What happens .........
The outer enamel tooth surface is susceptible to acidity which can result in dental decay , dental erosion or both. Enamel and dentine are dissolved at pH less than 5.5 . Sports drinks have
pH 2.4 - 4.5. Salivary flow neutralises acids and tooth remineralisation occurs. However prolonged exposure when sipping sports drinks lengthens the recovery phase so teeth are more vulnerable to erosion. The form of sugar in energy drinks and gels is a type that adheres to teeth more than saliva and provides a substrate for additional acid production by bacteria.
Dehydration is an issue for many athletes ....a dry mouth decreases salivary flow and increases the time for tooth surface damage.
Common mouth myths .......
Water chaser - Rinsing with water will not prevent erosion? It doesn't contain bicarbonate calcium or phosphate.
Brushing makes it OK? Actually, brushing within 30 minutes of consuming sports drinks or gels can cause further damage as the tooth surface is still soft
How to minimise Dental Erosion ........
* For children and low intensity sports tap water is appropriate
* Dental products such as tooth mousse can help protect teeth
* A water chaser can help by clearing the acidic beverage from the mouth and rehydration will aid salivary flow
* Use neutralising products ...varnishes gels rinses , milk , CPP-ACP in chewing gum (Orbit ) to remineralise tooth surface
* Swallow drinks immediately or take with a straw (Camelback ....) . Do not hold or swish
* Do not rinse your mouth with sports drink before inserting mouth guard
* Avoid dehydration and rehydrate quickly during recovery
* Delay brushing teeth for at least 30 minutes after consuming sports drinks
* Discuss your training and hydration regime with your dental professional
* Have regular dental check ups to detect early damage
Happy training ...and keep smiling !
