Is there a link between pounds and dental health?

Is there a link between childhood obesity and dental health? University of Rochester researchers studied two separate surveys in an attempt to find out. The combined surveys polled over 17,000 youths. Researchers anticipated finding that overweight children tended to have poorer dental health because poor eating habits are a cause of both obesity and cavities. But the surveys don't support that hypothesis. Findings included:

• No dental health difference was noted in 2-5-year-olds regardless of weight range
• One of the surveys showed that 6-11-year-old children who were overweight or at risk of being overweight were actually less likely to have cavities in both baby and permanent teeth. The later survey revealed no difference in dental health when compared to weight.
  
• As in the 6-11 category, the first survey showed that 12-18-year-olds who were overweight were less likely to have dental health issues; the second survey showed no correlation between dental health and weight.
  

Rather than stating that there is no official link between pounds and dental health, researchers are stating that the results are inconclusive.
