Dental appointments require replacing old fillings.
Composite dental fillings, a popular choice for restoring damaged teeth, typically last between 5 to 10 years, with the possibility of exceeding 10 years with proper care [1][3][4][5]. However, it's essential to understand that these fillings do not last a lifetime.
The lifespan of a filling depends on several key factors. Oral hygiene, regular brushing, and flossing help prevent decay around the filling, extending its durability [3][5]. High bite forces, grinding or clenching teeth (bruxism), and chewing hard foods can wear down or damage fillings faster [5]. The location of the filling, whether on molars or in areas subject to heavy chewing, also affects its lifespan [4].
The quality of the material and the placement technique are crucial factors as well. Modern composite materials and expert placement can improve longevity [4]. Regular dental check-ups are essential for early detection of wear, cracks, or leaks, helping maintain the filling’s integrity [3].
A filling's appearance can be intact on the outside, but it may no longer be functioning properly on the inside. Many factors affect the lifespan of a filling, including the quality of the material, placement technique, tooth's load, hygiene, bite patterns, and habits [6]. Only a dentist can detect hidden issues with fillings that require replacement, such as changes visible only on X-ray or CT scan, or secondary caries without pain or pulp inflammation [7].
If a part of a filling has chipped, seeing a dentist is a good idea [8]. Delaying replacement of a filling can lead to pulpitis (nerve inflammation) [9]. Nut lovers may find their fillings chip earlier due to habits [10]. The average lifespan of a composite filling is around 3-5 years [2].
It's also advisable to see a dentist if the edges of the filling have darkened or it has become rough, detached, etc. Delaying replacement of a filling can lead to deep caries [7]. A microscopic gap can form between a filling and the tooth over time [6]. Increased sensitivity to hot, cold, or sweet foods can signal that a filling needs to be replaced [9]. Pain when biting down can also indicate the need for a filling replacement [9].
However, if there are no symptoms, it's still recommended to have regular dental check-ups to monitor the condition of fillings. Regular dental check-ups are important for detecting these hidden issues and maintaining good oral health [11].
- Maintaining good oral hygiene, such as regular brushing and flossing, can help prolong the lifespan of fillings by preventing decay around them and extending their durability.
- Undergoing regular dental check-ups is essential for early detection of wear, cracks, or leaks in fillings, which helps in maintaining the filling's integrity and preventing further damage.
