Wearing braces and aligners is simple and generally quite easy with the modern devices available. However, both need to be regularly adjusted, and this may make the teeth feel tender for a day or two. The fitting of braces and Invisalign is generally painless. Tenderness usually occurs several hours after placement of the appliances and similarly after adjustments. Most of our patients require some mild analgesic after the initial fitting and won’t use it again for the remainder of the treatment.
