Expanders often take a week or two to adjust to. You may feel like you are talking funny and that you are swallowing differently. This will improve with time. Make sure that you are getting enough calories in your diet as the
expander does tend to impact the amount of food you consume. At 101 lbs, I doubt that you have many extra pounds to lose. In a case that is borderline bicuspid extraction, utilizing an
expander may help reduce the time that you are in orthodontic treatment allowing the
orthodontist to treat you nonextraction. Generally, extraction treatment usually takes longer. Maxillary expansion can also produce a wider smile that is even more esthetically pleasing. Also, at 18 years old, it is possible that you may not achieve true skeletal widening of the upper jaw which could impact the amount of time that you wear the
expander. Hang in there and keep smiling!!!
