You've received a lot of advice and just wanted to share my experience. (From what I recall, without getting out the baby books.) Both of my kids, now 6 and 9 were "late" in getting their teeth. My 9 year old daughter even more so...her first tooth "emerged" a week before she turned one. And the rest were very slow at coming in as well.
But, like you said...they are generally healthier. My 6 yr. son has yet to loose a tooth and my daughter did not loose hers until the end of 2nd grade, now going into 4th grade, has only lost 6. Not to do the comparison thing, but she has very healthy teeth (no cavities), compared to some of her friends who got their teeth early and have lost them and have had multiple cavities.
As hard as it may be on you right now, be ready for your child to be upset about it later. It was upsetting to my kids, especially in Kindergarten when many teachers have "charts" of who has lost a tooth, when they don't lose theirs. So, figure out your "comeback" to those who are comparing now and be ready to explain to your children. I used the opportunity to talk about their "baby years" ...they love hearing stories about themselves. I explained that everyone gets their teeth at different times and your first one didn't "pop out" until a week before your first birthday and showed her pictures. Then, explained that the dentist said it's actually healthier to keep their baby teeth longer too. Anyway, it seemed to help my kids.
Just keep very positive and matter of fact in your replies and don't let it get to you, knowing it's actually a good thing! Good luck.
