Can braces cause an overbite?

I am a 28 year old female. I want to know if braces can cause an overbite?

It fixes overbites.
Not the brace by itself, but instead forces applied in the wrong direction can deepen the bite.
You should check with your orthodontist to evaluate what the plan is to fix that. Sometimes it is necessary to make an overbite to fix other things. There is a process and it can be confusing. We always plan BIG picture, and the small details are the bite does change.
With an improper treatment plan excessive overbite can be caused by braces, If there is not enough overbite to begin with, it is possible to create a normal overbite as well.
Braces can certainly cause teeth to move.

You are wise to ask this question. We do not want to cause, or increase, an overbite.

We want to reduce or eliminate an overbite. Ideally, we want the biting edge of the lower front teeth to be just barely behind and above the biting edge of the upper front teeth.

In many cases the best way to reduce an overbite is to support the lower jaw more down and forward, not just by moving the teeth. This will move the tongue down and forward as well, creating more room for it. Increased tongue room will reduce the risk of snoring and sleep apnea. The teeth are then moved to fit to this improved jaw position.

For the very best information available on this subject, read the chapter on orthodontic treatment in the book:
It is available on line. This would be very important for you to read. After reading the chapter several times, you will be in an excellent position to have a meaningful conversation with your orthodontist.
Assuming that you are being treated by a competent orthodontist, braces will cure your overbite and provide you with normal occlusion.
They can correct it or cause it. 


This is a very interesting question but it has a pretty complicated answer. Braces do not usually an overbite; but it is helpful to have a good understanding of some of the terms involved. Overbite refers to the amount teeth (usually front teeth) overlap from top to bottom. Another way of looking at this is how close due the upper front teeth get to the lower front gums. Overjet refers to how far front teeth overlap horizontally. Another way of thinking about overjet is, are the upper front teeth closer to the tip of the nose or the lower front teeth.
If there is crowding, this means that there is not enough room for the teeth to stand next to each other so they start rotating and slipping behind each other. In order to fix this the teeth have to be moved to the front of the patients face. Usually what happens is that the braces bring the teeth forward, then straighten them (once forward there is enough room to rotate them) then push them back while they are straight (inter proximal reduction, IPR, can be done at this stage to push them back a little further. Smile-direct club may have some convenience advantages; however, this is where some of its flaws are in treatment. The problem for the patient is that if the lower teeth are not crowded, but the upper teeth are. This means the upper teeth have to get moved forward by the braces but the lower teeth do not. This is increase the overjet, but the not normally the overbite. Overbite is largely dictated by the back teeth.
Hope this helps.

My best to you!
