"A mouthful of water following a mouthful of sports drink (also called a “water chaser”) does not prevent dental erosion."
"Use neutralising products, fluoride varnishes, gels or rinses, remineralising agents such as CPP-ACP added to chewing gum, lozenges, mouthwashes or milk to re-harden tooth surfaces. Fluoride, bicarbonate and calcium can also be added to sports/soft drinks to reduce their erosive potential but may also affect the taste and palatability."
