My 12 YO daughter, also suffers from OCD, ADD and tactile sensory disorder ( doesn't like how things feel. ie, clothing, shoes, sweaters), let alone having a spacer for 6 months in her mouth and braces for 2 years. I need advice. I thought a spacer alone would work, that's what the dentist thought. But ortho said 6 months spacer and then 2 years braces. My fear ( and daughters too) is what if she can't handle the feeling of the spacer? She can't handle many feelings, how things feel, etc. What are the worst case if we do nothing? she has all her baby teeth gone, one more canine to still come down. Ortho said the space is small for it and spacer could help, but then said spacer could make teeth move and then need for the braces. How bad of a crossbite is needed to have it fixed? Thanks for help. Any advice, alternatives? pros and cons?
