My 7 month old doesn't have teeth yet is that normal?

Yes: Infants can have their first teeth present at birth or as late as 15 months. The later erupting group often get several erupting at one time.It is not an indicator of growth or nutrition problems but a variation of normal. Most have a full set of baby teeth by 3y.

No, but don't worry.: Eruption of permanent teeth usually begins at the age of 6 (but that is the average). 7 is a good time to visit an orthodontist, or have your general dentist take an x-ray known as a pan.

Yes: The eruption of primary (baby) teeth does not not follow a rigid schedule. The first teeth usually arrive at 6 months of age, but there is a range. Some infants are actually born with with teeth, others have their first teeth erupt later than 6 months. Don't worry.
