The Obesity–Cavity Correlation

The Obesity–Cavity Correlation

One has been called a public health crisis; the other is the most common chronic infectious disease occurring in children. But both can affect a child’s growth, health and self-esteem. We’re talking about obesity and dental caries (cavities). The two are not only growing health concerns but may be related.

Within the past decade, several studies have shown a possible correlation between obesity and dental decay in children. Experts aren’t sure why or how―or even if―the two conditions are related. One study by researchers from Case Western Reserve University in Ohio found that as body mass index went up, so did the risk of cavities. Another study, published by the National Institutes of Health, suggested that childhood obesity may cause premature permanent tooth development, which can lead to decay and jaw problems. These findings are concerning, especially because the Centers for Disease Control and Prevention warns that one in seven low-income preschoolers is obese and at risk for dental caries or periodontitis.

The long-term health effects of childhood obesity are well known, but many parents might not be as familiar with the problems caused by dental caries. Severe caries can have an impact on a child’s speech and language development, as well as sleep, learning and eating habits. The good news is that the same dietary changes can help reduce your child’s risk of both conditions. A healthy diet, emphasizing fresh foods (fruits, vegetables, proteins and complex carbohydrates) over processed foods and a reduced sugar intake (especially from sugary sodas and candy), can be a great start.


We may not be sure why children who are overweight tend to get more cavities, but we can make a healthier lifestyle a priority. If you’re not sure where to start, ask us for nutrition recommendations that can benefit your children’s teeth—and their waistlines!
