Dental professionals sometimes use specialized words, and you may not be clear about exactly what we mean. Test yourself on some of the specialized vocabulary concerning tooth whitening. How many of the following can you define correctly?
A method of making yellow, discolored teeth whiter. It is relatively inexpensive and safe, with few side effects.
2. External or extrinsic staining and whitening?
Extrinsic staining mainly results from diet and smoking. For example, foods such as red wine, coffee and tea can produce extrinsic stain. Teeth with these stains are bleached by placing whitening substance in direct contact with the living tooth surface.
3. Internal or intrinsic staining and whitening?
Intrinsic tooth discoloration is caused by changes in the structure of enamel, dentin, or pulp tissue deep within the root of the tooth. When the discoloration originates with the pulp tissue, root canal treatment may be needed to whiten the tooth from the inside.
4. Chromogenic material?
Color generating material that may get incorporated into the tooth's substance. It can be a result of wear and aging, or can be caused by inflammation within the tooth's pulp.
5. Carbamide Peroxide?
A bleaching agent discovered in the 1960s and frequently used for tooth whitening. When used, carbamide peroxide breaks into its component parts, hydrogen peroxide and urea, which bleach the colored organic molecules that have been incorporated between the crystals of the tooth's enamel.
6. Power Bleaching?
This technique is used for severely stained tooth. It uses a highly concentrated peroxide (35 to 45 percent) solution placed directly on the teeth, often activated by a heat or light source. This must be done in our office.
An antibiotic used to fight bacterial infections. It can result in tooth staining when taken by children whose teeth are still developing.
8. Rubber Dam?
Use of strong bleaching solutions requires protection for the gums and other sensitive tissues in your mouth. This is done using a rubber dam, a barrier to prevent the material from reaching your gums and the skin inside your mouth. Silicone and protective gels may also be used.
9. Whitening Strips?
Strips resembling band-aids that you can use in your home to whiten your teeth. They generally contain a solution of 10 percent or less carbamide peroxide gel. When using them, be sure to read the directions and follow them strictly to avoid injury or irritation.
10. Fade Rate?
The effects of bleaching may fade over time, from six months to two years. This is called the fade rate. It can be slowed down by avoiding habits such as smoking, along with food or drink that causes tooth staining.
Getting a new crown for a front tooth is a standard procedure performed in thousands of dental offices around the country. But dental patients are sometimes surprised to find that the price of this routine treatment can vary by a substantial amount. What accounts for the difference? The answer tells us a lot about how crowns are made, and the value of aesthetics in dentistry.
Crowns may be made of several different materials. Gold, the most traditional restoration material, makes for a time-tested, functional and durable crown, lasting as long as 50 years. Gold is a precious (and expensive) metal, but considered over the lifetime of the restoration, it's an economical choice. Yet, even for back teeth, it's losing out in popularity to more aesthetically pleasing alternatives.
Porcelain-fused-to-metal (PFM) crowns and all-porcelain crowns replicate the look of natural teeth more accurately. The kind of porcelain used in restorations must have special strengtheners added, which enable it to stand up to wear and tear in the mouth. There are different porcelain materials used in dental restoration, each with a different look, quality and longevity. There are also new, high-tech ceramic materials. Each one has advantages and drawbacks, and each one's cost is different.
Besides the material, another large part of a crown's cost is the custom-fabrication of every piece. Since it must match the other teeth in form and function — and often in looks as well — every crown must be made to an individual's exact requirements. This includes the tooth's exact size and shape, its spacing, and (often) its particular color.
Making this happen is a multi-step process. First, a dentist carefully prepares a model of the affected tooth and its neighbors. Then, the fabrication work is normally performed by a highly skilled laboratory technician, at the dentist's direction. Finally, the dentist prepares the tooth for the restoration, performs final adjustments, and attaches the finished crown. When it's done, the restored tooth can be difficult to tell apart from any other.
The level of craftsmanship involved at the dental laboratory can vary — and along with it, the price. Dentists may even choose different technicians based on the quality level they're striving for. All of these factors affect the final cost of the crown, and its value to the patient.
It has been said that beauty is in the eye of the beholder, and this is certainly true in the case of dental restorations. The choice of a “best” crown is different for every person — more than one alternative may be available, and each comes with its own price. If you have more questions about your options for a crown restoration, don't hesitate to ask us!

We all know that dentistry can do amazing things these days to give you the smile you've always dreamed of. With the latest cosmetic and restorative dental techniques, it is possible to achieve amazingly natural-looking results. But how do we map out the best route to a better smile? And how do we know that the results will hold up over time?
Every individual has a unique set of conditions in his or her mouth and it is our job to figure out how you have come to your present state, dentally speaking. We need to correct or at least manage any factors that could risk the success of your treatment. These risk factors fall into four basic categories:
Periodontal Risk — This involves the condition of the structures that support your teeth, including your gum and bone tissue. It's important to establish good periodontal health before we perform any restorative or cosmetic procedures.
Biomechanical Risk — This has to do with the structural integrity of your teeth. We will look at whether any tooth structure has been lost due to decay, and take steps to reduce your susceptibility to decay if necessary.
Functional Risk — This relates to your bite: how your teeth, muscles and jaw joints are functioning. For example, do you have excessive tooth wear or joint pain? If so, you are at a higher risk in this category and we need to figure out why.
Aesthetic Risk — This is the most subjective of the categories as beauty is in the eye of the beholder. Still, if you display a lot of your teeth and gums when you smile, any issues you have (gum recession, for example) will be that much more visible and affect your smile more. We will have to take this into account when we plan your treatment.
Only when we have determined how best to minimize your risk in all four of these categories can we restore or enhance your smile in a way that will not only look great but also last as long as possible.
If your teeth are stained and discolored, misshapen or too small, porcelain veneers may be just the opportunity to treat yourself to a beautiful smile that can last for decades. They may be used to restore a single tooth that is broken or stained, or many teeth that are worn or discolored. If you have small teeth with gaps between them, veneers can close the spaces.
Porcelain laminate veneers are thin layers of dental restorative material that are bonded onto your teeth. With porcelain laminate veneers you can change a tooth's shape, size, and color. They require a minimal amount of tooth preparation (reduction of enamel on the original tooth) and are a great way to help you have a beautiful smile now and for decades to come.
They can last from seven to twenty years or more. Part of what determines their exact longevity is the health of your mouth. Gum tissues may deteriorate and the gum line may shrink back away from the roots of your teeth. So brushing, flossing, and other good dental habits are important in maintaining your investment in your smile.
Veneers don't require special treatment, and you can eat nearly anything with them. Keep in mind one precaution, however. Porcelain, like glass, can break with too much stress. This means that biting something that applies a strong twisting movement to your teeth may cause the veneers to shatter. If you grind your teeth at night you may need to wear a night guard to protect your veneers. It doesn't happen often, but if a veneer detaches it can usually be rebonded to the tooth.
