Developed by passionate cyclists – the science behind base
base products are designed to be used during exercise in parallel with existing, high sugar/carbohydrate sports nutrition, allowing users to maintain high levels of performance. Fuel your workout, protect your teeth (and read the science).
The science shows consumption of glucose, fructose and sucrose found ubiquitously in sports nutrition products can lead to an increase in dental cavities and a decline in oral health (1). Primarily, the acid produced during bacterial fermentation of supplied sugars softens and de-mineralises dental enamel (2), whilst the low pH of sports drinks can also directly degrade enamel, promoting calcium and phosphate stripping, leading to tooth decay (3).
Some sports (especially cycling) may have durations of >2h, where consumption of high sugar products is constant, to maintain performance (4). Although saliva acts to re-mineralise enamel by neutralising acids, this can take over an hour depending on the quality of the saliva and whether the athlete is dehydrated (athletes are often chronically dehydrated; 5, 6). In order to allow saliva to re-mineralise enamel, consumption of sports nutrition products must cease: this is often not desirable during training and competition if performance is to be maintained (4). Should dehydration occur, the body preserves moisture by reducing saliva flow, exacerbating dental erosion (6).
Over such timescales as typically seen in endurance sports (>30 min), significant decrease in oral pH (7) and damage to dental enamel has been reported (8). The link between sports drink (and other high sugar products) consumption and dental health has been made in many studies and is conclusive, showing that increased consumption is detrimental to dental health (1,2,3,7,8).
During a period of endurance exercise, few opportunities exist for participants to care for their dental health by neutralising oral acids and removing bacterial biofilms. Intra-workout brushing is not an option, use of a mouthwash would taint any subsequent food/drink consumption, whilst water is often not an attractive, nor an effective option (owing to the low contact time between water and teeth).
