Having a dental filling is a common and effective way to restore a decayed tooth. However, many patients are surprised when they experience some discomfort or sensitivity afterwards. If you’ve recently had a filling and now have a toothache, you might be wondering: is this normal?
Mild toothache after a filling is usually normal and part of the healing process. You may feel sensitivity to temperature or pressure for a few days. However, if the pain worsens, persists beyond two weeks, or becomes severe, it’s important to contact your dentist for a professional review.
At Purley Dental Care, we believe that understanding your dental health empowers you to feel more confident and at ease.

Why You Might Feel a Toothache After a Filling
It’s quite common to feel some discomfort following a filling. Here are the most frequent reasons:
- Nerve Irritation: When decay is removed, it can disturb the tooth’s nerve, especially if the cavity was deep or close to the pulp. This can result in temporary sensitivity or a dull ache.
- Bite Misalignment: Even a tiny difference in how your teeth meet can create significant pressure on the filled tooth. If the filling is slightly too high, you may feel pain when biting down or chewing on that side.
- Inflammation and Trauma: The process of drilling and placing a filling can create trauma to the soft tissues or periodontal ligament around the tooth, leading to inflammation and tenderness for a few days.
- Material Sensitivity: Some people react to the materials used in fillings, especially metal-based amalgam or even certain composite resins. This can cause temporary hypersensitivity.
- Multiple Fillings or Deeper Treatment: If you’ve had several fillings in one visit or a deep restoration, your teeth and surrounding structures may feel more sensitive than usual.
The good news? Most of these symptoms are temporary and manageable with proper care and monitoring.
What’s Considered ‘Normal’ Pain After a Filling?
Mild discomfort after a filling is part of the tooth’s healing process. In most cases, this is no cause for concern and will settle on its own.
Here’s what you can expect:
- Temperature Sensitivity: You might feel a brief, sharp sensation when drinking hot or cold beverages. This usually lessens over several days.
- Mild Soreness When Biting or Chewing: Some tenderness when chewing is common, especially within the first 24 to 72 hours.
- Occasional Twinges or Pulses: Sharp but short-lived twinges are often part of nerve adjustment and should reduce over time.
- Duration: Normal healing-related pain or sensitivity typically improves within a few days to no more than two weeks.
Pain that fades or improves day by day is generally not a red flag, especially if it’s manageable without pain relief. If the pain stays the same or worsens, it’s worth a second look.
When Toothache After a Filling Might Be a Concern
While post-filling sensitivity is common, ongoing or escalating pain may indicate an underlying issue. Watch for these warning signs:
- Persistent or Worsening Pain: If your pain is not improving or feels more intense after the first few days, it may suggest nerve inflammation or pulpitis.
- Sharp Pain When Biting or Chewing: This could mean the filling is sitting too high and putting extra pressure on the tooth.
- Throbbing or Spontaneous Pain: A pulsing sensation or pain that comes on without biting or chewing may indicate nerve damage or infection.
- Visible Cracks or Filling Damage: If you notice sharp edges, roughness, or part of the filling feels loose, it might have chipped or come away slightly.
- Swelling, Bad Taste or Fever: These signs suggest an underlying infection, possibly requiring root canal treatment or antibiotics.
If you notice any of the above, contact Purley Dental Care immediately. Early diagnosis helps preserve the tooth and avoid more invasive treatments.
Can You Prevent Toothache After a Filling?
Yes, there are several steps patients and dentists can take to minimise discomfort after treatment:
- Early Treatment: Addressing cavities while they’re small reduces the chance of post-treatment sensitivity.
- Accurate Bite Checks: Ensuring the filling aligns with your natural bite is essential. At Purley Dental Care, we always take time to check and refine your bite.
- Avoid Hard Foods Post-Treatment: Give your tooth time to settle. Stick to soft foods for the first 24 hours if you’ve had a large or deep filling.
- Use a Sensitive Toothpaste: A desensitising toothpaste can help reduce discomfort while your tooth adjusts.
- Avoid Extreme Temperatures: Steer clear of very hot or cold foods for the first few days to prevent triggering sensitivity.
If you follow these tips and still feel pain beyond a few days, it may be time for a review.
What to Expect at a Review Appointment
If your toothache continues, we may recommend a simple review to ensure everything is healing as expected. During your visit, we will:
- Listen to Your Symptoms: We’ll ask how the discomfort started and whether it’s changed or worsened.
- Examine the Filling: We’ll check for high spots, cracks, gaps, or material wear.
- Assess the Surrounding Area: Sometimes, the discomfort can stem from neighbouring teeth or gums.
- Perform Bite Adjustments if Needed: Often, a slight polish or reshaping solves bite-related pain instantly.
- Recommend Further Care: If deeper issues are present, we may suggest further x-rays or treatment options such as a protective dressing or root canal therapy.
Our focus is always to offer gentle, effective solutions with the least disruption to your daily life.

FAQs
How long should a filling be sensitive?
Sensitivity can last for a few days to around two weeks. This varies depending on the size and depth of the filling. If the discomfort lasts beyond that, it could indicate bite issues or nerve involvement.
Why does my tooth hurt when I bite after a filling?
A likely cause is that the filling is slightly too high, causing excess pressure when biting down. A quick adjustment by your dentist can usually resolve this.
Is it normal to have a sharp pain after filling?
Yes, mild sharp twinges are common and should fade over time. However, sharp pain that doesn’t improve or gets worse could signal deeper issues such as pulpitis or a cracked tooth.
Can a filling cause nerve damage?
A deep cavity close to the nerve can lead to pulpitis, where the nerve becomes inflamed. While not permanent damage, it may require root canal treatment if symptoms persist.
What should I do if my filling still hurts after a week?
If you’re still experiencing pain or increasing sensitivity after seven days, it’s best to book a review. The solution may be as simple as a bite adjustment or more complex if deeper tissues are involved.
