Inlays & Onlays
Inlays and Onlays Treatment to Restore Damaged Teeth in Camden
In simple words, inlays and onlays can be described as special type of fillings to restore your damaged teeth. When the filling is applied to the inner tooth cavity, it is referred to as an inlay. Likewise, when it is applied to the outer tooth structure, it is termed as an onlay.
What are dental inlays and onlays?
Inlays and onlays are forms of indirect fillings. These restorations are custom-made outside the mouth, typically in a dental lab, before being bonded to the tooth. Here’s a detailed explanation of what inlays and onlays are:
Dental Inlays
Dental inlays are custom dental restorations, primarily made of gold, porcelain, or composite materials, and are used to restore moderately decayed or damaged teeth. These restorations are placed inside the central area of a tooth, leaving a little space, while retaining the remaining structure of the tooth. Inlays are best recommended for cases where damage can’t be repaired by filling alone but is not too severe enough to warrant a full crown. These restorations give strength and stability to make it possible for the tooth to withstand natural masticatory functions.
Dental Onlays
Dental onlays, also referred to as partial crowns, extend past the central area of the tooth to include one or more cusps or points of the tooth. Like inlays, they are created from durable materials such as gold, porcelain, or composite and are applied to moderately damaged teeth to restore them. Onlays save as much of the original tooth as possible while reinforcing its strength and functionality for a more conservative alternative than full crowns.
Inlays, Onlays, Fillings, and Crowns: Similarities and Differences
Inlays vs. Fillings
Fillings are the simplest and most common type of dental restorations. They are used to treat small cavities by filling the decayed area with materials like composite resin, amalgam, and glass ionomer cement. Fillings are quick and straightforward to place, often completed in a single visit. However, they are generally best suited for minor damage and may not offer the same level of strength as more advanced restorations.
Inlays, on the other hand, are ideal for larger cavities that fillings cannot effectively restore. They are custom-made from durable materials, making them stronger and more resilient than traditional fillings.
Because inlays are fabricated outside the mouth in a dental lab, the process typically requires two appointments: one to prepare the tooth and make an impression and another to bond the inlay in place. This extra step ensures a precise fit and improved longevity.
Onlays vs. Crowns
An Onlay may be recommended if the damage extends beyond the central area to the cusps of the teeth. Onlays, also known as partial crowns, cover one or more cusps of the tooth to add strength and protection to a damaged tooth. Like inlays, they are custom-made and require two visits to our dental practice to complete. The conservative approach to onlays conserves as much of the natural tooth structure as possible while offering improved durability and functionality.
Crowns, on the other hand, are the most extensive and comprehensive type of restoration. They fully cover the entire visible surface of the tooth, making them the go-to choice for teeth that have a lot of structural damage, fractures, or decay. While crowns offer full protection and aesthetics, they require more reduction of the tooth during preparation than an onlay.
Indications for dental inlays and onlays
Dental inlays are considered to be the best restorations of choice when direct composite fillings alone cannot offer durability or stability. They are usually indicated in the following scenarios:
- Deep Cavities: In cases where the cavities are too deep for direct composite fillings to restore. They offer structural support, thus protecting the tooth from further damage.
- Fractured Teeth: Inlays help strengthen the compromised regions of cracked teeth and allow for full chewing. They also work exceptionally well at preserving any remaining natural tooth structure.
- Reinforcing Old Fillings: Inlays can replace old or failing amalgam fillings. In addition to enhancing their strength, they provide a natural tooth-coloured appearance and, thus, offer an aesthetic advantage over amalgam.
Inlays and Onlays: What are they made of?
Inlays and onlays can be prepared from various materials which typically include gold, composite resin, and ceramic. All of these materials have unique advantages and disadvantages. Here’s an overview of the mentioned materials:
Gold
Gold has been the material of choice for inlays and onlays for a long time because of its outstanding durability and malleability. It closely mimics the physical properties of natural teeth, making it ideal for reinforcing weakened tooth cusps affected by cavities or trauma.
While gold restorations are long-lasting and highly resistant to fracture, they are less popular today due to the growing demand for tooth-coloured alternatives. However, gold remains a practical choice for areas where aesthetics are less critical, such as the back molars, and for cases where traditional fillings repeatedly fail.
Pros
- Extremely durable and malleable, offering superior strength.
- Minimal risk of fracture.
- Stain-resistant, maintaining long-term appearance.
Cons
- Does not blend with natural tooth colour.
- More costly than other materials.
Ceramic (Porcelain)
Ceramic inlays and onlays are made from porcelain. This material is very desirable because of its natural look. These restorations are very close to the colour, shape, and texture of the teeth and therefore, are an excellent aesthetic option.
Ceramic is hard-wearing and stain-resistant, but not as elastic as gold. The hardness can make the ceramic prone to cracking with intense pressure, making it better suited to more moderate restorations than heavy-duty ones.
Pros
- Strong and hard-wearing, excellent for moderate restoration requirements.
- Coloured to match the tooth, creating a natural blend with surrounding teeth.
