Root canal treatment helps save millions of teeth every year, treating decay and infection deep within the tooth structure. But, like any medical treatment, there can be complications — and sometimes, those complications lead to root canal failure and a need for retreatment.
Root canal failure typically happens when decayed material and bacteria remain behind after the procedure, sometimes due to complexities in the root canal structure. Other times, an initial root canal simply doesn’t heal properly, or a loose crown allows bacteria to enter the tooth and cause a new infection.
Like an initial root canal, retreatment works best when performed early. And that relies on recognizing the signs and symptoms that could mean you need another treatment.
The team at Compassionate Endodontists New York/NYC in New York City has extensive experience in root canal retreatment, using cutting-edge techniques to eliminate damage and preserve your natural tooth. In this post, learn what signs might indicate your root canal needs to be repeated.
Recurrent or persistent tooth pain is one of the most common and obvious signs that something is wrong with your tooth and often, an indication that you need retreatment. Typically, pain is worse when pressure is applied to the tooth or when you bite or chew with the tooth. Pain can range from mild to severe, depending on the severity of the underlying infection.
Swelling or bleeding in the gum around the tooth can be another sign that retreatment is needed. Like pain, swelling can be severe or mild, recurrent or persistent. It’s often accompanied by tooth pain or sensitivity.
Root canal treatment removes the main nerves inside the tooth, but that doesn’t mean all sensitivity is eliminated. If the tooth becomes reinfected, nerves surrounding it can become irritated, leading to pain when the tooth is exposed to hot or cold temperatures.
An abscess is a pocket of pus that forms in an infected area. Abscesses lead to localized swelling and significant pain. Without prompt treatment, an abscess can cause serious complications, including widespread infection.
The bacteria that cause tooth infections release foul-smelling byproducts as they grow and multiply. These byproducts cause bad breath that hangs around even if you brush and use mouthwash. You might notice a sour or unpleasant taste, as well.
Some failed root canals cause symptoms that extend beyond the immediate area of the treated tooth. In these instances, you might have facial swelling or pain in your jaw or ear. You may also develop a fever or flu-like symptoms in response to the infection.
