Restorative Dentistry Treatments, Inlays And Onlays

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.

Cosmetic Dentistry and Periodontal Procedures

Not even the most beautiful teeth can look attractive if healthy and pleasing-looking gums do not surround them. That's because the gums frame the teeth like a picture frame frames a picture. To have a pleasing smile, the shape, color, and texture of the gums are just as important as that of the teeth they frame. Although tooth development, periodontal disease, trauma, or tooth loss can create esthetic gum deformities, modern periodontal procedures and cosmetic dentistry can give individuals a smile to smile about.

Common Cosmetic Gum Problems

Unhealthy Gums

As a result of periodontal disease, gums may appear red, swollen, and shiny. If an individual has gingivitis or periodontitis, the gums have to be periodontally treated prior to cosmetic dentistry procedures.

"Gummy Smile"

Teeth that appear too short may be normal-sized teeth hiding under too much gum. This can be the result of normal tooth development, or the use of certain medications that may cause gums to overgrow. Either way, a crown lengthening procedure can help reveal the normal tooth structure.

Gum Recession

If the teeth appear to be too long or if the root surfaces are exposed, it may be due to gum recession. Soft tissue grafting is very successful in correcting this problem.

Uneven Gum Margins

If the gum margins appear to be higher on some teeth and lower on others, this may be due to gum recession, altered eruption, or gum defects that resulted from tooth loss. The treatment of uneven gum margins may require crown lengthening, soft tissue grafting, ridge augmentation, or a combination of these procedures.

Gum Indentations

After a tooth is lost, the bone that encased it disintegrates and the gum around it may collapse, creating an indentation where the tooth used to be. Ridge augmentation procedures can help correct this problem.

Uneven Pigmentation

Changes in the color of the gums may be part of normal gum development, or the result of scarring. Soft tissue grafts can predictably correct this problem.

Spaces In Between the Teeth

Periodontal disease can result in spaces in between the teeth that may appear like black triangles. These spaces can be very difficult to treat. They can be made less unattractive by a combination of procedures that include orthodontics (braces), crowns (caps), and/or periodontal (gum) surgery. The best way to avoid these spaces is to treat periodontal disease in its early stages and avoid the need later for cosmetic dentistry.

Missing Teeth

One or more missing teeth can be predictably replaced with the aid of dental implants. Dental implants can look and feel like natural teeth.

Changes in the appearance of the gums can occur as a result of normal tooth development, periodontal disease, trauma, or tooth loss. By working with a restorative dentist who has expertise in cosmetic dental care and through the aid of modern periodontal techniques, individuals can design a smile that is both esthetic and youthful in appearance.
