Washington, Feb 23 - A new study has revealed that tooth decay is not only the most common chronic childhood disease, but is infectious too.

According to the study by researchers at University of Louisville School of Dentistry, mothers with cavities can transmit caries-producing oral bacteria to their babies when they clean pacifiers by sticking them in their own mouths or by sharing spoons.

According to Liliana Rozo, tooth decay can have a detrimental effect on a child's quality of life, performance in school and success in life.

The disease can cause pain, inability to chew food well, embarrassment about discolored or damaged teeth, and distraction from play and learning. (ANI)
