One of the best restorative options for slightly deformed, misaligned or stained teeth is a porcelain veneer. Composed of thin, laminated layers of dental material, the veneer is bonded to the outside of the tooth to transform both its shape and color to blend with other natural teeth.
Veneers are more than a technical process — they’re works of art produced by skilled artisans known as dental lab technicians. They use their skills to shape veneers into forms so life-like they can’t be distinguished from other teeth.
How technicians produce veneers depends on the material used. The mainstay for many years was feldspathic porcelain, a powdered material mixed with water to form a paste, which technicians use to build up layers on top of each other. After curing or “firing” in an oven, the finished veneer can mimic both the color variations and translucency of natural teeth.
Although still in use today, feldspathic porcelain does have limitations. It has a tendency to shrink during firing, and because it’s built up in layers it’s not as strong and shatter-resistant as a single composed piece. To address these weaknesses, a different type of veneer material reinforced with leucite came into use in the 1990s. Adding this mineral to the ceramic base, the core of the veneer could be formed into one piece by pressing the heated material into a mold. But while increasing its strength, early leucite veneers were thicker than traditional porcelain and only worked where extra space allowed for them.
This has led to the newest and most advanced form that uses a stronger type of glass ceramic called lithium disilicate. These easily fabricated veneers can be pressed down to a thickness of three tenths of a millimeter, much thinner than leucite veneers with twice the strength.Â And like leucite, lithium disilicate can be milled to increase the accuracy of the fit. It’s also possible to add a layer of feldspathic porcelain to enhance their appearance.
The science — and artistry — of porcelain veneers has come a long way over the last three decades. With more durable, pliable materials, you can have veneers that with proper care could continue to provide you an attractive smile for decades to come.

Even though baby teeth are not meant to last forever, they serve some very important functions for the time they are around. Healthy baby teeth allow your child to bite and chew food, articulate sounds correctly during speech, and, of course, to smile! They also help guide the permanent teeth, which will one day replace them, into proper alignment. So it’s important to take good care of them while they’re here. Let’s answer some frequently asked questions about pediatric dentistry.
Can I get my teeth cleaned while I’m pregnant?
Yes — and you should! Both the American Dental Association and the American Congress of Obstetricians and Gynecologists recommend that women keep up with their regular schedule of dental cleanings and exams during pregnancy. Not doing so can allow disease-causing oral bacterial to flourish, which can be a health risk for both the expectant mother and her fetus.
Do infants need their teeth brushed?
Yes, it’s important to start a daily oral hygiene routine as soon as the first baby tooth appears — usually sometime between six and nine months of age. Use a very soft-bristled child-sized toothbrush and just a smear of fluoride toothpaste (the size of a grain of rice). When your child turns 3, increase the amount of fluoride toothpaste to the size of a pea.
When should I take my child in for her first dental appointment?
The answer to this one may surprise you: All children should see a dentist by the age of 1. Early dental visits get children accustomed to having their mouths examined and their teeth cleaned. Establishing this healthy habit early will go a long way toward promoting a lifetime of good oral health.
Should I worry that my child sucks his thumb?
That depends on how old he is. Thumb sucking is a normal, comforting habit for babies and toddlers. Most outgrow it by the time they are 4. But kids who don’t are at increased risk for orthodontic issues later on. If your child seems unable to break the habit, let us know; we can give you more detailed recommendations at your next appointment.
What can I do to prevent my children from getting cavities?
Make sure your children have an effective daily oral hygiene routine that includes brushing with fluoride toothpaste twice a day and flossing at least once per day. If they are too young to do a good job by themselves, help them complete these important tasks. Keep their sugar consumption as low as possible; pay particular attention to beverages — soda, sports drinks and even 100 % natural fruit juices can all promote tooth decay. We can offer individualized advice on fighting cavities, and even provide fluoride treatments and dental sealants for extra protection against cavities. So don’t forget to bring your child in to the dental office for regular exams and cleanings!
Perhaps you haven’t thought of it quite this way, but saliva is one of the true wonders of the human body. This unassuming fluid performs a variety of tasks to aid digestion and help protect your mouth from disease. And you hardly notice it — except when it’s not there.
That’s the case for millions of people in America who have a chronic condition called xerostomia or “dry mouth.” This happens when the salivary glands don’t secrete enough saliva, normally two to four pints daily.
Of course, we can experience mouth dryness when we first wake up (saliva flow ebbs while we sleep), feel stressed, use tobacco, or consume alcohol and certain foods like onions or spices. It becomes a problem, though, when periods of low saliva become chronic. Without its preventive capabilities, you’ll be at much higher risk for dental diseases like tooth decay or periodontal (gum) disease.
Chronic dry mouth can occur for various reasons: systemic diseases like cancer or autoimmune deficiencies can cause it, as well as radiation or chemotherapy treatments. One of the most common causes, though, is medication, both over-the-counter and prescription. The surgeon general identifies over 500 known drugs that may inhibit saliva production, including some antihistamines, diuretics and antidepressants. It’s often why older people who take more medications than younger people suffer more as a population from dry mouth.
Because of its long-term health effects, it’s important to try to boost saliva flow. If your mouth is consistently dry, try to drink more fluids during the day. If you suspect your medication, see if your physician can prescribe a different drug. It also helps to drink a little water before and after taking oral medication.
We may also recommend medication or other substances that stimulate saliva or temporarily substitute for it. Xylitol, a natural alcohol sugar that also inhibits bacterial growth, can help relieve dryness. You’ll often find it in gums or mints.
Chronic dry mouth is more than a minor irritation — it can lead to more serious conditions. In addition to these tips, be sure to also keep up your regular dental visits and maintain a daily schedule of oral hygiene to prevent dental disease.
