Dental Inlays and Onlays: Perfect Solution for Tooth Repair

 Some teeth may be too damaged for a simple filling, but do not require a full crown. Many people in Australia, including those in Doreen, seek advice from their dentist when faced with this situation. Traditionally, the options were either a large filling or a full crown. A middle-ground option is dental inlays and onlays. These are custom-made restorations designed to fit precisely into the damaged area of a tooth. They are durable and provide a more natural appearance than traditional fillings. 

This guide explains what dental inlays and onlays are, how they differ, when they may be recommended, and their potential benefits for restoring a damaged tooth.

What Are Dental Inlays and Onlays?

Let’s start with the basics. Imagine your tooth has a cavity or a crack. A regular filling is a soft material that the dentist puts directly into the hole and then hardens. It’s like patching a small pothole in the road.

An inlay or an onlay is different. They are both solid, pre-made pieces that are created in a dental lab. Your dentist prepares the tooth, takes a precise mould or digital scan, and sends it off to a special lab. A dental technician then crafts the inlay or onlay to fit the exact shape of the hole in your tooth. Once it’s ready, your dentist cements it into place. This is a much stronger and more durable way to repair a tooth.

Differences Between Inlays and Onlays

The names sound similar, but there’s a simple difference between an inlay and an onlay, and it all comes down to where the damage is on the tooth.

  • Dental Inlays: An inlay is used to repair damage that is contained within the cusps (the pointy parts) of your tooth. An inlay fits within the top surface of the tooth, between the cusps, restoring the cavity while preserving healthy tooth structure.

  • Dental Onlays: An onlay is a bit bigger. It’s used when the damage extends over one or more of the cusps of the tooth. An onlay restores the cavity and one or more cusps of the tooth. It is sometimes referred to as a ‘partial crown’ because it covers part, but not all, of the tooth surface.

So, the choice between an inlay and an onlay depends on how much of the tooth structure needs to be replaced. Your dentist will carefully assess the damage to decide which one is right for you.

When Are Inlays and Onlays Recommended?

You might be wondering, “Why would I get an inlay or onlay instead of a regular filling or a crown?” It’s a great question, and there are specific situations where they are the best choice.

  • When a Cavity is Too Big for a Filling: If a cavity is so large that a traditional filling wouldn’t be strong enough to hold the tooth together, an inlay or onlay is the perfect solution. A large filling can weaken the remaining tooth structure, making it more likely to crack. An inlay or onlay, being solid and custom-made, actually strengthens the tooth.

  • To Repair a Broken or Fractured Tooth: If a tooth has a crack but it’s not severe enough to need a full crown, an onlay can be used to repair the fracture and protect the tooth from further damage. It holds the remaining pieces of the tooth together.

  • To Replace Old, Large Fillings: Old fillings, especially large silver (amalgam) fillings, can sometimes weaken a tooth over time. If a dentist finds that an old filling is starting to fail or the tooth around it is cracking, they might recommend replacing it with a custom inlay or onlay.

  • When You Want a Natural-Looking Restoration: Inlays and onlays are often made from tooth-coloured materials like porcelain, so they blend in perfectly with your natural teeth. This is a big plus for those who want a restoration that is not noticeable, unlike the old-style silver fillings.

Inlays and onlays are a restorative option that preserves more natural tooth structure than a full crown while offering greater durability than a conventional filling.

Benefits of Inlays and Onlays Over Other Restorative Options

Choosing an inlay or onlay offers several advantages over other restorative options:

  • Preserving Natural Tooth Structure: Inlays and onlays preserve healthy tooth structure. Unlike a crown, which requires more extensive tooth preparation, these restorations only replace the damaged or decayed areas.

  • Exceptional Durability and Strength: Since they are made in a lab from a single, solid block of material, inlays and onlays are incredibly strong. They can withstand the forces of chewing and biting much better than a regular filling. This means they are less likely to crack or break over time.

  • Superior Aesthetics: As mentioned earlier, they can be made to match the exact shade of your tooth. They don’t stain over time, and they look completely natural, making it almost impossible to tell you’ve had dental work done.

  • Better Fit and Seal: Because they are custom-made from a precise mould, they fit the tooth perfectly. This tight fit helps prevent bacteria from getting under the restoration, thereby reducing the risk of future decay. A better seal means a healthier tooth in the long run.

  • Longer Lifespan: While a filling might last 5-10 years, inlays and onlays can often last for 15-20 years or even longer with good care. Their long-term durability makes them a great investment in your oral health.

The Procedure for Getting Inlays and Onlays

The process for getting an inlay or onlay is typically completed in two visits, though some modern dental practices can do it in one using advanced technology like CEREC. Here’s a quick look at what you can expect:

Visit 1: Preparation

  1. Numbing and Examination: Your dentist will first numb the area around the tooth so you don’t feel any discomfort. They will then carefully remove any old filling material, as well as the decayed or damaged parts of the tooth.

  2. Tooth Preparation: The tooth is shaped to prepare it for the inlay or onlay. The dentist ensures the walls of the cavity are strong and the edges are clean.

  3. Taking a Mould: A precise impression (mould) of your tooth is taken. This can be done with a putty-like material or with a digital scanner. This impression is what the dental lab will use to create your custom restoration.

  4. Temporary Restoration: To protect your tooth while the lab is making your inlay or onlay, the dentist will place a temporary filling. This will keep the tooth from getting sensitive or damaged.

