Babies dont need braces and just because they may be a little crooked now, doesnt mean they will be when her adult teeth come in. A lot of times, jaw space has a lot to do with how the teeth come in, so if your daughter has a small jaw, then talk to a dentist as her adult teeth come in to ensure that you are doing what is right. My son wears a retainer now at the age of 8 and has for a year and a half as well as a spacer to help retain his space so his teeth will grow in straighter.

Talk to your pediatric dentist and get their opinion.
