By being bonded to the tooth, the filling pulls inward on the tooth’s periphery, holding it together. This is in contrast to metal fillings, which exert outward pressure and will eventually fracture the tooth.
Tooth-colored fillings also benefit you by requiring less healthy tooth tissue to be removed. When a metal filling is placed, the cavity must be shaped to hold it in and must be given a ridged surface, requiring removal of some healthy tissue. Bonding eliminates that necessity.
Porcelain fillings offer:
Dr. Marshall has been a practicing cosmetic dentist since 1998 and has received recognition for her studies and work at LVI (Las Vegas Institute for Advanced Dental Studies) and other well-known educational institutions. She is trained to work with porcelain and to design excellent dental restorations.
Dental inlays and dental onlays are restorations for teeth with decay, cracks, or large chips broken out of them. Whether Dr. Lindsey Marshall does an inlay or an onlay depends on the size of the damaged area.
Dental inlays and onlays are made from porcelain matched to your natural teeth. Inlays and onlays are often used to replace existing mercury fillings. Porcelain is more structurally sound than metal fillings, since the ceramic is bonded to the tooth rather than just packed into it tightly. Inlays and onlays can prevent bacteria from spreading between the restoration and the tooth and causing further decay.
Tooth-colored fillings do not have as much of a pearly sheen as porcelain fillings, although they are white and matched to your natural teeth. Tooth-colored fillings are also not quite as durable as porcelain fillings. If you need a filling on a front surface of a front tooth, you might consider porcelain instead of composite.
A word of caution if you are considering a teeth whitening treatment: white composite will not be affected by the bleaching agent. Have the whitening treatment done before your new fillings are placed. This way, Dr. Marshall can match the fillings to your new tooth color.
Porcelain fillings provide a natural appearance that closely resembles your own teeth. Dental porcelain has the same translucent appearance as natural tooth enamel. Once the porcelain filling is bonded to your tooth, it becomes extremely durable and resistant to wear and tear. Cosmetic dentist Dr. Lindsey Marshall has extensive experience and hands-on skill using CEREC technology to create porcelain fillings and porcelain crowns.
Porcelain fillings are a much safer alternative to the old metal amalgam fillings. The porcelain is so similar in appearance to your natural teeth that nobody will know you have a filling. Because the porcelain filling is bonded to the tooth, it preserves and strengthens the tooth, rather than weakening and eventually fracturing it, as a metal filling does.
You will not always have to come for a second visit. The CEREC system allows us to bypass the dental laboratory so you won’t have to wait while your porcelain filling gets made. You also won’t need a temporary filling. With CEREC, you come for one visit only and leave with an invisible and comfortable restoration done with microscopic accuracy.
Because of the controversy over dental use of mercury and metal and the possible threat to your health, we have chosen to make our office metal-free and mercury-free. Instead of metal amalgam and gold, we use tooth-colored composite and dental porcelain. Both of these materials are matched in shade to your natural teeth, and they offer greater safety and visual appeal than any metal restorations.
Whether or not you should replace your metal fillings is an individual choice. If they are old and beginning to discolor the tooth or threatening to crack it, you probably should consider having them replaced with porcelain fillings or tooth-colored fillings.
Some studies have found no adverse effects from amalgam fillings, but others have found a correlation between the number and size of metal fillings in the teeth and the levels of mercury in body tissues. The International Academy of Oral Medicine and Toxicology (IAOMT) opposes the use of amalgam, although the American Dental Association still asserts that mercury in fillings is safe.
Use of amalgam has been declining steadily in the U.S. as the public has become more aware of the potential threat to general health.
To protect you from any unnecessary health risk, Dr. Marshall has chosen not to offer metal fillings. She can replace your old metal fillings with either tooth-colored fillings using dental composite or porcelain fillings, if you would like to have that done. Safety precautions would be taken against mercury vapor and particles.
Metal fillings look unattractive, marring your smile with their dark gray color. Some people find they have an allergy to one or more of the metals in the amalgam.
The first step is removal of bacteria from the tooth, along with debris and the decayed tissue they have created. When the tooth is entirely clean, it is photographed for input into our CEREC system.
Dr. Marshall will use the CAD-CAM software that is part of CEREC technology to design your inlay or onlay. She will choose a small block of dental porcelain closely matching your teeth, and the CEREC mill will sculpt it to the exact size and dimensions she has input.
Your porcelain dental inlay or onlay will be temporarily fitted so Dr. Marshall can make sure your bite is unaffected. She will ask you how it feels and will test your bite, making small modifications to the restoration if necessary until you are both pleased. Then she will bond it permanently to the tooth, making it a part of that tooth. It will not be visible as a dental restoration, except to a cosmetic dentist.
Porcelain onlays are a valuable focus of cosmetic dentistry ... Click to go to the page of cosmetic services ... because they can rejuvenate a badly damaged tooth. Onlays fill a gap in the restoration continuum between a filling and a crown. By holding the outside surface to the inside of the tooth, the restoration prolongs the tooth’s life and gives it new chewing or biting strength.
