Thanks Suse for your detailed reply. I know I don't have gum disease as my dentist has been keeping an eye on this during my check-ups, it seems to be more of a 'genetic' issue, where the gums are naturally more receding in some areas of my mouth. I am a good flosser but it seems to be happening (receding) anyway. I will see my dentist soon, but am nervous about what they can do about it, esp when ttc. Thanks again.
