We’ve turned into a Hive, things are getting serious.

Dude, bro. Teeth aren't the most important thing; they won't grow back, so the point is to preserve them. You definitely need to work out; how else will you improve what you already have? Only with fat, but you know that's not ideal. As for height, you really should try the Ilizarov apparatus. It personally helped me grow to 199, and then I grew another ten on my own. Diet: as many superfoods as possible. This includes chia seeds, avocado (a terrible fruit, but if you have to, you have to), broccoli, Greek (Ashotov) yogurt, raw carrots (yes, you eat them raw), Brussels sprouts, cheese, and eggs. It seems like it's all part of a diet, but if you have money, you can probably add some more protein. I don't have that much money, so I can't advise you, but intuitively, it could be chicken breast + salmon. Maybe trout. You should check this yourself.
