Dental implants are a durable and long-lasting solution for replacing missing teeth. However, because they’re made of metal, it’s natural to wonder: Can dental implants rust? After all, we associate rust with metal exposed to moisture over time.
The good news is that while dental implants are made from metal, the chances of rusting are incredibly low thanks to the materials and technology used. Here’s why you can rest easy when it comes to corrosion concerns.
What Are Dental Implants Made Of?
Most dental implants are crafted from titanium or titanium alloys, which are well-known for being strong, lightweight, and biocompatible. Titanium is the metal of choice in both medical and dental fields because it naturally resists corrosion and integrates well with bone.
Some implants are also made from zirconia, a ceramic material that contains no metal at all. Zirconia implants are popular among patients with metal sensitivities or those looking for a more natural-looking restoration.
Why Titanium Doesn’t Rust Like Other Metals
Titanium has a unique ability to form a protective oxide layer when it comes into contact with oxygen. This layer acts as a barrier, preventing moisture and other elements from causing the type of corrosion you might see in iron or steel. As a result, titanium is highly resistant to rust—even in the moist environment of the mouth.
This resistance makes titanium ideal for long-term use in dental implants. It won’t break down, discolor, or weaken over time like traditional metals might. In fact, titanium implants often last 20 years or more with proper care.
When Implant Corrosion Could Happen
Although it’s rare, corrosion or implant surface degradation can occur under specific circumstances:
- Poor oral hygiene: A buildup of bacteria around the implant can lead to inflammation and acid production, which may damage the implant surface over time.
- Exposure to dissimilar metals: If you have other types of metal restorations in your mouth, like amalgam fillings or crowns, they could potentially react with your implant through a process called galvanic corrosion.
- Manufacturing defects or improper placement: Extremely uncommon, but low-quality materials or placement errors may increase the risk of corrosion.
That said, implant failures due to rust or corrosion are extremely rare and are usually preventable through regular dental care and professional cleanings.
How to Protect Your Dental Implants
To keep your implants in great shape, follow these simple guidelines:
- Brush and floss daily
- Use non-abrasive toothpaste
- Avoid smoking, which can increase the risk of gum disease and implant failure
- Visit your dentist for regular checkups and professional cleanings
If you ever notice unusual signs like a metallic taste, gum irritation, or implant instability, it’s important to reach out to your oral surgeon right away. Your care team can help assess the issue and protect your investment.
Modern dental implants are designed with materials and science that make rust virtually impossible—so you can enjoy a beautiful, functional smile with confidence.
