Palatal expansion combines tooth movement and jaw expansion. It works by widening the two halves of the upper jaw, called the palate. These two halves are joined together with a suture in the middle of the roof of the mouth. Expanders are custom made for each patient and can either be fixed or removable. Expansion can take a few weeks to a few months, depending on the amount of expansion required for an individual patient. The best timing for palatal expansion is usually between the ages of 7 to 9.
The palatal expansion will improve the way the upper and lower jaw function. Expanders widen the jaw, so there is more room for permanent upper and lower teeth to come in. If left untreated, a narrow palate can lead to the need for excessive dental work later on. Most of the expansion can be accomplished within a month. To ensure that the expansion is stabilized, the expander is generally left in the mouth for about 6 months. Most patients require full orthodontic treatments such as braces following palatal expansion.
It may take a few days to get used to having a palatal expander. Chewing, swallowing, and speaking may initially be uncomfortable. Some patients experience soreness of the mouth, nose, and even some tingling. In rare instances, a mild headache may be experienced. After a few days with the expander, patients may notice a space between their front teeth. This is a wonderful sign that demonstrates that the appliance is working and the palate is expanding.
The expander should be brushed whenever teeth are brushed. Patients should rinse their mouths with water right after eating and also after drinking a beverage with sugar. Removable expanders should be brushed and rinsed each time the appliance is taken out of the mouth.

"I absolutely loved my experience with Dr Chang! She explained everything that I didn’t have any questions. She understood my orthodontic needs and was able to make an Invisalign treatment that fits my needs."
"Great orthodontist!"
"She has a strong focus on customer service! ...helped me with a slight misalignment - something that the DC orthodontist did not even mention!"
"It is with great pleasure that I whole heartedly endorse Dr. Donna Chang! At the age of 60...She was able to give me several viable options to pursue."
"Dr. Chang is thorough and listens closely. I came in for a consultation and she recommended that I did not need orthodontia work. So she didn't do any orthodontic work for me but my husband used her for Invisalign treatments and was very happy with his experience."
"Dr. Chang is a wonderful orthodontist! Skilled, caring, and highly ethical."
"Dr. Chang is absolutely incredible! I love how accessible, personalized, and accommodating my orthodontic treatment was, especially during the pandemic. Dr. Chang makes you feel important and cared for as a patient. I couldn’t recommend her enough!"
"Dr. Chang is highly personable and knowledgeable. I have been to a few orthodontists in the past, and I have never met someone who greets her patients the moment they walk into the room and walk them through the entire process. From the general examination to the quotes and paperwork, Dr. Chang explained every detail to me. I emailed her after the appointment, and once again was met with the greatest considerations and thoroughness. After meeting her for the first time, I have decided to start the procedure."
