If you're in need of a crown to cover a damaged tooth, you have a lot of options. But before you choose, you need to know what you want. Would you be happy with an affordable, well-fitting crown that holds up well and allows you to chew comfortably? Or are you interested in a more expensive one that also provides the most attractive result?
Crowns have been a mainstay in dentistry for generations. The first were made of metals like gold or silver — durable and effective but not very attractive.
In time, a ceramic material known as dental porcelain began to make its appearance in crowns. Dental porcelain could be fashioned to resemble the color and texture of natural teeth, but it had a significant drawback: it could be brittle and subject to shattering under chewing pressure.
This problem was somewhat addressed with the innovation of a crown with a metal substructure fused with an outer layer of porcelain. These porcelain-fused-to-metal (PFM) crowns combined the best advantages of both materials: strength and life-likeness. Up until around the mid-2000s, PFM made up over 80% of crowns.
But later porcelains continued to improve in strength, beginning in 1993 with the introduction of a Lucite-reinforced material. Newer formulations like lithium disilicate or zirconium oxide (now considered the strongest porcelain) have made all-porcelain crowns a viable option. Today, an estimated 60% of new crowns are all-porcelain.
From an appearance standpoint, all-porcelain crowns achieve the best results. The most realistic crown can be costly — not because of the material but the level of artistry required. A skilled dental technician will spend several hours, including brushing on as many as fifteen coats of liquid porcelain to the crown, to achieve the most life-like outcome. Your insurance plan, if you have one, will most likely not pay as high a percentage for that type of crown.
In the end, it's your decision as to what type of crown you wish to have. We'll help you weigh your options and decide what's best for you and your budget.
Orthodontics shares a principle with the classic tug of war game: if you want things to move in the right direction you need a good anchor. Anchors help braces and other appliances apply constant pressure to misaligned teeth in the direction they need to go to correct a malocclusion (poor bite).
Orthodontic treatments work in cooperation with an existing oral mechanism that already moves teeth naturally in response to biting forces or other environmental factors. The key to this mechanism is an elastic tissue known as the periodontal ligament that lies between the tooth and the bone. Besides holding teeth in place through tiny attached fibers, the ligament also allows the teeth to move in tiny increments.
Braces’ wires laced through brackets affixed to the teeth exert pressure on them in the desired direction of movement –the periodontal ligament and other structures do the rest. To maintain that pressure we need to attach them to an “anchor”—in basic malocclusions that’s usually the back molar teeth.
But not all malocclusions are that simple. Some may require moving only certain teeth while not moving their neighbors. Younger patients’ jaws and facial structures still under development may also need to be considered during orthodontic treatment. That’s why orthodontists have other anchorage methods to address these possible complications.
One example of an alternate anchorage is a headgear appliance that actually uses the patient’s skull as the anchor. The headgear consists of a strap running around the back of the head and attached in front to orthodontic brackets (usually on molar teeth). The pressure it exerts can trigger tooth movement, but it can also help influence jaw development if an upper or lower jaw is growing too far forward or back.
Another useful anchorage method is a tiny metal screw called a temporary anchorage device (TAD) that is implanted into the jawbone above the teeth through the gums. Orthodontists then attach elastic bands between implanted TADs and specific braces’ brackets or wires to exert pressure on certain teeth but not others with pinpoint accuracy. After treatment the TADs can be easily removed.
Using these and other appliances allows orthodontists to customize treatment to an individual patient’s particular malocclusion. With the right anchor, even the most complex bite problem can be transformed into a beautiful and healthy smile.

Like the rest of their bodies, children’s teeth and mouth are on a rapid development track. By the time they’re young adults, they will have had two sets of teeth, extensive bone growth and a noticeable change in their features. The natural process is truly amazing.
But dental disease can easily derail their development, with tooth decay the most common problem children encounter. More than at any other time of life, preventive dental care is a top priority.
