Is it normal for a baby to have no teeth at 6 months?

Yes: Although on average babies will erupt their first tooth between 5 to 7 months of age, there is a wide range of normal. Some babies will sprout that first tooth at 4 months old, while others won't be flashing those pearly whites until they reach one year old. Typically, the bottom central teeth are the first to erupt. Not to worry, i'm sure your baby's first tooth will soon make its debut!

Yes: There is tremendous variation in tooth eruption in normal infants. In three decades I have seen a handful with natal (at birth) teeth which can be loose or firmly attached. I have had as many with no teeth until 15-16 mo. We expect 1/mo starting at 4-5 mo as average with 20 by 3y. Delayed eruption does not mean a dietary or growth problem but may be rewarded by less cavities over time.

Yes: Some children are dentally delayed.

Late side but OK: While most infants get their first teeth between 4-6 months, there is a lot of normal variability. As long as they are healthy otherwise, i wouldn;t worry about late teething. Children who get their baby teeth later also tend to get their permanent teeth later as well.

Tooth Eruption- Norm: Average age of first tooth eruption is 7 months, but it may be early or late. First comes 2 lower central incisors at 6 1/2 mo, then 2 lateral incisors 7 mo, then upper 2 central incisors 7 1/2 mo, then upper 2 lateral incisors 8 mo. Premolars- 12-16 mo. And so on. Ref: nelson textbook of pediatrics. There can be overlap.

Not unusual: 6 months is an average. Some babies born with tooth/teeth present, some don't begin to teeth until a year and a half. If concerned, see a Pediatric Dental Specialist. Whether teeth are present or not, ALL children should have 1st Oral Cavity Examination no later than 1st b'day. Recommend seeing a Pedodontist.
