Research shows a direct link between oral health and sports performance. Thus, Annimari Korte, a Finnish endurance runner, finds it disappointing that sports bodies such as her home country’s Olympic Committee do not support the oral health of competitive athletes like they support general health by paying for medical and physiotherapy services. Even though good oral health is known to improve sports performance and results.

Annimari said, “Throughout the years I have represented Finland as a competitive athlete, there has been no official talk about the importance of oral health in top performances.”

Annimari believes insufficient information is the most significant reason official sporting organisations do not support their athletes' oral health more visibly.

Annimari added, “I hope this situation will change. Studies have shown that oral problems such as gingivitis and periodontitis have been shown to reduce performance significantly.”

Top sport is a risk factor for oral health

Research indicates that elite sport is one of the most significant risk factors for the onset of oral diseases. According to one study, caries is found in up to 70 per cent of competitive athletes, dental erosion in almost 40 per cent and severe gum disease, periodontitis, in up to 15 per cent of top athletes.

Furthermore, studies show that the oral health of athletes appears to be poor in a wide range of sports. Various underlying medical conditions can hamper training results and impair sporting performance; oral infectious disease is no exception.

Concerns about the oral health of athletes are nothing new. For example, during the 2004 Athens Olympics, the second most requested health service for athletes after physiotherapy services was dental care. Meanwhile, at the 2012 London Olympics, it was noted that Olympic athletes had poor oral health. Up to 55 per cent of athletes had high caries levels, 76 per cent had gingivitis, and 14 per cent had periodontal disease.

One study examined the oral health of top Dutch athletes before the Rio 2016 Olympics. This study found that almost 50 per cent of top athletes needed regular dental care and suggested that oral health screening, included in the overall preventive healthcare of elite athletes, is essential to ensure that athletes are fully healthy during competitions such as the Olympic and Paralympic Games.

Dental Research notes that oral health is not part of most sport and exercise or nutrition curricula or integrated within athlete health strategies. Consequently, the importance of good oral health is not fully understood despite the clear link between good oral health and athlete performance.

Inflammatory oral diseases such as gingivitis and periodontitis are common in top athletes. Oral diseases such as gingivitis and periodontitis have been reported to harm the performance of athletes. One reason is the pain and discomfort associated with oral diseases, making concentrating difficult and hampering training results. Links have been reported between muscle injuries and poor oral health in athletes.

There are many possible reasons for the high prevalence of inflammatory oral diseases in competitive athletes. Physical strain is one of the most important. Heavy training increases the body's stress levels, which directly affect oral health and susceptibility to the onset of various gum diseases. Physical exertion affects the composition of saliva during exercise and reduces its secretion. Frequent oral breathing during exercise and dehydration further contribute to dry mouth. All these factors predispose to tooth decay and enamel erosion and contribute to the onset of inflammatory oral diseases.

Saliva secretion has a variety of effects on dental health. Saliva prevents decay by restoring the pH of the oral cavity from acidic to neutral after eating and by helping to restore minerals dissolved by acids to the tooth surface. Saliva also removes two to four grams of microbes daily from the mouth and tooth surface to the digestive tract.

Dietary choices also have a significant impact on the oral health of athletes. Rigorous training programmes require regular eating, supplemented by 'sports nutrition' such as carbohydrate gels and bars consumed during training. This strains oral health by increasing the number of daily acid attacks in the mouth.

A healthy mouth is an integral part of overall well-being

Annimari Korte held the Finnish record in the 100-meter hurdles from 2019 to 2023. She has also represented Finland several times in world championships. However, she has not had an easy career, as a bout of illness forced her to take a five-year break from competition in 2012. However, the health challenges taught Annimari the importance of overall well-being, including good oral health.

According to Annimari, the Finnish Olympic Committee covers as part of its comprehensive health package visits to a doctor and physiotherapist, but not, for example, visits to a dentist or oral hygienist.

Annimari said, “Regular oral health professional visits would help detect oral health problems early. For example, severe and often asymptomatic periodontitis can be very detrimental to an athlete's overall health and well-being.

