Tooth Sensitivity and Dental Onlays: A Complete Guide

December 24, 2025

Onlays are a durable yet cosmetic option for restoring a damaged or decayed tooth. Restorations that are crafted to your specifications can improve the strength and appearance of a tooth while preserving as much of the natural structure as possible. However, one of the first questions that dental patients ask after receiving onlays is whether their teeth will feel sensitive. If you’re considering onlays, understanding why there may be some sensitivity and how to manage it will be helpful. 

Learning About Dental Onlays Sensitivity

Dental onlays are commonly used to treat teeth that have experienced significant decay or damage, but still have enough healthy tooth structure to retain a restoration. Restorations made with porcelain resin or gold will give your teeth a natural, durable finish. Post-procedure tooth sensitivity is common, though onlays are generally well-tolerated by those who receive dental onlays.  Tooth sensitivity is usually temporary, although it can vary based on the extent of the damage and how well the onlay fits the tooth.

Dental onlays in Portage Park, IL, are specifically designed to restore the damaged tooth. Tooth preparation can still expose dentin, making the tooth sensitive. Dentin is the sensitive layer beneath the enamel, and exposure to hot, cold, or sweet foods or drinks can cause discomfort when eating or drinking.

What Causes Tooth Sensitivity After an Onlay?

The following factors are most commonly associated with tooth sensitivity after you have received Dental onlays in Portage Park, IL:

  • Exposure of Dentin: During preparation, your dentist may remove a small amount of enamel, exposing the dentin, which is sensitive to temperature changes and pressure.
  • Nerve Sensitivity: If the tooth receiving the onlay has larger cavities, the tooth’s nerves will be more sensitive to the onlay procedure.
  • Improper Bite: If the onlay does not fit properly or the bite doesn’t line up correctly, it can create pressure on the tooth, leading to pain.

How to Manage Sensitivity After Onlay Placement

While sensitivity is common, there are steps you can take to minimize discomfort:

  • Avoid Extreme Temperatures: Avoid hot, cold, and acidic foods or drinks for the first couple of days after the onlay application. Extreme heat, cold, and acidic foods and beverages can make your teeth more sensitive.
  • Use Toothpaste for Sensitive Teeth: Toothpaste specifically formulated for sensitive teeth will soothe your nerves and reduce sensitivity.
  • Contact Your Dentist: If the sensitivity doesn’t improve after a few weeks, it’s a good idea to schedule a check-up with your dentist. They may need to make adjustments to the onlay or check for other issues.

When Should You Visit Your Dentist and What Should You Expect?

If you have ongoing discomfort for several weeks or beyond your normal sensitivity, you should make an appointment with your dentist as soon as possible. Long-term pain may indicate that adjustments are needed to your onlay, or that it needs to be replaced altogether. Visiting your dentist ensures that your onlays are functioning efficiently and that your oral health is being taken care of.
