You need to trust the doctor who has performed the clinical examination and seen the X-ray of the tooth, because he is the best judge to arrive at the right diagnosis and devise the right treatment plan. We cannot provide a rational suggestion without a look at the clinical condition of the tooth and evaluation of the X-ray.
But if we assume that the decay is deep enough, as is also likely based on the symptoms that you have mentioned, root canal treatment is the only permanent solution to avoid extraction of the tooth.
