I would definitely start taking her to the dentist now, while its not scary. Pick a children's dentist, they are great with small children. She can get used to it when there's not a lot to do, and they can also evaluate her bite. Sometimes it will self-correct, and sometimes not, particularly when there is a crossbite, like my 5 year old son has. He's been going to the dentist since age 1, and is very comfy with them now. Don't worry...there's plenty of time to correct her bite if necessary!
