A SPO RTING CHANCE


Dentist Dr Julie Gallagher explains how a simple change of toothpaste could improve the performance of elite athletes


F


ROM improved handwashing techniques to bespoke pillows and mattresses, much has been written about the impact small changes had on the meteoric rise to success of the Team GB Olympic cycling team.


Now dentist and keen triathlete Dr Julie Gallagher is hoping to add one more small change to the list after her research project uncovered a surprising link between oral health in top athletes and their performance on the field. She believes a simple change in toothpaste


could provide another boost for the country’s elite sportsmen and women.


Think small It was the new head of British Cycling Sir Dave Brailsford who first brought the theory of “marginal gains” to public attention in 2002. He believed in “thinking small, not big” and adopted a philosophy of continuous improvement through the aggregation of marginal gains: focusing on such things as improved handwashing techniques to prevent illness and bespoke bedding to ensure a good night’s sleep. Within a few years his squad famously went from winning a single gold medal in its 76-year history to taking home seven out of 10 golds at the 2008 games in Beijing. Now Dr Gallagher is pushing to make


high-strength fluoride toothpaste a part of every athlete’s kit bag.


During her research, conducted as part of


her five-year, part-time PhD course at Eastman Dental Institute at UCL, the Glasgow-born clinician met with more than 350 sportsmen and women – many of them at the top of their game – across 11 different disciplines. Among the key findings was that, despite


94 per cent of athletes brushing their teeth at least twice a day, nearly half (49 per cent) had untreated tooth decay while a third (32 per cent) said that oral health had a negative impact on their training and performance. The ‘root’ cause of the problem was the


high consumption of sugary energy drinks, bars and gels. Julie says: “Athletes have a much better


general health profile so we don’t see lifestyle diseases like diabetes and obesity. “But their oral health profile is no different


to the man in the street, which is disappointing considering how closely monitored they are. “Our aim is to raise awareness of the


importance of oral health as part of athletes’ general health and wellbeing.”


Data challenge Taking on a PhD when you already have a successful dental career is a tough decision, but one that was right for Julie. In 2014, she gave up community dentistry in West Sussex to begin her research but continued to work one day a week as a tutor at Eastman Dental Hospital’s education centre.


She says: “When you do a PhD, the only


thing you know is, you know nothing so it was lovely to have one day a week when some people believed I knew something in my role as a teacher. That was a nice balance.” During the study Julie regularly braved the


busy M25 to collect data from national sports centres of excellence across the country. Team GB cyclists, runners, gymnasts and swimmers, as well as the England rugby squad, players from Reading FC and other world-class teams all agreed to an oral health check-up. While Julie measured tooth decay, gum health and acid erosion, a small team of three or four people recorded the data. For Julie, this was as much a personal as


well as a professional journey. A passionate triathlete, she has set herself the daunting challenge of competing in the 2020 Ironman race in Italy to mark her 60th birthday. She says: “I feel incredibly privileged to have had the chance to meet my heroes.” When asked who she enjoyed meeting the most, she names the GB women’s cycling team “because they do stuff I dream of”. But she is quick to emphasise it was a pleasure meeting every one of her study participants who took time out of their busy training schedules to support her work. She praises them for taking the research seriously which was vital when it came to the last part of the PhD – an intervention study. She says: “Once we had collected all the data, we
