Thanks for asking the query,
When you have braces on your teeth the Orthodontist will advise you to maintain a good oral hygiene
so as to ensure that you keep your gums healthy. The best of brushing ans flossing techniques when used along with the braces on will ensure that your gums are not swollen.
Deep ultrasonic scaling followed by the course of antibiotics is required, use chlorhexidine
mouthwash rinses twice daily.
For gingival hyperplasia
i would advise you to get an OPG done to rule out extent of infection or boneloss if present and plan an appropriate treatment.
Hope this helps out.
