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.

Porcelain veneers represent one of the best values in cosmetic dentistry, capable of radically changing a person’s smile with little tooth surface preparation. Still, the small amount of tooth enamel usually removed to accommodate them will permanently alter the affected teeth, to the point they will require a veneer or other restoration from then on.
The traditional veneer has remarkable versatility for solving a number of minor cosmetic problems, correcting mild tooth positioning problems and replacing lost or damaged enamel. But to avoid an unnatural bulky appearance, a portion of the tooth enamel must be permanently removed to accommodate them.
In recent years, though, a new concept known as “prepless veneers” has emerged in the field of cosmetic dentistry. Understandably, this new, “drill-free” veneer application has caused a lot of debate among dentists and patients alike, with concerns of bulky, overly-contoured teeth resulting from the technique. But the concept is growing as many well-regarded dentists have incorporated both minimal prep and prepless veneers into their service offerings.
The prepless veneer offers a cosmetic solution that doesn’t alter the tooth permanently. Using techniques such as feathering, which tapers and blends the veneer seamlessly with the tooth at the gum line, we can avoid an unnatural appearance while offering patients a much less invasive outcome.
The main disadvantage of prepless veneers at this time is that they’re not appropriate in every case. In fact, careful patient selection is a key to a successful outcome. For example, relatively large teeth or teeth positioned too far forward don’t work well with an added layer of thickness.
If, on the other hand, you have small, short or worn teeth, or teeth overshadowed by your lips — just to name a few likely scenarios — then you may benefit immensely from prepless veneers without permanent alteration to your teeth. A detailed examination is your first step to finding out if this new technique could provide you with a less-invasive smile makeover.

When die-hard music fans hear that their favorite performer is canceling a gig, it’s a big disappointment—especially if the excuse seems less than earth-shaking. Recently, British pop sensation Dua Lipa needed to drop two dates from her world tour with Bruno Mars. However, she had a very good reason.
“I’ve been performing with an awful pain due to my wisdom teeth,” the singer tweeted, “and as advised by my dentist and oral surgeon I have had to have them imminently removed.”
The dental problem Lipa had to deal with, impacted wisdom teeth, is not uncommon in young adults. Also called third molars, wisdom teeth are the last teeth to erupt (emerge from beneath the gums), generally making their appearance between the ages of 18-24. But their debut can cause trouble: Many times, these teeth develop in a way that makes it impossible for them to erupt without negatively affecting the healthy teeth nearby. In this situation, the teeth are called “impacted.”
A number of issues can cause impacted wisdom teeth, including a tooth in an abnormal position, a lack of sufficient space in the jaw, or an obstruction that prevents proper emergence. The most common treatment for impaction is to extract (remove) one or more of the wisdom teeth. This is a routine in-office procedure that may be performed by general dentists or dental specialists.
It’s thought that perhaps 7 out of 10 people ages 20-30 have at least one impacted wisdom tooth. Some cause pain and need to be removed right away; however, this is not always the case. If a wisdom tooth is found to be impacted and is likely to result in future problems, it may be best to have it extracted before symptoms appear. Unfortunately, even with x-rays and other diagnostic tests, it isn’t always possible to predict exactly when—or if—the tooth will actually begin causing trouble. In some situations, the best option may be to carefully monitor the tooth at regular intervals and wait for a clearer sign of whether extraction is necessary.
So if you’re around the age when wisdom teeth are beginning to appear, make sure not to skip your routine dental appointments. That way, you might avoid emergency surgery when you’ve got other plans—like maybe your own world tour!

Porcelain veneers are a great way to enhance an unattractive smile. But are they appropriate for teenagers? The answer usually depends on a patient’s current development stage and the type of veneer used.
Veneers are thin layers of porcelain bonded to the front of teeth. But even though quite thin, they can appear bulky if we don’t first remove some of the tooth’s enamel surface. This is irreversible, so the tooth may require a restoration from then on.
This could be a major issue for teens whose permanent teeth are still developing. During this period the tooth’s central pulp is relatively large and the dentin layer not fully developed. As a result, the pulp’s nerves are often closer to the surface than in an adult tooth. This increases risk of nerve damage during veneer preparation; if nerve damage occurs, the tooth could ultimately require a root canal treatment to save it.
On the other hand, some types of veneers don’t require tooth alteration (or only very little) beforehand. These “no-prep” or “minimal prep” veneers are best for certain situations like abnormally small teeth, so we must first determine if using such a veneer would be appropriate for your teen.
In effect, we’ll need to weigh these and other factors before determining if veneers are a safe choice for your teen. That being the case, it may be more advisable to consider more conservative cosmetic techniques first. For example, if enamel staining is the main issue, you could consider teeth whitening. Although the often amazing results eventually fade, whitening could still buy some time until the teeth have matured to safely apply veneers.
Slight deformities like chipping can often be corrected by bonding tooth-colored composite material to the tooth. In artistic hands it’s even possible to create a full veneer effect with very little if any tooth preparation. How much we can apply, though, depends on tooth size, and it won’t be as durable as a porcelain veneer.
With that said, veneers could be the right solution to enhance your teen’s smile. But, we’ll need to carefully consider their dental situation to ensure their new smile remains a healthy one.
A child's toothache is no fun for either the child or the parent. But if you're faced with this situation, don't panic — unless they have a fever or you notice facial swelling, it's unlikely an emergency.
Â Instead, take the following steps:
Find out where it hurts and for how long. Tooth pain can stem from a lot of causes, including decay or a localized area of infection called an abscess. See if your child can tell you if it's coming from one particular tooth or from a general area. Although children can't always judge how long they've hurt, try to get a general idea so you'll know if you need to call us sooner rather than later.
Look for problem signs in the mouth. As you look where they say it hurts, see if you can see brown spots or cavities on any teeth — this would indicate tooth decay. Look also at the gums or inner areas of the mouth for sores or swelling. Unless they've had an injury, this could indicate an abscess.
Try to dislodge any food shards between teeth. It's also possible the pain is coming from a piece of hard food like a popcorn kernel wedged between their teeth. Help them gently floss between the teeth to see if you can dislodge any.
Try to ease the pain. Although you may not need to see us immediately, your child's mouth still aches. You can help relieve it temporarily with a child's dose of ibuprofen or acetaminophen. You can also apply an ice pack to the outside cheek for swelling, but don't apply the ice directly to the skin, which can burn it. And don't rub aspirin or other pain relievers on the gums — they're acidic and can irritate soft tissue.
See us for a full examination. It's wise to have any tooth pain checked — the question is often how soon. You should see us the same day or first thing in the morning if the pain has persisted for more than a day or night, pain relievers haven't eased the pain or they have fever or facial swelling. If the pain is short-lived you can usually wait until the next day — but do get it checked out.
