Should an old milk tooth be pulled?

I'm 43 years old and i still have one milk tooth because there is no normal tooth under there, it's a defect i was born with i guess. I did a blood test and it showed my white blood cells are not right. I probably have an infection somewhere and i suspect it has to do with my teeth.
When i looked at a recent x-ray of my teeth, i saw that the milk tooth does not seem to have a root anymore.

I can't remember if i ever had a root canal done but when i looked at the x-ray i did not see any white looking roots, (which is what a root canal tooth looks like on an x-ray i think, after searching on google images). So i think i'm good and probably never a had root canal done.

So could this milk tooth be causing my problems? Does it have a similar effect as a tooth that had a root canal done? In other words, is there a dead tooth in my mouth that needs to be removed?

Thank you.

If its just a dead tooth and no nearby gum soreness or inflammation then I can't really see an inanimate object like a tooth thats stands alone not connected to anything with a root being a problem. You dont wanna lose too many teeth. You need them for eating lol. But if you got lots then it wouldn't hurt to pull it just in case.

Well actually i had 2 milk teeth with nothing under there. One was pulled out so i have nothing there now, and if i pull this other one then i have 2 missing teeth. So i prefer to keep it, but if it needs to go then it needs to go. I'm worried about my white blood cells. My neutrophils were too low and my monocytes were too high. When i googled this all i can find is possibly leukemia, which freaked me out badly.

I also read that infected teeth and root canal problems can cause these white blood cells to get too high. When i push my finger under my jaw where the roots are, it does give me some pain, which tells me something might be infected there.

My family doctor told me i probably have an infection but she did not tell me anything else so she was not of much help. She is pretty stupid and brainwashed, she always tries to put me on statins for having a bit high cholesterol, so i don't take her very serious anyway.

I had this blood test done 2 years ago and i'm still here so i guess it's probably not leukemia. I need to get another blood test done but i was a bit scared for the result so i didn't go back. I first want to go to the dentist to see if i have a tooth or root infection and then i'll do another blood test and hopefully my blood work comes out better this time.

Unless there is a "hot spot" using a 3-D cone x-ray, wouldn't worry about it.

Leukemia is not difficult to treat (provided natural methods are used).

In any case if there are no swollen lymph nodes, enlarged liver or spleen, then probably nothing to worry about.
