Hello, yes over retained milk teeth need to be removed before starting your treatment. Might also need prophylactic cleaning and fillings etc before starting orthodontic treatment.
1- Orthodontic treatment should be considered first to correct mal-aligned teeth which might take 6 month to 3years depending on the severity on an average 1.5 years. We can plan cosmetic correction for fast results but case selection is important for good result so need to see clinically.
2- Yes, braces will work for your age. Worth in terms of saving your teeth material as it is least invasive compared to other fast options.
3- oh.. Every dentist has to answer this question to most of our parents, answer is 'No'. It's a myth, we need to remove teeth manually, I have not seen any computerized or robotic tooth removal system around me, might come in future. Don't worry discuss with your dentist and go ahead with planned treatment options.