“At least primary dental care should be covered for competitive athletes, as it affects their overall health and sporting performance.”

Juuso Simpanen, a trail runner turned professional, Annimari's views on the importance of oral health for athletes aiming for the top.

Juuso said, “Only a fully healthy athlete can achieve top results. If your mouth is not in good shape, it will also hurt your results.”

As an endurance athlete, Juuso says he eats very often to meet the high-energy demands of training.

Juuso commented, “Consuming high amounts of energy exposes my teeth to constant acid attacks. That's why I pay special attention to my oral health. I brush my teeth morning and evening, floss and use antibacterial photodynamic Lumoral-treatment regularly.”

In Juuso 's opinion, support for professional athletes to maintain their oral health would be very welcome. He added, “At least annual dental check-ups at the dentist would be worthwhile, and why not guide athletes in using new, scientifically proven, effective dental methods? This would prevent many infections in the mouths of top athletes. This would also reduce inflammation, injuries and illnesses in athletes.”

Gingivitis is a severe inflammatory disease

Athletes must get their bodies in the best possible condition to reach the top. Extensive research shows that dental and oral bacteria are linked to many chronic diseases of the body. In addition to heart disease, oral diseases are linked to lung disease, diabetes and metabolic problems in healthy people.

Periodontal disease is a long-standing inflammation of the gums. Over time, the inflammation damages the attachment tissue of the teeth, causing the collagen fibres that hold the teeth to the jawbone to break and, in the worst case, lead to tooth loss. Early signs of periodontal disease include reddened and swollen gums, bleeding of gums and bad breath.

Inflammation of the gums causes low-grade inflammation in the body, which is linked to vascular health and the performance of athletes. Oral bacteria lingering on tooth surfaces and gum pockets are spread throughout the body when teeth are brushed, and food is chewed. Even asymptomatic oral conditions can affect the health of the whole body.

Tommi Pätilä, a specialist in cardiac and organ transplant surgery at HUS New Children's Hospital and one of the developers of the antibacterial Lumoral method, said, “Statistics show that people with a healthy mouth live longer. Each missing tooth reduces life expectancy. This is far too little talked about.”

According to Tommi, it is estimated that up to two out of three people over the age of 30 suffer from periodontitis. This common gum disease can lead to tooth loss if left untreated - but it is also linked to severe heart events. According to a study, a first heart attack is 30 per cent more common in people with periodontal disease than in healthy people of the same age.

Effective oral hygiene prevents oral disease

According to Juuso, there is minimal discussion among athletes and sports managers about the risk factors for oral health in elite sports. However, there is good reason to do so.

Juuso admits, “During long training sessions and intense competitions, drinking sports drinks and eating energy gels puts teeth and gums under strain. Scientific studies also show this.”

At his worst, Juuso says that in a 20-hour race, he eats or drinks something sugary every 15-20 minutes throughout the race.

Juuso said, “In addition, almost every week, I do one long training session of four to eight hours, where I also practice taking energy and sports drinks like in the race.”

Juuso says he takes oral health seriously. He takes care of his teeth by brushing twice daily and regularly cleaning his interdental spaces as recommended by specialists. For the last eight months, he has also regularly used a new oral care device based on antibacterial photodynamic therapy.

By using the Lumoral method, Juuso can be sure that his oral health remains optimal despite strenuous competitions and training sessions.

Juuso explained, “I brush my teeth thoroughly in the evening for up to 10 minutes before going to bed. I use Lumoral two to four times a week before brushing my teeth.

“It is especially important for an endurance athlete to take care of their oral health outside of training and competition, as they consume a lot of sports drinks and energy gels in competitive situations and during long training sessions.”

The Lumoral treatment, developed by Finnish researchers, improves dental self-care and oral health even when traditional methods are not sufficient. The Lumoral treatment can remove 99.99 per cent of plaque bacteria from the surface of the teeth. Lumoral is a targeted treatment, which means that the normal and important bacterial flora in the mouth is preserved. At the same time, gum inflammation is controlled.
