Having done braces b4, i will just say that gums might bleed cos it might get more sensitive due to e treatment, n being pregnant ur gums will also be much more sensitive n possibly weaker, so i think u don't do braces now since this treatment gonna take u at least 2 years to complete..
Cleaning of ur teeth should be of no problem. Putting on braces I think u have to check with ur gynae 😉
It should be okay but if you have underlying health issues, do get advice from gynae
you can have oral prophylaxis but not you cant put on braces😊
Best to ask ur gynae, or ur dentist
check with the dentist
