Tooth decay (or caries) is very common in children who have a sugary or acidic diet. Caries develop relatively fast, particularly on baby teeth, and may sometimes cause toothache. Bottle caries (putting a young child to sleep with a bottle of milk) are one of the causes of baby teeth cavities. Changing the child’s diet, avoiding bottle feeding for prolonged periods, and encouraging the child to brush his/her teeth with a pea-sized amount of fluoride toothpaste regularly is important to prevent tooth decay. The application of fissure sealants and fluoride gel by the pediatric dentist is also highly recommended to prevent tooth decay in kids.
