Q. Dr Moore, My 7 year old daughter has a very severe underbite – can you please advise what’s the best course of action for us to take. We consulted a dentist previously who advised that nothing can be done until she has her adult teeth. What kind of treatment can we expect then to remedy the problem., and how successful will it be? Should we seek the advise of a specialist orthodontist now? I would be very grateful for any advice.,
