A root canal is a common procedure used to save a damaged or infected tooth, but it doesn’t always guarantee immediate relief from discomfort. If you’ve recently had a root canal and experience pain when pressure is applied to the treated tooth, it can be concerning.
In this blog, we will explore the possible reasons for pain after a root canal, what it could mean, and how Legacy Dental can help you address it.
A root canal is a dental treatment designed to repair and save a tooth badly decayed or infected. During the procedure, the infected pulp (the soft tissue inside the tooth) is removed, and the tooth is sealed to prevent further infection. Root canal treatment can often eliminate pain and restore a tooth’s function, but some patients may experience discomfort afterward, particularly when pressure is applied to the tooth.
At Legacy Dental, we use the latest techniques and technologies to make root canal procedures as effective and comfortable as possible. If you are experiencing pain after a root canal, it’s important to understand what might be causing the issue and how we can help.

There are several reasons why a tooth that has undergone a root canal may hurt when pressure is applied. Here are some common causes:
It’s normal for the surrounding tissues to be inflamed after a root canal. This inflammation can make the tooth sensitive to pressure, especially when chewing or biting. This discomfort typically subsides a few days to a week after the procedure as the body heals.
At Legacy Dental, we ensure you are fully informed about post-procedure care and what to expect during recovery. If pain persists, we will evaluate the area to ensure proper healing.
In some cases, a tooth may become reinfected after a root canal. This can happen if bacteria are not completely removed during the procedure or the tooth becomes re-contaminated after the treatment. An infection can cause throbbing pain, swelling, and discomfort when pressure is applied to the affected tooth.
If you experience persistent or increasing pain after your root canal, it may indicate that the infection has not been fully treated. Legacy Dental offers thorough follow-up care to ensure the procedure’s success and address any potential complications.
A tooth that has undergone a root canal may be more susceptible to fractures or cracks, especially if it was already weakened by decay before the procedure. A cracked or fractured tooth can cause sharp pain when pressure is applied, which may lead to discomfort when biting or chewing. A cracked tooth may require additional treatment, such as a crown or restoration.
At Legacy Dental, we take great care to preserve the structural integrity of your tooth. After your root canal, we will assess whether a crown or other protective measures are necessary.
Sometimes, if the root canal is not properly sealed, bacteria can enter the treated tooth and cause inflammation or reinfection. A poorly sealed root canal can result in pain when pressure is applied, especially during chewing. This issue may require retreatment to ensure the tooth is adequately sealed and infection-free.
At Legacy Dental, we take extra precautions to ensure that your root canal is properly sealed to prevent future issues. However, if you experience pain after the procedure, it is important to seek professional care.
If a crown is placed over your tooth following a root canal, an ill-fitting crown or one that has become loose can cause discomfort when applying pressure. If your crown doesn’t fit properly, it can affect how you bite down on the tooth, leading to pain and sensitivity.
Legacy Dental offers same-day crowns using advanced technology, ensuring a precise and comfortable fit. If you suspect your crown may be causing the issue, we can evaluate it and make necessary adjustments.

Some mild discomfort after a root canal is normal, but your dentist should evaluate persistent pain to rule out complications.
Most patients experience pain for a few days to a week. If pain persists longer or worsens, it may indicate an issue requiring further attention.
Contact your dentist to have the tooth evaluated for issues such as a poorly sealed root canal, a cracked tooth, or a problem with the dental crown.
Sometimes, a root canal can fail if the infection isn’t completely cleared or the tooth isn’t properly sealed. Additional treatment may be needed to correct the problem.
Following your dentist’s aftercare instructions, avoiding pressure on the treated tooth, and attending follow-up appointments are key to preventing pain after the procedure.
