Is It Normal for Spaces to Be Created by Braces?

YES your orthodontist could have caused spaces to appear between your teeth. NO he isn't a quack! The process of straightening your teeth takes place in stages. The first is aligning the arches. As teeth are lined up, you may notice a lot of "side effects" that make you say "hmmm?" Spaces appear where there were none before, teeth that were previously straight now overlap, or overbites are created that are worse than before the braces went on. This all occurs as the braces unravel the "compensations" that were present at the start of treatment. Your spaces, for example, were probably caused by the crowns of adjacent teeth being closer together than their roots. As the braces straighten those teeth, the crowns upright until the teeth are parellel. Although the roots may begin to move together, the crowns move apart much faster since they are in air as opposed to bone. Transitional crowding, spacing, overbites, openbites, etc. are all normal in the first part of treatment. Don't worry about them. Later in treatment however, you need to inform your orthodontist if any spaces or crowding occur that don't seem like part of the treatment plan.

Linsey, thank you for your question. During braces treatment a lot of teeth movements happen. I do not want you to worry, everything will align and spaces wil close. My advise though is to be proactive and follow up with your doctor. Afterall he is taking care of your dental needs. Bring to his attention your concerns and they will be addressed. 

Short answer: Expect a space or two to open up during treatment. AND know it is forward progress.

Long answer: When you clean out your closet you have to move some stuff out of the way to make room for the reorganizations. This is one reason for gaps to open. Another reason is as teeth are straightened they take up less room in the mouth. When the crown is properly aligned over the root of the tooth(it's healthiest and most stable position) spaces can open up on each side of the tooth, even at the end of treatment.
