Risks and Considerations of a Dental Filling: What You Need to Know

Dental fillings are a routine and effective way to treat cavities and restore a tooth's function. While they are generally safe, it's important to be aware of the potential, albeit rare, risks and side effects.

One of the most common issues is temporary tooth sensitivity. After the filling is placed, the tooth may be sensitive to pressure, air, or hot and cold temperatures. This is typically a normal reaction as the tooth adjusts to the new filling and should subside within a few weeks. If the sensitivity is severe, persistent, or accompanied by a throbbing toothache, it could indicate that the decay was deep and has irritated the tooth's pulp, possibly requiring a root canal.

Another concern can be a misaligned bite. If the filling is too high, it can interfere with your natural bite, causing pain when you chew. Your dentist can easily correct this by reshaping the filling.

Allergic reactions to the filling material, while extremely rare, are also a possibility. Symptoms may include a rash or itching. If you have known allergies to certain metals, it is crucial to inform your dentist before the procedure, as amalgam (silver) fillings contain mercury, silver, tin, and copper, and composite (white) fillings contain plastic and glass.

Finally, fillings are not permanent. Over time, due to daily wear and tear from chewing, they can wear down, chip, or crack. This can create a small gap between the filling and the tooth, allowing bacteria to seep in and cause new decay. Regular dental check-ups are essential to monitor your fillings and ensure they remain in good condition to protect your tooth for years to come.
