Daughter has just been to the dentist and told she has tandvleesontsteking - what is this?
Gingivitis - http://en.wikipedia.org/wiki/Gingivitis
Oooooh, sounds horrible but isn't serious is it? How is that cured, does she have to have dental treatment to get it treated?
you get gingivitis because of the way of brushing/ cleaning yourselves. The dentist or the dental hygienist can help her to learn brush better. sometimes it is necessary to clean her teeth, to remove the tartar
