What are dental fillings really made of? Why do some crowns look just like real teeth while others don’t? And how do you know which material is right for you? If you've ever sat in the dentist’s chair wondering what exactly is going into your mouth, you're not alone. Dental restorations may seem routine, but the materials used can make a big difference in comfort, appearance, and longevity.
In modern dentistry, materials like composite resin, porcelain, gold, and amalgam are commonly used for fillings, crowns, and other restorations. Each has its own advantages and ideal applications—composites blend naturally with teeth, metals are incredibly durable, and ceramics offer a lifelike appearance.
This article explores the key materials used in dental restorations, their properties, and when each is typically recommended. Read on to gain insight into how your dentist chooses the best option for your smile—and what it means for your long-term oral health.
Resin composites are widely used in fillings and cosmetic restorations. They are made of a plastic-like matrix (such as Bis-GMA or UDMA), fine fillers like glass or zirconia particles, and special agents that help bind everything together.
The main advantage of resin composites is that they look very natural and blend well with real teeth. They also allow for minimal drilling and can bond strongly to the tooth surface. However, they can shrink slightly when they harden, which may cause small gaps or sensitivity. Over time, they can also wear down or become stained.
Glass ionomers are commonly used in fillings, especially in children or non-load bearing areas. They are made of a mix of glass powder and a special acidic liquid that sets through a chemical reaction.
Their biggest benefit is that they release fluoride, which helps protect against cavities. They also stick to teeth without the need for strong adhesives. But they are not as strong or long-lasting as resin composites, and they can wear down more easily with chewing over time.
Dental ceramics are used for crowns, veneers, and bridges because of their excellent appearance and strength. Common types include feldspathic porcelain, lithium disilicate, and zirconia.
Ceramics are very strong, resistant to staining, and look very natural, making them ideal for visible areas. They are also safe for the body and don't cause irritation. On the downside, some ceramics can be brittle and may chip if not handled carefully. They are also harder than natural teeth and might wear down the opposing tooth if not polished properly.
Metal alloys have been used in dentistry for decades and are known for their strength and durability. These include gold, nickel-chromium, cobalt-chromium, and titanium.
Their strength and long-lasting performance make them ideal for bridges, crowns, and implants, especially in back teeth. They rarely break and are highly resistant to corrosion. However, they don’t match the natural tooth color and may cause allergic reactions in some people, especially with base metals like nickel.
Newer dental materials are being developed to offer even better performance. These include bioactive glass, nanocomposites, and hybrid ceramics.
These advanced materials can help teeth repair themselves, offer better strength, and look very natural. They also work well with modern digital dental tools. But they can be more expensive and may require special training or equipment to use properly.
OVO offers a complete range of high-quality dental materials, from traditional to cutting-edge solutions. Visit our Products page to explore options that match your needs. Work with OVO to ensure safe, effective, and modern dental care.
Choosing the right material requires balancing multiple factors to meet clinical and aesthetic goals:
At OVO, we offer detailed material data sheets and expert support to help you select the ideal product for each indication. Please contact us for technical specifications and case studies.
Nanofillers enhance mechanical strength and polishability. These ultra-fine particles improve wear resistance while maintaining excellent aesthetics.
Digital workflows now enable additive manufacturing of crowns, bridges, and surgical guides with high precision and reduced turnaround time.
Emerging bioactive glasses and resin formulations can release ions to encourage remineralization and inhibit bacterial growth.
New generations of multilayer zirconia offer improved translucency without sacrificing toughness, ideal for full-contour esthetic restorations.
The most common dental materials include resin composites, glass ionomer cements, ceramics (like zirconia and lithium disilicate), and metal alloys. Each is selected based on the specific clinical need, durability, and aesthetic requirements.
Composite resins are typically preferred for aesthetic fillings due to their tooth-like appearance and bonding properties. For deeper cavities or areas under high stress, glass ionomers or amalgam may also be considered.
Yes, modern dental materials are rigorously tested for biocompatibility. OVO ensures all products meet global safety and quality standards, minimizing allergic reactions and ensuring long-term performance.
Longevity depends on the material type, placement technique, and oral hygiene. For example, ceramic crowns can last 10–15 years or longer, while composite fillings may need replacement after 5–7 years.
While rare, some patients may experience reactions to metals (like nickel) or monomers in certain resins. OVO offers hypoallergenic alternatives to ensure safe use for all patients.
Understanding the wide range of dental materials and their properties is essential for delivering durable, esthetic restorations. By considering biocompatibility, mechanical strength, aesthetics, and cost, you can select the most suitable material for each clinical scenario.
