Pool Season & Your Teeth: What Chlorine Can Do to Your Enamel

Summer means sunshine, flip-flops, and time in the pool—but while you’re cooling off, your teeth may be soaking in more than just fun. At CarolinasDentist, with 14 locations across North Carolina, we see more patients this time of year with enamel changes linked to frequent pool exposure. Yes, chlorine can affect your teeth, especially with repeated or long-term contact.
How Chlorine Interacts With Tooth Enamel
Chlorine keeps pool water clean, but it also affects the water’s pH. When pool water becomes too acidic, it can start to erode enamel—the protective outer layer of your teeth. This usually happens in pools where chlorine levels aren’t properly balanced.
Swimmers who spend hours in the water every week may start to notice sensitive spots, staining, or a yellowish tint. That’s because worn enamel exposes the darker dentin beneath. Competitive swimmers are especially prone to this, but even regular pool-goers can be affected over time.
Who’s Most at Risk?
People who swim daily—or spend long sessions with their mouth open underwater—have more direct exposure. Kids at swim camp, adults doing laps, and lifeguards all fall into this category. That said, even occasional swimmers should be aware, especially if they notice sudden tooth sensitivity during the summer months.
What You Can Do About It
Rinse your mouth with fresh water after swimming. Don’t brush immediately, as enamel can be slightly softened by pool exposure—give it 30 minutes. If you’re a frequent swimmer, using a fluoride toothpaste or professional fluoride treatments can help strengthen enamel between visits.
