Not in theory ... First of all, let's talk about the firmness ... Our teeth are not simply inserted in the bone (many people think so). The fixation of teeth mainly depends on periodontal ligament ... When shaping (that is, correcting), the doctor will exert a continuous and gentle force on the teeth (usually through arch wires, rubber chains and the like). The alveolar bone is very soft ... it is very renewable ... The direction of stress will cause the alveolar bone to absorb ... Then there will be a vacancy ... The teeth can move ... The original position will be filled by the regenerated alveolar bone ... but be careful not to push too hard at once. ....

Theoretically, it doesn't matter whether the gums open or not ... but after wearing braces ... you should brush your teeth carefully and patiently ... because something prevents you ... it won't be clean after a long time ... of course it will have an impact ... but according to the time calculation, it will take about 1 year to find a correction ... It usually has an impact ... and it can be recovered later (it seems a bit irresponsible). ....
