Root canal treated tooth

It has been over a week since the root canal filling, and the area below the root canal tooth should be the alveolar bone or just beneath it.
If I apply pressure while using skincare products on my chin, I notice that the tooth that underwent root canal treatment feels different compared to the others.
Is this normal? Additionally, the area beneath the alveolar bone appears slightly red and swollen, but I do not experience any discomfort unless I apply direct pressure.
Does this indicate treatment failure, or could it be due to previous nerve necrosis affecting the bone? Aside from applying pressure, I do not have any other pain in that tooth, and I can eat and drink hot or cold without discomfort, and there is no pain during biting.

More Info

After undergoing root canal treatment, it's not uncommon to experience various sensations in the treated tooth and surrounding areas. The sensations you're describing—feeling different pressure or sensitivity when pressing on the area, along with some redness and swelling—can be attributed to several factors related to the healing process and the nature of the treatment itself.

Firstly, after a root canal, the tooth and surrounding tissues can be sensitive as they heal. The procedure involves cleaning out the infected or damaged pulp from inside the tooth, which can lead to inflammation in the surrounding tissues. This inflammation can manifest as tenderness or a different sensation when pressure is applied, especially if the area is still healing. It's important to note that some degree of discomfort is expected in the days and weeks following the procedure, and it typically diminishes over time.

The redness and slight swelling you mentioned could indicate that the area is still healing. However, if the swelling is significant or accompanied by persistent pain, it could suggest an underlying issue, such as an infection or an incomplete cleaning of the root canal system. In some cases, the inflammation can be a result of the body’s immune response to the treatment, especially if there was pre-existing infection or damage to the bone surrounding the tooth.

Regarding your concern about whether this indicates treatment failure, it’s essential to consider the overall context. If you are not experiencing significant pain during normal activities like eating or drinking, and the discomfort is only present when pressure is applied, it may not necessarily indicate a failure. However, the presence of redness and swelling should be monitored closely. If these symptoms persist or worsen, it would be prudent to consult your dentist or an endodontist for a thorough evaluation. They may recommend imaging studies, such as X-rays or a cone beam CT scan, to assess the condition of the tooth and surrounding bone more accurately.

In some cases, the nerve damage from the initial infection can lead to changes in the bone structure, which might contribute to the sensations you're experiencing. The bone may take time to recover fully after the infection has been resolved, and this healing process can vary significantly from person to person.

In summary, while some sensitivity and unusual sensations after root canal treatment can be normal, especially in the initial healing phase, it’s crucial to keep an eye on any changes. If you notice increasing discomfort, persistent swelling, or any new symptoms, it’s advisable to seek professional advice. Regular follow-ups with your dentist will help ensure that any potential issues are addressed promptly, and they can provide you with the best guidance tailored to your specific situation.
