Sour, sweet, nasty
Sweetened drinks as a factor of obesity and tooth wear
A new study published in the journal Clinical Oral Investigations (Kamal et al., Obesity and tooth wear among American adults: the role of sugar-sweetened acidic drinks) has shown that sugar-sweetened acidic soft drinks are a common factor in obesity and tooth wear in adults, according to a press release Soft drinks found to be the crucial link between obesity and tooth wear.
Scientists from King's College London found that being overweight or obese was undoubtedly associated with tooth wear. Notably, they also found that increased consumption of sugary soft drinks may be the main cause of tooth enamel and dentin erosion in obese patients.
Based on data from the National Health and Nutrition Examination Survey conducted in 2003-2004, the researchers analyzed a representative sample of survey participants from 3,541 patients in the United States. The patient's BMI and the level of tooth wear were a measurement of exposure and results in the analysis. Consumption of sweetened sour drinks with sugar was recorded in two inconsistent 24-hour surveys, during which patients were asked to provide information about their diet during these two days.
"It is the acidic nature of certain beverages, such as carbonated drinks and sour fruit juices, that leads to tooth wear," says lead author Dr. Saoirse O'Toole of King's College London.
Tooth wear is considered the third most important dental condition, after caries and gum disease, and the consumption of acidic food and drinks is the main reason for this. Obese patients also have other risk factors, such as an increased likelihood of gastric reflux disease (heartburn), which was controlled in this study.
"This is an important message for obese patients who consume calories from sour drinks sweetened with sugar. These drinks can harm their body and teeth. There is also an important message for dentists. We need to ask our patients who are obese and have tooth wear about what drinks they drink, because it can affect their body as a whole, and not just their teeth," added Dr. O'Toole.
Previous studies by King's have shown that tooth wear affects up to 30% of adult Europeans. This is premature tooth wear due to softening of the tooth enamel from food or stomach acids in combination with wear. This happens when the outer layer (enamel) of the tooth slowly dissolves. This can lead to a change in the shape or appearance of the teeth, and they can become sensitive to cold food and drinks. In the worst case, the tooth structure may gradually wear off. Severe erosive tooth wear reduces the quality of life and can mean the need for complex and expensive procedures, costing up to 30,000 pounds per patient. Tooth wear can be prevented by changing eating habits.
