Around 2 years back, one of my backtooth got cavity and now it is nothing, means it has a big hole and we can say that only small border and roots are remained. My dentist told me that we must have to do root canal. But every time he just fills cement in it and says we can push further. I filled cement almost 3-4 times and whenever it get removed, tooth starts aching. So yesterday I went and he said again we have to do root canal but told me today to came, I went and as always he filled cement. I asked that when we will do root canal and stop this, he said we will see. I don't wanna loose that tooth and increase more infection. Is he doing good or bad, or it is necessary??
Thanks
