When the mouth is not used to having an appliance in it at all times, it can result in awkward speech. So like most oral appliances, Invisalign requires patients to undergo an adjustment period. Some patients report a small lisp or difficulty with proper pronunciation, but these speech difficulties typically go away after the patient acclimatizes to the aligner, which can take several weeks.   If you are looking for a quality and trusted Invisalign provider, come to Great Smiles Family Dentistry!
