Traditional braces would not be deemed comfortable by anyone. Beyond the poking from stray wires and the rubbing of lips, cheeks, and tongue, there are also the “tightening” sessions when the wires are tightened and new rubber bands applied. These can require over-the-counter pain medication for a couple of days afterward.
In contrast, the SureSmile aligners are comfortable on your teeth — no wires or bands. There are no “tightening” sessions; you simply replace the two aligners every two weeks with the next pair in the series. When the new aligners are put in, the initial adjustment is nowhere near the same as a tightening session with traditional braces.
