How is dilation done?

Dilation is typically done in a doctor’s office or clinic. The doctor will insert a dilator, which is a thin, rod-shaped instrument, into the opening that needs to be widened. The dilator is gradually increased in size until the desired width is achieved.

Dilation can be uncomfortable, but it is usually not painful. The doctor may give you a local anesthetic to numb the area before dilating. You may also be given a sedative to help you relax.
