Most people experience tooth soreness for a few days after starting each new stage. This is normal. It is a sign that the Invisalign aligners are working, moving your teeth to their final destination. This soreness should gradually go away a couple of days after inserting the new aligner in the series. If it doesn’t, promptly call your dental practitioner.

Like all orthodontic treatments, the aligners may temporarily affect your speech and you may have a slight lisp for a day or two. However, as your tongue gets used to having aligners in your mouth, any lisp or minor speech impediment caused by your aligners should disappear.

Minor discrepancies between the new aligner and the current tooth position are normal, since the teeth need time to conform to the new aligner position. In the event of significant problems with aligner fit, inform your dental practitioner.

In general, no. Unlike traditional orthodontics, you can usually eat and drink whatever you desire because you remove your aligners while eating. Thus, there is no need to restrict your consumption of any of your favourite foods and snacks, unless otherwise instructed by your dental practitioner.
