When summer hits, the pool becomes a go-to spot for relaxation, fun, and staying cool — whether you’re a kid, a teen, or an adult. But did you know that frequent swimming, especially in chlorinated pools, can actually affect your teeth?
At Downtown Sleep Dentistry & Oral Surgery, we treat smiles of all ages — and we’re here to share something that might surprise you about how chlorine interacts with your dental health.
So… How Does Pool Water Affect Teeth?
Most pools are treated with chlorine to keep the water clean, but if the chemical levels aren’t balanced properly, the water can become too acidic. Over time, regular exposure to acidic water can slowly wear down your enamel, the outer layer of your teeth that protects against sensitivity, decay, and discoloration.
People who swim often — especially those who train or spend long hours in the pool each week — are most at risk of this type of wear.
Have You Heard of “Swimmer’s Calculus”?
This isn’t something from math class. Swimmer’s calculus is a hard, brownish tartar that can form on the front teeth due to prolonged exposure to pool water. While it’s not harmful, it can be stubborn to remove at home and usually requires a dental cleaning.
It’s most common in frequent swimmers — but we’ve seen it in people of all ages who spend a lot of time in chlorinated water.
Signs Pool Water Might Be Affecting Your Teeth
If you or your child is a regular swimmer, keep an eye out for:
- Increased tooth sensitivity
- Yellowing or dark spots on the front teeth
- A rough or gritty feeling near the gumline
- Dry mouth or changes in how your teeth feel after swimming
Easy Ways to Protect Your Smile
No need to stay out of the pool — just take a few simple steps to minimize the effects of chlorine:
- Keep your mouth closed while swimming, especially underwater
- Rinse your mouth with fresh water after swimming (or brush, if you can)
- Schedule regular cleanings — especially during or after swim season
- Talk to your local pool staff about pH and chlorine balance if you swim often
