For generations, dentures have helped people avoid the dire consequences of total teeth loss. Now, implant technology is making them even better.
Composed of life-like prosthetic teeth fixed within a plastic or resin gum-colored base, dentures are manufactured to fit an individual patient’s mouth for maximum fit, comfort and performance. But dentures also have a critical drawback—they can’t stop bone loss in the jaw.
Bone is constantly regenerating as older cells dissolve and then are replaced by newer cells. In the jawbone, the forces generated when we chew travel through the teeth to the bone and help stimulate this new cell growth. When teeth are missing, though, the bone doesn’t receive this stimulus and may not regenerate at a healthy rate, resulting in gradual bone loss.
Dentures can’t transmit this chewing stimulus to the bone. In fact, the pressure they produce as they rest on top of the gums may actually accelerate bone loss. Over time then, a denture’s once secure and comfortable fit becomes loose.
In the past, most patients with loose dentures have had them relined with new dental material to improve fit, or have new dentures created to conform to the changed contours of the jaws. But implant technology now offers another alternative.
Implants are in essence a tooth root replacement. Dentists surgically implant a titanium metal post directly into the jawbone that naturally attracts bone cells to grow and adhere to it over time (a process called osseointegration). This not only creates a secure and lasting hold, it can also stop or even reverse bone loss.
Most people know implants as single tooth replacements with a porcelain crown attached to the titanium post. But a few strategically placed implants can also support either removable or fixed dentures. Removable dentures (also called overdentures) usually need only 3 or 4 implants on the top jaw and 2 on the bottom jaw for support through built-in connectors in the dentures that attach to the implants. A fixed bridge may require 4-6 implants to which they are permanently attached.
There are pros and cons for each of these options and they’re both more expensive than traditional dentures. In the long run, though, implant-supported dentures could be more beneficial for your bone health and hold their fit longer.
With exciting innovations in cosmetic dentistry over the last few decades, we can now transform nearly any unattractive smile. One of the best and most cost-effective of these is the porcelain veneer. These thin layers of dental porcelain are bonded over the front of chipped, slightly misaligned or stained teeth to create an entirely new look.
Veneers have evolved over time, especially with the materials they contain that give them their beauty and life-likeness. The first veneers were made mainly of feldspathic porcelain, a mineral composition known for its similarity in color and translucence to natural teeth.
But because this early porcelain had a high amount of silica (in essence, glass), and because they were created through overlaying several thin layers that weren’t as strong as a single piece, they were prone to shattering. This made them problematic for teeth subject to heavy biting forces or patients with clenching or grinding habits.
The situation changed dramatically in the 1990s, when dental labs began adding Leucite, a sturdier glass-like mineral that didn’t diminish the porcelain’s translucence. Not only did Leucite make veneers more shatter-resistant, it also enabled dental technicians to fashion most of the veneer in one piece to further strengthen it.
More recent veneers may now incorporate an even stronger material called lithium disilicate. Because lithium disilicate has twice the strength of Leucite, veneers made with it can be as thin as 0.3 millimeters. Not only does this blend together the most desirable qualities expected of a veneer—strength, aesthetic appeal and easy fabrication—it allows for a broader range of situations and uses.
Both of these materials can be pressed or milled to assume the exact shape necessary to fit a particular tooth. The manufacturing process also allows for creating smaller veneers that can then be overlaid with porcelain for the most life-like appearance possible.
Thanks to these stronger materials enhancing the natural beauty of porcelain, we now have a wider creative palate for transforming your smile.

Want to know the exact wrong way to pry open a stubborn lid? Just ask Jimmy Fallon, host of NBC-TV’s popular “Tonight Show.” When the 40-year-old funnyman had trouble opening a tube of scar tissue repair gel with his hands, he decided to try using his teeth.
What happened next wasn’t funny: Attempting to remove the cap, Fallon chipped his front tooth, adding another medical problem to the serious finger injury he suffered a few weeks before (the same wound he was trying to take care of with the gel). If there’s a moral to this story, it might be this: Use the right tool for the job… and that tool isn’t your teeth!
Yet Fallon is hardly alone in his dilemma. According to the American Association of Endodontists, chipped teeth account for the majority of dental injuries. Fortunately, modern dentistry offers a number of great ways to restore damaged teeth.
If the chip is relatively small, it’s often possible to fix it with cosmetic bonding. In this procedure, tough, natural-looking resin is used to fill in the part of the tooth that has been lost. Built up layer by layer, the composite resin is cured with a special light until it’s hard, shiny… and difficult to tell from your natural teeth. Best of all, cosmetic bonding can often be done in one office visit, with little or no discomfort. It can last for up to ten years, so it’s great for kids who may be getting more permanent repairs later.
For larger chips or cracks, veneers or crowns may be suggested. Veneers are wafer-thin porcelain coverings that go over the entire front surface of one or more teeth. They can be used to repair minor to moderate defects, such as chips, discolorations, or spacing irregularities. They can also give you the “Hollywood white” smile you’ve seen on many celebrities.
Veneers are generally custom-made in a lab, and require more than one office visit. Because a small amount of tooth structure must be removed in order to put them in place, veneers are considered an irreversible treatment. But durable and long-lasting veneers are the restorations of choice for many people.
Crowns (also called caps) are used when even more of the tooth structure is missing. They can replace the entire visible part of the tooth, as long as the tooth’s roots remain viable. Crowns, like veneers, are custom-fabricated to match your teeth in size, shape and color; they are generally made in a dental lab and require more than one office visit. However, teeth restored with crowns function well, look natural, and can last for many years.
So what happened to Jimmy Fallon? We aren’t sure which restoration he received… but we do know that he was back on TV the same night, flashing a big smile.

It’s likely you depend on your regular dentist for the lion’s share of your dental care. But in cases of advanced disease or trauma, you may need the services of a dental specialist.
This could be the case with periodontal (gum) disease, a bacterial infection triggered by a thin biofilm on tooth surfaces called dental plaque that isn’t adequately removed through daily oral hygiene practices. While your regular dentist can effectively treat many forms of gum disease, there are times when you should see a periodontist who specializes in the gum, supporting bone and connective tissues.
So, when should you see a periodontist for gum disease treatment? Here are 3 situations that may call for this important dental specialist.
If your dentist refers you. Your dentist may be quite proficient in treating gum disease, mainly by removing the dental plaque and tartar sustaining the infection. But if the infection has advanced deep within the gum tissues especially around the roots and bone, you may need more advanced measures, including surgery, performed by a periodontist.
If you’d like a second opinion. Of course, you don’t need a referral to see a periodontist. You can make an appointment with one for another opinion about your diagnosis and recommended treatment plan. If you choose to see a periodontist, make sure they have access to all your dental and medical records, as well as your past health history.
If you have other health issues. Gum disease often doesn’t occur in a vacuum – it may exist and even influence (or be influenced by) other inflammatory medical conditions. If you have such a condition like diabetes or cardiovascular disease, you may opt to see a periodontist first for a more comprehensive evaluation.
In the meantime, keep an eye out for the first signs of disease including red, swollen or bleeding gums (if you smoke, be aware smoking hides these signs of disease). And practice daily brushing and flossing as well as obtaining regular dental cleanings to keep plaque accumulation to minimum. Preventing gum disease and getting treatment as early as possible may help you avoid more invasive treatments later.

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.
