If you wear a retainer to correct the alignment of your teeth will shape jaw change permanently?

In some cases, retainers can change your jaw shape permanently, but it depends on individual oral development, growth, and the specific circumstances of your treatment.

Here's how retainers can affect jaw shape:

Jaw expansion: Retainers used for expanding the palate or arch of the jaw, particularly during early stages of growth, can create a gradual change in the shape and width of the jaw.

Correction of Jaw Misalignments: If used to correct certain types of jaw misalignments, such as crossbite or overbite, retainers can exert gentle pressure to shift the jaw into the desired position, leading to permanent changes in jaw shape.

Jaw Stability Maintenance: Retainers are also used after certain orthodontic treatments to maintain the achieved results and prevent teeth from shifting back. In this sense, they can help preserve any positive changes made to the jaw's shape and alignment.

However, it's essential to note that retainers' impact on jaw shape is more significant during the growth phase, typically for younger individuals. Adults might experience subtler changes or may require more advanced treatments for significant changes to their jaw structure.

It is always advisable to consult with an orthodontist to understand how retainers can specifically impact your jaw shape based on your individual situation and treatment needs.
