See what braces, crowns, veneers, teeth whitening, bridges, implants, gum reshaping — or even a complete dental makeover — can do for your smile.



dentalbonding

Dental Bonding

Bonding is a procedure in which a tooth-colored resin is applied and hardened with a special light, ultimately “bonding” the material to the tooth to improve a person’s smile. Among the easiest and least expensive of cosmetic dental procedures, bonding can repair chipped or cracked teeth, close gaps, change the shape of teeth, or be used as a cosmetic alternative to silver amalgam fillings.



veneers

Veneers

Veneers are wafer-thin, custom-made shells that cover the front surface of teeth. Bonded to the front of the teeth, changing their color, shape, size or length, veneers can be made from porcelain or resin composite. Veneers offer a conservative approach to changing a tooth’s color or shape compared to crowns, but the process is not reversible.


crowns

Crowns

A crown is a tooth-shaped “cap” that’s placed over a weak or damaged tooth to improve its shape, size, strength, or appearance. Most crowns last five to 15 years and can be made of metal, porcelain fused to metal, resin, or ceramic. Before a crown is seated, the existing tooth is filed down; then the crown is cemented over it, fully encasing the tooth. Onlays and three-quarter crowns cover the underlying tooth to a lesser extent.

Enamel Shaping

Enamel shaping or contouring is a quick and painless process of shaping natural teeth to improve their appearance. It is generally used to correct small imperfections such as uneven teeth or teeth that are slightly overcrowded. Results can be seen immediately. Enamel shaping is often combined with whitening, veneers, or bonding.


braces

Orthodontics (Braces)

Braces can correct crooked or misaligned teeth, and can improve the health and appearance of anyone’s smile — adult or child. Braces work by applying steady pressure over time to slowly move teeth into alignment. As the teeth move, the bony tooth socket changes shape as pressure is applied.

Types of Braces

While metal braces are still used, braces can be as inconspicuous as you like. Brackets — the part that attach to each tooth — can be clear, tooth-colored, or multi-colored. They can even be attached to the back of the tooth so they are out of view. There are even “invisible” braces which use a series of clear, plastic molds to gradually move the teeth into alignment.


teethwhitening

Teeth Whitening

Who doesn’t like a bright smile? An assortment of teeth-whitening systems is available, including toothpastes, over-the-counter gels, strips and trays, and whitening agents obtained from a dentist. But whitening isn’t for everyone. It’s ideal for people who have healthy, unrestored teeth and gums. Individuals with yellow tones to their teeth — as opposed to gray tones — respond best. Talk to your dentist to find out if whitening is right for you.

In most cases, the natural colour of teeth is within a range of light greyish-yellow shades. Teeth naturally darken with age and their appearance can be affected by the accumulation of surface stains acquired from the use of tobacco products and the consumption of certain foods or drinks.

In addition, the perception of the colour of teeth is severely affected by skin tone and make-up. Independent of the real colour of their teeth, people with darker skin or who use dark makeup will look like they have brighter teeth.

Although teeth are not naturally meant to be completely white, many Canadians want a brighter smile. Responding to this desire, a wide range of “whitening” options has become available to consumers. These products fall into two main categories: surface whiteners and bleaches.

It should be noted that claims related to tooth whitening are seen as cosmetic in nature by Health Canada. These claims must be accurate, so as not to mislead the public. However, the regulator tolerates some puffery or exaggeration. As a consequence, the results of whitening treatment may not be as convincing as consumers originally expected.

Surface Whiteners

These products use special abrasives to improve the product’s ability to remove surface stains. Most products in this category are either toothpastes or chewing gums. Because the special abrasives in these whitening products are often only finer versions of what is used in regular toothpastes, they are unlikely to cause excessive tooth wear. However, the effectiveness of these products is limited to surface stains and should not be used as a substitute for professional cleaning.

Bleaches

Most bleaching products are peroxide-based and are actually capable of altering the colours of the tooth itself. However, not all tooth discolourations respond to tooth-bleaching treatments. Individuals contemplating tooth-bleaching should consult with a dentist to determine the cause of the tooth discolouration and to determine whether a bleaching treatment will have the desired result. This step is especially important for patients with fillings, root canal treatments, crowns and/or with extremely dark stains on the anterior teeth.

