Dental Inlays in Budapest - when a filling is not enough, but a crown is not yet needed

Inlay, onlay and overlay: lab-made, precisely fitted restorations for larger-scale tooth damage

An inlay is a restoration made individually in a dental laboratory, which, in terms of its size and area of use, represents a solution between a traditional filling and a crown. It is recommended when the tooth's damage is greater than what a traditional aesthetic filling could safely and durably replace, but the tooth's healthy structure is still sufficient that a full crown is not yet needed. At PureDental's Budapest clinic we work with inlay, onlay and overlay restorations alike, depending on the extent and location of the damage.

The three types

What is an inlay, onlay and overlay? The three types

Inlays, onlays and overlays all belong to the same family of indirect restorations. These are restorations made individually in a dental laboratory, differing from each other in size and extent. The most important difference is how much of the tooth, and which surfaces, they cover.

Extent
01Smallest extent

Inlay

CoversThe area between the cusps

An inlay restores the inner part of the chewing surface, the area between the cusps. In this case the cusps themselves are not covered, because they are still stable and can safely bear load.

An inlay is usually a smaller-to-medium sized restoration, recommended when the tooth structure loss is greater than what a traditional filling could safely and durably replace. It can be a good choice, for example, when decay or the replacement of an old filling leaves behind a larger cavity, but the tooth structure is still strong enough.

Extent
02Medium extent

Onlay

CoversOne or more cusps as well

An onlay is a larger restoration that covers not only the inner part of the chewing surface but also one or more cusps. This may be necessary when the cusps have weakened, been damaged, or would no longer be safely load-bearing on their own.

An onlay often comes into consideration for greater tooth structure loss, the replacement of an old, extensive filling, a risk of fracture, or the restoration of a root-canal-treated tooth. In these cases the goal is not only to seal the cavity, but also to strengthen the tooth and reduce the risk of further fracture.

Extent
03Largest extent

Overlay

CoversThe entire chewing surface, every cusp

An overlay is the largest type of restoration, covering the tooth's entire chewing surface and all of its cusps. It can be used when the tooth has weakened significantly, but the remaining tooth structure still allows it to avoid being fully reshaped for a crown.

An overlay can be made, for example, in cases of extensive decay, a large old filling, wear, a crack, or more significant damage to the chewing surface. Its advantage is that in certain cases it can be a gentler alternative to a crown, since the tooth's shape, stability and chewing function can be restored while removing less healthy tooth structure.

Decided by an individual examination

Choosing the right solution is always based on an individual examination. The decision is influenced by the extent of tooth structure loss, the thickness of the remaining tooth walls, the bite relationship, aesthetic requirements, and whether the tooth is vital or root-canal treated.

Which restoration, when?

When is an inlay needed, when an onlay, and when an overlay?

Inlay: Cusps intact

An inlay is used when decay or the removal of a previous filling leaves behind a cavity that requires a larger or more durable solution than a traditional filling, but the tooth's cusps are still intact, stable, and do not need separate reinforcement.

Onlay: Cusps affected

An onlay is used when the damage already affects one or more cusps, or the tooth structure has weakened so much that the remaining tooth walls could no longer safely bear the chewing force on their own. This can occur, for example, with a large old filling, a risk of fracture, or a root-canal-treated tooth, especially when significant tooth structure loss is also present.

Overlay: Protecting the entire chewing surface

An overlay is used when the tooth's entire chewing surface and all of its cusps need protection, but the tooth's condition still allows it to avoid a full crown. An overlay is a larger restoration that can stabilise a weakened tooth while, in certain cases, offering a gentler solution than a crown.

Common goal: preserving your own tooth

In all three cases the common goal is to preserve as much healthy natural tooth structure as possible, and, whenever clinically feasible, to avoid the more extensive tooth reduction required for a crown. The right solution is always determined based on an individual examination, taking into account the extent of tooth structure loss, the condition of the cusps, bite relationships, and, if needed, the results of an X-ray.

Choosing a material

What material are dental restorations (inlay, onlay, overlay) made from?

An inlay, onlay or overlay can be made from several different materials. Choosing the right restoration material is always an individual decision, influenced by the tooth's position, the extent of tooth structure loss, bite relationships, aesthetic requirements, the presence of teeth grinding, and the patient's long-term expectations.

Pressed ceramic, E-max

  • Tooth-coloured
  • Wear-resistant
  • Colour-stable

Lithium disilicate-based E-max pressed ceramic is an aesthetic, tooth-coloured and high-strength solution, especially popular for inlays, onlays and overlays. Thanks to its natural light transmission it can give a very beautiful aesthetic result, making it a good choice not only for back teeth but also in more visible areas.

A ceramic restoration fits precisely into the prepared tooth, is wear-resistant and colour-stable, and with the right bonding technique can provide a stable restoration in the long term. It is also frequently used on back teeth, especially when durability, aesthetics and a natural bite feel need to be preserved together.

