How Can You Detect An Ulcer Is There Some Sort Of Blood Test That Can Detect Blood Poisoning From Abscessed Teeth?

Is there some sort of blood test that can detect blood poisoning from abscessed teeth? - how can you detect an ulcer

I have on 1 Held in October, thank God. I have two broken molars, are forfeited and are therefore less well developed both on the gums, and both have holes that collect large amounts of food. I try to keep it clean, but not always. Now I am in great pain. I also have an upper tooth is cracked, and if the gums are inflamed, they looked through the crack in the teeth. Abscesses often.

I think it could be a type of blood poisoning, because I always feel ill, I have a lot of stomach pain (ulcer) pain, I feel a headache the whole time and my body is still tight and as much pressure on my body.

Is there a blood test that I can ask around to check for blood poisoning in my system?
