Inlays and onlays (also known as indirect fillings) can be used to restore areas of more extensive decay, damage or wear that are too large to be treated with a normal filling, and can offer a less invasive and more affordable alternative to a crown.
A long lasting restorative solution, they are usually placed in teeth at the back of the mouth or can be used to repair large areas on the front teeth.
Unlike a filling, inlays and onlays are created outside the mouth from an impression taken of the tooth. An inlay is cemented within the cavity and an onlay covers more of the tooth when a repair needs to include one or more cusps (the points of the tooth) or fully cover the biting surface. They are made from hardwearing materials including porcelain and composite resin, and if aesthetics is not an option, gold can be used to provide a particularly durable restoration.
Tailored to fit
More of the healthy tooth is preserved
Easier to keep clean
They protect and strengthen the tooth
More durable and stable than fillings
Natural looking options
Any areas of decay or old fillings are removed and the tooth is cleaned.
An impression is taken and this is used by a dental laboratory to create the inlay or onlay so it will exactly match the area to be filled.
So the prepared cavity can be protected while the inlay or onlay is being produced, a temporary restoration can be fitted.
When ready the inlay or onlay is checked for fit and comfort, and then fixed permanently in place with a strong dental adhesive.
Inlays and onlays are very stable restorations that will fit a damaged tooth perfectly to provide superior protection and the ability to withstand stronger chewing forces. The affected tooth requires minimal preparation and, as the inlay or onlay is tailored to fit, they can be easier to keep clean than other restorations. When kept properly maintained, with effective cleaning and regular check-ups, inlays and onlays can last for years.
What is endodontics?
Endodontics is better known as Root Canal Treatment. Root Canal Treatment is necessary when the nerve of a tooth becomes irreversibly damaged, and has to be removed.
Periodontal disease affects the gums, bone and other supporting tissues of the teeth. Most individuals suffer gum inflammation from time to time, around 10% of the population appear to suffer from the more severe forms.
