Getting teeth cleaned every 6 months is just
like you taking a professional care of your face, hair etc. Cleaning dosnt create gaps. Cleaning removes tartar from inbetween the teeth and if you maintain that cleaniness your gum will fill up that triangular gap. -care all you need is two times brushing
-restrict in between meals
-decrease the frequency of sugar
-rinse your mouth everytime you have something even after all this you might be needing a professional cleaning once a year because after you have your meal their is a deposition of a layer on your teeth which is called plaque. That plaque if not removed turns into calculus
(tartar) professional cleaning remoces tartar.
