Hi today we're going to talk about symptoms of a Root Canal infection. I'm Dr. David Wagner, NorthWood Dental; Clearwater, FL., and what are the symptoms of a Root Canal infection? A Root Canal is when you have an infection that starts in the tooth, spreads down to the root, and gets into the bone underlying the root. This infection can actually swell or spread and creates pressure which radiates to the jawbone, so that would be part of the pain or the most severe pain you could have would be the radiating of pain through the jawbone. It actually can feel like it's going from, you don't even know which tooth it is because it goes through the entire jaw. so it's very common for a patient to come in say "I don't know which one it is, but it really hurts." Now before that occurs sometimes you'll feel sensitivity because of the hole in the tooth gets down to the nerves so hot and cold and sweets will actually cause a problem. Now it may be a cavity or it may be the beginning of a root canal. Sometimes when the infection's inside the tooth hot or cold can make it worse or better. I've actually seen where hot will make it feel worse and cold will make it feel better. This is a very good sign that you're having an infection inside the tooth. This has to do with the expansion and contraction of the tooth and the nerve inside. So sometimes though it's very evident, because it'll actually be swelling and even some pain and puss drainage right beside the tooth that's affected so, that makes it pretty easy to see which tooth it is there. So those are some of the symptoms of a Root Canal. I'm Dr. David Wagner, NorthWood Dental; Clearwater, FL.