- Resistant to stains, maintaining good aesthetic qualities.
Cons
- Less durable than gold.
- More prone to breaking due to inherent brittleness of ceramics.
Composite Resin
Composite resin is a versatile, tooth-coloured material, often used for inlays and onlays, specially in cases where traditional fillings are not sufficient. Although it has a natural appearance, its strength and durability are lower compared to gold or ceramic.
Composite restorations are an economical option, but they lack the malleability of gold and the fracture resistance of porcelain. They also are not stain-resistant and over time, they may discolour.
Pros
- Stronger and more durable than traditional fillings.
- Blends with natural teeth. Provides a natural shade of tooth-coloured finish.
Cons
- Less robust as compared to gold or ceramics.
- Not malleable like gold and hence less easily fitted to perfection.
- Subject to staining after a prolonged time.
Selecting the Ideal Material
The selection of the appropriate material for a dental inlay or onlay is based on the tooth’s position, the extent of the damage, and individual preferences. Although gold cannot be rivalled in terms of strength, ceramic and composite materials are also aesthetically appealing and may be used to make restorations that closely resemble natural teeth. Discuss your needs with our expert dentists to determine the most suitable material for your restoration.
Key Considerations in the Choice of Material
-
- Tooth Position The position of the tooth dictates the material to be used. Ceramic inlays are more suited for front teeth because they have a natural appearance, whereas gold alloys are best suited for back teeth that need extra durability.
- Functional Needs The material must withstand the functional forces placed on the tooth. Gold is highly durable and suitable for high-stress areas, while ceramic or composite resins are better suited for areas where aesthetics are a priority.
- Patient Preferences Individual preferences also influence the choice. Patients seeking a natural look may opt for ceramic or composite, whereas those prioritising durability and longevity may choose gold.
- What we recommend
Material selection by our team of highly skilled dentists is important. They will recommend the best material based on a comprehensive evaluation of your oral health, bite forces, and long-term treatment goals.
The Purpose and Benefits of Dental Inlays and Onlays
Dental inlays and onlays have been a versatile and successful restoration option for teeth. In cases where traditional fillings lack durability or aesthetics, dental inlays or onlays are utilised. Here’s how they enhance modern dental care.
- Preservation of the Natural Tooth Structure
These restorations are made to fit perfectly within the prepared cavity of a tooth, thereby ensuring the least amount of removal of healthy tooth tissue.
This helps in conserving the structural integrity of the tooth and prevent any further damage or decay. - Superior Strength and Durability
Inlays and onlays are made of heavy-duty materials such as gold, porcelain, or composite resin. - This makes them have stronger and more wear-resistant features than traditional fillings. The durability helps in eliminating frequent repairs and replacements that would be necessary.
- Better Aesthetics
Unlike silver amalgam fillings, which are noticeable and may darken over time, inlays and onlays are custom-designed to blend perfectly with the natural colour and translucency of your teeth. Therefore, they are a perfect option for filling teeth in the visible area as well, making them appear natural and aesthetically pleasing. - Safe and Biocompatible Materials
Modern inlays and onlays are made from bio-compatible materials that are gentle with the oral tissues, thus offering a reduced risk of allergic reactions and irritation. This makes this restorative treatment safe and comfortable for patients.
These restorations are precision and durability-based, plus aesthetically pleasing they offer a simple yet reliable solution for tooth restorations. They strike a balance between function and form, allowing patients to remain healthy and have a perfectly natural-looking smile.

Aftercare Tips for Inlays and Onlays
Even though recovery from an inlay or onlay placement usually takes only a few days, proper oral hygiene must be observed to avoid the growth of plaque and ensure the longevity of the restoration. Here are some essential aftercare tips to follow:
Maintain Proper Oral Hygiene
Inlays are often placed in areas inaccessible to our toothbrush; thus, regular interdental cleaning is necessary along with other basic oral care habits such as:
- Brush your teeth twice a day.
- Floss daily to clear out debris between the teeth.
- Rinse with an antibacterial mouthwash to lower oral bacteria.
Watch Your Diet
Change your diet to help keep your restorations healthy:
- Avoid sugar to limit the possibility of decay.
- Avoid highly acidic foods, such as candy, coffee, dark fruits, and processed items, which cause erosion of enamel.
- Steer clear of sticky foods that can dislodge or damage your inlay or onlay.
Bad Habits
Some bad habits may compromise the integrity of your restoration. Don’t do the following:
- Chew or bite on hard objects like ice or pen caps that can crack your inlay or onlay.
- Smoke, as this will cause harm to your gums and weaken the areas surrounding your restoration.
Visit our experts Regularly!
Regular dental checkups are essential for keeping an eye on the status of your inlay or onlay. In the process, our experts will:
- Examine for signs of leakage, damage, or disease.
- Proper preventive care will help extend the lifespan of your restoration.
With aftercare practices such as the ones mentioned above, you’ll be able to maintain good oral health and maintain the strength of your inlays and onlays.
