In a study done in the United States and published in the Journal of Public Health Dentistry, it has been found that for people who consume sugary soft drinks and fruit juices, a large number show signs of dental erosion. Surprisingly the worst tooth wear was an outcome of Fruit drinks consumption, while milk tended to be a more common beverage for people with lower levels of tooth wear.
The conclusion is that, water and milk are the best beverages to consume in order to avoid tooth wear and erosion since they lack sugar, whilst beverages like soda and fruit juices which contain sugar should be consumed in moderation.
