Can Pool Chlorine Harm Your Teeth?

What’s the Deal with Chlorine and Teeth?

Chlorine is added to pool water to kill bacteria and keep the water safe, which is great for swimmers, but not always so great for teeth. When chlorine levels in a pool aren’t properly maintained, the water can become overly acidic. This acidity may slowly erode tooth enamel, especially in people who swim regularly or spend long hours in the water each week (like competitive swimmers or lifeguards).

Signs of “Swimmer’s Calculus”

People who swim often in chemically treated pools can develop a condition known as “swimmer’s calculus.” This occurs when hard, brownish tartar builds up on the front teeth, typically due to prolonged exposure to improperly balanced pool water. Though not dangerous, it’s unsightly and requires professional cleaning to remove.

How to Protect Your Enamel While Swimming

✅ Keep your mouth closed: Try not to let pool water sit in your mouth while swimming.

✅ Rinse with fresh water: After your swim, rinse your mouth with plain water to wash away any residue.

✅ Fluoride protection: Using fluoride toothpaste or a maintenance rinse can help strengthen enamel and prevent erosion.

✅ Get regular cleanings: If you're in the pool often, regular dental checkups help spot and treat early signs of enamel loss.

✅ Schedule a cleaning for buildup removal: If you notice a chalky or brownish coating on your front teeth, especially before orthodontic treatment, your dentist can remove it easily in a quick and painless appointment. Schedule Here.
