Greg Jorgensen, DMD, Dentistry, answeredTeeth move when pressure is placed upon them. It doesn't matter if that pressure comes from metal braces, clear braces, aligners, or even fingers in the mouth. The process of moving a tooth induces inflammation around the tooth. That is what causes the discomfort associated with getting your braces "tightened." Metal braces must put preasure on your teeth if they are going to move, so YES your teeth will get a little uncomfortable. Luckily it only lasts for a day or two.

Getting metal braces, like anything new, requires an adjustment period for 5-7 days. Patients typically report mild to moderate discomfort, cheek irritation, and sensitivity to hard or chewy foods. A softer diet, over-the-counter pain medication (including Tylenol or Advil) and proper home care and toothbrushing can help reduce the amount of discomfort experienced when getting metal braces.
Years ago, before the invention of super-elastic space age memory wires, the orthodontic forces placed on teeth were much greater. Other than mild cheek irritation from the metal braces, the component of your braces that typically causes discomfort is the superelastic wire used to straighten your teeth. By avoiding the heavy forces used in the previous generation of braces, today's orthodontic patient can experience a relatively pain-free braces experience.
