A pad helps fix your teeth on the mouthpiece. Without it, the teeth will slip and leave marks on the mouthpiece, which is the most fragile and fairly expensive part. Pads are rarely included with the mouthpiece.
If applied correctly, a pad can last for a year or even longer. Usually it is replaced once every couple of years.
Previously, pads were not so common; electrical tape or other improvised materials were used to fix the teeth. Now you can buy pads in any wind instrument store or on marketplaces.
