Moving More, Smiling More

In September, we celebrate National Fitness Day. It is a great reminder that physical activity isn’t just about how we look or how fit we feel, it impacts our overall health, including our oral health. When we exercise, swim, play sports or simply get active, many positives flow through the body and the mouth is no exception.

Sport, Swimming and Oral Health

Swimming

Frequent exposure of teeth to chlorinated water can lead to staining, tarter build-up and enamel erosion. For more information, read our swimmers mouth article.

Sports & Energy Drinks

High in sugar and acid, these drinks can cause enamel erosion and cavities. Click here to read more.

Oral Health & Performance

Gum disease, tooth decay or infections can impair sleep, nutrition and training quality. Click here to read the impact of sports on oral health.

Supplements, Gels & Powders – Hidden Sugar Risks

While swimming pools and sports drinks are obvious oral health factors, the fitness supplement world also brings hidden risks.

Running gels and chews

Many endurance athletes use energy gels that are high in glucose, fructose, or maltodextrin for quick energy. These sticky, sugary substances cling to teeth and fuel bacteria, increasing cavity risk.

Pre-workout powders

Some contain added sugars (or sweeteners plus acidic flavourings), which can lower the pH in the mouth and soften enamel. When sipped slowly before exercise, they prolong acid exposure.

Protein powders & shakes

Not all are sugar-free. Some blends, especially mass-gainers or flavoured options, can contain significant sugar content. If consumed late at night after a workout, the risk is higher if brushing is skipped.

Reduce Impact

1. Rinse with water immediately after gels, powders or shakes.
2. Avoid holding the drink in your mouth; sip and swallow.
3. Check labels and choose low-sugar or sugar-free options.
4. Brush teeth with a smear of fluoride toothpaste after workouts (but wait 30 mins if you’ve had acidic supplements to protect enamel).

Why Oral Health Matters for Fitness

1. Nutrition, hydration, and mouth health go hand in hand. Water supports saliva, which neutralises acids and protects teeth.
2. Mouth pain = performance limiter. Tooth sensitivity, decay or infection can affect sleep, energy and focus.
3. Injury prevention matters. Mouthguards protect against chipped or broken teeth in contact sports.

Tips for Celebrating the Healthy-Smile Way

1. Choose water before, during and after exercise.
2. Protect your teeth with a mouthguard for contact sports.
3. Rinse after the pool to counteract chlorine exposure.
4. Check your supplements for hidden sugars.
5. Stay hydrated to support saliva and tooth protection.
6. Book regular dental check-ups to prevent problems.
