Expanders dental can be used in children and adults, and they come in various types and sizes depending on the specific condition they are designed to correct. In this article, we will explore the different types of expanders dental, how they work, who needs them, and the benefits and risks associated with their use.

What is an expander dental?

An expander dental is a device that is placed in the mouth to widen the palate or upper jaw. It is usually made of metal, plastic, or a combination of both and is designed to fit the individual's mouth. The device works by applying gentle pressure to the upper teeth and gradually expanding the palate over time. This creates more room in the mouth, allowing for the proper alignment of teeth and a more comfortable bite.

How does an expander dental work?

The expander dental works by using a small screw mechanism that applies gentle pressure to the upper teeth. This pressure is gradually increased over time, causing the jaw to widen. The device is usually worn for several months, during which time the patient may experience some discomfort, but this should subside as the jaw expands.
