I would strongly suggest seeking a second opinion. (I like our ped. dentist Kurt Aarons- who is just off the Plaza in KC MO)
My oldest chipped a tooth and we were just told to watch it. Fortunately for us it only discolored and didn't abcess until she was 7 or 8 and then it was pulled.
Whatever you do, I think I would try to get your child comfortable with a dentist and dental procedures before putting her through a more traumatic procedure.
My ds just had a molar fall out - a root canal that fell out prematurely-- at age 7. A spacer was put in. Now it just keeps the teeth from shifting. And was easily placed --no painful stuff done to the surroundin teeth.
I don't know if they can just do that to a front tooth and have it look ok.
I would likely ask a dentist what ALL the options are ...
and the consequences of each.
I know I wanted dd's tooth capped for appearances and couldn't get the doc to do it(in another state). She said the caps are fragile and that the child usually just rechips/cracks the tooth during childhood before the permanent tooth comes in...so it would be a waste of money and an uncomfortable procedure for the child.
I would also be concerned if it is affecting her speech-- as learning to speak correctly when she is older may be more difficult. (My ds has speech issues - and has never had problems with his peers b/c of it...just hard to understand.)
