Whats wrong with taking out teeth?
It is stressful to the patient and in the vast majority of cases a non-extraction approach will work just as well or better and is a more holistic solution. Up to 80% of crowded cases have an element of jaw size discrepancy (ie small jaws instead of big teeth) so it makes sense to correct this by making more bone before resorting to removing healthy teeth. In addition the process of having four extractions can never be made a pleasant one.
