Although teeth are quite durable, we can still lose them—even all of them—to disease or injury. The good news, though, is that we have effective ways to restore teeth after they're lost. One of these, the removable denture, has given people their teeth back for several generations. And with recent advances in technology, today's dentures are even better.
Although more advanced, today's dentures share the same basic structure as those from a century ago: prosthetic (false) teeth set in a plastic resin colored to resemble the gums. The traditional denture is molded to fit snugly over an individual patient's alveolar jaw ridges, which once supported the former natural teeth. The denture stays in place primarily through a suction effect between the denture and the ridges.
Modern technology, though, has greatly improved today's dentures. Digital imaging can be used to generate highly accurate impressions of the dental ridges that can lead to denture bases with better fit. Dentists using photographs of the patient, especially in earlier years, are better able to identify facial landmarks, which enables them to position the new teeth to more closely recreate the patient's former smile.
These technological aids now help dentists to create more attractive dentures with better support and comfort. But the fit that makes this possible may not last due to a particular weakness inherent in traditional dentures—continuing bone loss. When teeth are missing, the underlying jawbone can lose bone volume over time. Dentures don't stop this process and can accelerate it due to constant friction and pressure on the dental ridges.
But a new modification incorporating dental implants with dentures can help solve these problems. By placing a few strategically positioned implants in the jawbone that then connect with the denture, the appliance not only gains more stability, but also produces less pressure on the dental ridges. In addition, bone cells naturally grow and adhere to the titanium implant posts, which helps to stop or slow bone loss.
If you've experienced total tooth loss, dentures are an affordable and effective option. Thanks to modern dental advances, you can get back the smile and dental function you once lost.

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.
