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.
When Should My Baby Start Walking? Most babies start to walk around 13 months, but your baby may start walking as early as 9 or 10 months or as late as 15 or 16 months. Some babies go from cruising the furniture to walking rather quickly and other babies learn to walk at a little slower pace. The pace at which babies learn to walk will vary from baby to baby.
