Swelling and Pain in the Upper Left Gum: Possible Causes and Solutions

Pain and swelling on the inner side of the upper left jaw?

Hello, doctor.
Two days ago, I had a filling done on my upper left second to last tooth.
During the procedure, anesthesia was administered in three areas.
The next day, I noticed swelling in the gum tissue on the inner side of my upper left last tooth.
It doesn't hurt spontaneously, but I feel pain when pressure is applied or when my tongue touches it.
I recall that this was one of the areas where anesthesia was given.
What could this symptom indicate? Thank you.

The above situation may be related to the site of anesthesia injection.
It is recommended to return for a follow-up appointment with a dentist to check for possible periodontal infection or localized swelling caused by the anesthesia.

More Info

Swelling and pain in the upper left gum can be concerning, especially following a dental procedure like filling a tooth. Based on your description, it seems that the swelling and pain are localized around the area where the dental work was performed, specifically near the last molar on the upper left side. Here are some possible causes and solutions for your symptoms.

Possible Causes:
1. Post-Operative Inflammation: After dental procedures, it is common to experience some degree of inflammation in the surrounding tissues. This can be due to the trauma of the procedure itself, especially if multiple injections were administered for anesthesia. The body’s natural response to trauma is to send more blood to the area, which can cause swelling and tenderness.

2. Infection: If the swelling persists or worsens, it could indicate an infection, such as a dental abscess. This is particularly possible if bacteria entered the gum tissue during the procedure. Symptoms of infection may include increased pain, swelling, redness, and possibly fever.

3. Allergic Reaction: Although rare, some individuals may have an allergic reaction to the anesthetic used during the procedure. This could lead to localized swelling and discomfort.

4. Trauma to the Gum Tissue: The process of filling a tooth can sometimes inadvertently cause trauma to the surrounding gum tissue, leading to localized pain and swelling.

5. Residual Anesthetic Effects: The area where the anesthesia was administered may still be experiencing residual effects, which can sometimes lead to temporary swelling and sensitivity.

Recommended Solutions:
1. Saltwater Rinse: Rinsing your mouth gently with warm salt water can help reduce inflammation and promote healing. It also has antibacterial properties that can help prevent infection.

2. Cold Compress: Applying a cold compress to the outside of your cheek near the affected area can help reduce swelling and numb the pain. Make sure to wrap the ice pack in a cloth to avoid direct contact with the skin.

3. Over-the-Counter Pain Relief: Non-steroidal anti-inflammatory drugs (NSAIDs) like ibuprofen can help alleviate pain and reduce inflammation. Be sure to follow the dosage instructions on the package.

4. Avoid Irritating Foods: For the time being, avoid hard, crunchy, or spicy foods that could irritate the swollen gum area. Stick to soft foods that are easier to chew.

5. Monitor Symptoms: Keep an eye on your symptoms. If the swelling does not decrease within a few days, or if you develop additional symptoms such as fever, increased pain, or pus discharge, it is important to contact your dentist or healthcare provider.

6. Follow-Up Appointment: If the pain and swelling persist, it is advisable to schedule a follow-up appointment with your dentist. They can assess the area for any signs of infection or other complications and provide appropriate treatment.

In conclusion, while some swelling and discomfort can be expected after dental work, persistent or worsening symptoms should not be ignored. It’s essential to monitor your condition and seek professional advice if necessary. Your oral health is crucial, and timely intervention can prevent further complications.
