The erosive potential of smoothies

When it comes to your diet, recommendations are continuously changing and advice is often contradictory. We all know fruit and vegetables are good for us and patients are often aware of the health benefits, particularly in relation to weight loss or living a longer healthier life. But how often do they consider the effects their ‘5 a day’ may be having on their teeth?

Dental erosion can be defined as the loss of tooth tissue by a chemical process not involving bacteria. Acids from intrinsic (such as gastric reflux) or extrinsic sources are thought to be the main causes. The loss of tooth surface as a result of erosion can lead to sensitivity or pain, poor aesthetics and pulp necrosis. Management options range from conservative preventative measures to extensive, and indeed expensive, crown and bridge work. Reported sources of external erosive acids include sports and carbonated drinks. The authors of this month's research summary question whether fruit smoothies should be added to this list.
