Wisdom Teeth Extractions
Third molars, commonly referred to as wisdom teeth, are usually the last four of 32 teeth to erupt (surface) in the mouth, generally making their appearance between the ages of 17 to 25. They are located at the back of the mouth (top and bottom), near the entrance to the throat. The term “wisdom” stems from the idea that the molars surface at a time typically associated with increased maturity or “wisdom”.
In most cases, inadequate space in the mouth does not allow the wisdom teeth to erupt properly and become fully functional. When this happens, the tooth can become impacted (stuck) in an undesirable or potentially harmful position. If left untreated, impacted wisdom teeth can contribute to infection, damage to other teeth, and possibly cysts or tumors.
There are several types, or degrees, of impaction based on the actual depth of the teeth within the jaw:
Soft Tissue Impaction: The upper portion of the tooth (the crown) has penetrated through the bone, but the gingiva (gum) is covering part or all of the tooth’s crown and has not positioned properly around the tooth. Because it is difficult to keep the area clean, food can become trapped below the gum and cause an infection and/or tooth decay, resulting in pain and swelling.
Partial Bony Impaction: The tooth has partially erupted, but a portion of the crown remains submerged below the gum and surrounding jawbone. Again, because it is difficult to keep the area clean, infection will commonly occur.
Complete Bony Impaction: The tooth is completely encased by jawbone. This will require more complex removal techniques.
Reasons to Remove Wisdom Teeth
While not all wisdom teeth require removal, wisdom teeth extractions are most often performed because of an active problem such as pain, swelling, decay or infection, or as a preventative measure to avoid serious problems in the future. If impaction of one or more wisdom teeth is present, and left untreated, a number of potentially harmful outcomes can occur, including:
- Damage to Nearby Teeth: Second molars (the teeth directly in front of the wisdom teeth) can be adversely affected by impacted wisdom teeth, resulting in tooth decay (cavities), periodontal disease (gum disease) and possible bone loss.
- Disease: Although uncommon, cysts and tumors can occur in the areas surrounding impacted wisdom teeth.
- Infection: Bacteria and food can become trapped under the gum tissue, resulting in an infection. The infection can cause considerable pain and danger.
- Tooth Crowding: It has been theorized that impacted wisdom teeth can put pressure on other teeth and cause them to become misaligned (crowded or twisted). This theory isn’t universally accepted by all dental professionals, and it has never been validated by any scientific studies.
Wisdom Teeth Examination
As with any dental procedure, your dentist will want to initially conduct a thorough examination of the wisdom and surrounding teeth. Panoramic or digital X-rays will be taken in order for your dentist to evaluate the position of the wisdom teeth and determine if a current problem exists, or the likelihood of any potential future problems. The X-rays can also expose additional risk factors, such as deterioration or decay of nearby teeth. Early evaluation and treatment (typically in the mid-teen years) is recommended in order to identify potential problems and to improve the results for patients requiring wisdom teeth extractions. Only after a thorough examination can your dentist provide you with the best options for your particular case.
What does the removal of wisdom teeth involve?
Wisdom teeth removal is a common procedure, generally performed under local anesthesia, intravenous (IV) sedation, or general anesthesia by a specially trained dentist in an office surgery suite. The surgery does not require an overnight stay, and you will be released with post-operative instructions and medication (if necessary), to help manage any swelling or discomfort.
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:
- Periodontal Disease: Periodontal disease can affect and permanently damage the jaw bone that supports the teeth. Affected areas progressively worsen until the teeth become unstable.
- Tooth Extraction: Studies have shown that patients who have experienced a tooth extraction subsequently lose 40-60% of the bone surrounding the extraction site during the following three years. Loss of bone results in what is called a “bone defect”.
- Injuries and Infections: Dental injuries and other physical injuries resulting from a blow to the jaw can cause the bone to recede. Infections can also cause the jaw bone to recede in a similar way.
Reasons for Bone Grafts
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.
Dental implants are a great way to replace missing teeth and also provide a fixed solution to having removable partial or complete dentures. Implants provide excellent support and stability for these dental appliances.
Dental implants are artificial roots and teeth (usually titanium) that are surgically placed into the upper or lower jaw bone by a dentist or Periodontist – a specialist of the gums and supporting bone. The teeth attached to implants are very natural looking and often enhance or restore a patient’s smile!
Dental implants are strong and durable and will last many years. On occasion, they will have to be re-tightened or replaced due to normal wear.
Reasons for dental implants:
- Replace one or more missing teeth without affecting adjacent teeth.
- Resolve joint pain or bite problems caused by teeth shifting into missing tooth space.
- Restore a patient’s confident smile.
- Restore chewing, speech, and digestion.
- Restore or enhance facial tissues.
- Support a bridge or denture, making it more secure and comfortable.
What does getting dental implants involve?
The process of getting implants requires a number of visits over several months.
