Even in the 21st Century, losing most or all of your teeth is still an unfortunate possibility. Many in this circumstance turn to dentures, as their great-grandparents did, to restore their teeth. But today's dentures are much different from those of past generations—and dental implants are a big reason why.
The basic denture is made of a gum-colored, acrylic base with artificial teeth attached. The base is precisely made to fit snugly and comfortably on the patient's individual gum and jaw structure, as the bony ridges of the gums provide the overall support for the denture.
Implants improve on this through two possible approaches. A removable denture can be fitted with a metal frame that firmly connects with implants embedded in the jaw. Alternatively, a denture can be permanently attached to implants with screws. Each way has its pros and cons, but both have two decided advantages over traditional dentures.
First, because implants rather than the gums provide their main support, implant-denture hybrids are often more secure and comfortable than traditional dentures. As a result, patients may enjoy greater confidence while eating or speaking wearing an implant-based denture.
They may also improve bone health rather than diminish it like standard dentures. This is because the forces generated when chewing and eating travel from the teeth to the jawbone and stimulate new bone cell growth to replace older cells. We lose this stimulation when we lose teeth, leading to slower bone cell replacement and eventually less overall bone volume.
Traditional dentures not only don't restore this stimulation, they can also accelerate bone loss as they rub against the bony ridges of the gums. Implants, on the other hand, can help slow or stop bone loss. The titanium in the imbedded post attracts bone cells, which then grow and adhere to the implant surface. Over time, this can increase the amount of bone attachment and help stymie any further loss.
An implant-supported denture is more expensive than a standard denture, but far less than replacing each individual tooth with an implant. If you want the affordability of dentures with the added benefits of implants, this option may be worth your consideration.

The humble squirrel—darlings to some, bird feeder-robbing nuisances to others—has its own month. Since 1995, the Squirrel Lovers Club of Chicago has celebrated October as Squirrel Awareness Month to pay tribute to this diverse family of rodents with over 270 species. It's also an opportunity to indulge in our favorite “squirrelly” fact: Squirrels' teeth don't stop growing.
And we do mean grow. A squirrel's four front incisors increase about 6 inches a year—a good thing since squirrels put those teeth through their paces gnawing through hard-shelled nuts and seeds. If they didn't keep growing, you'd see plenty of squirrels with worn-to-nothing front teeth.
We humans have some cause to be envious because, unlike squirrels, our permanent teeth stop growing by the time we reach adulthood. That could be a problem since nearly all of us encounter tooth wear as we age.
And it could be even worse. Bad habits like crunching ice, biting into hard foods or using our teeth as tools can contribute to accelerated wear. Some people also involuntarily clench or grind their teeth, creating higher than normal pressure that can wear down teeth.
Suffice it to say, it's worth the effort to quit conscious bad dental practices to prevent your teeth from wearing faster than normal. A teeth-grinding habit, though, may require more than willpower: We'll need to look at other ways to reduce its effect on your teeth.
First, you may want to try to reduce chronic stress, the top contributor to adult teeth grinding. Better stress management with the help of counseling, relaxation techniques, biofeedback or group therapy can all help reduce the occurrence of this destructive habit.
Such efforts, though, can take time. In the meantime, we may be able to help you reduce the effect of a grinding habit with a custom-made mouth guard. This plastic guard worn in the mouth prevents teeth from making hard contact with each other during grinding, and so it reduces the damaging forces that can wear down teeth.
By the way, if you've already experienced excessive tooth wear, not all hope is lost. We may be able to restore your teeth to normal length with the help of bonded porcelain veneers or crowns. After a thorough evaluation, we can give you options for turning back the “age clock” on your smile.
Our teeth may not continuously grow like squirrels', but we can still protect them from the effects of excessive wear. Good dental practices and habits—and restorative measures when necessary—can keep your smile looking as young as ever.
Brushing and flossing daily, and dental visits at least twice a year: These are the essential things you should be doing to protect your teeth and gums against dental disease. But you're also getting an automatic assist from your body through saliva, that humble fluid swishing around in your mouth, to protect your oral health.
It's more than simply “mouth water”: Without saliva and its various components, your risk for tooth decay or periodontal (gum) disease would be much higher. Here are 4 ways saliva helps you keep your teeth and gums healthy.
Cleansing. Chewing prepares your food for digestion, but in the process produces tiny particles of food debris. Settling on tooth surfaces, these bits become part of the dental plaque that forms on your teeth and develops the ideal breeding ground for disease-causing bacteria. Saliva helps rinse away much of this debris—particularly sugar, the primary food source for bacteria.
Protection. Saliva is the first line defense against disease-causing microorganisms entering the mouth. The primary source of this protection is a protein-based antibody called Immunoglobulin A (IgA), which directly fights infection-causing organisms. Another protein in saliva, lactoferrin (also found in tears), interferes with bacterial growth.
Buffering. The main enemy of tooth enamel is mouth acid, produced by oral bacteria and the foods that we eat. Saliva neutralizes acid to help the mouth maintain its normally neutral pH range. And it works fast: Saliva can buffer acid and restore balance within thirty minutes to an hour after eating.
Re-mineralization. It's normal for acid to build up after eating, and for it to quickly remove minerals from surface enamel, a process called de-mineralization that can soften and weaken the enamel. But saliva helps restore some of these lost minerals as it's neutralizing acid. This re-mineralization re-strengthens enamel against tooth decay.
Saliva is so important for maintaining a healthy mouth, it's worth your efforts to protect it. Diminished saliva production not only produces an unpleasant dry mouth, it may increase your risk for disease. If this is a constant problem, speak to your dentist about causes and remedies. You'll be doing your teeth and gums a favor.
