Dental fillings are one of the most common dental treatments, used to repair cavities and restore the function of your teeth. Over time, you may wonder how long your fillings will last and when they need to be replaced. As a trusted dentist near me in Woodland Hills, CA, I’m here to help you understand the lifespan of dental fillings and the signs that indicate when it’s time for a replacement.
What Are Dental Fillings Made Of?
Dental fillings are made from a variety of materials, each with its own characteristics in terms of durability, appearance, and cost. The most common materials used for fillings include:
- Amalgam (Silver Fillings): A durable, silver-colored material made from a mixture of metals such as silver, mercury, tin, and copper.
- Composite Resin (Tooth-Colored Fillings): A more aesthetic option, composite resin fillings are made from a mixture of plastic and fine glass particles that can match the color of your natural teeth.
- Gold Fillings: Gold is a strong, long-lasting material often used for fillings in the back teeth.
- Ceramic Fillings: These fillings are made from porcelain and are known for their strength and natural appearance, often used for visible teeth.
The lifespan of your filling depends on the material used, as well as factors like your oral hygiene habits, diet, and the location of the filling in your mouth.
How Long Do Fillings Last?
The longevity of a dental filling can vary, but here’s a general guideline for each type of filling:
- Amalgam Fillings: These fillings are highly durable and can last 10-15 years or more with proper care.
- Composite Resin Fillings: While composite fillings can look more natural, they tend to wear out faster than amalgam. They typically last 5-7 years, but can be shorter depending on location and usage.
- Gold Fillings: Gold is one of the longest-lasting filling materials, with an average lifespan of 15-20 years or longer if well cared for.
- Ceramic Fillings: Porcelain fillings can last 10-15 years or more, and they are highly resistant to wear and staining.
Factors That Affect the Lifespan of Fillings
Several factors can affect how long your dental fillings last, including:
1. Location of the Filling
Fillings in areas that experience a lot of pressure, such as the back teeth (molars) used for chewing, may wear out faster. Fillings in areas with less pressure, such as the front teeth, tend to last longer.
2. Oral Hygiene Habits
Good oral hygiene is key to extending the life of your fillings. Brushing twice a day, flossing regularly, and visiting your dentist for routine checkups can help prevent cavities around the filling and reduce wear and tear.
3. Diet and Habits
A diet high in sugar and acidic foods can contribute to the deterioration of fillings. Additionally, habits like teeth grinding (bruxism) or chewing on hard objects can cause fillings to wear out more quickly. If you have bruxism, your dentist may recommend a night guard to protect your fillings and teeth.
4. Size of the Filling
Larger fillings are more susceptible to cracks and damage over time, especially if the tooth is already weakened by significant decay. Small fillings are typically more stable and can last longer.
Signs That Your Filling Needs to Be Replaced
Even the best fillings wear out eventually. It’s important to watch for signs that indicate it might be time for a replacement. Here are some common signs that your filling may need attention:
1. Pain or Sensitivity
If you feel pain or sensitivity when chewing, drinking hot or cold beverages, or biting down, it could indicate that your filling has become loose or cracked. If the tooth underneath the filling is exposed, it can lead to sensitivity and discomfort.
2. Visible Cracks or Chips
If your filling has visible cracks, chips, or holes, it may no longer be providing the protection your tooth needs. This can allow bacteria to enter the tooth and lead to further decay.
3. Discoloration Around the Filling
If you notice that the area around your filling is darkening or staining, it may be a sign that the filling is deteriorating, or that decay is occurring around the edges.
4. Feeling of Roughness or Edges
If your filling feels rough, or if there are sharp edges or ridges, it may need to be smoothed or replaced. This is especially important for preventing irritation to the inside of your mouth.
What Happens During a Filling Replacement Procedure?
Replacing a filling is a relatively simple procedure. Here’s what you can expect when you need a new filling:
- Examination: Your dentist will examine the tooth and determine the condition of the existing filling. If the tooth has further decay, they may need to clean it out before placing a new filling.
- Preparation: The old filling will be removed, and the tooth will be cleaned and prepared for the new filling.
- Filling Placement: The new filling will be placed, shaped, and hardened. The process will depend on the material used, whether it’s composite resin, amalgam, or another type.
- Final Adjustments: Once the filling is in place, your dentist will check your bite to ensure it feels comfortable and that there are no issues with how the filling fits.
How to Care for Your Fillings
Taking good care of your fillings can help extend their lifespan. Here are some tips for maintaining your fillings:
- Brush and floss regularly: Keeping your teeth clean helps prevent decay from developing around the filling.
- Visit your dentist regularly: Routine checkups allow your dentist to monitor the condition of your fillings and catch any potential problems early.
- Avoid hard foods: Try to avoid chewing on ice, hard candies, or other foods that can damage your fillings.
- Wear a mouthguard: If you grind your teeth at night, consider wearing a mouthguard to protect your fillings from excessive pressure.
