Dental fillings are a common procedure to treat cavities and restore tooth structure. After receiving a dental filling, some individuals may experience sensitivity or discomfort in the treated tooth. This post-procedure sensation is a normal part of the healing process as the tooth adjusts to the new filling material.
Reasons for Post-Filling Pain
One common reason for discomfort after a filling is irritation to the tooth’s nerve endings. The process of removing decayed tissue and preparing the tooth for the filling can stimulate these sensitive nerves, leading to heightened sensitivity. This can manifest as a sharp twinge or noticeable discomfort, especially when exposed to hot or cold temperatures, sweet foods, or air.
Another cause of pain can be an uneven bite, often referred to as a “high filling.” If the filling material is not perfectly shaped or polished, it can create a raised spot that interferes with how the teeth come together when biting down. This uneven pressure distribution can lead to discomfort or pain, particularly when chewing. A deep cavity close to the pulp, the tooth’s innermost layer, can cause inflammation (pulpitis), which may require further treatment.
Normal Timeline for Healing
Mild sensitivity or discomfort after a dental filling is a common occurrence. The tooth needs time to heal and adjust to the new filling material, especially if the filling is large or close to the nerve. This temporary sensitivity subsides within a few days to two to four weeks.
During this period, the tooth’s nerves calm down, and the discomfort should gradually decrease each day. Some individuals might experience sensitivity to pressure, air, or hot and cold temperatures, but these sensations resolve on their own. While most sensitivity fades within weeks, in some cases, particularly with deeper cavities, it may take several months to fully resolve.
Ways to Relieve Discomfort
Over-the-counter pain relievers, such as ibuprofen or acetaminophen, can help manage post-filling discomfort and reduce inflammation. Following the dosage instructions carefully is important for effective relief. Applying a cold compress to the outside of the jaw near the affected tooth for 10-15 minutes at a time can also help reduce swelling and numb the area.
Rinsing the mouth with a warm saltwater solution several times a day can promote healing and reduce inflammation. Dissolve about half a teaspoon of salt in eight ounces of warm water and gently swish the solution for 30 seconds before spitting it out. Using a desensitizing toothpaste can also help block pain signals from reaching the nerves inside the tooth. During the initial healing period, avoid hot, cold, sugary, or hard foods, and chew on the opposite side of the mouth to minimize irritation on the newly filled tooth.
When to Seek Further Dental Care
While mild post-filling discomfort is normal, certain symptoms indicate a need for prompt dental attention. If the pain persists for more than two to four weeks, or if it worsens over time, it is important to contact your dentist. Sharp, throbbing, or radiating pain, especially if it interferes with daily activities, also warrants a professional evaluation.
Signs such as swelling, redness around the filled tooth, or a fever could indicate an infection or a deeper underlying issue that requires immediate treatment. If your bite feels uneven or causes significant discomfort when chewing, the filling may need a simple adjustment by your dentist. If you experience extreme sensitivity that is constant or does not subside, or if you suspect an allergic reaction to the filling material, seek dental care.
