The Dangers of Pool WaterSwimming pools are often sanitized using a combination of chemicals, including chlorine. This chlorine helps keep harmful bacteria from swimming around in your pool water and protects you and your family. It also plays a role in the water’s pH level. However, if proper balance isn’t maintained, your pool water could put your teeth at risk.
Pool water should be kept at a safe pH level at all times — usually between 7.2 and 7.8. If the pH drops below this safe zone, it becomes acidic and can cause eyes to burn, skin to become irritated, and tooth enamel to erode.
Acidic Water and Enamel ErosionEnamel is the hard coating surrounding each tooth’s surface and protects teeth against bacteria, decay, and sensitivity. It’s one of the hardest materials in our bodies, but that doesn’t make it unbreakable. Enamel can erode due to a diet high in acid, brushing too hard, or yes, swimming in a pool with a low pH. Of course, those who spend a lot of time in the pool like competitive swimmers are at greater risk for this type of enamel erosion.
This correlation between pool water with a low pH and enamel erosion dates back to the 1980’s. In fact, one study showed that nearly 40% of competitive swimmers had some level of enamel erosion. Continued research appears to support the notion that pool water may, in fact, put tooth enamel and oral health at risk.
