Dentists are frequently asked about the materials that are used for veneers, dental restorations that can rejuvenate a smile.
There are some wonderful choices, each with its own characteristics, with porcelain dominating the field. Though composite plastic material can be used, it is not a common choice when the entire facial – or outside – surface on the tooth needs restoration because it can chip and/or discolor when used as a thin covering. A composite is best used as a filling material or to restore a fractured tooth corner. This is why porcelain is the material of choice, as it is strong and color-stable.
A Smile with Style
There are a number of choices to be made among the various types of porcelain. Much like there are different types of countertops with unique characteristics – like Corian or quartz or marble – each has its advantages and disadvantages, though in veneer work, the differences are subtle.
Feldspathic porcelain is among the prettiest, though it is labor-intensive to fabricate and is a little less strong than the others. Other porcelains, like Empress or E-max, combine beauty and a little more strength. More recently, the use of Zirconium-type porcelain has increased; though it initially was known for its strength, recent incarnations of the material allow it to be aesthetic, as well. The Lumineer, developed by a California laboratory, is also used on occasion; it is actually a brand-name for their veneer, much like Kleenex is a brand name for facial tissue.
In any case, the choice of porcelains for veneers should be based on several factors, including aesthetics, strength and required thickness. Other influences include the colors of the teeth they are covering, the type of bite/occlusion the patient has, and the relative strength of the tooth underneath.

In the New Year, many of us make resolutions. For some of us, it may have an emotional component, like “spending more time with our family.” For others, it may be of a physical nature, like trying to lose weight. But there may be other physical needs, like fixing your teeth.
When you get your teeth taken care of, it can improve your overall health, chewing function, oral musculature, nutrition, and appearance. The goals of losing weight are similar. Walking and exercise are easier, medical issues like high blood pressure and diabetes are better controlled and you look better as well. But while weight loss can be achieved by limiting your food/caloric intake, dental improvements often require the help of a dental professional – like a dental hygienist or general dentist.
What Happens at the Checkup
When you are in the chair getting your teeth cleaned, the hygienist removes hard deposits (tartar) as well as soft ones (plaque). Though the hard deposits are mostly annoying, the plaque involves bacteria which can be detrimental to your teeth and overall health.
It’s the bacteria that feed off many of our foods causing acid to attack our teeth and gums, causing cavities and tissue problems. You can resolve to do a better job at home brushing and flossing to remove debris, but a trip to the hygienist two or three times a year can ensure that you are doing it effectively, as well as eliminating the “hard to find” tartar and plaque.
Digital radiographs ( x-rays) and photos can be used to look for decay, bone abnormalities and periodontal diseases. The hygienist will also look for possible tissue problems or growths that may – or may not – be cancer-related.
And at your visit, the dentist plays a similar role, in both diagnosing and treating problems.
