A newly placed cavity filling shouldn't hurt, but if yours does, several factors could be at play. Understanding the potential causes can help you address the issue and alleviate discomfort. This guide explores the common reasons for post-filling pain and what you can do about it.
Is the Pain Immediate or Delayed?
The timing of your pain can offer clues about its source. Immediate pain suggests a problem during or immediately after the procedure, while delayed pain might indicate a different issue. Let's explore both.
Immediate Pain After a Filling:
- Irritation of the Nerve: Even with local anesthetic, the drilling and filling process can sometimes irritate the tooth's nerve. This usually subsides within a few days as the irritation heals.
- High Filling: If the filling material is placed too high, it can create pressure on your teeth when you bite down, causing pain.
- Improper Bite: A misaligned bite, where your teeth don't meet correctly, can also lead to pain after a filling. This often causes pain when chewing or biting.
- Infection: In rare cases, an infection could develop during the procedure. This is usually accompanied by swelling, redness, and increased pain.
Delayed Pain After a Filling:
- Sensitivity to Temperature: This is a common side effect after a filling and usually resolves on its own within a few weeks. The filling material might not be completely sealed, allowing sensitivity to cold or hot temperatures.
- Fractured Tooth: The tooth might have been weakened prior to the filling, and the filling process might have inadvertently caused a fracture. This often manifests as sharp, shooting pain.
- Poorly Placed Filling: A filling that doesn't completely seal the cavity can allow bacteria to enter, leading to infection and pain.
- Sinus Infection: Sometimes, upper molar fillings can cause pain referred to the sinuses, particularly if a sinus infection is already present. This pain is often more of a dull ache in the sinus area.
What Should I Do If My Filling Hurts?
If the pain is mild and subsides after a few days, you might not need to take any action beyond over-the-counter pain relief like ibuprofen. However, if the pain is severe, persistent, or accompanied by other symptoms like swelling or fever, you should contact your dentist immediately.
How Long Does Post-Filling Pain Typically Last?
Most post-filling discomfort is temporary and resolves within a few days to a couple of weeks. However, if the pain persists for longer than this, or if it worsens, it's crucial to consult your dentist.
Can a Filling Cause Long-Term Pain?
While most fillings don't cause long-term pain, there are exceptions. A poorly placed filling, an undetected crack in the tooth, or an infection can lead to persistent discomfort. In such cases, your dentist might need to remove and replace the filling or address the underlying issue.
Is It Normal to Feel Pressure After a Filling?
Some pressure or slight discomfort is common immediately after a filling, especially if the dentist had to remove a significant amount of decayed tooth structure. This is usually temporary and resolves as the area heals. However, intense or prolonged pressure should be reported to your dentist.
