Dental Crown
Options to replace a missing tooth
Tooth loss can happen to anybody for a multitude of reasons. Teeth get worn down, chipped or cracked. Tooth loss is sometimes due to physical injury, but is more often due to prolonged periodontal or gum disease. Replacing missing teeth is important not just so that you look and feel better, but because failing to do so can be detrimental to your health. Below is a list of options available to those suffering tooth loss.
A fixed Bridge
What is a Dental Bridge?
A dental bridge, as the name implies, literally “bridges” the space between teeth that results from a missing tooth. Therefore, the restoration needs anchoring to one or more neighboring teeth, which your dentist will have to file down so they can function as a support.
Bridges don’t replace your tooth root like implants. Instead, they use one or more of your surrounding teeth as a buttress for attaching a crown that fills the space of the missing tooth. A dental bridge can replace between one and four teeth, depending on the patient’s needs. It can replace more than four teeth in some rare cases, but there must be enough healthy teeth present to connect the dental crowns.
Here are some advantages of dental bridges.
- Density: Jawbone density is not a problem.
- Nonsurgical: You won’t require surgery.
- Price: It’s less costly.
- Less invasive: You can easily replace a tooth that has been missing for a while.
- Fast: Bridges are faster to place than implants.
Dental Bridge Cons
Here are some of the downsides of dental bridges.
- Jawbone deterioration: They don’t replace the root of your tooth, thereby causing the jawbone to degenerate more quickly.
- Affects neighboring teeth: The crowned teeth neighboring the space can be more vulnerable to decay. Placement of the bridge also requires the removal of significant parts of the teeth neighboring the missing tooth or teeth.
- Short lifespan: A bridge usually only lasts eight to 15 years before you will need to get it replaced.
Removable partial denture
Most spaces can be filled with a removable denture. The primary advantage of this option is the reduced cost compared to that of bridgework or implants. The procedure is also less invasive and reversible. The difficulties that come with dentures tend to be many. Many people who wear partial dentures say they are reluctant to smile or laugh in public because they are afraid their denture may slip, or that the wires may show. They can impact the ability to eat what you like. Removable partial dentures can increase the build-up of plaque around the supporting teeth, which can lead to tooth decay or gum disease. Pressure or movement of the partial can result in trauma to the surrounding teeth or gums. Just like bridges, dentures do nothing to prevent loss of bone in the jaw.
A Dental Implant
Rather than resting on the gum line like removable dentures, or using adjacent teeth as anchors like fixed bridges, dental implants are a long-term replacement for missing teeth. They look, feel and function most like a natural tooth, mostly because they are fixed in place. Dental implants, if properly maintained, can last a lifetime.
In the case of implants, the positive tend to outweigh the negative. No healthy teeth are damaged as part of implant treatment. Not only is the gap left by the missing tooth filled, so is the root. The implant integrates with the jawbone and the implant and crown perfectly mimic the function of a natural tooth.
One disadvantage is the length of the treatment. Often, the implant is placed and there is a waiting period of 1-3 months before applying the crown, so that the implant can fuse with the bone. Another drawback is cost. However, a dental implant is a one time cost and it preserves the other healthy teeth, gum and bone in your mouth. The other options may need to be replaced once or twice in a lifetime and can cause further damage. In the end, the other options may wind up to be costlier.
Consequences of not replacing a missing tooth
Teeth are arranged in the jaw in such a manner so that they support one another and withstand the chewing forces together as a team. When one is lost without being replaced, teeth begin to move out of position and alignment However, the instability that occurs with dental collapse happens over a period of time. The signs are not as obvious and damage is often taking place silently.
Supraeruption (Over-eruption)
When an opposing lower tooth is lost and not replaced it’s upper partner now has no opposition and begins to adapt to this new space by moving downward. In doing so, it loses contact with its neighbouring teeth on either side and begins to bite more heavily with the teeth in the opposing lower arch. The bite lost its ability to distribute an equal force among all the teeth, and this can cause headaches, jaw tension, root exposure, tooth breakage, grinding, clenching and wear.
Tipping
When a tooth is lost and not replaced, the bone shrinks in the space and the teeth on either side now have a vacant area in which to tip and move into. In doing so, they lose contact with their other adjacent teeth.
Loss of Contact
Teeth are designed to touch one another to prevent food impaction that can damage tissue and cause cavities.
Plaque and Food Impaction
Aside from the first space that was created by the missing tooth, more spaces begin to develop as adjacent and opposing teeth begin to move out of their original positions. Plaque and food accumulation leads to cavities, gum and bone destruction and gum disease.
Bone Loss
When a tooth is removed there is no longer the need for bone and it resorbs (shrinks) away. Healthy, dense bone is an important factor when considering the placement of implants for replacement. The longer you leave the space, the smaller the height and width of the bone becomes
Tooth Decay
With increased food impaction comes a higher incidence of tooth decay.
Sinus Collapse
When an upper tooth is removed, over time, the floor of the sinus begins to collapse into the space where the tooth root used to occupy interfering with the space needed for a future dental implant.
Teeth sensitivity
The root of the tooth is covered with a tissue that is much less calcified and more sensitive than enamel. As a tooth moves out of its position when it over-erupts or tips, more of the root tissue will become exposed. Patients often notice more sensitivity to hot and cold sensations
TMJ
An uneven bite can quickly become a TMJ issue. Clicking, popping jaw joints, grating sounds, pain in the cheek muscles and uncontrollable jaw or tongue movements are common side effects of the missing teeth.
