Please do not worry. Extractions
are absolutely not necessary for teeth straightening
. We do a number of cases if Smile Designing or Smile Makeovers where we are able to bring about massive corrections in the smile without doing any extractions at all. Also, since she has already undergone braces treatment, it all the more does not make any sense to go for extractions now. Please let me know if you need any further clarifications or photographs of how such corrections can be achieved.