Laboratory composite, for example Gradia

  • Tooth-coloured
  • More flexible
  • Gentle on opposing teeth

Laboratory-made composite restorations, such as Gradia-type materials, are built up in layers and are capable of reproducing a natural tooth colour. They can offer an aesthetic, more flexible solution in certain clinical situations.

One advantage of a composite restoration is that it can be gentler on the opposing teeth than a harder ceramic restoration. Because of this, it may also be considered in certain cases, such as less favourable bite conditions or teeth grinding, although this always requires an individual dentist's decision. In cases of severe teeth grinding, wearing a night-time bite-raising splint is often recommended to protect both the restoration and the patient's own teeth.

Gold

  • Extremely durable
  • Precise marginal fit
  • For back teeth

Gold inlays are a classic, premium solution known as an extremely durable, well load-bearing restoration. Their great advantage is that a precise marginal seal can be achieved, they withstand chewing force well, and they can be gentle on the opposing teeth.

From an aesthetic point of view, a gold restoration is mainly recommended for back, less visible teeth. Although it is a less commonly chosen solution today, thanks to its durability and functional properties it can still be an excellent alternative in certain cases.

The treatment process

How is an inlay made? The process of making a restoration

In brief: how is a restoration made?

When making a restoration, the dentist removes the decayed or damaged tooth tissue, then precisely prepares the site for the restoration. The exact shape of the tooth is then recorded with a digital scan or a traditional impression, based on which the dental laboratory prepares the custom inlay, onlay or overlay. At the second appointment the restoration is tried in, the fit, colour and bite are checked, and it is then permanently bonded into the tooth.

1First appointment

Appointment 1: preparation and impression taking

The first treatment begins with local anaesthesia if needed, so the procedure is pain-free. The dentist removes the decayed, damaged or weakened tooth tissue, as well as the old, unsuitable filling if necessary.

The precise site for the restoration is then prepared. This step is especially important, because an inlay, onlay or overlay is not made directly in the mouth like a traditional composite filling, but in a dental laboratory, custom-fitted to the tooth's shape.

After the tooth is prepared, the exact relationship between the tooth and the bite is recorded with a digital scan or a traditional impression. Based on this, the dental technician makes the restoration so that it fits precisely into the prepared tooth, restores chewing function, and looks naturally aesthetic.

Until the laboratory work is ready, the tooth is protected with a temporary filling. This protects the prepared tooth, reduces sensitivity, and helps the patient eat and speak comfortably until the next appointment.

Appointment 2: try-in and final bonding

At the second appointment the temporary filling is removed, and the inlay, onlay or overlay made in the dental laboratory is tried in. At this point we check whether the restoration fits precisely, and whether its colour, shape, seal and position in the bite are all correct.

Before final bonding, the tooth and the inner surface of the restoration are prepared according to a special bonding protocol. When the clinical situation allows, a rubber dam is used to isolate the site, so that bonding takes place in a dry, well-controlled environment. This is especially important because modern bonding techniques are sensitive to moisture, and precise isolation can contribute to the restoration's durability and a good marginal seal.

After the restoration is permanently bonded, the bite is checked again, and any necessary fine adjustments and polishing are carried out. The goal is for the finished inlay, onlay or overlay to be comfortable, to blend naturally into the row of teeth, and to restore the tooth's function stably in the long term.

After bonding, the restoration becomes usable within a short time, but while the anaesthetic is still working, it is worth being careful when eating, so the patient does not accidentally bite their lip or cheek.

Inlay or filling?

Why is an inlay a better solution than a traditional filling?

For minor decay or a smaller amount of tooth structure loss, a traditional, tooth-coloured composite filling can be an excellent solution. However, for a larger cavity, the replacement of an old large filling, or a weakened tooth structure, an inlay is often the more advantageous option.

An inlay is not made directly in the mouth, but in a dental laboratory, individually, custom-fitted to the tooth's exact shape. Because of this, in certain cases it can provide a more durable, more stable and more precisely fitting solution than a large traditional filling.

The advantages of an inlay for greater tooth structure loss

01

Precise fit

An inlay is made in a dental laboratory based on a digital scan or impression of the tooth. This allows the restoration to fit precisely into the prepared cavity and precisely restore the tooth's shape, chewing surface and contact points.

02

Greater stability for larger cavities

When a significant amount of tooth structure is already missing, a large filling can be more prone over time to wear, cracking or marginal leakage. An inlay, on the other hand, fits into the tooth as a single, individually made restoration, so it can offer a more stable solution for larger-scale loss.

03

More durable shape and chewing surface

The advantage of a lab-made restoration is that the chewing surface, grooves and tooth shape can be formed under controlled conditions. This is especially important for back teeth, where chewing force is greater and precise bite relationships remain decisive in the long run.

