About Hygiene: Brush your teeth everyday 3 times a day with (at least 1000ppm fluor toothpaste, it buffs your teeth against demineralization).
Divide your mouth into sections, 6 works okay, imagine your teeth in 3D, it will have 5 surfaces of which 3 will be visible, occlusal or the one that bites, distal or the lingual/palatal or the inside surface and vestibular or the outside face (the one you see when you smile); make sure you spend 15 seconds brushing every surface for each pair of teeth. For the proximal (face frontwardish and not visible) and distal (backwardish and not visible) surfaces, not reachable by the brush, you'll want to use floss, and should floss at least once a day, preferably before you sleep, make sure to insert the floss 2 times and pull it out pressing 1 time against the proximal surface and the 1 time against the distal surface.
Finish it all of by using gauze to scrub and polish your teeth, it grabs and removes plaque with ease, focus on all visible surfaces.
Your gums should have a orange peel look when healthy and properly cared.