A number of different bleaching techniques and products are available to patients. Your dentist will use one of these two methods to whiten your teeth:

Vital bleaching is done on “living” teeth and can be used to whiten your teeth if they have become stained by food or tobacco, or if they have become dark with age.

Non-vital bleaching is bleaching done on teeth that are no longer “alive.” If your tooth has changed colour because of a root canal, non-vital bleaching can lighten your tooth from the inside out.

There are three methods for bleaching teeth. The method that will work best for you depends on the number of teeth that need to be bleached, and on how badly they are stained (or discoloured).

Your dentist may suggest:

Putting a special bleach on your stained teeth and using heat (or heat and light) to start the bleaching action; or

Wearing a custom-made mouthguard filled with a special bleach for part of each day; or

Brushing with a special bleach mixed in toothpaste.

Bleaching should be done only under a dentist’s care. Tooth-bleaching under controlled dental office conditions may be safe and effective, but the new in-office vital tooth-bleaching techniques, particularly those using laser and lights, have undergone little scientific assessment.

Home-use tooth-bleaching systems are available to the general public, either from a dentist or from various retail outlets. Clinical studies support the safety and effectiveness of home-use bleaching gels when used appropriately. Tooth sensitivity and irritation to soft tissues can occur during bleaching treatment, but these effects are transient. Yet the effects of long-term tooth-bleaching are unknown and need to be researched, especially since the effect is not permanent and many individuals end up undergoing periodic bleaching treatments.

compositefillings

Composite Fillings

Existing fillings sometimes need to be replaced due to wear, chipping, or cracking. Many people use this opportunity to replace their silver amalgam fillings with natural, tooth-colored composites. Their reasons may be aesthetic, or concern over the safety of amalgam fillings, which contain mercury. Composite fillings tend to wear out sooner than silver fillings in larger cavities, although they hold up as well in small cavities.

gumreshaping

Gum Reshaping

Gum reshaping can improve a “gummy” smile in which teeth appear too short, or where the gum line appears uneven. A small amount of gum tissue — and excess bone tissue if necessary — is removed and contoured to expose more of the teeth. This procedure can be done to one tooth to even the gum line, or to several teeth to expose a natural, broad smile.

implants

Implants

Millions of people suffer tooth loss, mostly due to tooth decay, gum disease, or injury. Dental implants — replacement tooth roots which are made of titanium (shown at far left) — provide a strong foundation for the attachment of fixed or removable artificial teeth (crowns). Instead of individual crowns, some patients may have attachments on their implant that support a removable denture.

dentures

Dentures

A denture is a removable replacement for missing teeth and surrounding tissue. There are two types of dentures — complete and partial. Complete dentures are used when all the teeth are missing, while partial dentures are used when some of the natural teeth remain.

bridges

Bridges (fixed partial dentures)

A fixed (permanent) bridge replaces one or more teeth by placing crowns on the teeth either side of the gap, and attaching artificial teeth to them. The “bridge” is then cemented into place. A cantilever bridge is used when there are teeth on only one side of the open space. Maryland bonded bridges have porcelain teeth supported by a framework.

gumgafts

Gum Grafts

Tooth roots that are exposed due to gum recession may be sensitive to hot and cold foods or liquids, and they make teeth appear long. Gum recession can put you at risk of developing a cavity on the tooth root, and may lead to bone loss, eventually resulting in tooth loss. Soft tissue grafts, which move healthy gum tissue from one part of the mouth to another, can stop gum recession and bone loss and improve the esthetics of the gum line.

smilemakeovers

Smile Makeovers

A combination of dental techniques can be used to achieve a great smile. Here, porcelain veneers and crowns correct crooked teeth, an uneven gum line, and other chipped, worn, and discolored dentistry. While cosmetic dentists can make a dramatic difference in a person’s smile and overall oral health, the work must be carefully planned — though for many the elaborate and costly production is worth it in the end.