04

Can be a better solution when replacing old, large fillings

When an old, large filling no longer seals properly, has discoloured, cracked or decayed underneath, it is not always ideal to replace it with another large filling. In such cases an inlay, onlay or overlay can offer a more durable and safer alternative, while in many cases a full crown can still be avoided.

05

Can be a tooth-sparing alternative to a crown

The goal of an inlay is to preserve as much healthy natural tooth structure as possible. If the tooth's condition does not yet justify a full crown, a restoration can be a gentler solution, because only the damaged or weakened parts need to be replaced, without the need to fully reshape the tooth.

Based on an individual examination: The right decision is always made based on an individual examination. The dentist recommends whether a traditional filling, an inlay, onlay, overlay or a crown would be the safest solution, based on the extent of decay or damage, the amount of remaining tooth structure, bite relationships, aesthetic requirements, and long-term load-bearing capacity.

Durability

How durable is an inlay? How long does it last?

With proper oral hygiene, precise workmanship and regular dental check-ups, a well-made inlay or onlay can be a long-term, durable solution. In many cases it can preserve its function and aesthetics for as long as 10–20 years, and in certain situations even longer.

However, several factors influence its lifespan:

  • the restoration material
  • the amount of remaining tooth structure
  • bite conditions
  • night-time teeth grinding
  • home oral care
  • regular dental check-ups

Gold inlays are traditionally considered one of the longest-lasting restoration solutions, but modern ceramic inlays and onlays can also be exceptionally durable, aesthetic restorations when made with the right indication and precise bonding technique.

Is the damage smaller? An aesthetic filling may well be enough

If the decay or fracture is small to moderate in extent, and the tooth structure is still sufficiently stable, a lab-made restoration is often not needed: a traditional, aesthetic composite filling can also provide a durable, aesthetic solution, in a single appointment.

Dr. Zsolt Majtényi Reviewed by Dr. Zsolt Majtényi Prosthodontist, digital dentistry

What is the difference between an inlay and an onlay?

An inlay fills the inner part of the chewing surface, i.e. the cavity between the cusps, while the cusps themselves remain untouched. An onlay is a larger restoration: it also covers one or more cusps if they can no longer safely bear load on their own. An overlay is the largest type, covering the entire chewing surface and all of the cusps.

My inlay or restoration has come out, what should I do?

If a restoration comes out or loosens, this is usually not an emergency, but it is worth booking a dental check-up as soon as possible. Until then, avoid chewing on the affected side, and do not try to re-glue the restoration yourself, as this could damage the tooth surface or reduce the chances of successful treatment later.

If you have found the restoration that came out, bring it with you to the clinic. In some cases it can be re-bonded, but this can only be decided based on the condition of the tooth and the restoration.

Does bonding an inlay hurt?

Bonding an inlay, onlay or overlay is generally not painful. The tooth is prepared with local anaesthesia if needed, so that the treatment is comfortable and pain-free.

After the final bonding, temporary, mild sensitivity may occur, especially with a deeper cavity or greater tooth structure loss. This usually subsides within a few days. If the tooth remains sensitive to biting, the restoration feels too high, or the discomfort does not go away, it is worth coming in for a check-up.

How much time passes between the two appointments?

Making a lab-produced inlay, onlay or overlay usually requires two appointments. Between the two appointments, typically 1–2 weeks pass while the dental laboratory prepares the custom restoration.

During this time the tooth is protected with a temporary filling, so it is less sensitive, and the patient can comfortably eat and speak until the final restoration is ready.

Can I eat after the restoration is bonded?

After the final bonding of an inlay, onlay or overlay, the restoration becomes load-bearing within a short time. Even so, it is worth waiting until the anaesthetic has completely worn off, because while numb, it is easy to accidentally bite your lip, tongue or cheek.

In the first few hours it is best to avoid very hard, sticky or heavily load-bearing foods, especially if a larger restoration was made. If the restoration feels too high, disruptive or uncomfortable when biting, it is worth coming in for a check-up, as a simple fine adjustment may be needed.

When is a crown needed instead of a restoration?

An inlay, onlay or overlay can be made if the tooth still has enough good-quality natural tooth structure left for stable bonding and long-term load-bearing. If the tooth has weakened too much, a large part of it is missing, several tooth walls are damaged or cracked, or the remaining tooth structure would no longer provide a safe base for the restoration, then making a crown may be justified.

A crown is a larger restoration that surrounds and protects the tooth. This may be especially necessary if the tooth is significantly damaged, root-canal treated, broken to a large extent, or if, due to the bite load, a restoration would no longer be a safe long-term solution.

The decision is always made based on an individual examination. This takes into account the amount of remaining tooth structure, the thickness of the tooth walls, bite conditions, aesthetic requirements and the tooth's long-term retainability.
