Most patients describe Invisalign as comfortable, although some pressure may be felt when starting a new aligner. This pressure is a sign that the aligner is gently moving the teeth into their new position. The sensation usually settles within a few days as the mouth adapts. Because there are no brackets or wires, Invisalign often causes less irritation to the cheeks and lips compared with traditional braces. If any discomfort occurs our dentist at the Melbourne Smile Clinic in Northcote, can recommend simple ways to manage it while treatment continues.
