Hey C.,
My oldest didn't see her first dentist until she was 3yo & that was only because she had an absessed tooth. The whole left side of her face was swollen!!! Since then, I tried a million times to get her into the dentist's, but it always ended up in a fight. The first of this month we actually got her into the chair and completely through her procedures!! (She had to be given a sedative & laughing gas for all this to be done!) She was sooooo frightened by the thought of going that she wouldn't let ANY dentist do ANYTHING! She barely let them take X-rays, she was that freaked!!!!
Anyway, when she was finished with her procedures, her pediatric dentist said that I should make an appointment for her baby sister some time soon after her first birthday. (Baby sister is now 8mo.) I think that it's only recommended at that early of an age to get them used to the dentist, the office, chair, sounds, etc.
I have some genetic dental thing that the women in my family all share. My grandmother & mother both have dentures. My sister had all her teeth pulled at age 26 and now has dentures also. I, myself, got full top & bottom dentures around that same age. My two youngest sisters haven't reached that age yet, but they are both fearing the same fate. I hope that I can get my babies to practice good dental hygiene & visit a dentist REGULARLY, so that they may avoid it also.
I encourage you to go ahead and take your darling child to visit the dentist, even if it's just to get in the chair and look around!! It will help calm any issues he/she may have later on when a visit is necessary. Visit your personal family dentist or find a pedi dentist near you.
Hope this helps & good luck!!!!!
