According to the American Association of Endodontists AAE , certain circumstances may prevent a tooth treated with a root canal from healing properly: If the dental professional misses tiny, hidden canals or curved canals during the first treatment, the bacteria inside them may not be entirely removed and can cause infection.
Immediately after the root canal, the dental professional often places a temporary filling to provide a short-term seal for the root canal before placing the permanent restoration such as a crown or filling. If there is a delay in placing the permanent restoration, there is a greater chance that the root canal can get reinfected.
If bacteria in the saliva get under the filling material before the filling is placed, the canal can become reinfected. If the patient doesn't maintain proper oral hygiene, new cavities can form on the same tooth that already received a root canal. A filling or crown placed on the tooth that received the root canal can crack, loosen or break, allowing a new infection to start.
Symptoms of Lingering Endodontic Problems When any of the previous circumstances occurs with your root canal tooth, you may experience a range of symptoms. Here are some signs that indicate it may be time to make an appointment with your dental professional, according to the AAE : Sensitivity to hot and cold, or lingering pain after consuming hot or cold food Sharp pain when biting down or when tapping the teeth together Constant pain and pressure Swelling of the gums, with or without the presence of a pimple-like bump near the tooth on the gums A dull ache experienced consistently in the same area These symptoms indicate there may be an issue with the pulp of the tooth, which is the interior portion of the tooth treated by a root canal procedure.

If you do have a root canal infection, learn to recognise the signs so you can receive prompt attention and your dentist can remove the infection through a root canal treatment. A root canal infection can start when your teeth are severely decayed or experience trauma. This damage allows harmful bacteria to seep into the roots of your tooth and reach the tissue inside called pulp. The pulp is made up of sensitive tissues and nerves. The pulp is what provides nourishment to the tooth when it is growing and erupting from your gums.
While the pulp stops serving its purpose when your teeth are fully grown, there is rarely any reason to remove it unless it becomes infected. When the pulp becomes infected, the bacteria may spread to other areas of the mouth. The bacteria begin to spread rapidly after infecting the pulp and can lead to abscesses, gum infections, and discomfort throughout the jaw, so it is in your best interest to seek an assessment and if necessary undergo a root canal treatment to save your tooth from extraction.
You may begin to notice that you have a root canal infection if you are experiencing discomfort while biting down or if your teeth are unusually sensitive to extreme hot or cold temperatures. Root canal infections also cause the infected tooth to darken and lose its natural sheen. The tooth may appear gray and dull. If an infection is allowed to persist without intervention, the tooth will eventually turn black. The discomfort you may experience from the root canal infection can be very severe.
The discomfort increases as the infection progresses and spreads to different parts of the mouth and possibly other teeth and your jawbone. It is very common for gums to become irritated and swollen as a result of a root canal infection. The swelling is generally only surrounding the infected tooth, but if the infection spreads, the inflammation in the gums can spread as well. Dental abscesses are perhaps the most uncomfortable of the symptoms that can arise when dealing with a root canal infection.
A dental abscess is a combination of dead pulp and bacterial elements that build at the tip of your tooth root underneath the gums. The infected pulp and bacteria cause pockets of pus and fluid to form, resulting in the dental abscess. The dental abscess appears like a large sore or pimple on your gums.
Dental abscesses can be very tender.
