On December 13th, Vilanova i la Geltrú hosts one of the most anticipated sporting events of the year: the Vilanova Half Marathon. An event that brings together hundreds of runners from all over, a passion for sport... and which, surprisingly, has a lot to do with the health of your teeth.
Yes, you read that right. Running can affect your oral health. And if you are one of the many runners who train or compete in the capital of Garraf, this article will interest you.
Why do athletes also need to go to the dentist?
Regular runners, especially those preparing for half marathons or full marathons, may experience alterations in the mouth that, if not controlled, can lead to problems:
- Persistent dry mouth
- Increased cavities
- Tooth enamel wear
- Gum problems
- Tooth sensitivity
All of this may seem secondary, but if you train intensely and don't monitor it, you can end up seeing how your smile suffers... and also your performance.
Common dental problems among runners
1. Dry mouth due to mouth breathing and dehydration
When you run for long periods, you often breathe through your mouth, which reduces saliva production. The result? A feeling of dryness, but also an increase in bacteria and the risk of cavities and halitosis.
2. Gels and energy drinks: hidden sugar
Many athletes use gels, bars or isotonic drinks to maintain energy. The problem is that they are often very acidic or rich in sugars, which promotes dental erosion and the formation of cavities, especially if they are taken repeatedly and without subsequent hygiene.
3. Bruxism and muscle tension
Bruxism (involuntary clenching of the teeth, often at night) is also common among runners who train very intensely or live with competitive stress. Furthermore, in demanding races such as the Half Marathon, unconscious jaw tension can be generated.
4. Dental wear due to acids and pressure
Athletes who regularly consume supplements, citrus fruits or acidic drinks can suffer progressive wear of tooth enamel. The combination with bruxism makes teeth suffer doubly.
How to protect your mouth if you run the Vilanova Half Marathon?
1. Hydrate well before, during and after
Water doesn't just help your body: it also helps your mouth. Good hydration prevents dry mouth and helps reduce the accumulation of bacteria. Avoid sodas or highly sugary isotonic drinks outside of the race.
2. Brush your teeth after taking gels
We know that during the race it's complicated, but if you can rinse well with water after an energy gel or drink, even better. And at home, after the race, brush immediately.
3. Visit the dentist before and after the event
A pre-race check-up can detect sensitivities, incipient cavities, or problems that can get worse with exertion. After the half, it's worth checking to make sure the intensity hasn't taken its toll.
4. Use fluoride toothpaste and a soft brush
Protect the enamel with a good toothpaste and avoid hard brushes that can aggravate sensitivity if there is wear. You can also consider using remineralizing mouthwashes.
5. Treat bruxism with a relief splint
If you have jaw discomfort or notice that you are clenching your teeth, it is important to take action. At Clínica Albiol we can make you a custom splint to reduce wear and tear and avoid muscle tension.