True preventive care for your child includes the entire mouth, not just the teeth. Our main focus, of course, is to head off tooth decay before it develops, including the application of topical fluoride or sealants when appropriate. But we also monitor bite development and provide protection against sports injuries or other forms of trauma with customized mouth guards.
You also have a part to play in your child’s preventive dental care. It begins when your child’s first teeth begin to emerge in the mouth — the point when you should begin brushing them. You can also reduce the risk of dental disease by providing a nutritious diet that’s high in fresh fruits and vegetables and low in sugar, especially between-meal snacks.
You should also start regular dental visits around their first birthday. This is not only the best time to begin professional care, but your child will also have an easier time at this age becoming comfortable with visiting the dentist than waiting until they’re older.
Taking care of your child’s teeth is a working partnership between you and us: we provide the professional care your child needs to develop properly, while you look to their daily hygiene and nutrition, which is just as important for your child’s healthy development. Through our partnership, we can ensure your child is getting the very best start toward a lifetime of healthy teeth and gums.
Want to give your kids the best start possible for a lifetime of good dental health? The most important thing you can do is train them in effective brushing and flossing. It's more than having a nice smile and fresh breath: these hygiene tasks remove the daily buildup of bacterial plaque, the primary cause for both tooth decay and periodontal (gum) disease, which are most responsible for poor oral health.
But those aren't the only habits they should be cultivating. Here are 3 tips for helping your child develop great dental health habits.
Encourage healthy eating. Teeth and gums are like other parts of the body: they need the "building blocks" found in nutritious foods to help grow strong, healthy tissues. By focusing on a diet leaner on processed items and richer in whole, less-processed vegetables, meats and dairy products, you'll be helping your child build strong defenses against dental disease.
Keep sugary snacks under control. Of all the items in your child's diet, sugar could have the greatest impact on their teeth. Disease-causing bacteria thrive on this particular carbohydrate, multiplying and producing mouth acid—the main enemy of tooth enamel—as a byproduct. So, limit sugary snacks as much as possible, opting instead for more nutritional between-meal treats. In fact, try to make sure they only consume sugary treats at mealtime, not in between.
Encourage an end to thumb-sucking or pacifiers by age 3. Most infants and very young children suck their thumbs or, alternatively, a pacifier. There's no harm in this habit unless it extends into later childhood where it could affect their bite. You can avoid this outcome by encouraging your child with mainly positive reinforcement to stop sucking their thumbs or other objects before their third birthday. Your dentist can also help with tips and support in those efforts.

If your teenager is in need of orthodontic treatment, you might automatically think braces. But while this decades-old appliance is quite effective, it isn’t the only “tooth movement” game in town any more. Clear aligners are another choice your teenager might find more appealing.
Clear aligners are a sequential set of computer-generated plastic trays that are worn by a patient one after the other, usually for about two weeks per tray. The trays are fabricated using 3-D computer modeling of the patient’s mouth, each one slightly different from the last to gradually move teeth to the desired new positions.
So, why choose clear aligners over braces?
They’re nearly invisible. Because they’re made of a clear polymer material, they’re not nearly as noticeable as metal braces. In fact, they may go completely unnoticed to the casual observer.
They’re removable. Unlike metal braces, which are fixed in place by an orthodontist, clear aligners can be removed by the wearer. This makes brushing and flossing much easier, and they can also be removed for eating or special occasions. That said, though, they should be worn at least 20 to 22 hours each day to be effective.
They’re becoming more versatile. With some complicated malocclusions (poor bites), braces and other orthodontic appliances may still be necessary. But innovations like added power ridges in clear aligners can more precisely control which teeth move and which don’t. This has greatly increased the number of poor bite scenarios where we can appropriately use clear aligners.
If you’d like to consider clear aligners, just remember they require a bit more self-discipline on the part of the wearer than braces. And once the treatment finishes, they’ll still need to wear a retainer just as with metal braces to help keep the repositioned teeth from reverting to their old positions.
If you think your teen is up to the challenge and their particular situation can be corrected with this innovative technology, then clear aligners could be a great choice.
