Over-the-counter pain medication and orthodontic relief wax/silicone will help alleviate any soreness and discomfort following placement of braces and orthodontic adjustment visits. 

Salt-water rinses are also an effective remedy and also chewing sugar-free gum, as this increases blood flow to the supportive structures surrounding the teeth which helps to reduce orthodontic soreness/discomfort and can also encourage the teeth to move/align quicker.