Visit 2: Placement

  1. Checking the Fit: When you return for your second appointment, the dentist will remove the temporary filling. They will then carefully place the new inlay or onlay on your tooth to make sure it fits perfectly and the bite is correct.

  2. Bonding the Restoration: Once everyone is happy with the fit, the dentist will use a strong dental cement or bonding material to permanently attach the inlay or onlay to your tooth.

  3. Final Polish: The dentist will then polish the surface and make any final adjustments to ensure it is smooth and blends in with the rest of your teeth. The result is a durable, natural-looking restoration that functions effectively for chewing and biting.

Material Options for Inlays and Onlays

Inlays and onlays can be made from a few different materials, each with its own pros and cons. The best choice for you will depend on the location of the tooth and your personal preferences.

  • Porcelain (Ceramic): This is the most popular choice because it looks the most natural. Porcelain can be colour-matched perfectly to your tooth, so it’s virtually invisible. It’s also very strong and stain-resistant. This is the top choice for teeth that are visible when you smile.

  • Composite Resin: This is the same material used for tooth-coloured fillings. It’s a good option and can be made in a lab for a better fit than a direct filling. It’s less expensive than porcelain but not quite as strong or long-lasting.

  • Gold: Gold was a traditional choice for inlays and onlays because it’s extremely durable and resistant to wear. It’s a great option for back teeth that take a lot of chewing pressure. The main drawback for most people is its colour, which is not natural-looking.

Your dentist will discuss the best material for your specific situation. For example, a dentist Doreen will recommend the most suitable material and type of restoration based on the tooth’s location and condition.

How Long Do Inlays and Onlays Last?

As we mentioned, one of the biggest benefits of inlays and onlays is their longevity. While a regular composite filling might need to be replaced after 5-10 years, inlays and onlays made from porcelain or gold can last for 15, 20, or even 30 years with good oral hygiene and regular dental check-ups. 

The long lifespan of inlays and onlays may reduce the need for frequent replacements, supporting long-term oral health.

Caring for Your Inlays and Onlays

Caring for an inlay or onlay is no different from caring for your natural teeth. These restorations are integrated with the tooth and should be cared for as part of routine oral hygiene.

  • Brush and Floss Regularly: Brush twice a day with fluoride toothpaste and floss at least once a day. Pay special attention to the areas around the inlay or onlay.

  • Avoid Hard Foods: Try to avoid chewing on extremely hard foods or objects like ice, lollies, or pens, as this can damage any dental restoration, including an inlay or onlay.

  • Regular Dental Check-ups: Visiting your dentist for a check-up and clean every six months is crucial. Your dentist can check the condition of your inlay or onlay and make sure it is still in good shape.

Potential Risks and Considerations

While inlays and onlays are very safe and effective treatments, there are a few things to keep in mind.

  • Sensitivity: It’s normal to feel some tooth sensitivity to hot or cold temperatures for a few days after the procedure. This should go away on its own.

  • Chipping: Although they are strong, porcelain inlays and onlays can chip, just like natural teeth.

  • Cost: The cost of an inlay or onlay is higher than a regular filling, as they involve more time, lab work, and a higher-quality material. The durability and longevity of inlays and onlays make them a practical long-term restorative option.

Cost of Inlays and Onlays

The cost of dental inlays and onlays can vary widely depending on several factors:

  • Material: Porcelain and gold are more expensive than composite resin.

  • Tooth Location: The size and location of the restoration can affect the price.

  • Dentist’s Fees: The price will vary from one dental practice to another.

  • Insurance Coverage: Many private health funds in Australia provide a rebate for this type of restorative work. It’s always a good idea to check with your fund to see what you are covered for.

While the initial cost is higher than a simple filling, remember to think of it as a long-term investment. The money you save from not having to replace a failing filling or needing a full crown later on can make it a very cost-effective choice in the long run.

Conclusion

For many people, the decision of how to repair a damaged tooth can be a stressful one. Traditional options like large fillings or full crowns may not always be the best solution. Dental inlays and onlays offer a fantastic, modern alternative that is both conservative and incredibly effective.

They preserve more of your natural tooth, are extremely strong and durable, and can be made to look completely natural. If you have a damaged tooth and are looking for a long-lasting and aesthetically pleasing repair, an inlay or onlay might be the perfect solution for you. They are a smart investment in your oral health and can help keep your smile looking great for many years to come.

FAQs

Q: Are inlays and onlays painful to get? 

A: No, the procedure is done under local anaesthetic, so you won’t feel any pain. You might experience some minor sensitivity afterwards, but this usually goes away quickly.

Q: Can a cracked tooth be repaired with an onlay? 

A: Yes, an onlay is an excellent way to repair a cracked tooth, as it covers and protects the weak part of the tooth, holding it together and preventing the crack from getting worse.

Q: How do I know if I need an inlay or an onlay? 

A: Your dentist will be able to tell you after a thorough examination. They will assess the size and location of the damage to recommend the best option for you.

Q: Is it true that onlays are also called “partial crowns”? 

A: Yes, that’s a common term because an onlay covers one or more of the cusps (points) of a tooth, but not the entire surface, making it a “partial” crown.

Concerned About a Damaged or Failing Tooth?

If you have a damaged or failing tooth, consult the dentists at SmileWorks Dental Doreen about whether an inlay or onlay is appropriate. 

These restorations can preserve more natural tooth structure and provide a durable, aesthetically pleasing result.
