How Long Do Tooth Fillings Last?

How long do tooth fillings last? This common question is often overlooked once a filling wears out.

While fillings are made to be durable, they won’t last forever. However, with the right maintenance and frequent dentist checkups, they can last for many years.

The Lifespan of Tooth Fillings

A tooth filling’s lifespan is influenced by several factors, including the type of material used, dental habits, and the location of the filling. On average, most fillings can last 5 to 15 years.

However, in some cases, fillings can last much longer if you maintain good oral hygiene and attend regular dental visits.

Different types of fillings have different lifespans:

• Amalgam (Silver) Fillings: These have been used in dentistry for over a century and are known for their strength and durability. Typically, amalgam fillings can last anywhere from 10 to 15 years. However, some patients report that their silver fillings have lasted over 20 years. The downside? Amalgam fillings can stand out due to their metallic colour, making them more noticeable when you smile.
• Composite (Tooth-Colored) Fillings: They are well-liked since they perfectly match the natural hue of your teeth and are constructed of a resin substance. On average, composite fillings last between 5 to 10 years. While they may not be as long-lasting as amalgam, they offer a more aesthetically pleasing option, especially for front teeth.
• Gold Fillings: Known for their durability, they can last up to 20 years or more. They’re less common nowadays due to their cost and the preference for tooth-coloured options, but they remain among the strongest filling materials.
• Ceramic Fillings: Also called porcelain fillings, these are similar to composite fillings in appearance but tend to last longer — around 10 to 15 years. Ceramic fillings are more resistant to staining but can be more expensive than other types.

Factors That Affect the Lifespan of Fillings

It’s important to remember that while the type of filling material plays a significant role in longevity, your dental habits and lifestyle also have a huge impact.

Here are some of the critical factors:

1. Oral Hygiene: Good oral hygiene increases the likelihood of your fillings lasting longer. Frequent dental cleanings, flossing, and brushing can help stop deterioration around your fillings, which could cause them to fail prematurely.
2. Chewing and Biting Habits: If you grind your teeth frequently, a condition known as bruxism or gnawing on hard materials, such as pens or ice, your fillings may wear out faster. This is especially true for composite fillings, which are more prone to wear and tear than metal ones.
3. Location of the Filling: Fillings placed on molars or in areas that endure heavy chewing pressure are likely to wear down faster. Front teeth fillings often last longer since they aren’t exposed to the same pressure level.
4. Regular Dental Checkups: Seeing your dentist regularly allows them to monitor the condition of your fillings and catch any problems early. Over time, fillings can wear down, crack, or even loosen, and your dentist can determine if and when a replacement is necessary.
5. Diet: Consuming many sugar-filled foods and drinks can increase the risk of tooth decay surrounding your fillings, shortening their lifespan. On the other hand, a balanced diet with fewer acidic and sugary foods can help keep your teeth — and your fillings — in better condition for longer.

Signs That Your Filling May Need to Be Replaced

Even though fillings are made to last, they will eventually need to be replaced. Knowing the signs that your filling is failing can prevent more severe issues, like tooth infections or further decay.

• Pain or Sensitivity: It may indicate that your filling is deteriorating or has cracked if you feel pain when you chew or are sensitive to hot, cold, or sweet meals.
• Discolouration: Fillings can become discoloured over time, especially if made of composite material. If your filling starts to look dark or stained, it may need to be replaced.
• Cracks or Chips: If you notice any visible cracks or chips in your filling, it’s time to visit your dentist. Cracked fillings can expose the underlying tooth to bacteria and lead to decay.
• Rough Edges: If your filling no longer feels smooth or you notice any sharp or rough edges, it could mean the material is wearing away.

Extending the Life of Your Fillings

While fillings don’t last forever, there are steps you can take to maximise their lifespan. Here are some simple but effective tips:

• Practise good oral hygiene: To help get rid of plaque and germs that might lead to decay around your fillings, use mouthwash, floss once a day, and brush twice daily with fluoride toothpaste.
• Avoid hard and sticky foods: Don’t chew hard candies, ice, or sticky foods like toffee, which can damage or loosen your fillings.
• Use a night guard: If you grind your teeth at night, ask your Belmont WA dentist about a custom night guard. This can protect your fillings from unnecessary wear.
• Schedule regular dental visits: Keep up with your routine checkups and cleanings. Your dentist will track the state of your fillings and advise you when a replacement is necessary.
