Don't worry. My Daughter didn't get her first tooth until her 1st birthday and my son didn't get his first tooth until 15 mos...they both have very strong teeth. The longer it takes for them to come in the better off they are. My kids are 14 & 11 now and their teeth are perfectly fine. They will be late in losing their baby teeth as well just to warn you. I was the same way as a child. They didn't lose their first tooth until 1st and 2nd grades. I lost my first in first grade and my last in 9th grade. Just to give you an idea.
