Fixed Bridge

If you fail to replace an extracted tooth with a false tooth, it is possible to lose all of your teeth. If you have any concerns or further questions, feel free to contact Agoka Dental in Tampa, Florida.


Each tooth consists of two parts: the crown and root(s).

Only the crown is visible in the mouth. The roots are in the bone, under the gums.

The gums are a protective types of skin that clings to the necks of the teeth and covers the bone holding the teeth.

Molars are back teeth .They have two or three roots. Most other teeth have one root.

Losing Teeth "Two-for-One"

Recent extraction of a lower molar has created space X . Upper tooth 6 is now useless because it no longer has a tooth to chew against.

Therefore, losing one tooth can result in the loss of the use of two. Losing two teeth can result in the loss of use of four, and so on.


Back teeth have a lifetime tendency to erupt (move farther into the mouth). Only the presence of tooth to chew against keeps a back tooth from over-erupting.

This patient had a tooth extracted from space X. Upper tooth 6 has overerupted.

The resulting unevenness among the upper back teeth has created areas between these teeth that trap debris. It is very difficult to keep spaces between uneven teeth clean, despite your best efforts at brushing and flossing.

Unclean teeth usually causes inflammation of the surrounding gums. They decay more readily too.

Lower moral 7 is jamming food in between overerupted upper 6 and 7 during eating (arrow).

This pressure between upper 6 and 7 has caused upper 7 to move backward and separate slightly from upper 6. It has created a space between these teeth (arrow). Food can pack into this space with great force during chewing. This creates a serious inflammation of the gum.

Note that overeruption of upper 6 has caused some of its root to become exposed. Exposed root decays faster than the crown of a tooth, as we will see later.

Tilt And Drift

Back teeth have a lifetime tendency to tilt (lean over) toward the front of the mouth. They also have the potential to drift (move) toward the front of the mouth.

Now that a tooth has been extracted from position X, a space is left. This allows lower molar 7 to tilt and drift forward.

Lower 7 will tilt farther and farther over as you chew on it.

Gum Pocket Formation

A tooth tilted over will develop a gum pocket along its forward root, as shown here.

Gum pockets are narrow, abnormal spaces or clefts that develop between the gums and the tooth root. These pockets trap food debris and bacteria.

A gum pocket is a problem because you can almost never keep it clean, even with the best brushing and flossing.

The debris and bacteria that collect in a pocket lead to ever-worsening inflammation of the gums adjacent to the pocket.

Loss of Bone Supporting The Tooth

When an area of the gums is constantly inflamed, as you see in this gum pocket, the bone immediately adjacent to it can become inflamed too. Inflamed bone softens, and slowly begins to dissolve.

This process of gum inflammation and loss of the bone holding a tooth is called periodontal disease.

Destruction Spreads

Lower molar 7 has drifted and tilted so far forward that upper 7 no longer bites on it. This allows upper 7 to overerupt too. Arrows ( ? ) show Decay has begun on upper teeth 6 and 7, particularly on the exposed portions of the roots of 6 and 7. Exposed portion of the roots of 6 and 7. Exposed roots are especially prone to decay.advancing gum pockets, gum inflamation, and bone loss.

Both upper molars are deeply decayed. Decay has also started on lower 7.

Periodontal disease - gum pockets, gum inflamation, and loss of bone - continues to worsen.

Deep decay has allowed bacteria to enter and infect the pulps ("nerves") of upper 6 and 7. These two teeth have abscessed (become seriously infected). They are so badly damaged by decay that they must be extracted.

Because of inflammation from the gum pocket of lower 7, bone loss (outlined by arrows) has spread around the front root of this tooth and extended to part of the back root too. This tooth has lost so much bone support that it is now loose and must be extracted.

Because all the molars on this side of the mouth have been removed, the uppper and lower 5s have no support behind them and are forced backward by the action of chewing.

Food jams between the separated teeth (arrow). Gum inflamation has begun. Gum pockets will follow, along with bone loss and decay. Eventually the 5s will have to be extracted.

After the loss of the upper and lower 5s, the destructive process can move farther forward. The front teeth will start to spread apart, gum pockets will form, and decay will begin.

Now you may lose your front teeth too.


Failure to replace a single molar tooth may start a chain of events : overeruption, tilt, drift, gum pockets, decay, bone loss. Over the years this chain of events can lead to the loss of all of your teeth.

Inserting a false tooth today will avoid grief and greater expense tomorrow.

At Agoka Dental, We review thoroughly the condition of bone and gums of adjacent teeth and the Biomechanics in each individual mouth before recommending the Fixed Dental Bridge as a treatment of choice. If a patient is suitable for a Fixed Bridge, then we almost always prefer 'Porcelain fused to High Noble yellow Gold' as a material of choice for Fixed Dental Bridges. In our experience, this material has very low incidence of allergic reactions and well tolerated by many many patients. Once we insert these Bridges in the mouth, they appear as good as having a new set of teeth. They might even be better and stronger than your own teeth. Our Fees are reasonable so that more people may take advantage of it.
