There is no proof for mewing, so that's a great start to misinterpreting studies for your own personal gain and cope. https://www.health.com/mewing-7098082
For orthodontic treatment, it does show substantial proof that it works. But let's look at the methodology.
To begin with, the control group did NOT receive any supplemental Vitamin C

This automatically makes it uncomparable or useful to megadose such Vitamin C supplements or dietary Vitamin C.

Vitamin C deficiency, is extremely rare. So comparing rats who consumed no Vitamin C compared to ones who did, is frankly useless.

"This study assessed >22,400 participants (aged 40–79 years), revealing a weighted mean of 54 µmol/L vitamin C (48 and 59 µmol/L for men and women, respectively), and a prevalence of deficiency of 1.4% (2.2% for men and 0.8% for women)."
So, if you consume the RDA for Vitamin C, it's unlikely you will require "megadosing" absolutely anything for orthodontic purposes, and isa waste.
While vitamin C is low toxicity, it can cause some issues when receiving over the recommended dose.

Significant sources of Vitamin C in food (if you are not receiving sufficient amounts, which COULD lead to slower orthodontic progression)

Unlike Vitamin C supplements that only contain Vitamin C, these foods are multi faceted.
