Onlays are bespoke, hand-crafted restorations which are used to fill large cavities. When cavities become too large the cusps on the back of the teeth can become weak and may even break if they are not protected or strengthened. This can make the cavity even larger and the tooth may eventually need to be removed. Onlays are used to strengthen the tooth, protect the cusps and restore normal function.
Onlays are custom-made for each patient and can be created from composite material or precious metals, including silver and gold. Composite onlays are designed to match the colour of the existing teeth, so they will blend in and remain invisible when you open your mouth. If you have metal onlays and feel that they are too visible, they can be replaced with ceramic onlays, which are a much more natural looking solution.
The tooth will be anaesthetised to prevent pain and then the cavity will be cleaned and any dead tissue removed. An impression will be made of the tooth and sent to a dental laboratory to be fabricated, which will then be returned and fitted using dental cement. This is then polished to create an attractive finish.
Onlays at Time Dental are an excellent option for people who have suffered cavities and want to give their smile back its natural strength and appearance.
Book an onlays consultationA dental onlay is a type of dental restoration used to repair a tooth that has mild to moderate decay or damage. Unlike a filling, which is moulded into place within the tooth, an onlay is fabricated outside the mouth and then bonded onto the tooth’s surface to restore its shape, function, and strength. Dental onlays are typically made from materials such as porcelain, composite resin, or gold and are custom-made to fit the specific shape and size of the affected tooth.
Onlays are generally regarded as a long-term solution for restoring your teeth. Generally, they would be expected to last a similar number of years to dental crowns. This is usually around 10-15 years, provided you have good oral hygiene.
You care for your onlays in the same way you would care for your natural teeth. You should brush and floss daily and visit the dentist for routine appointments to ensure your restoration is secure and strong.
Immediately after having your onlays fitted you should take care when eating and avoid eating hard foods. However, you are able to resume eating as normal after a few days.
