An MSE palate expander is a type of orthodontic appliance used to widen the upper jaw. MSE stands for "Maxillary Skeletal Expander". The appliance is made of titanium and is attached to the palatal bone with screws. Then the screws are used to expand the device to the needed extent.

When activated, they gradually widen the palate over time. This expansion creates more space for crowded teeth and improves breathing and facial aesthetics.

How Does MSE Palate Expander Work?

The MSE palate expander works by applying a controlled amount of pressure to the upper jaw. This pressure stimulates bone growth, allowing the palate to expand gradually. 

Overall, the MSE palate expander can be an effective orthodontic treatment for patients who need to widen their upper jaw. However, the device may cause some discomfort during the initial adjustment period.

A maxillary expander may be recommended by an orthodontist for a variety of reasons, including:

  1. Crowding of the teeth: If a patient has crowded teeth, widening the upper jaw can create more space and make it easier to align the teeth properly.
  2. Crossbite: A crossbite occurs when the upper teeth bite inside the lower teeth, instead of the opposite. Expanding the upper jaw can help correct a crossbite.
  3. Breathing difficulties: In some cases, a narrow upper jaw can contribute to breathing difficulties, such as sleep apnea. A palatal expander can help widen the jaw and improve breathing.
  4. Speech problems: A narrow upper jaw can also contribute to speech problems, such as a lisp. Expanding the jaw can help improve speech.
  5. Aesthetics: Finally, a narrow upper jaw can contribute to an unattractive smile. Widening the jaw can improve the appearance of the teeth and overall facial aesthetics.

Can Mewing Be an Alternative to MSE Palate Expander?

Both mewing and MSE expander aim to improve facial structure and dental health. Yet they are different in their approach and effectiveness. Mewing is a non-invasive technique that involves keeping proper tongue posture. While an MSE is a dental appliance that applies pressure to the upper jaw to widen it.

Check out our collection of mewing before and after results.

Mewing is effective for minor and medium jaw alignment and dental issues. While severe cases of teeth misalignment or jaw issues, just mewing isn’t enough. That’s where a dental professional figures out the best treatment with the use of an MSE or other orthodontic appliances. 

However, mewing is still worth trying, whether there’s any jaw or dental issue or not. When you mew properly (learn how to mew if you haven't yet), your tongue is in a natural position - pressed up to the roof of the mouth. It allows you to maintain a good facial structure, and avoid dental and breathing problems.
