If the tooth suffers repeated decay, the appliance may need to be removed and replaced with another form of restoration. Repeated wear can degrade your restoration, and some habits can hasten the process. Your crown or onlay may suffer damage through:. Although the materials used for onlays and crowns are impervious to decay, the underlying tooth is not. If bacteria and plaque find their way below the restoration, a cavity can form.
When this happens, your dentist may need to remove the restoration to treat the tooth. Poorly designed restorations are likely to break early, which is why your dentist will take their time when taking your mold and examining your teeth. The dentist will ensure the restoration fits your teeth snugly. If the bite force is not spread evenly over the dental arch, the crown or onlay will suffer irreversible damage. Crowns or onlays made from porcelain-fused to metal contain a metal base. With time, the metal may start to reveal itself, changing the color to a darker shade.
To extend the longevity and improve the aesthetics of the crown or onlay, choose a restoration made from porcelain or zirconia. Ultimately, your dentist will examine your teeth and recommend the best option. The biggest factor will be the amount of decay. Either way, fillings are finished in a single visit. Many different materials can be used, with a range of appearances and prices, including gold, porcelain, silver amalgam, plastic, composite resin and glass ionomer. Which of these you would like can be discussed with your dentist at the Dorset Dental Implant Clinic.
Whether a repair is an inlay or an onlay depends on the extent of the damage to the tooth that it is treating- specifically, whether or not the injury or decay affects the cusp. Different types of teeth have different amounts of cusps; incisors, front teeth have one point, whereas molars, back teeth usually have 4. Inlays repair damage that does not affect the cusp of the tooth, whereas onlays are a reformation of the cusp s of the tooth or teeth. In more serious cases, where a whole tooth needs to be replaced, a crown or an implant will be used.

Please share your location to continue. The primary distinction between an onlay and an inlay is that an onlay will cover a cusp of the tooth, whereas an inlay only fills the area between the cusps. The cavity is still drilled from the tooth, and an onlay is fabricated to the exact size and shape of the space.
Conversely, a crown will cover the entire biting surface of the tooth, as well as the tooth structure above the gum line. Compared to a crown, an onlay is a less aggressive restoration when one can be performed, as less tooth structure needs to be removed in order to place the onlay. The costs are similar, but an onlay is a little cheaper than a crown. As such, an onlay is actually the preferred restoration when possible. However, the caveat here is that an onlay is more difficult to do correctly and more reliant on the skill of the dentist.
Your dentist will talk through the various options available with you and will consider a number of factors including extent of the repair, where in your mouth the filling is needed and the cost, before advising you which type of filling material is best suited for you.
