Hi,
Thanks for asking the query,
Infection of the gums mainly occurs due to poor
oral hygiene, plague and calculus deposition.
Bacterial and viral infections worsen the condition. Use of some medications,
hormonal changes systemic conditions like
diabetes, vitamin deficeincy, habit such as smoking can also lead to such changes.
I would suggest you to take your daughter to
Dentist and get the thorough checkup done, take an OPG radiograph, go for symptomatic treatment of complete mouth scaling and polishing.
Maintain a good oral hygiene, use lukewarm saline rinses and antiseptic mouthwash gargles twice daily.
Start with
multivitamin tablets.
Take complete balanced diet with lots of water.
Hope this helps out.
Regards...
