Does Pulling out Good Teeth when Getting Braces Have Disadvantages in the Future?

Sometimes there just isn't any way around it, but most of the time permanent teeth don't need to be pulled.  It may take longer for treatment, but the end result is better.  Disadvantages to pulling teeth is that airways can be affected and facial aesthetics are altered.  TMJ issues are debatable, but there is strong opinions that pulling teeth leads to TMJ problems as an adult.

Hello and thank you for your question.
Sometimes there is  no choice but to remove 2 teeth on the top due to limited space.
In most cases though you have 2 choices. Either to remove teeth to gain space OR move the upper teeth back. I prefer a second option. It obviously avoids pulling teeth and discomfort associated with it. Treatment might take longer, but long term results are better.

To answer your question directly, yes, there can be future negative consequences of having permanent teeth removed.  Traditional orthodontists believe that bicuspid extraction approach is best when teeth are crowded, however there can a better way to treat teeth like you have.  The problem typically is not that a person with crowding has too many teeth, or that the teeth are too big.  The problem is that they have narrow (underdeveloped) jaw structures.  If they are left narrow and underdeveloped, then teeth extractions become necessary in order to straighten the teeth.   By correcting the facial structures with special orthopedic expanders, the narrowness of the jaws can be corrected gaining space for all the teeth, thus eliminating the need for the teeth extractions.  With this approach the patient also end up with a much more full smile.  Other benefits like better breathing through the nose, healthier jaw joints (TMJ) and even better spinal alignment are possible with this approach as well.
