Bite Issues After Root Canal Treatment: Causes and Solutions

Root canal treatment for dental occlusion issues?

Hello Dr.
Huang: I had a root canal treatment on my lower right molar at the end of November last year, but I have gradually noticed that the occlusion of my lower right teeth feels higher.
I asked my dentist about it, and he said it’s unlikely to happen.
Since I am still undergoing treatment, the doctor mentioned that he could help adjust my occlusion.
However, I did not have this issue before the treatment, so I would like to find out what possible causes might be.
I did some research earlier and found that possible reasons for the sensation of elevated teeth could be: bacterial or chemical apical periodontitis and gingivitis (pulpitis).
I would like to ask Dr.
Huang if my symptoms could be related to this.
Thank you.

Dear Ms.
Valis,
Hello! As mentioned, it is indeed quite special; essentially, during root canal treatment, there may be edema at the apex, which can cause an increased occlusal sensation in the tooth, or there may be periodontal disease.
Please communicate more with your physician! Thank you! Wishing you peace!
Sincerely,
Dr.

More Info

Understanding bite issues after root canal treatment can be quite complex, as several factors can contribute to changes in occlusion (the way your teeth come together when you bite). It’s important to address your concerns thoroughly, especially since you’ve experienced a noticeable change in the height of your bite following the procedure.

Firstly, it is crucial to understand that root canal treatment (RCT) is performed to remove infected or damaged pulp from inside the tooth, followed by sealing the tooth to prevent further infection. After RCT, some patients may experience changes in their bite, which can be attributed to several reasons:
1. Inflammation and Healing: After a root canal, the surrounding tissues may be inflamed. This inflammation can lead to temporary changes in how your teeth align when you bite down. If there is any residual infection or inflammation, it can cause discomfort and may alter your perception of bite height.

2. Changes in Tooth Structure: During the RCT, the dentist removes the pulp and may also need to remove some tooth structure to access the canals. If a significant amount of tooth structure is removed, it can affect how the tooth fits into the bite. Additionally, if a crown or filling is placed on the tooth after RCT, it may not be perfectly adjusted to your bite, leading to a feeling of increased height.

3. Bite Adjustment: It is common for dentists to perform bite adjustments after RCT, especially if the tooth has been restored with a crown or filling. If your dentist has indicated that they can adjust your bite, this is a positive step. An improper bite can lead to discomfort, jaw pain, and even headaches.

4. Underlying Conditions: As you mentioned, conditions such as apical periodontitis (inflammation at the root tip) or periodontal issues can also contribute to changes in bite. If the root of the tooth is still infected or if there is inflammation in the surrounding gum tissue, it can affect how the tooth feels when biting down.

5. Psychological Factors: Sometimes, the perception of a "high bite" can be influenced by anxiety or discomfort associated with the dental procedure. If you are feeling anxious about your treatment, it may heighten your awareness of how your teeth come together.

To address your concerns, it is advisable to follow up with your dentist regarding the bite adjustment. They can assess the occlusion and make necessary adjustments to ensure that your bite feels comfortable and natural. If your symptoms persist, further investigation may be warranted, including X-rays or possibly a referral to an endodontist (a specialist in root canal treatments) for a second opinion.

In conclusion, while it is possible that your symptoms could be related to inflammation or other dental issues, it is essential to communicate openly with your dentist about your concerns. They can provide a thorough examination and tailor a treatment plan that addresses your specific needs. Remember, effective communication with your dental care provider is key to achieving the best possible outcome following root canal treatment.
