hello
pyorrhoea what we call it in general terms is
gingivitis or
periodontitis if it is associated with bleeding and bone loss
what i would suggest is that you pay a visit to your nearby
dentist who will get the scaling and curretage done which is proper treatment for this
in the mean while you can do the following
1.luke warm saline rinses 6-8 times daily
2.use some gum
astringent such as hiora or fitgum after every rinse on the gums
3.use antiseptic mouthwash like hexidine after breakfast and do not rinse after that for atleast 30 min
remember to brush and rinse after dinnner before going to bed
now for your other query about flap surgery
it is advisable when
gingival recession is very advanced with bone loss and mobile tooth.Although flap surgery is a very good option but is advvisable in very advance case because of two reasons viz
1.very costly , may cost 1000-2000 rs per tooth in india
2.invasive procedure
so pay a visit to your dentist and he will advise you suitably
hope that helps
