Teeth Whitening

Who doesn't like a bright smile? An assortment of teeth-whitening systems is available, including toothpastes, over-the-counter gels, strips and trays, and whitening agents obtained from a dentist. But whitening isn't for everyone. It's ideal for people who have healthy, unrestored teeth and gums. Individuals with yellow tones to their teeth -- as opposed to gray tones -- respond best. Talk to your dentist to find out if whitening is right for you.


Smile Makeovers

A combination of dental techniques can be used to achieve a great smile. Here, porcelain veneers and crowns correct crooked teeth, an uneven gum line, and other chipped, worn, and discolored dentistry. While cosmetic dentists can make a dramatic difference in a person's smile and overall oral health, the work must be carefully planned. 

Gum Grafts

Tooth roots that are exposed due to gum recession may be sensitive to hot and cold foods or liquids, and they make teeth appear long. Gum recession can put you at risk of developing a cavity on the tooth root, and may lead to bone loss, eventually resulting in tooth loss. Soft tissue grafts, which move healthy gum tissue from one part of the mouth to another, can stop gum recession and bone loss and improve the esthetics of the gum line.

Enamel Shaping

Enamel shaping or contouring is a quick and painless process of shaping natural teeth to improve their appearance. It is generally used to correct small imperfections such as uneven teeth or teeth that are slightly overcrowded. Results can be seen immediately. Enamel shaping is often combined with whitening, veneers, or bonding. 

Veneers

Veneers are wafer-thin, custom-made shells that cover the front surface of teeth. Bonded to the front of the teeth, changing their color, shape, size or length, veneers can be made from porcelain or resin composite. Veneers offer a conservative approach to changing a tooth's color or shape compared to crowns, but the process is not reversible. w Paragraph

Implants

Millions of Americans suffer tooth loss, mostly due to tooth decay, gum disease, or injury. Dental implants -- replacement tooth roots which are made of titanium (shown at far left) -- provide a strong foundation for the attachment of permanent or removable artificial teeth (crowns). Instead of individual crowns, some patients may have attachments on their implant that support a removable denture. 

Composite Fillings

Existing fillings sometimes need to be replaced due to wear, chipping, or cracking. Many people use this opportunity to replace their silver amalgam fillings with natural, tooth-colored composites. Their reasons may be aesthetic, or concern over the safety of amalgam fillings, which contain mercury. Composite fillings tend to wear out sooner than silver fillings in larger cavities, although they hold up as well in small cavities.

Root Canal

Root canal therapy is a treatment used to repair and save a tooth that is badly decayed or infected.

Root canal therapy is performed when the pulp which is composed of nerves and blood vessels in the tooth becomes infected or damaged. During root canal therapy, the pulp is removed, and the inside of the tooth is cleaned and sealed.

People fear root canals because they assume they are painful. Actually, most people report that the procedure itself is no more painful than having a filling placed. The discomfort experienced in the period leading up to seeking dental care is truly painful, not the procedure itself.

The pulp or pulp chamber is the soft area within the center of the tooth and contains the nerve, blood vessels, and connective tissue. The tooth's nerve is in the "root" or "legs" of the tooth. The root canals travel from the tip of the tooth's root into the pulp chamber.

A tooth's nerve is not vitally important to a tooth's health and function after the tooth has emerged through the gums. Its only function is sensory -- to provide the sensation of heat or cold. The presence or absence of a nerve will not affect the day-to-day functioning of the tooth.

Why Does the Pulp Need to Be Removed?

When pulp is damaged, it breaks down, and bacteria begin to multiply within the pulp chamber. The bacteria and other dying pulp remnants can cause an infection or abscessed tooth. An abscess is a pus-filled pocket that forms at the end of a tooth’s root. In addition to an abscess, an infection in the root canal of a tooth can cause:

Swelling that may spread to other areas of the face, neck, or head
Bone loss around the tip of the root
Drainage problems extending outward from the root. A hole can occur through the side of the tooth, with drainage into the gums or through the cheek into the skin.

