A dental crown is a tooth-shaped “cap” that is placed over a tooth — to cover the tooth to restore its shape and size, strength, and improve its appearance.
The crowns, when cemented into place, fully encase the entire visible portion of a tooth that lies at and above the gum line.
Why Is a Dental Crown Needed?
A dental crown may be needed in the following situations:
- To protect a weak tooth (for instance, from decay) from breaking or to hold together parts of a cracked tooth.
- To restore an already broken tooth or a tooth that has been severely worn down.
- To cover and support a tooth with a large filling when there isn’t a lot of tooth left.
- To hold a dental bridge in place.
- To cover misshapen or severely discolored teeth.
- To cover a dental implant.
- To make a cosmetic modification.
A bridge may be recommended if you’re missing one or more teeth. Gaps left by missing teeth eventually cause the remaining teeth to rotate or shift into the empty spaces, resulting in a bad bite. The imbalance caused by missing teeth can also lead to gum disease and temporomandibular joint (TMJ) disorders.
Bridges are commonly used to replace one or more missing teeth. They span the space where the teeth are missing. Bridges are cemented to the natural teeth or implants surrounding the empty space. As with crowns, you have a choice of materials for bridges.
Your dentist can help you decide which to use, based on the location of the missing tooth (or teeth), its function, aesthetic considerations and cost. Porcelain or ceramic bridges can be matched to the color of your natural teeth.
A denture is a removable replacement for missing teeth and surrounding tissues. Two types of dentures are available — complete and partial dentures. Complete dentures are used when all the teeth are missing, while partial dentures are used when some natural teethremain.
Reasons for Pulling Teeth:
Although permanent teeth were meant to last a lifetime, there are a number of reasons why tooth extraction may be needed. A very common reason involves a tooth that is too badly damaged, from trauma or decay, to be repaired. Other reasons include:
A crowded mouth. Sometimes dentists pull teeth to prepare the mouth for orthodontia. The goal of orthodontia is to properly align the teeth, which may not be possible if your teeth are too big for your mouth. Likewise, if a tooth cannot break through the gum (erupt) because there is not room in the mouth for it, your dentist may recommend pulling it.
Infection. If tooth decay or damage extends to the pulp — the center of the tooth containing nerves and blood vessels — bacteria in the mouth can enter the pulp, leading to infection. Often this can be corrected with root canal therapy (RCT), but if the infection is so severe that antibiotics or RCT do not cure it, extraction may be needed to prevent the spread of infection.
Risk of infection. If your immune system is compromised (for example, if you are receiving chemotherapy or are having an organ transplant), even the risk of infection in a particular tooth may be reason enough to pull the tooth.
Periodontal (Gum) Disease. If periodontal disease — an infection of the tissues and bones that surround and support the teeth — have caused loosening of the teeth, it may be necessary to the pull the tooth or teeth.
ROOT CANAL TREATMENT
Root canal treatment is done when decay will likely damage or has already killed a tooth. During a root canal, a dentist removes the pulp from the center of a tooth and fills the pulp cavity. This can prevent the development of a painful infection in the pulp that may spread to other teeth. A root canal can also treat an infection that has developed into an abscessed tooth. This procedure can relieve toothache, stop infection, and promote healing.
There are a variety of treatments for gum disease depending on the stage of disease, how you may have responded to earlier treatments, and your overall health.
Treatments range from nonsurgical therapies that control bacterial growth to surgery to restore supportive tissues.
- Professional dental cleaning.During a typical checkup your dentist or dental hygienist will remove the plaque and tartar (plaque that builds up and hardens on the tooth surface and can only be removed with professional cleaning) from above and below the gum line of all teeth. If you have some signs of gum disease, your dentist may recommend professional dental cleaning more than twice-a-year.
- Scaling and root planning.This is a deep-cleaning, whereby plaque and tartar from above and below the gum line are scraped away (scaling) and rough spots on the tooth root are made smooth (planning). Smoothing the rough spots removes bacteria and provides a clean surface for the gums to reattach to the teeth. Scaling and root planning is done if your dentist determines that you have plaque and calculus (hardened plaque, also called tartar) under the gums that needs to be removed.
Surgical Treatments for Gum Disease
Some treatments for gum disease are surgical. Some examples are:
- Flap surgery/pocket reduction surgery.During this procedure the gums are lifted back and the tarter is removed. In some cases, irregular surfaces of the damaged bone are smoothed to limit areas where disease-causing bacteria can hide. The gums are then placed so that the tissue fits snugly around the tooth. This method reduces the size of the space between the gum and tooth, thereby decreasing the areas where harmful bacteria can grow and decreasing the chance of serious health problems associated with periodontal disease.
- Bone grafts.This procedure involves using fragments of your own bone, synthetic bone, or donated bone to replace bone destroyed by gum disease. The grafts serve as a platform for the regrowth of bone, which restores stability to teeth. New technology, called tissue engineering, encourages your own body to regenerate bone and tissue at an accelerated rate.
- Soft tissue grafts.This procedure reinforces thin gums or fills in places where gums have receded. Grafted tissue, most often taken from the roof of the mouth, is stitched in place, adding tissue to the affected area.
- Guided tissue regeneration.Performed when the bone supporting your teeth has been destroyed, this procedure stimulates bone and gum tissue growth. Done in combination with flap surgery, a small piece of mesh-like fabric is inserted between the bone and gum tissue. This keeps the gum tissue from growing into the area where the bone should be, allowing the bone and connective tissue to regrow to better support the teeth.
- Bone surgery.Smooths shallow craters in the bone due to moderate and advanced bone loss. Following flap surgery, the bone around the tooth is reshaped to decrease the craters. This makes it harder for bacteria to collect and grow.
In some patients, the nonsurgical procedure of scaling and root planning is all that is needed to treat gum diseases. Surgery is needed when the tissue around the teeth is unhealthy and cannot be repaired with nonsurgical options.
