lastic mixture filled with glass. Composites are not only used to resto
re decayed areas, but are also used for cosmetic improvements of the smile by changing the color of the teeth or reshaping disfigured teeth.
In order to bond a filling material to your tooth, it is first necessary to remove decay, prepare the tooth and then to condition the enamel and dentin. Once conditioned, a thin resin is applied which bonds to the etched surface. The bond strength of these fillings is incredible.
Following preparation, the dentist places the composite in layers, using a light specialized to harden each layer. When the process is finished, the dentist will shape the composite to fit the tooth. The dentist then polishes the composite to prevent staining and early wear. Bonding increases the strength of these restorations far beyond those of only a short time ago.
Composites bond to the tooth to support the remaining tooth structure, which helps to prevent breakage and insulate the tooth from excessive temperature changes. After receiving a composite, a patient may experience post-operative sensitivity.Also, the shade of the composite can change slightly if the patient drinks tea, coffee or other staining foods. The dentist can put a clear plastic coating over the composite to prevent the color from changing if a patient is particularly concerned about tooth color.
Composites tend to wear out in larger cavities, although they hold up well in small cavities. After placement, you may chew right away. The light instantly hardens these fillings. Your teeth may experience some degree of temperature sensitivity for a few days to a week. If it does not disappear within that period of time, contact your dentist.
These light cured composites are extremely cosmetic and most often bonded into place in one appointment. They are often referred to as “bonding.” Studies have shown that composites last 7-10 years.
In the past, teeth were most commonly repaired with silicate or acrylic restorations. Thanks to advances in modern dental materials and techniques, teeth can be restored with a more aesthetic and natural appearance. There are different types of cosmetic fillings currently available. The type used will depend on the location of the tooth and the amount of tooth structure that needs to be repaired.
White Composites – Back Teeth
A composite resin is a tooth-colored plastic mixture filled with glass. In the past, dental composites were confined to the front teeth because they were not strong enough to withstand the pressure and wear generated by the back teeth.
Following preparation, the dentist places the composite in layers, using a light specialized to harden each layer. When the process is finished, the dentist will shape the composite to fit the tooth. The dentist then polishes the composite to prevent staining and early wear. It takes the dentist about 10-20 minutes longer to place a composite than a silver filling. Placement time depends on the size and location of the cavity and the larger the size, the longer it will take.
The average cost of posterior composites is about one-and-a-half to two times the price of a silver filling. Most dental insurance plans cover the cost of the composite up to the price of a silver filling, with the patient paying the difference. As composites continue to improve, insurance companies are more likely to increase their coverage of composites.
Esthetics are one of the main advantages, since dentists can blend shades to create a color nearly identical to that of the actual tooth. Composites bond to the tooth to support the remaining tooth structure, which helps to prevent breakage, minimize leakage and insulate the tooth from excessive temperature changes.
After receiving a composite, a patient may experience post-operative sensitivity. Also, the shade of the composite can change slightly if the patient drinks tea, coffee or other staining foods. Composites tend to wear out sooner than silver fillings in larger cavities, although they hold up as well in small cavities. Studies have shown that composites last 7-10 years, which is comparable to silver fillings except in very large restorations, where silver fillings last longer than composites.
In the past, teeth were most commonly repaired with amalgam (silver) fillings or gold restorations. Thanks to advances in modern dental materials and techniques, teeth can be restored with a more aesthetic and natural appearance. There are different types of cosmetic fillings currently available. The type used will depend on the location of the tooth and the amount of tooth structure that needs to be repaired.
The other type of “white fillings” are called Composite or Porcelain Inlays and Onlays. These fillings are usually placed in back teeth when esthetics is of utmost concern. In order to increase their strength and longevity, they are fabricated in the laboratory and then bonded into position in the office. This is a two visit procedure rather than the one visit required to place a direct composite filling. However, when it comes to strength and cosmetics, the extra time and expense is well worth it! I hope that you now understand a little bit more about white fillings.
Porcelain Veneers
Porcelain veneers are thin shells of ceramic material, which are bonded to the front of teeth. They can be the ideal choice for improving the appearance of the front teeth. Porcelain veneers are placed to mask discolorations, to close spaces, to brighten teeth, to straighten teeth, and to repair broken tooth structure. Highly resistant to permanent staining from coffee, tea, or even cigarette smoking, the wafer-thin porcelain veneers can achieve a tenacious bond to the tooth, resulting in an esthetically pleasing naturalness that is unsurpassed by other restorative options.
Porcelain veneers are an excellent alternative to crowns or fillings in many situations. They provide a conservative approach to changing a tooth’s color, size, shape or position. Porcelain veneers can mask undesirable defects, such as teeth stained by tetracycline, by an injury, or as a result of a root canal procedure, and are ideal for masking discolored fillings in front teeth. Patients with gaps between their front teeth or teeth that are chipped or worn may consider porcelain veneers. Generally, veneers will last for many years, and the technique has shown remarkable longevity when properly performed.
Patients may need several appointments for the entire procedure including diagnosis and treatment planning, preparation, and bonding. It’s critical that you take an active role in the smile design. Spend time in the decision-making and planning of the smile. Understand the corrective limitations of the procedure to correct tooth defects, color or position.
