Inlays And Onlays

Dental Inlays/Onlays

Inlays and Onlays are similar to tooth fillings as they are restorative treatments used to repair small tooth fractures, tooth decay, and other sorts of damaged surfaces of the teeth. An inlay is similar to a filling and lies within the center of a tooth. When the damaged tooth instead requires inclusion of one or several points of the tooth or even full coverage of the biting surface, this is described as an onlay. Benefits of Inlays and Onlays are that they are not likely to discolour over time as tooth-coloured resin fillings have a tendency to. Dental inlays are better at sealing teeth to keep out bacteria and are therefore preferred when the cavity is between the teeth as they are extremely stable and durable.

Dental Inlays and Onlays
To repair a damaged tooth’s biting surface or side, a dentist will often use an inlay, or an onlay. A dental inlay or onlay is an indirect filling that consists of a solid substance, such as porcelain or gold. These are sometimes seen as more conservative alternatives to crowns, which fully covers a tooth. With the material used, it is a strong and long-lasting solution to tooth decay or tooth damage.
Dental inlays and onlays have the same function as traditional dental fillings, but have a more permanent result. Whereas dental fillings are molded into place during one single dental visit, inlays and onlays need at least two visits to the dentist since the material is fabricated indirectly in a dental lab before being fitted and bonded to the tooth.


The Difference between Dental Inlays and Dental Onlays
An inlay is similar to a filling and lies within the center of a tooth, this is called an inlay. These are custom-made to fit the cavityand then cemented into place. When the damaged tooth instead require inclusion of one or several points of the tooth, or even full coverage of the biting surface, this is described as an onlay. An onlay is therefore a more extensive reconstruction, but will still conserve more of the tooth structure in comparison to a crown.

Benefits with Dental Inlays and Dental Onlays
Not likely to discolour over time as tooth-coloured resin fillings have a tendency to do.
Preserve as much healthy tooth as possible and work as an excellent alternative to a crown when the damaged area is very small.
An inlay is tailored after the tooth. While a composite filling can shrink with time, and the edges of a crown can sometimes not fit perfectly with the tooth, an inlay is tailored after all edges. This means that the tooth cleaning is easy.
Dental inlays are better at sealing teeth to keep out bacteria, therefore they are preferred when the cavity is placed between the teeth.
Extremely stable and long-lasting.
Dental inlays and onlays only protect the weak areas of the tooth, which means that a full reshaping of the tooth is not necessary.
An inlay will not stain.

Disadvantages with Dental Inlays and Dental Onlays
More costly than amalgam or composite fillings
The procedure is carried out during two appointments (instead of one for composite or amalgam filling)
