Eli5: Why is it that your gums bleed when you brush your teeth for the first time in a couple days or more?

Edit: Sake of clarity, I suffer from a litany that all impact executive functions. As much as I regret to admit it, the extent of my personal hygiene is making sure my hair don’t dry Tf out or get too oily, and making sure I don’t smell like shit. Bare minimum. I’m an unkempt and wild looking person, which makes people tend to avoid me; which I personally don’t mind at all. However I’m fully aware that I have many issues which need working on. They’re holding me back in many ways, neglecting my body and my living space even worse. Didn’t mean to give a sob story lol, just to explain as to why I have issues like this.

With the additional bacteria in your mouth, your body reacts by making your blood vessels more leaky to allow white blood cells from your immune system to leave the blood and go to the gums. Since they are leaky, any manipulation to them also squeezes out some blood. Once your teeth are clean and bacteria gone, your blood vessels seal up and won’t leak blood.
