Hey! I have been struggling with a headache for about a week. I find it very difficult to concentrate on my studies. But I had no idea that the cause of my headache is my cracked tooth. I went to my dentist in Whitby and he examined my tooth. He told me that my tooth got decayed and there is a chance of spreading the infection to other teeth. I have two options; root canal therapy which will remove the infected pulp and tooth extraction. Anyone of you had an experience with root canal therapy? I am afraid to undergo the treatment and I think I will go for tooth extraction. But then I have to undergo dental implant. I am confused. Can anyone of you guide me to take a decision?
