The magic ring cannot be tightened because it is already imbued with a fixed amount of magical energy and power. The enchantment placed on the ring during its creation determines its size and shape, and attempting to tighten it would disrupt the delicate balance of magic within the ring. Any alteration to the ring's structure could potentially weaken or even break the enchantment, rendering the ring useless. **

It is important to follow any post-tightening care instructions provided by your orthodontist to help alleviate any discomfort. **
