Tooth and Mouth Problems

I extracted my 7th upper decayed teeth through dentist but some portion of teeth left there nearly of few mm in bottom.Dentist said gum will overcome that teeth.so is there any problem with that left decayed few mm teeth inside gum or should it be removed completely

I have a swelling and pain in the gum near my root canal tooth... i had a few days ago and it subsided with medicines.. the swelling and pain had again emerged.. i got an xray done but does not show any infection... plz advice

It has been 20 days to rootcanal and having headache from filling . Pressured head,little dizziness and tingling in left eye.i ask to dentist he told me it will be normal after capping but not going to stop what can be reason i dont have such pressure and headache before. What should i have to do now?

I have teeth problem , gum bleeding, i am using stolin gum paint, its ok ,pls give me advise,its for 3 yrs,

How we can know whether root canal is necessary for teeth or not and when we actually required root canal and cap is necessary after root canal

My tooth is numb I think. It doesnt feel hot or cold. Are all teeth supposed to feel something when I eat?

I am having pain on my left molars for past few days...it seems my gum os also swollen at that place..can u advice some domestic remedies?
