Composite Fillings and Tooth Sensitivity

Tooth sensitivity is a common experience after getting a composite filling. While it’s usually temporary, it can cause some initial discomfort—especially when eating or drinking hot, cold, or sweet foods.

At Sweet Water Dentistry, we aim to prepare you for what to expect and offer solutions if sensitivity lasts longer than it should. Here’s everything you need to know about composite fillings and post-treatment sensitivity.

Why Does Sensitivity Happen?

After a filling, your tooth may feel more sensitive due to:

• Nerve irritation during the drilling process
• The bonding materials used during placement
• Biting pressure on a newly restored tooth
• Slight inflammation of the tooth pulp

These effects are common, especially for deeper fillings or when decay was close to the nerve.

How Long Does It Last?

For most patients, mild sensitivity lasts anywhere from a few days to two weeks. It typically resolves on its own as your tooth adjusts to the new filling.

If sensitivity persists beyond three weeks or worsens over time, it’s important to schedule a follow-up with Dr. Greer for evaluation.

Common Triggers for Sensitivity

• Cold drinks or air
• Hot foods or beverages
• Sweet foods
• Biting or chewing
• Brushing near the affected tooth

Let us know what type of sensitivity you’re experiencing, as this helps us identify the cause and solution.

Tips to Manage Sensitivity

If you’re feeling discomfort after your filling, try these steps:

• Use a toothpaste designed for sensitive teeth
• Avoid extreme temperatures in food and drinks
• Chew on the opposite side of your mouth
• Avoid very sweet or acidic foods for a few days
• Take over-the-counter pain relievers as directed

At Sweet Water Dentistry, we may also recommend a fluoride varnish or desensitizing treatment in-office.

When to Call the Dentist

It’s time to give us a call if:

• Pain is sharp or worsening
• You feel sensitivity when biting
• Your bite feels uneven
• The sensitivity lasts more than 3 weeks

In rare cases, continued discomfort could signal an issue such as a high filling, microleakage, or pulpitis (inflammation inside the tooth). Early evaluation can prevent further problems.

Can Composite Fillings Cause More Sensitivity Than Other Types?

Composite fillings do occasionally cause more short-term sensitivity than amalgam due to the bonding process. However, the benefits—like tooth-colored aesthetics and conservative placement—typically outweigh this temporary drawback.

Once your tooth has fully adjusted, it should feel and function just like your natural tooth.