X-rays and impressions (molds) are taken of the jaw and teeth to determine bone, gum tissue, and spacing available for an implant. While the area is numb, the implant will be surgically placed into the bone and allowed to heal and integrate itself for up to six months. Depending on the type of implant, a second surgery may be required in order to place the “post” that will hold the artificial tooth in place. With other implants the post and anchor are already attached and placed at the same time.
After several weeks of healing the artificial teeth are made and fitted to the post portion of the anchor. Because several fittings may be required, this step may take one to two months to complete. After a healing period, the artificial teeth are securely attached to the implant, providing excellent stability and comfort to the patient.
You will receive care instructions when your treatment is completed. Good oral hygiene and eating habits, alongside regular dental visits, will aid in the life of your new implant.

Sleep apnea is a potentially life-threatening sleep disorder characterized by repeated pauses in breathing during sleep. The term sleep apnea is derived from the Greek etymology meaning “without breath”. Breathing pauses can last anywhere from several seconds to minutes, and happen as often as 30 times or more per hour. Ongoing disrupted breathing causes an imbalance between the carbon dioxide and oxygen levels in the bloodstream, as not enough carbon dioxide is exiting and not enough oxygen is entering the body.
Sensing this imbalance, the brain sends a message to the body, telling it to wake up to restart the breathing process. People with sleep apnea will partially awake as they struggle to breathe, and this is often accompanied by loud snoring or choking sensations. Because people with sleep apnea don’t always completely awake during the episodes, they are often unaware they have a sleeping disorder and it can remain undiagnosed.
There are two main types of this disorder; central sleep apnea which occurs when the brain fails to send important signals to the breathing muscles, and obstructive sleep apnea which occurs when air cannot flow through the nose or mouth even though the body is still trying to breathe. Obstructive sleep apnea is far more prevalent and easily treatable by the dentist.
Common signs of obstructive sleep apnea can include severe early morning headaches, sleepiness in the daytime, and insomnia. Fortunately, the dentist is equipped with the necessary technology and expertise to treat sleep apnea in several different ways.
Reason for Treating Sleep Apnea
It is very important to seek medical attention if sleep apnea is suspected. A sufferer can completely stop breathing numerous times per hour, and this can quickly turn into a deadly situation. Obstructive sleep apnea occurs when the soft tissue lying at the back of the patient’s throat collapses into the airway. The tongue then falls towards the back of the throat which tightens the blockage and prevents oxygen from entering the lungs.
The problem worsens when the chest region, diaphragm, and abdomen fight for air. The efforts they make to obtain vital oxygen only cause a further tightening of the blockage. The patient must arouse from deep sleep to tense the tongue and remove the soft tissue from the airway.
Because sleep apnea causes carbon dioxide levels to skyrocket in the blood and oxygen levels to decrease, the heart has to pump harder and faster to compensate for the lack of oxygen. Sleep apnea patients can technically “die” many times each night. Sleep apnea has been linked to a series of serious heart-related conditions, and should be investigated at the earliest opportunity.
TMJ (Temporomandibular Joint Dysfunction)
Temporomandibular Joint Dysfunction Syndrome (TMJ) is a common condition affecting a wide variety of people. TMJ is characterized by severe headaches, jaw pain of varying degrees, grinding teeth, and an intermittent ringing in the ears. The vast majority of TMJ sufferers are unaware that the root cause of these problems is something that a dentist can effectively treat.
The symptoms of TMJ are debilitating and can greatly interfere with every day life. The comfort and general well being of the patient is at the heart of the dental practice, so pain relief is the first consideration of the dentist. The dentist is able to test, diagnose, and devise an immediate plan to treat the underlying causes of the TMJ disorder.
Reasons for treating TMJ
TMJ sufferers report that their symptoms generally worsen during periods of prolonged or unexpected stress, and that intense outbreaks of the condition can lead to neck pain and dizziness.
The most common cause of TMJ is the misalignment of the teeth, often called “bad bite.” It is possible for the dentist to realign or adjust the teeth without the need for painful or expensive surgeries. The realignment/adjustment will stop the pounding headaches, the jaw pain, and the dizziness.
The grinding teeth symptom is particularly common and usually occurs at night. The grinding will eventually erode the structure of the teeth and lead to much more severe dental problems in the future. Untreated TMJ is one of the prime underlying factors in eroded jawbones and loose teeth.
It is important for anyone experiencing the symptoms of TMJ to visit the dentist for an exact diagnosis.
What does treating TMJ involve?
TMJ could be a result of several different problems. Bad bite is the most common, but an injury resulting from a blow to the meniscus cartilage is also a possibility. Initially, the dentist will thoroughly examine the jaw area, the patient’s bite, take X-rays, and review the patient’s history in order to make an accurate diagnosis and recommend necessary treatment.
Once a firm diagnosis is attained, there are several ways in which relief can be provided. A specially molded bite guard can be created to stop teeth grinding during the night. A bite relationship analysis may be recommended by the dentist. The dentist can also provide advice on relaxation techniques which will lessen the effects of stress. As a last alternative, the dentist is also able to prescribe muscle relaxants.
