Thanks for writing in.
I read your problem,it seems that you have gingivitis
,this is because of deposits on the teeth/resotoration/gums surface in the oral cavity.
So i will suggest you please visit a dentist
as soon as possible and get the scaling done and follow all the given instructions after scaling like-
1.Brushing twice daily with soft tooth brush.
2.use chlohex plus mouthwash for 15 days and discontinue it after 15 days.etc.......
Meanwhile you can perform warm saline gargles 2-3 days.
Nothing to get worried.
