Bridges are natural-looking dental appliances that can replace a section of missing teeth. Because they are custom-made, bridges are barely noticeable and can restore the natural contour of teeth as well as the proper bite relationship between upper and lower teeth.
Bridges are sometimes referred to as fixed partial dentures, because they are semi-permanent and are bonded to existing teeth or implants. There are several types of fixed dental bridges (cannot be removed), including conventional fixed bridges, cantilever bridges and resin-bonded bridges. Unlike a removable bridge, which you can take out and clean, your dentist can only remove a fixed bridge.
Porcelain, gold alloys or combinations of materials are usually used to make bridge appliances.
Appliances called implant bridges are attached to an area below the gum tissue, or the bone.
Crowns (Same Day Crowns)
Crowns are ceramic porcelain, placed on the top of a tooth. Our office can Custom your crowns and Seat the same day when requested. However, upon occasion due to your bite or oral health the crown and bridges may need to be sent to the lab for a custom design and fitting by our certified technician.
Crowns are typically used to restore a tooth's function and appearance following a restorative procedure such as a root canal. When decay in a tooth has become so advanced that large portions of the tooth must be removed, crowns are often used to restore the tooth.
Crowns are also used to attach bridges, cover implants, prevent a cracked tooth from becoming worse, or an existing filling is in jeopardy of becoming loose or dislocated. Crowns also serve an aesthetic use, and are applied when a discolored or stained tooth needs to be restored to its natural appearance.
A tooth must usually be reduced in size to accommodate a crown. Scanned for a same day crown or an impression is made from the existing tooth to create a custom-designed crown. The impression is sent to a special lab, which manufactures a custom-designed crown. If your crown is sent to the lab you will have a custom temporary crown place until the permanent crown is ready. Permanent crowns are cemented in place after about 2 weeks.
Crowns are sometimes confused with veneers, but they are quite different. Veneers are typically applied only to relatively small areas.
Caring For Your Crowns
With proper care, a good quality crown could last up to five years or longer. It is very important to floss in the area of the crown to avoid excess plaque or collection of debris around the restoration. It is highly recommended that you maintain your cleanings at the suggested intervals give by your Dr. Weatherall and/or her Hygienist.
Certain behaviors such as jaw clenching or bruxism (teeth grinding) significantly shorten the life of a crown. Moreover, eating brittle foods, ice or hard candy can compromise the adhesion of the crown, or even damage the crown. This is a natural way your body tries to heal itself as often as you sleep, during stressful times or a change in medication. Dr. Weatherall may treatment plan an Occlusal Guard/Night Guard to diminish the damage bruxing can cause.
Dry Mouth can cause area of infection, bone loss and rampant decay. Your maintenance visits will help make the determination if you are have oral and/or medical issues cause your crowns to fail during these appointment. Dr. Weatherall may suggest that you visit your physician and/or offer a rinse or tooth paste that could help bring moisture and slow down the process of further damage.
Teeth that are badly stained, shaped or crooked may be improved by a veneer placed on the surface of the affected teeth.
Veneers are thin pieces of porcelain or plastic cemented over the front of your teeth to change their color or shape. Veneers are used on teeth with uneven surfaces or are chipped, discolored, oddly shaped, unevenly spaced or crooked. Little or no anesthesia is needed. Veneers have a longer life expectancy and color stability than bonding, and highly resist permanent staining from coffee, tea, or even cigarette smoking.
Veneers are usually made by a dental lab technician working from a model provided by your dentist. Veneers are usually irreversible because it`s necessary to remove a small amount of enamel from your teeth to accommodate the shell.
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.
Typically, veneers entail at least three appointments: diagnosis and treatment planning, preparation, and bonding.
During the tooth preparation visit, usually lasting one to two hours, the teeth are lightly buffed 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. During the same visit, a mold is taken of the teeth, and sent to the laboratory for the fabrication of the veneers.
During the final "bonding" visit, also about one or two hours, the veneers are placed on the tooth surface with water or glycerin on the teeth to check their fit and get a sense of the shade or color. While the veneers are resting on your teeth, they can be adjusted with various shades of cement to match the color of your teeth. 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, or laser, causes a catalyst to be released, hardening the cement.
During a two-week period of adjustment that follows, you may notice the change of size and shape in your teeth. It is important to brush and floss daily. After one or two weeks, you`ll return for a follow-up appointment. Porcelain veneers are reasonable facsimiles of natural teeth, not perfect replacements. It`s not uncommon to see slight variations in the color of porcelain veneers upon close inspection, as this occurs even in natural teeth.
For certain patients no preparation of the teeth may be necessary. Please see our specialties page for more information.
