Dental sealants are used to protect the chewing surfaces of back teeth from decay. They are acrylic-like substances which create a barrier against the bacteria which are always in the mouth and always depositing acid excretions on the teeth and gums. Sealants bond to the tooth enamel and cover all the tiny fissures and pits where bacteria would otherwise settle and thrive.
At what age do babies walk? Most babies take their first steps sometime between 9 and 12 months and are walking well by the time they're 14 or 15 months old. Don't worry if your child takes a little longer, though. Some perfectly normal children don't walk until they're 16 or 17 months old.
