For centuries, people who've lost all their teeth have worn dentures. Although materials in today's dentures are more durable and attractive than those in past generations, the basic design remains the same — prosthetic (false) teeth set in a plastic or resin base made to resemble gum tissue.
If you're thinking of obtaining dentures, don't let their simplicity deceive you:Â a successful outcome depends on a high degree of planning and attention to detail customized to your mouth.
Our first step is to determine the best positioning for the prosthetic teeth. It's not an “eyeball” guess — we make a number of calculations based on the shape and size of your jaws and facial features to determine the best settings within the resin base. These calculations help us answer a few important questions for determining design: how large should the teeth be? How far forward or back from the lip? How much space between the upper and lower teeth when the jaws are at rest?
We also can't forget about the artificial gums created by the base. How much your gums show when you smile depends a lot on how much your upper lip rises. We must adjust the base size to accommodate your upper lip rise so that the most attractive amount of gum shows when you smile. We also want to match as close as possible the color and texture of your natural gum tissues.
There's one other important aspect to manage: how your upper and lower dentures function together when you eat or speak. This means we must also factor your bite into the overall denture design. This may even continue after your dentures arrive: we may still need to adjust them while in your mouth to improve function and comfort.
Ill-fitting, dysfunctional and unattractive dentures can be distressing and embarrassing. But with careful planning and customization, we can help ensure your new dentures are attractive and comfortable to wear now and for years to come.

You feel great about your new smile, thanks to dental implants! And you may also be feeling relief as the problems with your former teeth fade into the past.
But that doesn’t mean you can drop your guard on periodontal (gum) disease. Even though implants are impervious to decay, the natural tissues supporting them are vulnerable to periodontal (gum) disease. If they become diseased, your implants could lose their bone support and eventually fail.
And that failure could happen quickly. That’s because, as life-like as they are, implants don’t have one important advantage of real teeth: an attachment to a connective tissue called the periodontal ligament. This tough but elastic ligament lies between the teeth and the bone, attaching to both with tiny extending fibers and holding the teeth in place.
And that’s not all: Because the periodontal ligament contains an abundance of blood vessels, it can supply antibodies to help fight infection. The body’s defenses may not be able to stop disease, but they can certainly inhibit its progress.
Implants can’t benefit from this infection-fighting mechanism. So, when an infection arises in the gums surrounding an implant, it can spread rapidly through a form of gum disease known as peri-implantitis (literally “inflammation around an implant”). If we don’t stop it with prompt treatment, you could lose bone support from your implant and eventually lose it, sometimes in quick fashion.
That’s why you should clean your implants everyday like you do the rest of your teeth with brushing and flossing. You should also visit us regularly for dental cleanings. A dental cleaning involving implants is similar to one with natural teeth, except the hygienist won’t use metal instruments on the implants—this could create tiny scratches on their surface. Instead, they’ll use nylon or plastic instruments or ultrasonic equipment to clean them.
You should also make a dental appointment as soon as you notice swollen, reddened or bleeding gums. If you have gum disease, we can stop the infection through treatment and restore your gums to health. This can be a long and involved process, but it’s necessary to preserve your implants.
It’s true that implants can change your life. If you want to enjoy that change for a long time, take care of your implants and the natural tissues that support them.

Say “bacteria,” especially in the same sentence with “disease” or “infection,” and you may trigger an immediate stampede for the hand sanitizer. The last thing most people want is to come in contact with these “menacing” microorganisms.
If that describes you, however, you’re too late. If you’re of adult age, there are already 100 trillion of these single-celled organisms in and on your body, outnumbering your own cells 10 to 1. But don’t panic: Of these 10,000-plus species only a handful can cause you harm—most are either harmless or beneficial, including in your mouth.
Thanks to recent research, we know quite a bit about the different kinds of bacteria in the mouth and what they’re doing. We’ve also learned that the mouth’s microbiome (the interactive environment of microscopic organisms in a particular location) develops over time, especially during our formative years. New mothers, for example, pass on hundreds of beneficial species of bacteria to their babies via their breast milk.
As our exposure to different bacteria grows, our immune system is also developing—not only fighting bacteria that pose a threat, but also learning to recognize benevolent species. All these factors over time result in a sophisticated, interrelated bacterial environment unique to every individual.
Of course, it isn’t all sweetness and light in this microscopic world. The few harmful oral bacteria, especially those that trigger tooth decay or periodontal (gum) disease, can cause enormous, irreparable damage to the teeth and gums. It’s our goal as dentists to treat these diseases and, when necessary, fight against harmful microorganisms with antibacterial agents and antibiotics.
But our growing knowledge of this “secret world” of bacteria is now influencing how we approach dental treatment. A generalized application of antibiotics, for example, could harm beneficial bacteria as well as harmful ones. In trying to do good we may run the risk of disrupting the mouth’s microbiome balance—with adverse results on a patient’s long-term oral health.
The treatment strategies of the future will take this into account. While stopping dental disease will remain the top priority, the treatments of the future will seek to do it without harming the delicate balance of the mouth’s microbiome.
