Root canal therapy is needed when the nerve of a tooth is affected by decay or infection. In order to save the tooth, the pulp (the living tissue inside the tooth), nerves, bacteria, and any decay are removed and the resulting space is filled with special, medicated, dental materials that restore the tooth to its full function.
Having a root canal done on a tooth is the treatment of choice to save a tooth that would otherwise die and have to be removed. Many patients believe that removing a tooth that has problems is the solution, but what is not realized is that extracting (pulling) a tooth will ultimately be more costly and cause significant problems for adjacent teeth.
Root canal treatment is highly successful and usually lasts a lifetime, although on occasion, a tooth will have to be retreated due to new infections.

Reasons for root canal therapy:
What does root canal therapy involve?
A root canal procedure requires one or more appointments and can be performed by a dentist or endodontist (a root canal specialist).
While the tooth is numb, a rubber dam (a sheet of rubber) will be placed around the tooth to keep it dry and free of saliva. An access opening is made on top of the tooth and a series of root canal files are placed into the opening one at a time, removing the pulp, nerve tissue, and bacteria. If tooth decay is present, it will also be removed with special dental instruments.
Once the tooth is thoroughly cleaned, it will be sealed with either a permanent filling, or if additional appointments are needed, a temporary filling will be placed.
At the next appointment, usually a week later, the roots and the inside cavity of the tooth will be filled and sealed with special dental materials. A filling will be placed to cover the opening on top of the tooth. In addition, all teeth that have root canal treatment should have a crown (cap) placed. This will protect the tooth and prevent it from breaking, restoring it to its full function.
After treatment, your tooth may still be sensitive, but this will subside as the inflammation diminishes and the tooth has healed.
You will be given care instructions after each appointment. Good oral hygiene practices and regular dental visits will aid in the life of your root canal treatment.
In rare cases, root canal therapy fails to work as expected. The treated tooth might not heal properly, or a patient might experience post-surgical complications that jeopardize the tooth. Root canal retreatment involves the removal of the previous crown and packing material, the cleansing of the root canals, and the re-packing and re-crowning of the tooth. In short, root canal retreatment is almost identical to the original procedure, aside from the structural removal. The success rate for a root canal retreatment runs at around 75%.
Root canal treatments and retreatments are a better alternative than extraction for most individuals. If a tooth has good bone support, a solid surface and healthy gums beneath it, it stands a good chance of being saved. Opting for root canal retreatment can be far less expensive than the alternatives. Dental implants, extensive bridgework, and the creation of aesthetically pleasing prosthetic teeth cost far more than working with the natural tooth. They also require maintenance and feel less natural than a “real” tooth.
Why is root canal retreatment required?
Though the prospect of more endodontic surgery might not be pleasant, root canal retreatment is fairly simple. In general, the whole treatment can be completed in 1-3 visits.
There are a number of reasons why root canal therapy unexpectedly fails, including:
What does root canal retreatment involve?
On the day of the retreatment procedure, a local anesthetic will be administered, unless another type of anesthetic has been selected. The affected tooth is isolated with a rubber dam. The dam protects the tooth during treatment from bacteria and saliva. The amount the dentist can do within a single appointment will depend on the amount of inflammation present and the complexity of the treatment.
The first step in a root canal retreatment is to gain access to the inner tooth. If a crown and post have been placed, these will be removed.
Next, filling material and obstructions that block the root canals will be removed. This removal is conducted using an ultrasonic handpiece. The advantage of using this tool is that any unwanted material is vibrated loose. Tiny instruments will then be used to clean and reshape the root canals. X-rays may be taken to ensure that the roots are thoroughly clean. If this part of the treatment proves to be complex, medicated packing material will be applied, and the rest of the cleansing procedure will be done at the next visit.
When the dentist is confident that the root canals are completely clean, gutta-percha is used to pack the space. This rubbery material seals the canals to prevent bacterial invasion. Finally, a temporary crown or filling is applied to tooth. At a later date, the color-matched, permanent crown will be placed.

Cracked and fractured teeth are common dental problems. As people retain their natural teeth longer (due to advances in dental technology), the likelihood of cracked teeth increases. There are many reasons why teeth may crack, for example, biting on hard objects, trauma, grinding and clenching of teeth. All of these behaviors place the teeth under extra strain and render them more susceptible to cracking.
When tooth enamel is cracked, pain can become momentarily debilitating. In the absence of pressure on the crack, there may be no discomfort. However, as the cracked tooth performs a biting action, the crack widens. The pulp and inner workings of the tooth then become exposed, and painful irritation occurs. As pressure is released again, the two parts of the crack fuse back together, and pain subsides. If left untreated, the pulp becomes irreversibly damaged and constantly painful. The resulting pulp infection can affect the bone and soft tissue surrounding the tooth.
