How Long Do Dental Fillings Last? What Factors Affect Their Lifespan?

If you’ve ever had a cavity treated, chances are you’ve received a dental filling. Fillings are a common restorative treatment that helps protect your tooth from further decay while restoring its strength and function. But how long can you expect a filling to last? And what affects its durability? 

At Brightway Dental in Lincoln, Nebraska, we want to make sure our patients understand every aspect of their dental care, including how to make restorations like fillings last as long as possible. In this blog, we’ll cover the average lifespan of dental fillings and what can influence their longevity. 

How Long Do Dental Fillings Last? 

While dental fillings are not meant to last forever, they can provide many years of protection when properly placed and maintained. On average, dental fillings can last anywhere from 2 to 15 years and sometimes even longer. 

However, every patient is different. Some people may need a filling replaced sooner due to wear and tear, while others may enjoy decades without issues. The condition of the tooth, lifestyle habits, and oral hygiene all play a major role in how long a filling will last. 

Factors That Affect the Lifespan of Fillings 

There are several factors that determine how long a dental filling will last over time. Here are the most important ones to be aware of: 

1. Oral Hygiene Habits 

Good brushing and flossing habits are key to prolonging the life of your fillings. When plaque and bacteria are kept under control, you reduce the risk of decay forming around or underneath the filling. Regular dental cleanings and check-ups also help detect early signs of damage. 

2. Size and Location of the Filling 

Fillings that cover a larger area of the tooth are generally more vulnerable to stress. Likewise, fillings on back teeth may wear out faster due to the heavier pressure of chewing and grinding, and fillings on the incisal edges of front teeth are prone to more frequent chipping due to their location. This makes routine dental exams important, so your dentist can monitor for signs of wear. 

3. Bite Pressure and Grinding 

If you clench or grind your teeth, especially at night, it can significantly reduce the lifespan of your fillings. This condition, known as bruxism, puts extra pressure on your teeth and restorations. If this is something you struggle with, we may recommend a custom night guard to protect your dental work. 

4. Dietary Habits 

What you eat and drink can also impact your fillings. Sticky or hard foods can cause a filling to loosen or chip, while acidic beverages and sugary snacks can erode the surrounding tooth structure. A tooth-friendly diet low in sugar and high in nutrients supports both natural teeth and restorations. 

5. Time and Natural Wear

Even with excellent care, dental fillings will naturally wear down over time. Your mouth is a dynamic environment, and daily use puts stress on all dental work. Eventually, every filling will need to be repaired or replaced to maintain a healthy, functional smile. 

Signs That a Filling May Need to Be Replaced 

It’s important to recognize when a filling is no longer doing its job. Here are a few signs that it might be time to replace one: 

• Increased sensitivity to hot, cold, or sweet foods 
• A visible crack or chip in the filling 
• Feeling that the filling is loose or missing 
• Food frequently getting stuck near the filled tooth 
• New decay forming around the edges of the filling 

If you notice any of these symptoms, don’t wait, schedule an appointment with Brightway Dental. We’ll examine the filling, assess the surrounding tooth, and determine the best course of action. 

How to Help Your Fillings Last Longer 

While no filling lasts forever, there are several ways to help extend its lifespan: 

• Brush twice a day and floss daily 
• Limit sugary and acidic foods and beverages 
• Visit your dentist every 6 months for cleanings and exams 
• Avoid chewing on hard objects like ice or pens 
• Use a night guard if you grind or clench your teeth 

At Brightway Dental, our goal is to help your dental work last as long as possible through preventive care and ongoing support.
