Is It Normal to Feel Pain After Dental Anesthesia? Insights and Tips - Dentistry

Share to:

The area where the dental anesthesia was administered still experiences pain two days later?


During a dental filling procedure, the dentist administered several injections of anesthesia in the upper jaw due to the depth of the cavity.
After the anesthesia wore off, there was no pain in the tooth, but there seems to be some discomfort around the area where the anesthesia was injected.
There is a sensation of pressure or pain when the tongue exerts force or when food presses against it.
It has been two days since the procedure.
Is this normal? There are no noticeable abnormalities in appearance.

Hello: There may be a skin break at the injection site.
It is recommended to apply a soothing ointment and observe for 3 to 5 days.
If discomfort persists, please return for a follow-up appointment as soon as possible.

More Info


Experiencing pain after dental anesthesia, especially following procedures like fillings or root canals, is not uncommon. The discomfort you are feeling in the area surrounding the injection site, as well as in the upper jaw, can be attributed to several factors related to the dental procedure and the anesthesia itself.

Firstly, it's important to understand that dental anesthesia works by blocking nerve signals in the area where it is administered. While the anesthesia effectively numbs the targeted tooth and surrounding tissues during the procedure, once it wears off, it can leave behind some residual discomfort. This discomfort can manifest as soreness or tenderness in the muscles and tissues that were affected by the injection. The injection itself can sometimes cause localized inflammation, which may contribute to the pain you are experiencing.

In your case, since you mentioned that the pain is not in the tooth itself but rather in the area around the injection site, this is likely a normal response. The upper jaw, particularly the area where the anesthetic was injected, can be sensitive for a few days post-procedure. This sensitivity can be exacerbated by activities such as chewing or applying pressure with your tongue, which can lead to a sensation of swelling or discomfort.

Here are some insights and tips to help manage this discomfort:
1. Pain Management: Over-the-counter pain relievers such as ibuprofen or acetaminophen can be effective in managing post-anesthesia discomfort. Make sure to follow the recommended dosages and consult your dentist if you have any concerns.

2. Cold Compress: Applying a cold compress to the outside of your cheek near the injection site can help reduce swelling and numb the area, providing relief from pain.

3. Soft Diet: For the first few days after your dental procedure, consider sticking to a soft diet to minimize pressure on the affected area. Foods that are easy to chew and swallow can help prevent aggravating the pain.

4. Avoid Irritants: Try to avoid very hot or cold foods and beverages, as they can exacerbate sensitivity in the area. Additionally, refrain from using tobacco products, as they can delay healing.

5. Follow-Up: If the pain persists beyond a few days or worsens, it is crucial to follow up with your dentist. They can assess whether there is an underlying issue, such as an infection or an adverse reaction to the anesthesia.

6. Communication with Your Dentist: Always keep an open line of communication with your dental care provider. If you have concerns about the pain or any other symptoms, do not hesitate to reach out for advice or a follow-up appointment.

In summary, while it is normal to experience some discomfort after dental anesthesia, especially in the area surrounding the injection site, it is essential to monitor your symptoms. If the pain continues or becomes more severe, consulting your dentist is the best course of action to ensure there are no complications. Remember that everyone's pain tolerance and healing process are different, so what is normal for one person may not be the same for another.
