Hey there! As an inlay/onlay supplier, I get asked a ton about how inlays and onlays stack up against glass ionomer fillings. So, I thought I’d break it all down for you in a way that’s easy to understand. Inlay/Onlay
Let’s start with the basics. What are inlays and onlays, and what are glass ionomer fillings? Inlays and onlays are custom – made restorations that are used to repair damaged teeth. An inlay is like a puzzle piece that fits inside the cusp of a tooth, while an onlay covers one or more cusps. They’re usually made from materials like porcelain, composite resin, or gold.
On the other hand, glass ionomer fillings are a type of dental filling material. They’re made from a combination of acrylic and glass powder. These fillings are known for their ability to release fluoride, which can help prevent further tooth decay.
Durability
One of the first things people think about when choosing a dental restoration is how long it’s going to last. Inlays and onlays, especially those made from porcelain or gold, are super durable. Porcelain inlays and onlays are resistant to wear and tear, and they can last anywhere from 10 to 15 years or even longer with proper care. Gold inlays and onlays are also incredibly tough and can last a couple of decades.
Glass ionomer fillings, however, aren’t as long – lasting. They tend to wear down faster, especially in areas of the mouth that get a lot of chewing action. On average, you can expect a glass ionomer filling to last around 3 to 5 years. So, if you’re looking for a long – term solution for your damaged teeth, inlays and onlays are probably the way to go.
Aesthetics
Now, let’s talk about looks. In today’s world, aesthetics matter a lot when it comes to dental work. Porcelain inlays and onlays are a winner in this category. They can be color – matched to your natural teeth, so they blend in seamlessly. No one will even know you have a dental restoration. Composite resin inlays and onlays are also pretty good at mimicking the appearance of natural teeth.
Glass ionomer fillings, unfortunately, don’t have the same level of aesthetic appeal. They usually have a more opaque and less natural look compared to inlays and onlays. Over time, they can also discolor, which can make your teeth look less attractive. If you’re worried about how your dental work will look, inlays and onlays are a better choice.
Cost
Cost is always a factor when it comes to any dental procedure. Inlays and onlays are generally more expensive than glass ionomer fillings. This is because they’re custom – made in a dental laboratory, which involves more time and labor. The materials used, like porcelain or gold, are also more costly.
Glass ionomer fillings are less expensive. They’re quicker to place and the materials are relatively inexpensive. However, you have to keep in mind the durability factor. Since glass ionomer fillings don’t last as long, you may end up spending more money in the long run on replacement fillings. So, while the upfront cost of inlays and onlays is higher, they can be a more cost – effective option over time.
Tooth Preservation
When it comes to preserving your natural tooth structure, inlays and onlays have an edge. The process of placing an inlay or onlay involves removing less of the healthy tooth compared to some other restorations. The dentist only needs to prepare the area of the tooth that’s damaged, and then the inlay or onlay is bonded to the remaining tooth structure.
Glass ionomer fillings also require some tooth preparation, but they may not be as precise as inlays and onlays. In some cases, more of the tooth may need to be removed to ensure a good fit. So, if you want to keep as much of your natural tooth as possible, inlays and onlays are a better option.
Biocompatibility
Biocompatibility is important because you don’t want your dental restoration to cause any allergic reactions or other problems in your mouth. Inlays and onlays made from porcelain and composite resin are highly biocompatible. They’re well – tolerated by most people’s bodies and don’t cause any significant side effects.
Glass ionomer fillings are also biocompatible, but they can sometimes release small amounts of chemicals over time. While these chemicals are usually not harmful, they can cause some sensitivity in some patients. So, if you have a sensitive mouth or are prone to allergic reactions, inlays and onlays may be a safer choice.
Placement Process
The placement process for inlays and onlays is a bit more involved compared to glass ionomer fillings. For inlays and onlays, the dentist first prepares the tooth and takes an impression. This impression is then sent to a dental laboratory where the inlay or onlay is custom – made. You’ll usually need to wear a temporary restoration while you’re waiting for the permanent one. Once the inlay or onlay is ready, you’ll go back to the dentist, who will bond it to your tooth.
Glass ionomer fillings can be placed in a single visit. The dentist simply prepares the tooth and then applies the filling material, which hardens quickly. This makes glass ionomer fillings a more convenient option if you’re short on time.
Fluoride Release
One of the big advantages of glass ionomer fillings is their ability to release fluoride. Fluoride helps to strengthen the tooth enamel and prevent further decay. Inlays and onlays, on the other hand, don’t have this fluoride – releasing property. However, you can still maintain good oral hygiene and use fluoride toothpaste and mouthwash to protect your teeth.
So, which one should you choose? Well, it really depends on your individual needs. If you’re looking for a long – lasting, aesthetically pleasing restoration and you’re willing to spend a bit more money, inlays and onlays are a great option. If you’re on a tight budget and need a quick fix, glass ionomer fillings might be the way to go.
