Tooth fillings are essential for restoring teeth affected by decay or damage. A common question patients ask is, “How long do tooth fillings last?” The answer depends on several factors, including the type of material used, the filling’s location, and your oral hygiene habits. In this blog, we’ll explore the expected lifespan of different fillings and how you can extend their durability.
Types of Tooth Fillings and Their Lifespan
Amalgam Fillings
Amalgam (silver) fillings are durable and often used for molars due to their ability to withstand chewing pressure. They typically last 10 to 15 years, and with proper care, even longer.
Composite Fillings
Composite (tooth-coloured) fillings blend in with your natural teeth but usually last between 5 to 10 years, depending on their location and your oral habits.
Gold Fillings
Gold fillings are exceptionally long-lasting, with a lifespan ranging from 15 to 30 years, making them a premium choice for those seeking durability.
Ceramic Fillings
Ceramic (porcelain) fillings are aesthetically pleasing and durable, lasting around 10 to 15 years when well-maintained.
Glass Ionomer Fillings
Glass ionomer fillings, often used for fillings near the gum line or in children’s teeth, typically last between 5 to 7 years.
Factors Influencing the Longevity of Tooth Fillings
Several factors influence the lifespan of your fillings:
- Material Quality: The durability of fillings varies by material, with gold being the most long-lasting.
- Location of the Filling: Fillings on molars, which bear the brunt of chewing, tend to wear down faster than those on front teeth.
- Bite Pressure: Heavy chewing pressure can shorten the life of your fillings.
- Oral Hygiene: Regular brushing, flossing, and dental check-ups help prevent decay around your fillings.
- Diet: Sugary or acidic foods can weaken fillings over time.
- Teeth Grinding: Bruxism can crack or wear down fillings prematurely.
Signs Your Filling May Need Replacement
Be aware of signs that your filling might need replacing, such as:
- Sensitivity to hot or cold.
- Visible cracks or wear.
- Pain when biting.
- Discolouration around the filling.
- A loose feeling in the tooth.
How to Prolong the Life of Your Fillings
Though fillings don’t last forever, you can take steps to prolong their life:
- Maintain good oral hygiene: Brush and floss regularly to prevent decay.
- Visit your dentist regularly: Regular check-ups can catch issues early.
- Use mouthguards if you grind your teeth: This can protect your fillings from excessive pressure.
- Avoid hard or sticky foods: These can damage your fillings.
By following these tips, you can significantly extend the lifespan of your tooth fillings in Adelaide, ensuring they remain strong and functional for many years to come.
What Happens If a Filling Fails?
If a filling fails, it’s important to replace it quickly. Ignoring a damaged filling can lead to decay, pain, or infection, potentially requiring more complex treatments like crowns or root canals.
Conclusion
The lifespan of your fillings varies depending on the material, their location, and how well you care for them. Regular dental visits and good oral hygiene can help keep your fillings in great shape, ensuring long-lasting results
