Same here. I was born without my lower ones, and my upper ones came in just fine. Whenever I go to a new Dentist, the first thing they ask me is when I'm going to have them removed. I always tell them that they aren't hurting anybody, I'm keeping them clean and I like them right where they are. Its never been an issue for me.Yup, when I was 17 my dentist (15 years ago) tried to get me to make an appointment to get them removed.. I refused and said no at the time. 32 now and they all grew in fine. I understand a lot of times they grow in impacted, but it's kind of a scam.
