Dental anesthesia for cavity filling?

Hello, Doctor.
I noticed that you are very patient and thorough in answering questions in the Q&A section, so I would like to ask you something.
Recently, after having my lower horizontal wisdom teeth extracted, I discovered that my front molar had a cavity.
Since the decay was quite deep, some gum tissue was cauterized to facilitate the filling.
Before the procedure, I received a local anesthetic injection.
I consider myself to have a high pain tolerance, but during this particular injection, the pain I experienced was truly unprecedented.
It was so painful that I couldn't help but cry out (the pain was not from the needle insertion but rather from the process of injecting the anesthetic).
After having the filling done on July 26, I took pain medication and by the next day, July 27, I felt much better.
I was able to eat normally and brush my teeth without feeling any pain from the injection site.
However, I noticed a swollen area in my cheek where it connects to my mandible, and pressing on it causes excruciating pain (I'm not quite sure where it is; it doesn't feel like the gums but rather a deeper connection between the cheek and gums?).
If I remember correctly, this is the area that was extremely painful during the anesthetic injection.
Is this situation normal? I have received local anesthesia several times for dental work, but this is the first time I have experienced such pain and swelling the next day.
Is it possible that the anesthetic was injected incorrectly? (The entire process of anesthesia and filling was performed by a resident, while the attending physician only briefly checked on the filling.) Additionally, the doctor mentioned that the cavity was quite deep and close to the nerve, so I was advised to monitor for any swelling or pus formation in the tooth.
I would like to ask: could the swelling and pain I mentioned earlier be unrelated to the anesthetic and simply due to nerve inflammation or an abscess? (However, the swollen area seems to be somewhat distant from the decayed molar, and I feel the location is not quite right.
Furthermore, I have no idea what nerve inflammation or an abscess should look like.) I would appreciate hearing your professional opinion.
Thank you very much.

Hello: It is possible that the discomfort is related to the lower posterior teeth area, where a mandibular nerve block may sometimes be performed.
The injection site is indeed close to the area you described.
If the discomfort persists, it is advisable to return for a follow-up, especially if you have cardiovascular conditions (such as hypertension or arrhythmias), as it is important to monitor for severe headaches.
On the other hand, dental pulp pain can also be quite severe; however, pulp pain typically presents as intermittent episodes rather than continuous pain, and it can usually be managed with over-the-counter non-steroidal anti-inflammatory drugs.
If you are being treated at a medical center, it is recommended to follow up with the dental or oral surgery department and consider a referral or consultation with a neurologist or other relevant specialties for ongoing monitoring.

More Info

After undergoing dental procedures such as root canal therapy or tooth extraction, it is common to experience pain, swelling, and discomfort. Understanding the reasons behind these symptoms and how to manage them can significantly improve your recovery experience.

Pain and Discomfort After Dental Procedures
1. Anesthesia Pain: The pain you experienced during the injection of anesthesia can sometimes occur if the needle inadvertently touches a nerve or if the anesthetic solution is injected too quickly. This can lead to a sharp, intense pain that is different from the typical discomfort associated with the procedure itself. While it is not common, it can happen, especially in sensitive areas of the mouth.

2. Post-Operative Pain: After dental work, especially procedures like root canals or extractions, it is normal to experience some level of pain as the anesthesia wears off. This pain can be due to inflammation in the tissues surrounding the treated area, as well as the body's natural healing response. Typically, this pain should gradually decrease over a few days.

3. Swelling: Swelling is another common post-operative symptom. It can occur due to the body's inflammatory response to the trauma of the procedure. If you notice swelling in the area where the anesthesia was administered, it could be related to the injection itself or the procedure performed.

Management of Pain and Swelling
1. Medications: Over-the-counter pain relievers such as ibuprofen or acetaminophen can help manage post-operative pain. If the pain is severe, your dentist may prescribe stronger pain medication. It is essential to follow the prescribed dosage and schedule to ensure effective pain management.

2. Cold Compress: Applying a cold compress to the outside of your cheek can help reduce swelling and numb the area, providing relief from pain. This is particularly effective within the first 24 hours after the procedure.

3. Warm Compress: After the initial swelling has decreased, switching to a warm compress can promote blood flow to the area and aid in healing.

4. Rest and Hydration: Ensure you get plenty of rest and stay hydrated. This can help your body recover more efficiently.

When to Seek Further Help
If you notice persistent swelling, severe pain that does not improve with medication, or if you develop a fever, it is crucial to contact your dentist. These could be signs of an infection or other complications that may require additional treatment.

Understanding Nerve Inflammation and Abscesses
Regarding your concerns about nerve inflammation or the possibility of an abscess, it is essential to monitor your symptoms closely. Nerve inflammation can occur if the dental procedure was close to the nerve, leading to pain that may radiate to other areas. An abscess, on the other hand, typically presents with localized swelling, pain, and sometimes fever. If you notice a pus-filled bump or increased pain, it is vital to seek dental care promptly.

Conclusion
In summary, experiencing pain and swelling after dental procedures is common and can be managed effectively with proper care. Understanding the nature of your symptoms and when to seek help can significantly enhance your recovery experience. Always communicate openly with your dental care provider about your symptoms and any concerns you may have, as they can provide tailored advice and treatment options based on your specific situation.
