What are Inlays & Onlays?
Dental inlays and onlays are a medium between dental crowns and fillings. They are made from pure porcelain to fit the shape of a cavities exact shape and size. They are implicated on teeth at the back of the mouth that has suffered a moderate level of decay. They are perfect for teeth that have undergone some fracturing; more serious damage will probably be resolved with a dental crow. Unlike a filling they do not apply any pressure to the walls of the cavity. The ensures the cavity/ damage does not get any bigger which is often the case with a filling.
The two main types of inlays and onlays are made from resin or porcelain. It is also not uncommon to see gold versions. However, the inlays and onlays are often more appealing as porcelain and resin as they can be coloured to look natural. This often makes dental inlays and onlays a popular choice for those wishing to replace unattractive fillings that are made from metal.
This type of dental product is bonded into place around the cusps. Onlays are used to cover one cusp or more, whereas dental inlays tend to be used more as a filling between the cusps. This area is vulnerable to damage due to chewing and so is often prone to fracturing.
