What are the characteristics of the best transparent aligners as described by Carolyn Scott?

The best transparent aligners, as I describe them, have a few key characteristics:

• Almost invisible: Hardly visible to the naked eye, so you can smile and socialize without feeling self‑conscious.
• Comfortable and gentle: No brackets or wires; they gently push teeth into place and are less irritating to gums.
• Removable: Easy to take out for eating, brushing, and flossing, which helps maintain good teeth and gum health.
• Lifestyle friendly: No major food restrictions and generally a quicker, more convenient path to a straighter smile than traditional braces, especially for mild to moderate issues.
