosome variations have more frequent dental problems. Those who have 47,XXY, in particular, often have a dental condition called taurodontism, which makes them more prone to tooth decay and other problems.
There is a possible relationship between bottled water, which typically does not contain added fluoride, and an epidemic of tooth decay in young children. Municipal tap water, on the other hand, is typically fluoridated and offers protection against tooth decay.
If your child drinks bottled water, and if you have no objections to fluoridated water, you may wish to consider shifting to tap water in a refillable water bottle. If you are concerned about the quality of your tap water, Consumer Reports recently published a comprehensive report offering a number of excellent choices for inexpensive, highly effective water filters – priced from $15, a cost that will be quickly offset by savings on bottled water, and you’ll be helping the environment in the process.
If you are concerned about bisphenol-A in some older plastic water bottles, there are numerous sources for inexpensive, BPA-free refillable water bottles. Here’s a link on Amazon for illustrations: amzn.to/HW7vBL
