Cement fillings, also known as dental amalgam fillings, have been a staple in dentistry for decades. While they've become less prevalent due to the rise of composite resin fillings, many people still have amalgam fillings and wonder about their longevity. The lifespan of a cement filling is influenced by several factors, and understanding these factors is key to maintaining good oral health.
How Long Do Cement Fillings Typically Last?
The lifespan of a cement filling varies greatly depending on several factors, but a reasonable expectation is 10-15 years, although some can last much longer, even 20 years or more. However, this is not a guarantee. Many factors can influence their longevity, leading to earlier replacement.
What Factors Affect the Lifespan of Cement Fillings?
Several factors influence how long a cement filling will last. Understanding these will help you appreciate the variability in lifespan and understand what to expect from your own fillings.
1. Size and Location of the Filling:
Larger fillings, particularly those located on the chewing surfaces of the back teeth, are subjected to more stress and wear, leading to a shorter lifespan. Smaller fillings in less-stressed areas tend to last longer.
2. Oral Hygiene Practices:
Excellent oral hygiene, including regular brushing, flossing, and professional cleanings, is crucial. Poor hygiene can lead to the development of cavities around the filling, necessitating its replacement. Bacteria thrive in areas with poor hygiene, undermining the integrity of the filling.
3. Diet and Habits:
Bruxism (teeth grinding) and the consumption of hard candies or ice can significantly shorten the lifespan of cement fillings. These habits can fracture or chip the filling, requiring repair or replacement. A diet high in sugar also promotes bacterial growth, increasing the risk of decay.
4. The Dentist's Technique:
The quality of the filling placement significantly impacts its durability. A well-placed filling with proper preparation of the tooth structure will last longer than one that is poorly placed.
5. Material Quality:
While less of a concern with properly regulated materials, the quality of the cement filling material itself can affect its longevity. However, this is rarely a primary factor impacting lifespan in modern dentistry.
How Can I Extend the Life of My Cement Fillings?
While you cannot control all factors, you can significantly impact the longevity of your cement fillings through proactive steps:
- Maintain Excellent Oral Hygiene: Brush twice daily with fluoride toothpaste, floss daily, and schedule regular professional cleanings and checkups.
- Avoid Bruxism: If you grind your teeth, discuss options with your dentist, such as a mouthguard.
- Limit Consumption of Hard Foods and Sugary Drinks: Avoid biting on hard objects and reduce your intake of sugary foods and drinks that contribute to dental decay.
- Schedule Regular Dental Checkups: Regular checkups allow your dentist to monitor the condition of your fillings and identify any potential problems early.
Do Cement Fillings Need Replacing Eventually?
Even with excellent care, cement fillings will eventually need replacing. The material degrades over time, and the risk of leakage and secondary decay increases. Regular dental checkups are vital for early detection and prompt action.
What Happens if My Cement Filling Fails?
If a cement filling fails, it might chip, crack, or fall out. You might experience sensitivity to temperature changes, pain when chewing, or notice discoloration around the filling. It's crucial to contact your dentist immediately if you experience any of these symptoms. Ignoring the problem can lead to more extensive damage and more costly treatment in the future.
