Living in Singapore likely means you and your family spend a lot more time in the pool. While swimming year-round can be great, we often overlook the impact it can have on our dental health. Pool water, especially if it’s highly chlorinated, can potentially lead to enamel erosion, causing tooth staining, sensitivity, and an increased risk of cavities over time. To help us understand the best ways to protect our teeth, we spoke to USA certified dentist, Dr. Josh Liu from Expat Dental.
Chlorine and Its Effects on Dental Enamel
Chlorine is a necessary disinfectant in pools and water play areas. However, when too much chlorine is added to pool water, it can lower the pH, making the water more acidic. When the pH level of pool water falls outside the ideal range of 7.2 – 7.8, it can become corrosive to dental enamel – the hard, protective outer layer of your teeth.
Dental enamel protects against decay and damage to your teeth. While this protective layer is known for being the hardest substance in the human body, it is not impervious to damage and does not regenerate. This makes it crucial to recognise the signs of enamel erosion early so you can limit your exposure.
Who’s at Risk of Dental Erosion from Pool Water?
Dental erosion from pool water can affect anyone who spends extended periods in the pool, such as:
- Competitive/Frequent Swimmers: Those who swim for 6+ hours a week.
- Children and Adolescents: Younger individuals often have more porous enamel, making them more susceptible to erosion from acidic environments. They also tend to keep their mouths open while swimming or frequently ingest pool water.
- People with Inadequate Oral Hygiene Practices
- Those Consuming Acidic Foods/Drinks: People who consume a diet high in acids (such as soda or citrus fruits) may increase the risk of erosion.
- Individuals with Existing Dental Issues: Those with pre-existing dental problems, such as enamel hypoplasia or acid reflux.
Signs Your Teeth Might Be Suffering From Too Much Pool Time
Signs of enamel erosion can include:
- Tooth sensitivity
- Visible discoloration or yellowing of teeth
- A glossy/shiny appearance on the tooth surface
- Development of small dents or grooves on the teeth
- Teeth appearing more translucent, particularly at the edges
Tips for Protecting Your Teeth While Swimming
Whether you’re a casual swimmer or a competitive athlete, follow these simple tips to protect your teeth in the pool:
- Regular Dental Check-Ups: Visit your dentist regularly for check-ups and professional cleanings. If enamel erosion is occurring, your dentist can detect it early and monitor the health of your teeth.
- Rinse Before and After Swimming: Rinse your mouth with fresh water before and after swimming.
- Use a Mouthguard: Some studies suggest that a mouthguard may provide a barrier between your teeth and chlorinated water. Talk to your dentist to see if this could be a good option for you.
- Practice Good Oral Hygiene: Floss daily and brush your teeth twice a day with fluoride toothpaste.
