People who do not drink tap water likely to have tooth decay
CChildren and adolescents who do not drink fluoridated tap water are much more likely to have tooth decay, says a US study. However, the study added that those who drink tap water are more likely to have elevated levels of lead in their blood.
Researchers from the University of North Carolina (UNC) said that people who did not drink tap water were more likely to have tooth decay than tap water drinkers. But they were less likely to have elevated blood lead levels. The researchers said this in the study published in the journal Preventive Medicine.
Overall, nearly 3% of children and adolescents had elevated blood lead levels and 49.8% had tooth decay.
“Elevated blood lead levels affect only a small minority of children, but the health consequences are profound and permanent,” said Anne E Sanders, from the UNC.
“On the other hand, tooth decay affects one in every two children. Its consequences, such as toothache, are immediate and costly to treat,” Sanders added.
