Dental fillings are a common solution for treating cavities and restoring damaged teeth, but like anything in life, they don’t last forever. Over time, fillings can wear down or become damaged, requiring replacement. If you’ve had a filling for years, you may wonder how long it will last and when you should consider having it replaced. At Medivance Dental, we specialize in dental fillings in Perth and are here to provide you with the information you need to keep your smile healthy and strong. In this blog, we’ll discuss how long dental fillings last and the signs that indicate it’s time to replace them.
How Long Do Fillings Last?
The lifespan of a dental filling depends on several factors, including the type of material used, the size of the filling, and the location of the filling in the mouth. On average, most dental fillings last between 5 to 15 years, but some can last even longer with proper care.
Factors Affecting the Lifespan of Fillings:
- Material Used: Different filling materials have different lifespans. For example:
- Amalgam Fillings (Silver Fillings): These fillings are durable and can last 10 to 15 years or longer, especially for back teeth where strength is needed.
- Composite Fillings (Tooth-Colored Fillings): These are less durable than amalgam fillings but can last around 5 to 10 years. They are often used for fillings in visible areas because they blend in with the natural color of your teeth.
- Ceramic and Porcelain Fillings: These fillings are long-lasting and can last up to 15 years or more, offering durability and a natural appearance.
- Glass Ionomer Fillings: These fillings are more commonly used for smaller cavities or in areas that are less visible. They typically last around 5 to 10 years.
- Size of the Filling: Larger fillings may be more prone to wear and tear and might need to be replaced sooner than smaller ones. Over time, the larger the filling, the more stress it bears, which can shorten its lifespan.
- Location of the Filling: Fillings placed in areas that experience a lot of pressure from chewing, such as molars, may wear down faster than those in areas that are less frequently used, like the front teeth.
Signs You Need a Dental Filling Replacement:
Even the most durable fillings won’t last forever. Here are some common signs that it might be time for a dental filling replacement in Perth:
1. Tooth Sensitivity:
If you experience increased sensitivity to hot, cold, or sweet foods in a tooth that has been filled, it could be a sign that your filling is deteriorating or has come loose. Sensitivity may indicate that the filling is no longer protecting the tooth properly, allowing temperature or pressure to reach the sensitive part of the tooth.
2. Pain or Discomfort When Chewing:
If you feel pain or discomfort when chewing or biting down, it could mean that your filling is cracked, loose, or worn down. A damaged filling may cause irritation or discomfort, especially when it comes in contact with pressure during chewing.
3. Visible Cracks or Chips in the Filling:
If you notice that your filling is cracked, chipped, or missing pieces, it’s time to see a dentist. Cracked fillings can expose the tooth to further decay and increase the risk of infection or damage to the underlying tooth.
4. Discoloration Around the Filling:
If you notice a dark line or discoloration around the edges of the filling, it may indicate that the filling has begun to deteriorate or that decay is developing underneath it. This can be a sign that the filling is no longer properly sealed to the tooth, allowing bacteria to infiltrate the area.
5. Filling Comes Loose or Falls Out:
If a filling comes loose or falls out entirely, it’s essential to see your dentist immediately. A missing or loose filling leaves the tooth vulnerable to further decay and infection. Your dentist will need to replace the filling to restore the tooth’s strength and protect it from damage.
6. Pain in the Surrounding Gums:
If your filling is causing irritation or pain in the gums surrounding the treated tooth, it could be a sign that the filling has become improperly seated, or there’s decay underneath it. Inflamed or painful gums may indicate an issue that requires professional attention.
How a Tooth Specialist Can Help:
A tooth specialist at Medivance Dental can assess the condition of your existing fillings and determine if a replacement is needed. Depending on the situation, your dentist may recommend:
- Replacing the old filling with a new one that better matches the condition of your tooth.
- Upgrading to a more durable material (such as from a composite filling to a porcelain one).
- Providing a crown if the filling needs to cover a more significant portion of the tooth or if the tooth structure is compromised.
How to Prolong the Life of Your Fillings:
While fillings are durable, they require care to ensure they last as long as possible:
- Maintain good oral hygiene: Brush your teeth at least twice a day and floss daily to prevent plaque buildup around fillings.
- Avoid hard foods: Chewing hard foods (like ice or hard candy) can put stress on fillings, leading to cracking or chipping.
- Visit your dentist regularly: Regular dental checkups allow your dentist to monitor the condition of your fillings and address any issues before they become more severe.
Conclusion:
Dental fillings are designed to restore and protect damaged teeth, but they don’t last forever. Over time, fillings can wear down, crack, or even fall out, requiring replacement. If you notice any of the signs listed above, it’s essential to see a tooth specialist for a professional evaluation.