Symptoms of a cracked tooth may include:
What kind of cracks can affect the teeth?
There are many ways in which a tooth can be cracked. The specific type of crack will determine what type of treatment is viable. In many cases, if the crack is not too deep, root canal therapy can be performed and the natural tooth can remain in the mouth. In other situations, the tooth is too badly damaged and requires extraction.
Here is a brief overview of some of the most common types of cracks:
Crazes – These are generally tiny vertical cracks that do not place the teeth in danger. These scratches on the surface of the teeth are considered by most dentists to be a normal part of the tooth anatomy. A craze rarely requires treatment for health reasons, but a wide variety of cosmetic treatments can be performed to reduce the negative aesthetic impact.
Oblique supragingival cracks – These cracks only affect the crown of the tooth and do not extend below the gum line. Usually, the affected part of the tooth will eventually break off. Little pain will result, because the tooth pulp (that contains the nerves and vessels) will remain unaffected.
Oblique subgingival cracks – These cracks extend beyond the gum line and often beyond where the jawbone begins. When a piece breaks off, it will usually remain attached until we remove it. Oblique subgingival cracks are painful and may require a combination of periodontal surgery (to expose the crown) and endodontic treatment to place a crown or other restorative device.
Vertical furcation cracks – These cracks occur when the roots of the tooth separate. This type of crack almost always affects the nerve of the tooth. Because the tooth will not generally separate completely, root canal therapy and a crown can usually save the tooth.
Oblique root cracks – These cracks tend not to affect the surface of the tooth at all. In fact, the damage is only apparent below the gum line and usually below the jawbone. Root canal therapy may be possible, depending on how close the fracture is to the tooth surface. However, extraction is almost always the only option after sustaining this classification of fracture.
Vertical apical root cracks – These cracks occur at the apex (tip of the root). Though the tooth does not require extraction from a dental perspective, many patients request an extraction because of the high degree of pain. Root canal therapy alleviates the discomfort for a while, but most often, teeth affected by such cracks are eventually extracted.
How are cracks in the teeth treated?
There are many different types of cracked teeth. Some can only be exposed using X-ray machines, while others are clearly visible to the naked eye. In cases where the tooth root is affected, root canal therapy is the most viable treatment option. The pulp, nerves, and vessels of the tooth will be removed, and the resulting space will be filled with gutta-percha. A crown or filling will be added to stabilize the tooth, and it will continue to function as normal.
When the crack is too severe for the tooth to be saved, we will perform an extraction. There are a number of restorative options in this case, such as bridges, dental implants and partial dentures. All of these structures can restore biting, chewing, and speaking functions.

Bone grafting is often closely associated with dental restorations such as bridge work and dental implants. In the majority of cases, the success of a restoration procedure can hinge on the height, depth, and width of the jawbone at the implant site. When the jawbone has receded or sustained significant damage, the implant(s) cannot be supported on this unstable foundation and bone grafting is usually recommended for the ensuing restoration.
There are several major factors that affect jaw bone volume:
Bone grafting is a highly successful procedure in most cases. It is also a preferable alternative to having missing teeth, diseased teeth, or tooth deformities. Bone grafting can increase the height or width of the jawbone and fill in voids and defects in the bone.
There are essentially two basic ways in which bone grafting can positively impact the health and stability of the teeth:
Jaw Stabilization – Bone grafting stabilizes and helps restore the jaw foundation for restorative or implant surgery. Deformities can also be corrected and the restructuring of the bone can provide added support.
Preservation – Bone grafting can be used to limit or prevent bone recession following a tooth extraction, periodontal disease, or other invasive processes.
Initially, the dentist will thoroughly examine the affected area in order to assess the general condition of the teeth and gums. If periodontal disease is present or the adjacent teeth are in poor condition, these factors will be fully addressed before the bone grafting procedure can begin. The dentist will also recommend panoramic x-rays in order to assess the precise depth and width of the existing bone. On occasion, a CAT scan may be recommended to determine the bone condition. Depending on these results, the dentist may also anesthetize the area and explore into the gum in order to determine what kind and how much bone is required.
There are several types of bone grafts. Your dentist will determine the best type for your particular condition.
The bone grafting procedure can often take several months to complete. Bone is typically harvested from your own body (or on rare occasions obtained from a “bone bank”) and added to the affected site. This bone will fuse with the existing bone and the migration of cells will cause firm adhesion and cell growth. Supplementing the jaw with bone will result in greater bone mass to help support and anchor the implant(s).
