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.
When your favorite baseball team wins, it's hard not to get excited — especially if you're right there in the stadium. It's even better when a player tosses the ball to fans. But sometimes, in the heat of the moment, things can go awry.
That's what happened during a recent game at New York's Yankee Stadium. After catching the ball that ended the game in an 8-2 Dodgers win, Los Angeles outfielder Yasiel Puig tossed it into a cheering crowd of supporters. “I saw it coming at me and I remember thinking, 'I don't have a glove to catch this ball,'” Dodgers fan Alyssa Gerharter told the New York Daily News. “I felt it hit me and I could feel immediately with my tongue there's a hole. And I looked down at my hand and saw there's a tooth in my hand.”
Ouch. Just like that, one fan's dream became… a not-so-good dream. But fortunately for the 25-year-old software engineer, things went uphill from there. Ushers quickly escorted her into a first-aid room at the stadium. She was then rushed to a nearby hospital, where the upper front tooth was re-inserted into her jaw. After a follow-up appointment at her dentist's office the next day, Gerharter said she remains hopeful the re-inserted tooth will fuse with the bone, and won't require replacement.
We hope so too. And in fact, she has as good a chance of a successful outcome as anyone, because she did everything right. If you're not sure what to do about a knocked-out tooth, here are the basics:
- locate the tooth, handle it carefully (don't touch the root surface), and if possible gently clean it with water
- try to open the person's mouth and find the place where the tooth came from
- carefully re-insert the tooth in its socket if possible, making sure it is facing the right way
- hold the tooth in place with a soft cloth as you rush to the dental office or the nearest urgent care facility
- if it can't be replaced in its socket, place the tooth in a special preservative solution or milk, or have the person hold it between the cheek and gum (making sure they won't swallow it) — and then seek immediate care at the dental office
- follow up at the dental office as recommended
In general, the quicker you perform these steps, the more likely it is that the tooth can be preserved. How quick is quick? The best outcomes are expected when re-implantation occurs in no more than five minutes. So if you're in this situation, don't wait: get (or give) appropriate first aid right away — it just might save a tooth!

When you’re among the top players in your field, you need every advantage to help you stay competitive: Not just the best equipment, but anything else that relieves pain and stress, and allows you to play better. For top-seeded Canadian tennis player Milos Raonic, that extra help came in a somewhat unexpected form: a custom made mouthguard that he wears on the court and off. “[It helps] to not grind my teeth while I play,” said the 25-year-old up-and-coming ace. “It just causes stress and headaches sometimes.”
Mouthguards are often worn by athletes engaged in sports that carry the risk of dental injury — such as basketball, football, hockey, and some two dozen others; wearing one is a great way to keep your teeth from being seriously injured. But Raonic’s mouthguard isn’t primarily for safety; it’s actually designed to help him solve the problem of teeth grinding, or bruxism. This habitual behavior causes him to unconsciously tense up his jaw, potentially leading to problems with muscles and teeth.
Bruxism is a common issue that’s often caused or aggravated by stress. You don’t have to be a world-class athlete to suffer from this condition: Everyday anxieties can have the same effect. The behavior is often worsened when you consume stimulating substances, such as alcohol, tobacco, caffeine, and other drugs.
While bruxism affects thousands of people, some don’t even suspect they have it. That’s because it may occur at any time — even while you’re asleep! The powerful jaw muscles that clench and grind teeth together can wear down tooth enamel, and damage both natural teeth and dental work. They can even cause loose teeth! What’s more, a clenching and grinding habit can result in pain, headaches and muscle soreness… which can really put you off your game.
There are several ways to relieve the problem of bruxism. Stress reduction is one approach that works in some cases. When it’s not enough, a custom made occlusal guard (also called a night guard or mouthguard) provided by our office can make a big difference. “When I don’t sleep with it for a night,” Raonic said “I can feel my jaw muscles just tense up the next day. I don’t sense myself grinding but I can sort of feel that difference the next day.”
