According to a large European study, mothers of three children would have on average four teeth less than mothers with two children.
Having a large family would be linked to tooth loss according to a large European study published in the Journal of Epidemiology and Community Health. To reach this conclusion, researchers at Radboud University in the Netherlands used data from the SHARE Survey of Health, Aging and Retirement in Europe. This European survey contains information on the health, education and household income of more than 120,000 adults aged 50 and over from 27 European countries and Israel.
On average, adults have 28 teeth plus 4 wisdom teeth. But adults in the SHARE study reported an average of ten fewer teeth, ranging from nearly 7 fewer teeth for women aged 50 to 60 to 19 fewer teeth for men 80 years and older. By pushing the statistics further, they found that mothers of three children averaged four fewer teeth than mothers of two children.
“This study provides new evidence of the causal relationship between the number of children and the number of missing teeth. An additional birth may be detrimental to the mother’s oral health but not to that of the father,” say the researchers who recommend that special attention should be paid to oral health and the feeding of future mothers.
