Fortunately the risks are very minimal if the treatment is done correctly. However, there is always the potential for root blunting, gingival recession, decay and decalcification. Your Orthodontist is trained to properly diagnose and treat in ways that minimize most risks, but patients also have a responsibility to follow instructions especially regarding care of the appliances. Unwanted decay and decalcification are usually the result of poor dental hygiene and diet during treatment.
