Our lg is 19 months and her top two front teeth and perfectly straight but the two either side of those are set slightly further back, making it look like her teeth are wonkey. She does have a dummy but only has it through the night, although not all night as she will fall asleep without it and it often falls out her cot in the night and she doesn't notice. She also never had a dummy until she was in hospital at 12 months so not long. Could it still be causing it or do toddler teeth often line up one the rest come through?
