Delayed Teething in Infants
Remember, however, that every child develops at his or her own pace. If your child's first tooth has not erupted by her first birthday, do not be alarmed, but do consult her pediatrician for next steps. And if you're concerned about your baby being able to move on to finger foods in a few months (at approximately nine to ten months of age), there's no need to worry. Babies use their gums and tongue to mash lumps of food, so it doesn't matter if your baby has no teeth.
Also remember once your child's teeth do arrive that it's never to early to start taking care of her teeth. You should begin a daily dental cleaning as soon that first tooth appears by simply wiping the teeth and gums gently with a damp cloth. The American Academy of Pediatrics also recommends that all infants receive an oral-health risk assessment by six months of age. Consult your baby's pediatrician about when she should have her first visit to the dentist.