What Damages a Tooth's Pulp in the First Place?

A tooth's pulp can become irritated, inflamed, and infected due to deep decay, repeated dental procedures on a tooth, large fillings, a crack or chip in the tooth, or trauma to the face.

What Are the Signs That Root Canal Therapy Is Needed?
Signs you may need root canal therapy include:

Severe toothache pain upon chewing or application of pressure
Prolonged sensitivity (pain) to hot or cold temperatures (after the heat or cold has been removed)
Discoloration (darkening) of the tooth
Swelling and tenderness in nearby gums
A persistent or recurring pimple on the gums
Sometimes no symptoms are present.

The first step in the procedure is to take an X-ray to see the shape of the root canals and determine if there are any signs of infection in the surrounding bone. Your dentist or endodontist will then use local anesthesia to numb the area near the tooth. Actually, anesthesia may not be necessary, since the nerve is dead, but most dentists still anesthetize the area to make the patient more relaxed and at ease.

Next, to keep the area dry and free of saliva during treatment, your dentist will place a rubber dam (a sheet of rubber) around the tooth.

An access hole will then be drilled into the tooth. The pulp, along with bacteria and related debris, is removed from the tooth. The cleaning-out process is accomplished using root canal files. A series of these files of increasing diameter are each subsequently placed into the access hole and worked down the full length of the tooth to scrape and scrub the sides of the root canals. Water or sodium hypochlorite is used periodically to flush away the debris.

Once the tooth is thoroughly cleaned, it needs to be sealed. Some dentists like to wait a week before sealing the tooth. For instance, if there is an infection, your dentist may put a medication inside the tooth to clear it up. Others may choose to seal the tooth the same day it is cleaned out. If root canal therapy is not completed on the same day, a temporary filling is placed in the exterior hole in the tooth to keep contaminants out between appointments.

At the next appointment, to fill the interior of the tooth, a sealer paste and a rubber compound called gutta-percha are placed into the tooth's root canal. To fill the exterior access hole created at the beginning of treatment, a filling is placed.

The final step may involve further restoration of the tooth. Because a tooth that needs root canal therapy often is one that has a large filling or extensive decay or other weakness, a crown, crown and post, or other restoration often needs to be placed on the tooth to protect it, prevent it from breaking, and restore it to full function. Your dentist will discuss the need for any additional dental work with you.

Root canal therapy should relieve the pain you feel. Until your root canal procedure is completely finished -- that is, the permanent filling is in place and a crown, if needed, is in place -- it's wise to minimize chewing on the tooth under repair. This step will help avoid recontaminating the tooth’s interior and also may prevent a fragile tooth from breaking before the tooth can be fully restored.

For the first few days following the completion of treatment, the tooth may feel sensitive due to natural tissue inflammation, especially if there was pain or infection before the procedure. This sensitivity or discomfort usually can be controlled with over-the-counter pain medications such as ibuprofen (Advil, Motrin) or naproxen (Aleve). Most patients can return to their normal activities the next day.

Because the final step of root canal therapy is application of a restoration such as a crown or a filling, it will not be obvious to onlookers that a root canal was performed.

Root canal treatment is highly successful; the procedure has more than a 95% success rate. Many teeth fixed with root canal therapy can last a lifetime.

Alternatives to Root Canal Therapy
Saving your natural teeth is the very best option, if possible. Your natural teeth make it possible for you to eat a wide variety of foods necessary to maintain proper nutrition. Root canal therapy is the treatment of choice.

The only alternative to a root canal procedure is having the tooth extracted. The tooth would then be replaced with a bridge, implant, or removable partial denture to restore chewing function and prevent adjacent teeth from shifting. These alternatives not only are more expensive than a root canal procedure but require more treatment time and additional procedures to adjacent teeth and supporting tissues.

The fees charged by endodontists could be up to 50% higher.
