Dental inlays and dental onlays are valuable for restoring teeth that are severely decayed or worn. Typically, they are applied to the chewing surfaces on the back teeth.
What Is the Difference Between a Dental Inlay and a Dental Onlay?
In restorative dentistry, an inlay is used more like a filling for restoring normal tooth structure. It is best if the surface is small and only involves the chewing surface and surfaces between the teeth.
An onlay is similar to an inlay but treats larger areas, covering the entire chewing surface of a tooth. Dental onlays are recommended for larger tooth restorations and when chewing surfaces require long-term protection.
What Are Dental Inlays and Dental Onlays Made of?
Since both are used in areas of heavy chewing and grinding, they must be made from durable materials. They can be made from porcelain or composite resin chosen to match the color of your teeth or they can be made of a mixture of metals called an alloy. Alloys can be a mixture of metals like gold and palladium or nickel and chromium.
What Are the Restorative Dentistry Procedures for Dental Inlays and Dental Onlays?
The tooth is first prepared by removing portions of decay or damage. The remaining tooth structure is shaped in preparation for the dental inlay or dental onlay. An impression of the tooth is made along with opposing teeth and the bite. From this, a plaster model is formed that is used for a custom fit matching the contours of the tooth.
Since both dental inlays and dental onlays are custom-made, a second appointment is needed for checking the fit and cementing the inlay or onlay permanently. At that appointment, any adjustments to the bite will be made. A final polishing adds the final touch to this restorative dentistry treatment.

The color, size, and shape of your teeth all have a profound impact on your appearance. While it is often the desire of people to improve the look of their smiles, it should be the goal of aesthetic dentistry, or cosmetic dentistry, to do this while still maintaining a "natural" appearance of the teeth. This often requires addressing one or all of the above-mentioned criteria. How is it that alterations in these three characteristics enhance your smile?
Tooth color is most commonly what people see first. As you get older, your teeth get darker. The reasons for this include normal changes that occur within the tooth and repeated insults from environmental conditions (coffee or tea stains, for example). Generally, then, darker teeth are associated with older age. The easiest way that cosmetic dentistry can correct this is by teeth bleaching. But this alone may not entirely create a natural-looking appearance.
Size and shape also are major factors that define the appearance of teeth. The most common cause of changing tooth size and shape over time is tooth wear; and the most common cause of wear is tooth-to-tooth contact, or grinding. Wear on the edges of the teeth can give the appearance of aging because you do not show as much of your teeth when you smile. Another factor that affects how much of your teeth show when you smile is the loss of skin tone as you age.
This loss of tone causes your face to sag, thereby showing less of your upper teeth and more of your lower teeth. The aesthetic dentistry treatment to enable more teeth to show when you smile will depend on the cause. If the cause is due to wear of the teeth, dental veneers or dental crowns can be used to regain the lost length and fill out the smile. On the other hand, this may not have a significant effect if the cause is due to the loss of skin tone associated with age. If this is the case, plastic surgery may be indicated as part of the treatment.
Wear on teeth also will make the edges of the front teeth very flat. As this occurs, the edges of the front teeth will form a straight line rather than the more youthful appearance when the two front teeth are slightly longer than the teeth next to them. Also, as they wear, the proportion of length to width will be altered. Teeth will start to appear more square in their shape rather than rectangular.
Basically, any treatment that counteracts the above-mentioned appearance changes has the ability to enhance the appearance of your teeth and smile. The aesthetic dentistry treatment can vary from teeth bleaching to dental crowns or dental veneers. Depending on the severity, other forms of treatment such as braces and gum surgery also may be indicated to enhance the appearance and function of your teeth. It is important to remember that all areas need to be addressed. If treatment for teeth that are worn and dark only involves teeth bleaching, the final result will be whiter teeth that are still worn and short. The teeth will not appear natural, as there will be a conflict between white teeth (youthful) and worn teeth (aged) that do not work together. Instead, it is necessary to correct the color, size, and shape to create a more natural appearance.
