I'm curious as to which is better for the health of the tooth and gum, regular braces or invisalign?

Either one: If done properly and under supervision can maintain the health of the teeth and supporting structures. The expertise of the orthodontist, as well as you following directions and keeping your teeth clean is what is key.

Probably invisalign: Regular braces act as food traps, making oral hygiene difficult. They are also linked to root resorption, which does not occur frequently with invisalign.

Conundrum: While braces are harder to clean around, they do a better job positioning your teeth. The better tooth position, the better bone and gum position and contour. In the short run, invisalign. Over our lifetime, braces.

No difference: OK, there are some rare cases where we recommend invislaign while treating short root cases, but generally there is no difference on overall oral health between the two
