A fair number of people with total tooth loss have arrived at this point after a long history of dental issues. It's quite likely they've had a series of bridges or partial dentures over the years to accommodate lost teeth at various times before moving to full dentures.
For many, it often seems easier to extract any remaining teeth at some point and simply move on to a total restoration. It's often better for oral health, however, to preserve any remaining teeth for as long as possible and update restorations as needed. Dental implants could make this type of staged restoration strategy much easier to manage.
Implants are tiny metal posts surgically imbedded in a patient's jawbone. Over time, bone cells grow and adhere to the implant's titanium surface, creating a strong and durable hold. Its most familiar application is as a replacement for an individual tooth.
But because of their strength and durability, this advanced dental technology is also used to support other restorations like bridges and partial or full dentures by way of a few strategically placed implants. And it's in that role that they can be useful in planning and implementing future restoration upgrades when needed.
Under this strategy, we add implants to supplement pre-existing implants from earlier restorations to support the updated dental work. For example, we might have previously placed an implant supporting a single tooth or a small bridge. When the need later arises for a partial denture, we can add additional implants to be used with the earlier one to support the new denture.
If the earlier implants have been well-placed, we need only to add enough implants necessary to support a full denture when the time comes. How many will depend on the particular type of denture: A removable lower denture may only require one additional implant with one already in place. A fixed upper or lower denture will require enough to bring the number to between four and eight.
Taking this long-term approach can be more cost-effective in the long-run. More importantly, it can make for a smoother path for the patient and help preserve remaining teeth for as long as possible.

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.

The subject of allergies covers a wide swath in medicine. Among other things, people have allergic reactions to animal fur, various foods and plant pollen. The effects are equally wide-ranging, anything from a mild rash to anaphylaxis, a life-threatening shutdown of the body's vital systems.
Approximately 5% of people are also allergic to various metals including nickel, cobalt, chromium and gold. Reactions to metal can occur when an allergic person comes in contact with items like jewelry, clothing or even mobile phones. There's even a chance of a metal allergy reaction from certain kinds of dental work.
It's unlikely, though, that you should be concerned if you're considering dental treatment or cosmetic work to upgrade your smile. Although allergic reactions like inflammation or a rash have been known to occur with amalgam “silver” fillings, it's quite rare. It's even less of a concern since “tooth-colored” materials for fillings are now outpacing the use of amalgam fillings, which are used in out-of-sight back teeth.
Of course, metal is used for other dental treatments besides fillings, including the most popular of tooth replacement systems, dental implants. An implant is essentially a metal post, usually made of pure titanium or a titanium alloy, which is imbedded into the jawbone. Even so, there's little chance you'll develop an allergic reaction to them.
For one thing, titanium is highly prized in both medical and dental treatments because of its biocompatibility. This means titanium devices like prosthetic joints and implants won't normally disrupt or cause reactions with human tissue. Titanium is also osteophilic: Bone cells readily grow and adhere to titanium surfaces, a major reason for dental implants' long-term durability.
That's not to say titanium allergies don't exist, but their occurrence is very low. One recent study detected a titanium allergy in only 0.6% of 1,500 implant patients who participated.
At worst, you may need to consider a different type of tooth replacement restoration in the rare chance you have a titanium allergy. More than likely, though, you'll be able obtain implants and enjoy the transformation they can bring to your smile.
