Is It Time to Replace Your Old Dental Fillings?
Dental fillings are designed to restore damaged teeth and protect them from further decay, but like all dental work, they do not last forever. Over time, fillings can wear down, crack, loosen, or become discolored, leading to potential problems that may affect your oral health. Knowing when it is time to replace your old fillings is essential to keeping your teeth strong, healthy, and cavity-free.
One of the first signs that a filling may need replacement is sensitivity or discomfort when consuming hot, cold, or sweet foods. This can indicate that the filling is no longer sealing the tooth properly. You may also notice rough edges or cracks, which can trap food particles and bacteria. If the filling becomes loose or falls out, this can expose the tooth to further decay and may require urgent attention.
Another important factor is the age of the filling. While modern fillings are durable, they typically last anywhere from 5 to 15 years, depending on the material and placement. Older silver amalgam fillings may corrode or expand slightly over time, which can cause the tooth to weaken or develop small fractures. White composite fillings, while more aesthetically pleasing, can wear down with years of chewing and grinding.
Regular dental checkups are the best way to monitor the condition of your fillings. Your dentist can detect early signs of wear and provide timely treatment before any complications arise. Replacing old fillings not only protects your oral health but can also enhance the appearance of your smile.
