The King's College London team found that drinking them between meals and savouring them for too long increased the risk of tooth erosion from acid. The research, in the British Dental Journal, looked at the diets of 300 people with severe erosive tooth wear.
It said the problem was increasing as people snacked more. Fruit squashes, cordials, fruit teas, diet drinks, sugared drinks and flavoured water are all acidic and can cause wear and tear to teeth, the researchers said. And continuously sipping or holding these drinks in the mouth before swallowing increased the risk of tooth erosion.
Dr Saoirse O'Toole, the lead study author, from King's College London Dental Institute, said: "If you drink things for long periods of time, greater than five minutes, or if you play with things in your mouth or if you nibble on fruit over a few minutes rather than eating them as a whole fruit - these are things that can really damage your teeth. If you're going to have an apple as a snack at lunchtime, then try not to have anything acidic later on in the evening. If you are going to have a glass of wine in the evening, then don't have your fruit tea in the morning."
