Dental Inlays and Onlays

What are Dental Inlays and Onlays?

Inlays and onlays are indirect dental restorations so that they are created out of your mouth at a lab. An inlay or onlay is usually utilized when a pit is too big for an easy filling.

Inlays and onlays will raise a tooth's power by around 75 per cent.
There Are Lots of Advantages of inlays and onlays, such as:
More immune to damage and fractures than conventional cavity fillings
Improve the organic aesthetic and look of teeth
Custom designed to match a patient's teeth arrangement, colour, and shape
Based on the individual's cavity and fracture risk, they could last up to 30 Decades.


A dental inlay is constructed from a sound, custom-formed substance. Inlays are thrown to form with golden or milled to shape with ceramic-based upon the cavity dimensions and thickness.
An inlay is moulded to fit into the bottoms of the tooth. It doesn't extend across the cusps of the teeth.


Very similar to inlays, dental onlays are made from a sound, custom-made substance. An onlay is more significant than an inlay but smaller than a crown. It's used to fill a bigger cavity which stretches across the cusps of a tooth.

Inlay/Onlay Materials

Inlays and onlays can be made from gold, composite ceramic or ceramic materials:


Previously, gold has been the substance of choice for inlays and onlays due to its strength. Since gold is very durable, it protects diminished teeth cusps brought on by cavities and injury.
Nowadays, with the debut of tooth-coloured restorations, gold dental restorations are somewhat less common.

Teeth with dental gold inlay

Gold inlays are usually used if a pit is filling fractures. Composite or ceramic (ceramic ) inlays might be selected for aesthetic reasons. However, they're more prone to damage.
Many meddo recommend choosing gold inlays or onlays in regions of the mouth where appearance isn't necessary, as the back molars.


Very Powerful and malleable
Unbelievably low Prospect of fracture


Doesn't blend in with your natural tooth colour
Costlier than other restorations
Ceramic (Porcelain)
Ceramic inlays and onlays are made from porcelain. In dentistry, porcelain can make tooth-coloured restorations that mimic the colour, shape, and function of natural teeth.

Powerful and durable material
Less prone to fracture compared to conventional fillings
Blends in with the colour of your teeth


More delicate than gold restorations
Despite its potency, ceramic is a stiff material with an increased risk of fracture.

Composite Resin Composite inlays and onlays are utilized to fill cavities which are too big for conventional fillings. They're a substitute for ceramic or gold restorations and perform the very same functions.

Healthier and less prone to fracture compared to conventional dental fillings

Weaker than gold restorations
Less Expensive than gold or ceramic restorations
Not stain-resistant

Inlay/Onlay Procedure: Step-By-Step

Measure 1 - Cavity filling elimination (if necessary)

Frequently times, inlays and onlays replace cracked or damaged intestines fillings.
When there's a present filling in your tooth, your meddo will eliminate it before placement. Any cavitated tooth tissue can be removed, which leaves a hollowed-out cavity.
Afterwards, your dentist prepares and contours your enamel, allowing for more comfortable positioning of the inlay or onlay.

Measure 2 - minute of the tooth (inlay/onlay mould )

During the initial trip, a mould is removed from their cavitated or damaged tooth. This mould will help you and your dentist decide which stuff to use for your inlay or onlay (ceramic, gold, or mix ). When ceramic is selected, you'll also decide on the colour of this restoration on this trip.

Measure 3 - minute filling positioning

While the inlay or onlay has been ready, a temporary filling is set to seal the cavity. This helps prevent additional corrosion and protects your enamel from thermal stimulation (sensitivity brought on by hot or cold liquids).

Measure 4 - Inlay/onlay positioning

Following the recovery is created, you may set up an additional appointment with your dentist to have the inlay or onlay placed.

Your meddo will administer a local anaesthetic (only if asked ) to decrease pain and increase relaxation in this appointment. Afterwards, the temporary filling material is pulled from the cavity, and the inlay or onlay is cemented into the tooth.
Dentists can generally eliminate the temporary filling and put the inlay or onlay without inducing substantial distress.

Porcelain and composite inlays and onlays can now be made in-office with CAD/CAM technologies and milling machines such as CEREC. It is the same technologies that dentists use to create same-day implants. In such scenarios, you would experience measures two and one, skip a step and proceed straight to measure four within precisely the same trip.

Aftercare Tips

The healing period for inlays and onlays requires a couple of days. Nonetheless, your teeth remain vulnerable to oral and plaque bacteria buildup over time. It's critical to practice good oral hygiene to maintain the restorations clean and powerful.

To Decrease the chance of dental disease, meddo recommend these tips:

Cosmetic Dentistry

Inlays stretch to the interdental areas of your mouth (between your teeth). These are difficult places to wash and need routine interdental cleanings, for example, flossing and having an interdental toothbrush. Fundamental dental care practices will also be necessary, for example, brushing two times daily and rinsing with mouthwash to destroy germs.


Patients ought to decrease sugar consumption following inlay or onlay placement. Dentists also advise avoiding highly acidic foods and beverages, including candy, coffee, milk, dark fruits, and processed meals.


Inlays and onlays must be routinely assessed by your dentist every six months. Your dentist will examine the tooth for indications of damage, leakage, and disorder during these appointments.
