Hi, I need a root canal treatment. My lower left side teeth are infected and I think the only root canal treatment can help me. But I don't have any idea about this treatment. I'm scared about the procedure. I'm experiencing prolonged sensitivity to cold foods. I tried painkillers and they could only give a temporary relief. Last night, I went to a party and I could not eat anything due to the severe pain. I was starving for the whole night. Today morning, I noticed the discoloration of the tooth, which is infected. Also, there is swelling and tenderness in the nearby gums. Things get worse day by day. When I shared everything with my colleague, he suggested about a dental clinic in Whitby which provides the best dental services ( appletondental.ca/services/ ).How long does root canal treatment take? How should I take care of my tooth for it not to get infected? Please share your genuine replies.