During the surgery, the dentist will numb the grafting and extraction sites using local anesthetic. A small incision will be made to prepare the site for the new bone and it will be anchored into place. On occasion, a synthetic membrane may be used to cover the new bone. This membrane prevents soft tissue and bacterial invasions, and encourages new bone growth. The surgery does not require an overnight stay, and you will be provided with comprehensive instructions for your post-operative care. The dentist will prescribe medications to help manage infection, discomfort and swelling.
Crown lengthening is generally performed to improve the health of the gum tissue or to prepare the mouth for restorative or cosmetic procedures. In addition, crown lengthening procedures can also be used to correct a “gummy” smile, where teeth are covered with excess gum tissue. Crown lengthening exposes more of the natural tooth by reshaping or recontouring bone and gum tissue. This treatment can be performed on a single tooth, many teeth, or the entire gum line, exposing an aesthetically pleasing smile.
Reasons for crown lengthening
Crown lengthening is a versatile and common procedure that has many effective uses and benefits. The vast majority of patients who have undergone this type of surgery are highly delighted with the results.
Here are some of the most common reasons for crown lengthening:
What does crown lengthening involve?
Crown lengthening is normally performed under local anesthetic. The amount of time this procedure takes will largely depend on how many teeth are involved and whether a small amount of bone needs to be removed along with the soft tissue. Any existing dental crowns will be removed prior to the procedure and replaced immediately afterwards.
The dentist will make a series of small incisions around the soft tissue in order to separate the gums away from the teeth. Even if only one tooth requires the re-contour, neighboring teeth are usually treated to provide a more even reshaping. Separating the gums provides the dentist with access to the roots of the teeth and the underlying bone.
In some cases, the removal of a small amount of tissue will provide enough tooth exposure to place a crown. In other cases, the dentist will also need to remove a small amount of bone from around the teeth. The bone is usually removed using a combination of special hand instruments, and rotary instruments. The rotary instruments roughly resemble the drill that is used in cavity treatment.
When the dentist is satisfied that the teeth have sufficient exposure, the wound will be cleaned with sterile water, and the gum tissue will be sutured with small stitches. The teeth will look noticeably longer immediately after surgery because the gums will have been repositioned.
The dentist will secure the surgical site using an intraoral (periodontal) bandage which serves to prevent infection. Prescriptions may be provided for pain medication, and a chlorhexidine (antimicrobial) mouth rinse may be given to help reduce any bacteria attempting to re-colonize. The surgical site will be completely healed in approximately two to three months.

Primary teeth, also known as “baby teeth” or “deciduous teeth,” begin to develop beneath the gums during the second trimester of pregnancy. Teeth begin to emerge above the gums approximately six months to one year after birth. Typically, preschool children have a complete set of 20 baby teeth – including four molars on each arch.
One of the most common misconceptions about primary teeth is that they are irrelevant to the child’s future oral health. However, their importance is emphasized by the American Dental Association (ADA), which urges parents to schedule a “baby checkup” with a pediatric dentist within six months of the first tooth emerges.
What are the functions of primary teeth?
Primary teeth can be painful to acquire. To soothe tender gums, biting on chewing rings, wet gauze pads, and clean fingers can be helpful. Though most three-year-old children have a complete set of “baby” teeth, eruption happens gradually – usually starting at the front of the mouth.
The major functions of baby teeth are described below:
Speech production and development – Learning to speak clearly is crucial for cognitive, social, and emotional development. The proper positioning of primary teeth facilitates correct syllable pronunciation and prevents the tongue from straying during speech formation.
Eating and nutrition – Children with malformed or severely decayed primary teeth are more likely to experience dietary deficiencies, malnourishment, and to be underweight. Proper chewing motions are acquired over time and with extensive practice. Healthy deciduous teeth promote good chewing habits and facilitate nutritious eating.
Self-confidence – Even very young children can be quick to point out ugly teeth and crooked smiles. Taking good care of primary teeth can make social interactions more pleasant, reduce the risk of bad breath, and promote confident smiles and positive social interactions.
Straighter smiles – One of the major functions of primary teeth is to hold an appropriate amount of space for developing adult teeth. In addition, these spacers facilitate the proper alignment of adult teeth and also promote jaw development. Left untreated, missing initial teeth cause the remaining teeth to “shift” and fill spaces improperly. For this reason, pediatric dentists often recommend space-maintaining devices.
Excellent oral health – Badly decayed baby teeth can promote the onset of childhood periodontal disease. As a result of this condition, oral bacteria invade and erode gums, ligaments, and eventually bone. If left untreated, they can drop out completely – causing health and spacing problems for emerging permanent teeth. To avoid periodontal disease, children should practice an adult-guided oral care routine each day, and infant gums should be rubbed gently with a clean, damp cloth after meals.
