Porcelain Crowns (Caps)
Porcelain Fixed Bridges
Quick and Effective Smile Makeovers
Dental bonding is a method of restoring teeth with a natural looking finish. A coloured substance (composite resin) is matched precisely to your tooth structure. It is used as white fillings and for cosmetic improvements to improve the function and appearance of teeth. The superior techniques and materials used to today provide a beautiful improvement to your smile in one appointment.
Teeth Whitening / Bleaching
Tooth bleaching, also called tooth whitening, is a procedure designed to change the extrinsic colour of the teeth. Traditionally a bleaching gel is applied to the teeth using a custom fabricated tray. Oxidizing agent within the gel, such as hydrogen peroxide and carbamide peroxide, lighten teeth colour by penetrating microscopic porosities in the outer enamel layer. At this point, food, bacteria and tobacco pigments are oxidized.
There are 2 main types of professional bleaching:
- Professionally monitored home bleaching. This involves the fabrication of a custom made rubber tray to hold bleaching gel against the teeth. The patient will wear the trays for 60-90 minutes per day for a 2 week period. Whitening occurs at a constant, even safe manner.
- In office bleaching. This process involves using a light source (such as halogen, LED or plasma) to accelerate the action of the hydrogen peroxide gel. Typically a resin based, light hardened barrier is applied to the soft tissue around the teeth for protection. Treatment time is typically one hour. A higher concentration peroxide gel is required verses the home bleaching method.
Over the counter bleaching involves using strips containing low concentration H2O2 placed over the front teeth, or self made trays to contain bleaching material. Whitening products for home use also include gels, chewing gum, rinses and toothpastes. Whitening tooth pastes contain silica, aluminum oxide, calcium carbonate or phosphate in order to remove stains by physically scrubbing them off the surface.
An individual should consult their dentist prior to a bleaching procedure. A thorough medical and dental history is needed to screen for allergies. An exam is needed of hard and soft tissues to assess current restorations.
Bleaching is not recommended for children under the age of 16 as larger pulp tissue within the teeth can be irritated. Pregnant and lactating women should hold off using bleaching materials.
A dental bridge is an option to replace missing teeth. They are cemented or bonded to the teeth adjacent to the open space. When a tooth is missing, the remaining teeth may shift or rotate and the opposing tooth or teeth may overerupt. This can result in a malocclusion (bad bite), create an unaesthetic smile, exacerbate periodontal (“gum”) disease and possibly lead to a TMD (jaw joint) problem.
Porcelain or ceramic crowns are suited to protect or “cap” damaged teeth. Crowns are used to protect teeth with large fillings where insufficient natural tooth structure remains. It can restore a weakened or fractured tooth and is usually indicated after root canal therapy is complete. Crowns can be placed on top of dental implants providing a tooth with a natural shape and function. Alternative materials include gold, metal allows and acrylic.
Veneers are a thin layers of either porcelain or composite resin used to cover a tooth surface. The maim purpose is to improve esthetics or to protect a chipped tooth.
There are many indications for veneers:
- Close spaces between front teeth.
- Provide a more vibrant, youthful appearance to worn aged teeth.
- Correct the alignment of malpositioned teeth.
- Provide a whiter more uniform colour to the front teeth.
- Direct composite resin veneers can be sculpted directly in the mouth in a single visit.
Indirect composite resin or porcelain veneers require a master ceramist to fabricate the restoration in a dental laboratory. These are the most esthetic veneers.
