An onlay is a solid restoration which can be used to fill a cavity. It is a suitable alternative when it is no longer possible to fit a standard filling because of significant decay or damage in the tooth. Where possible, it is often used in the place of a crown, which can be more expensive and more invasive to fit.
Onlays are most commonly used on the chewing surfaces of the back teeth, where they help to restore strength and function. Your onlay will be placed directly onto the surface of the tooth, fitting within the confines of your other teeth so that it feels comfortable and natural. The onlay fits your tooth perfectly, making it easier to clean and helping to protect the tooth and gums from decay.
Gold onlays have been used for many years and have proved very reliable, strong and hard-wearing. Newer porcelain onlays now offer patients the option of a more natural and aesthetic finish whilst retaining the strength and durability of gold.
When properly maintained and looked after correctly, a porcelain onlay can last for over 20 years and a gold onlay for up to 30 years.
It will take at least two appointments to fit your porcelain onlay.
Firstly, any decay or old fillings in the tooth will need to be removed and the cavity will be cleaned and prepared. Impressions will be taken and used to produce your onlay, which should be ready within 2 weeks. A temporary restoration will be placed during this time.
At your next appointment, we will ensure that the size and fit of the onlay is correct and that it feels comfortable when you bite.
Only when you are completely happy will it be bonded to your tooth with a dental adhesive.
When your onlay is first fitted it may feel slightly strange until you get used to it. Be careful when biting on the tooth, particularly in the first few days. Consider sticking with a softer diet for 24 hours or eat harder foods on the opposite side of your mouth.
An onlay should be looked after in the same way as any of your other teeth to prevent the development of decay. If you experience any problems or pain contact us straight away.
Remember to attend appointments with your dentist who can check the onlay for damage on a regular basis.
