Summer means more time in the pool, and there’s nothing better than a long swim on a hot day. But most swimmers likely don\u2019t think about what all that pool time is doing to their teeth. While stains and discoloration are a concern, teeth whitening<\/a> can fix that issue. Where it gets dangerous is enamel erosion. Keep reading to see how pools affect teeth and learn what you can do to protect your smile.<\/p>\n\n\n\n\n\n\n\n

What\u2019s the Deal with Pool Water?<\/h2>\n\n\n\n

Swimming pools are treated with chlorine to keep the water clean and safe, but it\u2019s not the chemical itself that does the most damage. The real culprit is the pool’s pH level. Properly maintained pools are kept at a slightly alkaline pH around 7.2 to 7.8. This is pretty close to neutral, so it poses little risk to your enamel. However, when pools aren\u2019t looked after carefully\u2014whether residential, commercial, or public\u2014the pH can drop into acidic territory.<\/p>\n\n\n\n

When this happens, it can gradually erode tooth enamel over time\u2014a condition sometimes called “swimmer’s erosion.” While it won\u2019t happen just because you spent a few hours in the pool one weekend, regular, prolonged exposure to improperly balanced water adds up.<\/p>\n\n\n\n

Chlorine and Tooth Staining<\/h2>\n\n\n\n

Even in properly maintained pools, chlorine can cause surface staining over time. Swimmers who spend a lot of time in the water may notice a yellowish-brown tinge developing, sometimes called “swimmer’s calculus.”<\/p>\n\n\n\n

This type of staining tends to accumulate on the front teeth and can be stubborn to remove with brushing alone. Professional teeth whitening is often the most effective way to address it once it develops.<\/p>\n\n\n\n

What About Saltwater Pools?<\/h2>\n\n\n\n

Saltwater pools are a popular alternative, and many swimmers assume they’re automatically gentler on teeth. Saltwater pools do still use chlorine\u2014they just generate it differently through a saltwater system. The pH concerns are similar, so the same measures need to be taken regardless of the pool type.<\/p>\n\n\n\n
