Putting aside video games and Netflix marathons in favor of enjoying all things outdoors wins in the court of popular opinion. But before you send your family packing to the water park or push them out the door for a nature hike, complete with tree climbing and rope swinging, take heed.

The ADA and Massachusetts Dental Society @MassDenta both offer preventative suggestions and emergency options to guide you on the right path.

According to www.massdental.org:

Excessive exposure of the tooth enamel to chlorine, a chemical added to disinfect pools, may cause brownish discolorations, primarily on the front teeth. These discolorations are due to chemical additives in the chlorine, such as antimicrobials, which give the water a higher pH than saliva, causing salivary proteins to break down quickly and form organic deposits on the swimmer’s teeth, according to the Academy of General Dentistry (AGD).

Swimmers—especially those who are in the pool for more than six hours a week—can avoid this staining by brushing their teeth immediately after swimming.

But because swimming pool accidents are the number one cause of dental emergencies during the summer, according to the AGD, it’s always best to be prepared.

ADA.org suggests a simple precaution you can take to avoid accident and injury to the teeth: Wear a mouthguard when participating in sports or recreational activities.

For a knocked-out permanent or adult tooth, keep it moist at all times. If you can, try placing the tooth back in the socket without touching the root. If that’s not possible, place it in between your cheek and gums, in milk, or use a tooth preservation product that has the ADA Seal of Acceptance. Then, get to your dentist’s office right away.
