Experiencing some discomfort after a dental filling is common. A degree of sensitivity following the procedure is often a normal part of the healing process. Understanding typical sensations and knowing when to seek dental advice can help manage expectations.
Expected Post-Filling Sensitivity
After a dental filling, temporary sensitivity in the treated tooth is common. This sensitivity often manifests as a sharp, fleeting pain when exposed to hot or cold temperatures, air, sweet foods, or pressure from biting. This discomfort typically resolves within a few days to a couple of weeks. For most, sensitivity should subside within two to four weeks as the tooth adjusts to the new restoration.
Common Reasons for Discomfort
Receiving a dental filling involves removing decayed material, which can irritate the tooth’s sensitive nerve endings. Drilling generates heat and vibration, potentially causing temporary inflammation of the dental pulp, the innermost part of the tooth containing nerves and blood vessels. When a cavity is deep, the filling material is placed closer to the pulp, leading to heightened sensitivity. The type of filling material also plays a role; metal fillings, for example, conduct temperature changes more readily than composite resins, increasing sensitivity to hot or cold stimuli. A slight change in the bite due to the new filling can also cause discomfort when chewing due to uneven pressure.
When to Contact Your Dentist
While some post-filling sensitivity is expected, certain symptoms indicate a need to contact your dentist.
Severe, throbbing pain that worsens over time instead of improving warrants professional evaluation.
Persistent sensitivity lasting beyond two to four weeks, or interfering with daily activities like eating or speaking.
Swelling around the filled tooth, discharge, fever, or a darkening of the tooth, which could suggest an infection or deeper issue.
Pain when biting down, especially if it feels uneven, or if the filling appears loose or cracked.
An allergic reaction to the filling material, presenting as a rash, itching, or inflammation, which requires immediate attention.
Tips for Managing Post-Filling Pain
For mild discomfort after a filling, several strategies can help manage sensations at home.
Over-the-counter pain relievers, such as ibuprofen or acetaminophen, can effectively alleviate pain and reduce inflammation.
Temporarily avoid foods and drinks with extreme temperatures to minimize sensitivity triggers.
Chew on the opposite side of the mouth to reduce direct pressure on the newly filled tooth, allowing it to heal.
Maintain good oral hygiene, including gentle brushing around the filled tooth and using a desensitizing toothpaste.
Rinse the mouth with warm salt water several times a day to soothe the area and promote healing.