The preparation appointment will take from one to several hours. To prepare the teeth for the porcelain veneers, the teeth are lightly reduced to allow for the small added thickness of the veneer. Usually, about a half a millimeter of the tooth is removed, which may require a local anesthetic. At this appointment, a mold is taken of the teeth, which is sent to the laboratory for the fabrication of the veneers. This can take about one to three weeks. If the teeth are too unsightly a temporary veneer can be placed, at an additional cost.
Bonding of veneers will take about one or two hours. First, the dentist places the veneers with water or glycerine on the teeth to check their fit and get a sense of the shade or color.While the veneers are resting on your teeth, view the esthetic results, and pay particular attention to the color.At this point, the color of the veneers can still be adjusted with the shade of the cement to be used. The color cannot be altered after veneers are cemented. To apply the veneer, the tooth is cleansed with specific chemicals to achieve a bond. Once a special cement is sandwiched between the veneer and tooth, a visible light beam initiates the release of a catalyst to harden the cement.
All porcelain restorations are called veneers when they cover only the front of teeth. They are crowns w
hen they cover all surfaces of teeth. Restorations are three quarter crowns when they do not cover the surface of teeth toward the tongue. It is often difficult to distinguish one type of restoration from another and therefore, it is easier to call them bonded porcelain restorations.
Crowns – Front and Back Teeth
Crowns are used to support a tooth when there isn’t enough of the tooth remaining, protect weak teeth from fracturing, restore fractured teeth, or cover badly shaped or discolored teeth. A crown is a restoration that covers a tooth like a thimble to restore it to its normal shape and size while improving strength and appearance of a tooth. Crowns are necessary when a tooth is generally broken down and fillings won’t solve the problem. If a tooth is cracked, a crown holds the tooth together to seal the cracks so the damage doesn’t get worse.
To prepare the tooth for a crown, it is reduced so the crown can fit over it. An impression of teeth and gums is made and sent to the lab for the crown fabrication. A temporary crown is fitted over the tooth until the permanent crown is made. On the next visit, the dentist removes the temporary crown and cements the permanent crown onto the tooth.
Crowns require more tooth structure removal, hence, they cover more of the tooth than veneers. Crowns are customarily indicated for teeth that have sustained significant loss of structure. Crowns are made from various materials including plastics, porcelains and metals or combinations of these.
The dentist’s main goal is to create crowns that look like natural teeth. To achieve a certain look, a number of factors are considered, such as the color, bite, shape, and length of your natural teeth. When the procedure is complete, your teeth will not only be stronger, but they may be more attractive.
Crowns should last approximately 12 years. However, with good oral hygiene and supervision most crowns will last for a much longer period of time. Some damaging habits like grinding your teeth, chewing ice, or fingernail biting may cause this period of time to decrease significantly.
To prevent damaging or fracturing the crowns, avoid chewing hard foods, ice or other hard objects. You also want to avoid teeth grinding. Besides visiting your dentist and brushing twice a day, cleaning between your teeth is vital with crowns. Floss is important to remove plaque from the crown area where the gum meets the tooth. Plaque in that area can cause dental decay and gum disease.
Replacing Missing Teeth
Fixed Bridges and Implants
A fixed bridge replaces missing teeth. Teeth on either side of the space are prepared for crowns. Crowns are joined together so crowns on either side can support the missing teeth in the middle.
Implants, usually made of titanium metal similar to that used in pins to join fractured bones, are permanent replacements for missing teeth. Part of the implant acts as the root of a tooth and supports a section that extends above the gums. Replacement teeth may be permanently fixed to the sections above the gums, like fixed bridges, or can be removable similar to overdentures.
Partial Dentures
Partial dentures replace missing teeth supported by gums and remaining teeth. Removable partial dentures usually consist of replacement teeth attached to pink or gum-colored resin bases, which are connected by a metal framework. Removable partial dentures attach to your natural teeth with rests, guide planes and metal clasps. The metal clasps often shows when smiling. A denture helps you to properly chew food, improve speech and prevent a sagging face by providing support for lips and cheeks.A full denture is held in by suction so function is compromised.
An overdenture is a denture that uses precision dental attachments to hold the denture down. The overdenture attachment can be placed in tooth roots that have been saved, or placed onto dental implants that have been placed to receive them. When proper smile design principals are applied to dentures, they can look very natural. Indeed, most denture patients want more imperfections in their denture teeth so they look more natural.
Full Dentures
There is a substantial difference between full dentures and your own teeth since it is only suction which holds a full denture in place.
Dentures may move or come loose when the tongue, lips, cheeks and muscles push against it. Good impressions provide an accurate fit and seal around the edges. Retention and stabilization can be aided by the shape of bone and firmness of gums which make it more difficult to break the suction.
It is difficult to predict how a patient will adapt to dentures.A stable, retentive denture increases success, but people must adapt psychologically and learn techniques of functioning with a denture. Speech patterns must be relearned and chewing efficiency may be dramatically reduced. For these reasons, full dentures are the last resort of dentistry.
There are two alternatives to full dentures: overdentures and implants. Occasionally weak teeth can be used to stabilize dentures. Teeth reduced in height are much stronger because forces are closer to the gums reducing the force generated on their roots.
Overdentures are dentures which fit over weak teeth reduced in height after root canals. In addition, precision attachments can be placed in these teeth and dentures for added retention. Retaining roots will also help maintain bone height which might recede if roots were not there.
