Similar to other cases discussed earlier, my back tooth was aching and dentist suggested root canal treatment, followed by crowning. I was a bit sceptical on this, because based on the condition of my tooth filing which is still good, no swollen gum or pus, fever, except for pain. I wonder on what ground the dentist make such judgement and recommendations.

While looking for second opinion, I am taking the prescribed antibiotics, which doesn't seem to help much. ALthough not constantly pain, but I still can't chew using the affected tooth

Anyone could shed some light?
