For most people, replacing missing front teeth takes a higher priority over missing back teeth. The reason is obvious: others can see those missing in front, but not necessarily those in the back.
From a functional view, however, you should still consider replacing missing back teeth. Not only will it improve your chewing ability, it may also prevent a chain reaction of negative effects to your remaining teeth.
Teeth are held in place in the jawbone by a membrane called the periodontal ligament. The ligament is a living tissue that allows teeth to move to keep contact with adjacent and opposing teeth as natural wear occurs. When a space is created by a missing tooth, this natural movement accelerates and the teeth may shift beyond normal ranges.
As a result you can encounter excessive mobility of teeth from bite irregularities, uneven tooth wear, bone loss, potential painful problems with the temporo-mandibular joints (connecting the lower jaw to the skull), and a loss in facial height.
There are three basic options for this kind of tooth replacement. The best option is dental implants: these free-standing replacements don't normally affect surrounding teeth, they're easier to clean, and they help support the bite. On the downside, there must be enough remaining bone to support the implant.
The next best option is a fixed bridge. This option only works, however, if there are teeth on either side of the missing tooth space capable of supporting the bridge, and they must be reduced in size by removing the enamel with the dental drill. They also have a tendency to retain plaque, the main cause of gum disease.
That leaves the last, and least favorable, option, a removable partial denture. They may also trap food and be difficult to wear. They can move in the mouth, stressing — and possibly loosening — the remaining teeth that hold them in place. With all its drawbacks, though, if a partial denture is the only solution to missing back teeth, it's a better alternative than doing nothing and risking long-term problems.

Your teeth are under constant attack from bacteria that normally live in your mouth. When these bacteria thrive, they create acid that begins to dissolve the minerals in your enamel (the outer layer of your teeth). In your defense, your saliva protects against these bacteria and adds minerals back to your enamel. Let's take a look at this ongoing battle, and what you can do to sway it in a positive direction.
The outer covering of your teeth, the enamel, is made mainly of the minerals calcium and phosphate. The enamel protects the interior layer of your teeth, the dentin, which is similar in composition to bone. Although it is the hardest substance in your body, the enamel is still vulnerable to attack.
Your mouth is normally full of saliva, which washes over your teeth and maintains a balance between acids and bases. The terms “acids” and “bases” refer to a scientific measurement, the pH scale. Your mouth's pH is usually in the middle of the scale — neither acidic nor basic, but neutral. This is important in controlling the bacteria in your mouth.
You may be surprised to know how many bacteria live in everyone's mouth. More bacteria live in a single mouth than the number of people who have ever lived on earth. Some of these bacteria can cause tooth decay. Let's call them “bad bacteria.”
When the bad bacteria attach themselves to dental plaque — a film that builds up on your teeth every day — they begin to consume sugars that are in your mouth from foods that you have eaten. As the bacteria break down these sugars and turn them into energy, acid is produced as a by-product. This turns the saliva from neutral to acidic.
At a certain level of acidity, minerals in your enamel start to dissolve. This is called “de-mineralization.” It means that more calcium and phosphate are leaving the tooth's surface than are entering it. Early de-mineralization of the enamel shows up as white spots on a tooth.
Fortunately, healthy saliva can return calcium and phosphate to the enamel, or re-mineralize it. De-mineralization and opposing re-mineralization are constantly battling in your mouth. However, if too much enamel is de-mineralized, bacterial acid can go on to attack the next layer of your teeth, the dentin. As this process continues, you develop a dental cavity.
How can you protect your teeth? The first level of defense is regular removal of plaque, so that the bad bacteria do not get a foothold. In an office visit we may also recommend products such as sealants, antibacterial agents, topical fluoride, calcium and phosphate supplements, pH neutralizers, special toothpaste and rinses, which may help your particular situation.
