Is Swimming in a Pool Bad for Your Teeth?

Is your family excited to hit the local pool this summer? Swimming is one of the best ways to cool down in hot weather – it’s also a great form of exercise for both children and adults! However, it may surprise you to learn that this fun activity can have adverse effects on your oral health. Read on to find out how it can be bad for your teeth and what you can do to protect your smile this season.

The Effects of Swimming on Your Oral Health

Most people love to spend their summer days at the pool. Unfortunately, spending too much time in the water can put your oral health at risk. Here are a few ways swimming can affect your mouth:

Swimmer’s Calculus

The longer your teeth are exposed to chlorinated water, the more likely you are to develop swimmer’s calculus. After constant exposure, the chlorine can deposit a residue on your teeth and turn them yellow or brown. Typically, this condition only affects swimmers who spend more than six hours a week in treated water. If you notice any of these stains on your or your children’s teeth, let your dentist know as they can remove them with treatments and frequent cleanings.

Tooth Sensitivity

If you have a pool at home, make sure you get the chlorine levels checked by a professional to ensure they’re within the recommended range. Improperly chlorinated pools can wreak havoc on your teeth, causing enamel erosion and leaving your teeth feeling brittle and sensitive.

Tooth Squeeze

Are you a diver or snorkeler? You may be at risk for “tooth squeeze”, also known as barodontalgia. This condition usually occurs in extreme altitudes, such as deep water. The air inside your teeth contracts to match the outside pressure, causing significant discomfort and damage to fillings, crowns, and dentures. Before your next dive, schedule a visit with your dentist and ask them to check your mouth for signs of decay or loose restorations.

Mouth Injuries

Participating in high-contact sports, such as swimming, water volleyball, and water polo, increases your risk for teeth, gum, and jaw injuries. Prevent these accidents by wearing a properly fitted mouthguard whenever you play! They’ll protect your smile from impact and minimize damage.

Tips for Protecting Your Smile

Even though swimming can be harmful, you don’t have to give it up completely! Here are some tips for keeping your pearly whites safe:

  • Look for signs of acid eating away at surfaces around the pool (your teeth will be affected the same way)
  • Test pool water with pH strips to ensure it’s properly chlorinated
  • Keep your mouth closed while swimming to minimize chlorine exposure
  • Attend routine checkups to catch, prevent, and treat enamel erosion as early as possible

Your oral health might be the last thing on your mind when you go for a swim – but it should be a priority. By following these tips and taking proper precautions, you can maintain a strong, healthy smile all season long!

I've been coming to this practice for years now since moving to the Raleigh area. The office is always clean and organized and the staff have always been friendly and communicative. Also, the TV's mounted to the ceiling are a nice touch! I've been seeing Dr. Laster for several years before our insurance changed causing me to change to Dr. Rensch. Both are so easy to talk to and always made me feel at ease.

From beginning to end 5/5! I thought I was experiencing a dental 911. I submitted an inquiry at 11:30pm and by 8am the next morning, Deidra (front office staff) was already leaving me a message. She was so sweet and patient at 8am lol. After our initial conversation, I informed all follow up dentists “I found my dentist office” but thank you so much! Today I was welcomed with the same energy from Diedre to Britany then finally Dr.Wrench. The music playing throughout the office was fantastic; ie music selection and volume. The TV’s on the ceiling and wall made my procedure so painless and enjoyable! I watched an entire Christmas movie lol! Dr. Wrench (apologies for spelling) made my teeth absolutely perfect! I left telling my friends and family I have a million dollar smile! 😊 I can tell he wanted them perfect and he did! Thank you all so much for being amazing! Sincerely, Your next patient.

Dr. Laster and Dr. Rensch go above and beyond for their patients. I have seen both for various treatments and I always feel comfortable and heard. They take time to listen and to talk with you. They explain your options and work with you to develop the best plan for your care. They are always upbeat and positive and you can tell they truly love what they do. The front desk staff is exceptional as well. Deidre is so caring and very sweet. She’s efficient, understanding and conscientious of your time. I highly recommend.

Connections Dentistry was great! The staff is so friendly and truly cares about their patients. My appointment was quick, and honestly the best dental experience I’ve had. They are great about offering helpful solutions without making you feel like you are being reprimanded… which was the reason I was putting off the dentist. 100% recommend!
