When our NYC Dentist refers to aesthetic “fillings” we are talking about one of two types of natural-looking tooth-colored restorations that are substitutes for “yesterday’s” amalgam (silver filling) and gold fillings.The simplest type of aesthetic filling is what people commonly refer to as “bonding”. This filling is performed by the New York cosmetic dentist in one single sitting and is comprised of a composite resin material (a mixture of glass and resin particles) that is placed into smaller cavities and bonded or adhered to the tooth chemically with special liquid “bonding agents”.The second type of aesthetic filling is the ceramic inlay or onlay (partial coverage restoration). These restorations are commonly performed when the tooth being restored requires a larger filling and would be otherwise compromised by a weaker material such as composite resins. Ceramic fillings are some of the most aesthetic restorations that modern dentistry can offer. They are strong, natural looking and long lasting. Properly done, they will “disappear” into the tooth and look like a perfectly healthy intact tooth.
An inlay/onlay is similar to a filling done at our NYC Dentist office, restoring normal tooth anatomy by filling in a cavity created by decay or trauma. They are a solid filling that is cemented into or onto the tooth.Certain conditions must exist for an inlay/onlay to be successful. They are used when not enough tooth structure remains to support a filling, but the tooth is not so severely damaged that it needs a crown to completely cover it. An inlay lies inside the cusp tips of the tooth. An onlay, which is similar to an inlay is extended to cover the entire chewing surface thereby protecting cusps from fracture, may be the best alternative yet. Inlays and onlays have traditionally been made of metal alloy; however, porcelain is now becoming the material of choice because of its strength. Also the porcelain restorations are tooth colored and match the remaining tooth structure.
• Silver amalgam fillings make teeth appear gray.
• Old composite fillings tend to chip and discolor over time. Inlays/Onlays are fabricated out of porcelain, the non-porous material that will never fade or discolor.
• Typically fillings can reduce the strength of the tooth by up to 50%. Inlays and onlays, however, because they are bonded directly into the tooth with special resins, can actually increase the strength of the tooth by up to 75%.
• In some cases they provide a good alternative to a crown because the inlay/onlay is a more conservative procedure. These dental restorations require removal of less tooth structure. As a result, they will sustain their natural beauty for a long time.Thanks to our advanced technology, using our CEREC computerized milling machine, Inlays and onlays can be made in our office in a single visit. The entire procedure often takes less than an hour with the best dentists in New York City instead of the usual two or three visits.
