Chlorine is a necessary and effective way to kill harmful bacteria in drinking water and swimming pools. But you may be wondering, "is chlorine bad for your teeth?" We'll break down the potential risks of chlorine on your oral health and let you know how to protect yourself so you can continue smiling.
According to the American Chemistry Council, before chlorine was used in drinking water to kill disease-causing germs, waterborne diseases killed thousands of people every year.
In pools and hot tubs, chlorine and pH are the first defense against hazardous germs that can make you sick with recreational water illnesses that cause symptoms like:
The chlorine included in your tap water is generally not enough to cause any dental problems, but soaking in a backyard jacuzzi or doing laps at your local swimming pool regularly could have negative effects on your tooth enamel.
Chlorinated pools and hot tubs contain pH levels that can cause enamel erosion on your teeth. Of course, it's unlikely that you swim with your mouth open (if you do, don't), but water tends to seep into your mouth occasionally. A few visits to the local pool a year is unlikely to have any adverse effects. Still, if you swim laps daily or soak in a hot tub every night, the possibilities of enamel erosion on your teeth are real – particularly if you over-chlorinate your pool. The CDC recommends the pH levels of treated water to be between 7.2 and 7.8. The free chlorine concentration should be at least 1 part per million in pools and at least 3 parts per million in hot tubs.
If you notice any of the following symptoms after frequenting chlorinated bodies of water, your tooth enamel may be wearing away (what's called swimmer's calculus). Your teeth may:

The pH level of water is invisible to the naked eye, so here are some tips to help you know if it's safe to take a dip:
By taking these precautions when you swim in chlorinated pools and limiting how often you swim or relax in chlorinated water, you can significantly reduce your risk for enamel erosion. If you're an avid swimmer, be conscious of how much water gets in your mouth. And practice good oral hygiene for an even greater chance to withstand the effects of chlorine. Brush at least twice a day, and don't forget to brush your tongue. Consider using a toothpaste that helps replenish natural calcium to strengthen your tooth enamel. And be sure to see your dental professional for regular appointments so they can catch any developing erosion early. When you do all of this, caring for your oral health should go swimmingly.
