Getting a cavity filling is an essential step in protecting your teeth from further decay and restoring their strength. But its not uncommon to experience tooth sensitivity after a filling, especially in the first few days. While its generally temporary, knowing how to manage this discomfort can make your recovery smooth and stress-free.
At McLevin Dental in Scarborough, we want every patient to understand what to expect after dental fillings and how to care for their teeth to minimize discomfort.
Why Do Teeth Feel Sensitive After Fillings?
Tooth sensitivity after a filling is normal and typically occurs when:
The nerve inside the tooth reacts to the drilling process.
The tooth adjusts to the filling material.
A filling is slightly high and affects your bite.
Minor inflammation occurs in the pulp (the soft tissue inside the tooth).
Common triggers for post-filling sensitivity include:
Hot or cold food and drinks
Sweet or acidic foods
Pressure from chewing
Air hitting the tooth
How Long Does Sensitivity Last After a Filling?
For most patients, sensitivity lasts a few days to a week. However, in some cases, especially with deeper fillings, mild discomfort can persist for two to four weeks.
If sensitivity worsens or doesnt improve after this time, it may indicate a bite adjustment is needed or that the nerve inside the tooth is irritated.
Practical Tips to Handle Tooth Sensitivity After Fillings
1. Use Toothpaste for Sensitive Teeth
Switch to toothpaste formulated for sensitivity. Brands like Sensodyne or Colgate Sensitive help block sensation from reaching the nerve.
2. Avoid Extreme Temperatures
For a few days, avoid very hot soups, cold drinks, or ice cream. Lukewarm food and beverages are less likely to trigger discomfort.
3. Chew on the Other Side
Give the filled tooth a short break. Chew on the opposite side of your mouth until sensitivity starts to decrease.
4. Avoid Hard, Sticky, or Sugary Foods Temporarily
Crunchy snacks, sticky candies, and very sugary items can aggravate the tooth. Stick to softer, neutral-temperature foods for the first few days.
5. Over-the-Counter Pain Relief
Ibuprofen or acetaminophen can help alleviate soreness if needed. Always follow dosage instructions or consult with McLevin Dental before taking medications.
6. Maintain Excellent Oral Hygiene
Brush twice a day with a soft-bristled toothbrush.
Floss gently to avoid irritating the treated area.
Use fluoride mouthwash to strengthen enamel and reduce sensitivity.
7. Desensitizing Treatments at the Dental Office
If at-home remedies arent enough, McLevin Dental offers professional desensitizing treatments. This may include fluoride varnishes or special bonding agents to coat sensitive areas.
When Is Tooth Sensitivity After Fillings a Concern?
Reach out to McLevin Dental if you notice:
Sensitivity that worsens instead of improving.
A sharp pain when biting or chewing, which might indicate a bite misalignment.
Throbbing pain, swelling, or prolonged discomfort, which could mean the pulp inside the tooth is inflamed or infected.
A cracked filling or discomfort when touching the tooth.
Could the Filling Type Affect Sensitivity?
Yes, the type of filling material can impact sensitivity levels:
Composite (tooth-colored) fillings: More likely to cause temporary temperature sensitivity but are aesthetically pleasing.
Amalgam (silver) fillings: Less temperature-sensitive but may cause minor expansion/contraction with hot or cold foods.
Glass ionomer or ceramic fillings: Typically have lower sensitivity but depend on placement and tooth condition.
Preventing Future Sensitivity and Cavities
Brush and floss daily to avoid new decay around fillings.
Use fluoride toothpaste to strengthen enamel.
Limit sugary and acidic foods that wear down teeth.
Schedule regular dental checkups with McLevin Dental for cleanings and monitoring.
Can a Bite Adjustment Solve the Problem?
Absolutely. One of the most common reasons for post-filling sensitivity is an uneven bite where the new filling is slightly too high. This places extra pressure on the tooth when chewing, causing discomfort.
At McLevin Dental, bite adjustments are quick, painless, and often resolve this issue within minutes. If your filled tooth feels taller or hits first when you bite down, dont hesitate to call.
