Hi. Yes the space can be closed here only if you maintain your oral hygiene. Pyrrhoea indicates that there is some kind of negligence towards your oral hygiene.
Rinse your mouth properly after eating anything especially after eating soft, sugary and sticky foods.
Brush twice daily. Brushing at night time before going to bed is a must.
Visit a dentist for Scaling/Cleaning of your teeth. He / She may prescribe you antibiotics as well.
