Yes, the metal ring of the braces does press against the teeth. The metal ring is part of the bracket that is attached to the teeth, and it exerts pressure to help move the teeth into the desired position. This pressure is necessary for the braces to be effective in straightening the teeth, but it can also cause some discomfort or soreness, especially after adjustments. However, the pressure is carefully controlled by the orthodontist to ensure that the teeth are moved gradually and safely. **

To open an iron key ring, you can use a small, sturdy object such as a flathead screwdriver or a coin.
