How To Deal With Pressure Pain On Root Canal Tooth?

By Kendra Reed

Updated On

A root canal is a dental procedure that involves removing the infected or inflamed pulp (soft inner tissue) from the center of a tooth. While root canal treatment is generally effective in relieving pain and saving the natural tooth, some patients may experience pressure pain or discomfort after the procedure. Dealing with pressure pain on a root canal tooth can be challenging, but there are various ways to manage it effectively and find relief.

Causes Of Pressure Pain On Root Canal Tooth

Pressure pain on a root canal tooth can arise due to several reasons. One common cause is inflammation or infection in the area surrounding the treated tooth. Even after the root canal procedure, residual inflammation or bacterial presence can lead to pain and sensitivity. Additionally, improper bite alignment or occlusion (the way the upper and lower teeth fit together) can put excessive pressure on the treated tooth, causing discomfort.

Pressure Pain On Root Canal Tooth

Another potential cause of pressure pain is the formation of a localized infection or abscess in the bone surrounding the root of the tooth. This can occur if the root canal treatment was incomplete or if the infection was particularly severe. In some cases, the pressure pain may also be related to the temporary or permanent dental filling or crown placed after the root canal procedure.

Tips For Managing Pressure Pain

  1. Over-the-counter pain medication: Taking over-the-counter pain relievers, such as ibuprofen or acetaminophen, can help alleviate pressure pain on a root canal tooth. Follow the dosage instructions carefully and consult your dentist if the pain persists.
  2. Cold compress: Applying a cold compress or ice pack to the outside of the cheek near the affected tooth can help reduce swelling and numb the area, providing temporary relief from pressure pain.
  3. Soft-bristled toothbrush: Use a soft-bristled toothbrush and gentle brushing techniques to avoid further irritation or discomfort in the treated area.
  4. Dietary adjustments: Avoid hard, crunchy, or sticky foods that can put pressure on the affected tooth. Stick to a soft, nutritious diet until the pressure pain subsides.
  5. Salt water rinses: Rinsing your mouth with warm salt water can help reduce inflammation and promote healing, potentially alleviating pressure pain on the root canal tooth.
  6. Dental wax or cotton: If the pressure pain is caused by a temporary crown or filling, placing dental wax or cotton over the area can provide a buffer between the tooth and your bite, reducing the pressure.

Preventive Measures

To avoid pressure pain on a root canal tooth and ensure the long-term success of your treatment, it’s essential to follow preventive measures:

  1. Maintain good oral hygiene: Brush and floss regularly to prevent the buildup of plaque and bacteria, which can lead to infection and inflammation.
  2. Attend regular dental check-ups: Regular visits to your dentist allow for early detection and treatment of any dental issues, reducing the risk of complications after a root canal procedure.
  3. Address dental problems promptly: If you experience persistent pain, swelling, or discomfort after a root canal treatment, seek professional dental care immediately to address the underlying issue.
  4. Follow post-treatment care instructions: Your dentist will provide specific instructions for caring for your root canal tooth after the procedure. Following these guidelines carefully can help ensure proper healing and minimize the risk of pressure pain or other complications.

Dealing with pressure pain on a root canal tooth can be unpleasant, but it is a manageable condition. By understanding the potential causes, implementing effective pain management strategies, and following preventive measures, you can find relief and ensure the long-term success of your root canal treatment. If pressure pain on the root canal tooth persists or worsens, it’s crucial to consult your dentist promptly. Taking proactive steps to manage pressure pain and prioritizing your oral health can help prevent future issues and maintain a healthy, comfortable smile.


1. How long does pressure pain on a root canal tooth typically last?

The duration of pressure pain on a root canal tooth can vary from person to person and depends on the underlying cause. In most cases, the pain should subside within a few days to a week after the treatment. However, if the pain persists for more than a week or worsens, it’s essential to consult your dentist for further evaluation.

2. Can pressure pain on a root canal tooth indicate a failed root canal treatment?

Persistent or severe pressure pain on a root canal tooth may be a sign of a failed or incomplete root canal treatment. In such cases, the infection or inflammation may have persisted, requiring additional treatment or retreatment of the affected tooth.

3. Is it normal to experience pressure pain when biting down on a root canal tooth?

It is common to experience some discomfort or pressure pain when biting down on a root canal tooth, especially in the days immediately following the procedure. However, if the pain is severe or persists for an extended period, it may indicate an issue with the bite alignment or occlusion, which should be addressed by your dentist.

4. Can pressure pain on a root canal tooth be a sign of a cracked or fractured tooth?

Yes, pressure pain on a root canal tooth can sometimes be a symptom of a cracked or fractured tooth. If the tooth structure is compromised, it may not be able to withstand the normal biting forces, leading to pain and discomfort. Your dentist can evaluate the tooth and recommend appropriate treatment options, such as a dental crown or extraction, if necessary.

5. What should I do if the pressure pain on my root canal tooth is accompanied by swelling or fever?

If you experience pressure pain on a root canal tooth along with swelling, fever, or other signs of infection, it’s crucial to seek immediate dental attention. These symptoms may indicate the presence of an abscess or a more serious infection that requires prompt treatment to prevent further complications.
