What causes discoloration of the teeth?

Teeth enamel discoloration can be caused by staining, aging, or chemical damage to teeth. Some of the more common causes of teeth discoloration are medications, coffee, tea or cigarettes. People who drink significant amounts of cola soft drinks can experience similar staining.

Aside from staining, there are other factors that can affect the color of an individual's teeth. Genetics can play a role. Some people have naturally brighter enamel than others. Disease can also be a factor and certain medications can cause a discoloration of the teeth. If you suspect that there is an underlying medical cause for your teeth discoloration, be sure to inform your cosmetic dentist.

Who is a candidate for Dental Porcelain Veneers?

Veneers, porcelain or plastic, are placed over the front teeth to change color shape of the teeth. Veneers are ideal for teeth that are too small, too big, or have uneven surfaces. It is very common for people to have imperfect teeth, either oddly shaped teeth, chipped teeth, crooked teeth, teeth with small holes in them, or an inappropriate sized tooth or teeth that have an odd appearance. Veneers solve such irregularities and create a durable and pleasing smile.

Overview of Tooth Whitening

Often an alternative to crowns, veneers are very thin pieces of specially-shaped porcelain or plastic that are glued over the front of your teeth with little or no anesthesia needed. They are the cure for teeth that are severely discolored, chipped, have small holes or pits, misshapen or crooked, or for the correction of unwanted or uneven spaces. Unlike crowns, veneers won't require the dentist to remove much of the tooth itself in most cases. It is important to ask your cosmetic dentist how much tooth will be removed. In some cases more tooth will need to be removed, which may increase the risk of trauma to the tooth. Veneers are created from an impression taken in your cosmetic dentist's office. Your custom veneer is then glued directly onto your tooth. Typically costing less than crowns, veneers won't stain, making veneers a very popular solution for many people seeking that perfect smile. Strong and very durable, veneers last from ten to fifteen years, and come in colors that will brighten dark teeth without the worry of them changing color.

How are Tooth Veneers Attached to your Tooth?

In your first appointment, it is important to initially discuss with your cosmetic dentist that you will want to "try in" your veneers with temporary cement that is the same color cement as will be used for the permanent attachment. During this "try-in" phase, be sure to look at your veneers in natural light in addition to the office light. Teeth are prepared for veneers by lightly buffing to allow for the small added thickness of the veneer. Veneers are thin like contact lenses, and will usually only need tooth reduction of 0.5mm to 1.0mm. If a drastic change is being made for the result you want, reduction may be 1.0mm to 2.0mm. A mold is taken of the teeth, from which the veneers are modeled after. Temporary veneers will be placed and worn until your permanent veneers are ready. While wearing the temporary veneers, advise your cosmetic dentist of any adjustments or changes you would like made, such as in shape or size. These changes will be translated into your permanent veneers, so good communication between you and your dentist is important in achieving your new smile.

Your dentist places the veneers with water or glycerin on the teeth to verify their perfect fit and the shade or color. The color cannot be changed after the veneers are adhered to your teeth. The tooth is then cleansed with chemicals to achieve a durable bond. Once the glue is between the veneer and your tooth, a light beam is used to harden the glue/cement.

The procedure for Lumineers is different than the above traditional porcelain veneers. Still two visits, but there is little to no preparation of the tooth and no need for temporary veneers.

There are two tooth veneers procedures available that correct discoloration of the teeth by removing the brown and yellow staining. While each work effectively, there are advantages and disadvantages to each procedure dependent upon your objectives and commitment to the processes. The type of procedures available should be discussed with your cosmetic dentist, and a they will recommend the most appropriate tooth veneers procedure for you.

Composite Veneer Procedure:

Composite (direct) veneers are usually performed in a single visit to your cosmetic dentist. The procedure is an application of a bond and enamel directly to the tooth's surface.

Porcelain Veneer Procedure:

Porcelain (indirect) veneers are a very thin porcelain material. Usually porcelain veneers require two visits and also require a dental laboratory to create the final tooth restoration piece.

Lumineer Porcelain Veneer Procedure:

Made of Cerinate porcelain, Lumineers are a new type of porcelain veneers. They are contact lens-thin, roughly .2 mm thick. Little to no tooth reduction in most cases is necessary with this type of veneer and anesthetics or numbing shots are not needed.

How much do tooth veneers cost?

Traditional Porcelain Veneers typically cost between $850 - $2,500. per tooth and require two or more visits one to two weeks apart. Veneers made of porcelain provide a greater longevity than plastic, typically ten years to fifteen years or more.

Composite Veneers cost significantly less, around $250 per tooth or more, but only last from five to seven years typically.

Lumineer Porcelain Veneers typically cost between $700. - $1,000. per tooth and also require just two visits. Lumineers are expected to last as long as traditional porcelain veneers.

Generally speaking, the price of tooth veneers and whitening increases with the number of in-office treatments required by the patient. Dental insurance does not typically cover the cost of the tooth veneers procedure. Cost will vary depending on your region, the skill level of your Cosmetic Dentist and the quality of the lab they use.

Pros and Cons of Tooth Whitening

Advantages:

People typically have a tooth whitened to improve their appearance. Teeth that are all of the same bright color are associated with beauty and a healthier lifestyle. When people have a brighter smile, they tend to smile more often and are less self-conscious.

In addition, a whiter smile tends to minimize the appearance of facial wrinkles, giving way to a more youthful and energetic appearance.

Finally, a whiter smile gives people to whom you are speaking a place to focus on and gives you a friendlier appearance.

Disadvantages:

Although tooth bleaching is very effective, there can be short term disadvantages, such as sore gums or tooth from the bleach. This disappears when bleach use is discontinued. Some individuals are more chemically sensitive. If you are one of them, inform your cosmetic dentist so that you can be tested for sensitivity to the solution.

Research indicates that tooth bleaching is completely effective in more than 78% of people. In cases of serious tooth discoloration, bleaching may not be the best choice. Veneers or crowns may be the superior choice. Bleaching is usually the first solution to try due to its lower cost.

When considering veneers a common question is how white the veneers should be. Usually, the answer is to whiten your natural teeth to either the level of whiteness you want or to the brightest they can be. Your cosmetic dentist will then have the veneers made to that color. Teeth are of course not monochromatic, so typically more than one color is used to create a very natural look. This color variation is critical in avoiding fake or artificial looking teeth. It is the internal contrast of colors that help create vitality. The internal play of light on the porcelain in the restoration helps to create this vitality. Surface texture is also very important, and helps to break up light reflections and make the crown or veneer look more natural.

There is no one standard system in the dental field to measure and determine tooth color. The most often heard about, however, is the Vita shade guide. This guide divides tooth color into four basic shade ranges:

A (reddish brown)
B (reddish yellow)
C (gray)
D (reddish gray).

In the A range there are five levels of darkness. Ranges B, C and D, each have four levels.

Not all of your teeth are the same natural color. Usually your eye teeth tend to be darker than the others, your front teeth are typically the whitest, and molars tend to be a shade between the two. The goal for everyone is to achieve their individual optimum whiteness while still looking natural.

Most dentists will show you a shade chart (like the above mentioned Vita Shade Guide) for you to pick from. Keep in mind, with a good cosmetic dentist this is merely a starting point. Other considerations when determining the color of veneers for each patient are your complexion, hair color, the color of your natural teeth and even your eye color.