Â An occlusal guard is made from an exact model of your own mouth. It helps to keep your teeth in better alignment and prevent them from coming into contact, so they can’t damage each other. It also protects your jaw joints from being stressed by excessive force. Plus, it’s secure and comfortable to wear. “I wear it all the time other than when I’m eating, so I got used to it pretty quickly,” said Raonic.
Teeth grinding can be a big problem — whether you put on your game face on the court… or at home. If you would like more information about bruxism, contact us or schedule an appointment for a consultation.

As a cancer patient, you know how important radiation and chemotherapy are to overcoming the disease. But these treatments often come at a price to other aspects of your health, including your teeth and gums if the treatment target includes the head or neck regions.
Radiation and chemotherapy are effective because they target and destroy cancer cells. Unfortunately, they may also kill non-cancerous, healthy cells; in the mouth, for example, they can damage the cells in the salivary glands and disrupt their ability to produce adequate saliva flow, leading to xerostomia (dry mouth).
This could seriously affect your teeth’s protective enamel shell. As we eat or drink, our mouth’s pH level can become too acidic. Acid is your enamel’s primary enemy because it causes the minerals in the enamel to soften and dissolve (de-mineralization). Saliva neutralizes acid and replaces much of the enamel’s minerals.
Without adequate saliva flow, the enamel will tend to erode over time. You can further aggravate the situation if you routinely consume acidic foods and drinks, like sipping energy drinks or soda during the day. Once the enamel is gone it can’t be replaced naturally, and the teeth will be in serious danger of tooth decay and eventual loss of function and appearance.
To avoid these consequences you should take steps during cancer treatment to reduce your risk for xerostomia or other unhealthy mouth conditions: limit your consumption of acidic foods and beverages; use mouth rinses to counteract acidity and inhibit bacterial growth; and promote saliva flow through medication.
It may be, though, that enamel erosion and subsequent tooth damage is unavoidable. In this case, you may need to consider restorative options with artificial crowns or other cosmetic enhancements — not only to improve your appearance but also to protect your natural teeth from further damage.
Before considering the latter, you should undergo a complete dental examination to assess your condition and make sure you have adequate bone and gum support, and any dental disease under control. From here, we can go about restoring the attractive smile that may have faded during your battle with cancer.
Our main focus as your dentist is to keep your teeth and gums healthy and functional. But there’s another important aspect of care — your teeth’s appearance. It’s not just a superficial concern: your smile can have a profound effect on your self-image, as well as your personal and professional relationships.
This is the realm of cosmetic dentistry: served by both specialists and general dentists, it focuses on altering your teeth’s appearance with treatments as basic as teeth whitening or as comprehensive as dental implants. The goal, however, is the same: a new, more attractive smile.
In a way, cosmetic dentistry begins with you and oral hygiene. The twin tasks of brushing and flossing to remove dental plaque not only lowers your risk for tooth decay or periodontal (gum) disease, they also improve the appearance of the tooth surface. There are, however, circumstances where otherwise healthy or repaired teeth may need extra cosmetic attention due to chipping, misshape or staining. In these cases, a truly cosmetic approach may be necessary.
One approach is to cover a tooth’s blemishes. Veneers, for example, are thin, layered pieces of dental porcelain shaped and colored like natural teeth that are bonded to the outside of an unattractive tooth. In other cases, a tooth may require a life-like porcelain crown that completely covers it to gain the same effect.
Missing teeth, of course, pose a different challenge, but here there are a wide range of solutions: dental implants, fixed bridgework or removable full or partial dentures. Advancements in dental materials and techniques can produce new teeth that are so life-like and natural that they’re imperceptible from the real thing.
Â These and other measures like orthodontics can all be used to turn a smile you find embarrassing into one you’re confident to share with the world. It begins, though, with both you and us taking a good, close look at your current smile — a smile analysis, if you will.
After assessing both your current needs and your expectations for change, we can develop an appropriate treatment plan. It might be quite simple or with multiple treatment stages, but it will be the best plan for you. Through cosmetic dentistry we have the means to help you achieve a new, more confident smile.
