How Endurance Training Can Harm Your Teeth


How Endurance Training Can Harm Your Teeth

Most of us take our teeth for granted. Yet, think about how important the functions your mouth performs for you. Your mouth and teeth are the gateway for breathing, eating and drinking. The long digestive process begins in your mouth. The demands of endurance training, as well as the substances you put in your mouth, impact the healthy function of both your teeth and your entire body. Turns out that endurance athletes are particularly susceptible to dental erosion and its far-reaching effects on our bodies.

I’ve been an endurance athlete my whole life and I experienced a lot of dental problems for a period of many years. I know countless triathletes and endurance athletes who have experienced the effects of how undetected, seemingly benign oral health problems can cause a ripple effect throughout the body. These issues can  become a performance limiter by negatively impacting whole body health.

We take for granted that regular brushing alone is enough to keep us healthy. Or, perhaps it’s too expensive or inconvenient to go to the dentist regularly. However, the evidence is overwhelming that oral health is a crucial element in overall health, well-being and athletic performance at all levels.

Two Main Causes of Dental Erosion

There are two main reasons why endurance athletes are at increased risk for dental erosion: consuming sugary sports drinks and nutrition and heavy mouth breathing.

Sugary Sports Foods

Frequent small sips of sports drink or other sugars while training, spares muscle glycogen, but negatively impacts your teeth.  Sugar consumption increases acid producing bacteria that begins the cascade of potential problems.  Most sports drinks also contain phosphoric or citric acid which further erode tooth enamel. A compromised tooth is now more susceptible to bacterial build up, leading to a list of potential dental problems: plaque, cavities, gingivitis, inflammation, unresolved infection, periodontitis, etc.

However, sugary sports drinks were not the main cause of dental erosion.

Heavy Mouth Breathing

This type of breathing during endurance training leads to dry mouth that reduces saliva flow giving bacteria a bigger opportunity to grow and thrive. A 2014 study in The Scandinavian Journal of Sports Medicine looked 35 triathletes and 35 controls5, the athletes showed a significantly greater erosion of tooth enamel than controls. The triathletes had much lower levels of saliva and increased pH (more alkaline) during exercise. Saliva performs a very protective function for the teeth.  The longer the training session, the drier and more alkaline their mouths became. The more hours an athlete spent training, the greater the instances of dental erosion, tartar plaques and cavities.

The conclusion is that dry mouth combined with sugary sports nutrition exacerbates the potential harm.

Full Body Effect

If left unchecked, prolonged bacterial build up in your mouth will negatively impact how your whole body functions and performs. Advanced dental erosion has been implicated in many disease states, such as: osteoporosis, pneumonia, obesity, diabetes and heart disease. Long, hard training for days, weeks and years can leave your immune system stressed. Add to this an increased bacterial load in the mouth and your immune system struggles to keep up with demand.

Steps to Improve Your Oral Health

You can improve your oral health while continuing to enjoy and thrive with your endurance training and racing, even reverse or eliminate current problems. Here are action steps you can take:

  • Brush and floss daily
  • See your dentist for check ups 2 to 3 times each year
  • If you have any nagging tooth pain or unresolved dental problems, get this taken care of right away
  • If you need ongoing specialized care, look for a sports dentist in your area
  • Using a Sonicare toothbrush, water flosser (Water Pik) and Listerine will improve your oral health dramatically (in addition to brushing and flossing)
  • Decrease your consumption of sports drinks and other sugary sports foods. Rinse your mouth with water after consuming sugars. There is a time and place for these foods during hard training blocks and races. Work to reduce them during easy and short sessions. Instead, drink plain water or coconut water. You can also add electrolytes.
  • Work on more nasal breathing. Breathing through your nose increases the production of nitric oxide that helps to increase your lungs’ oxygen absorbing capacity and kills bacteria, viruses and other germs. This may be the hardest one to change. It takes time and focus, but can be accomplished during easier and shorter training sessions.

Be proactive about taking care of your teeth and you will improve your training, health and performance for life.

TESTIMONIALS

Mary J., Ottawa

I enjoy and respect the people that work at Centrum Dental, everyone is friendly, helpful and informative.


Vic H, Sttitsville

"I recently saw Suzie for my hygenist appointment, who I have been going to for about 10 years. She explains everything as she goes along and she is personable and friendly every time. The girls at the front desk are similarly pleasant and helpful. Dr. Khoury and his assistants have been great too, always fitting us in for any emergency or appointment change. The new office is bright and beautiful."


Helene A, Kanata

"All parties concerned are most professional and cordial. The dental craft and hygiene are super excellent in every way. The place is clean and inviting one is not afraid that they will shortcut anything to jeoparidize the person's health. Bravo to you all and thank you for the good services rendered."


Serge D., Ottawa

"As usual, the staff is very welcoming as soon as you open the door. Suzie is a great hygienist."


Maureen O., Kanata

As always, it was a positive experience. Having done more of the suggestions I was given from the last cleaning, my gums were better. Just goes to show that one must do what one is advised to do by the professionals, and they are just that at the Centrum Dental Centre. Its always a pleasure dealing with them, and I always come away smiling, which is a good thing coming from the dentist! Keep up the good work!


Christine H., Kanata

"I highly recommend the Centrum Dental centre. For such a skitish patient they always take such good, good care of me. Dr Ghamian is incredible and has always been kind and patient. Perhaps that is why I have referred many of my clients to them year after year."


Ahmed E.

"I almost fell asleep while getting my root canal! The pain was gone in less than a day... and I was able to eat on that side in 2 days! Thank you Dr. Khoury! You're a magician :) Very pleasant staff and experience!"


Dale M., Kanata

"Kim V. was thorough and always helpful in her suggestions/tips. Her highly personable style makes the visit that much more enjoyable. Dr. Ghamien tends to make each patient feel welcome and "not just another appt" regardless of nature or length of visit."


Marc A.

“I highly recommend Centrum Dental. The staff is consistently polite, friendly, professional and available. I have had several procedures done, from fillings to root canals and extractions, and the work is always to my satisfaction. Dr. Khoury is punctual, painless, and always explains procedures. I am entirely satisfied with my experience at Centrum Dental.”


Cade B., Kanata

"Very good experience. This was Cade's first filling without any gas and he did great. Dr. K was so good with him"
