“Impacted wisdom teeth.” The term alone sounds ominous. What are wisdom teeth, why do they become impacted, what is the best way to treat them? These are questions people often ask.
What are “wisdom teeth” anyway?
Your third molars, located in the very back of your jaws, are your wisdom teeth. Most people have four of them.
Why is their name associated with wisdom?
They usually begin to come in when a person is 17 to 25 years old, a time when he or she can be said to begin to reach an age of wisdom.
Doesn't everyone get wisdom teeth?
While some people have more than four, others have fewer, and some have no wisdom teeth at all. Some people have wisdom teeth that can be seen in x-rays but do not erupt (grow up through their gums) and become visible.
What does “impacted” mean?
In normal usage, the term “impact” means “influence or effect.” In dental vocabulary, it means that a tooth is affecting another tooth or a nearby structure such as gums, nerves or blood vessels. Often an impacted wisdom tooth grows sideways into an adjacent tooth instead of growing upwards to come through the gums normally. This may be caused by a lack of room in your jaw for your third molars.
What kinds of problems can impacted wisdom teeth cause?
A wisdom tooth can impact the gum tissues surrounding nearby molars, leading to infection called “periodontal disease” (from the root words for “around” and “tooth.”) They can also cause root resorption in adjacent teeth, a process by which the tooth’s roots are slowly dissolved and eaten away.
What are the symptoms of impacted wisdom teeth?
Sometimes impacted teeth are asymptomatic — you feel nothing, even though damage is being done to gums and teeth surrounding the wisdom teeth. That's why it's a good idea to have regular checkups even if you are feeling no pain. Other times, impacted teeth can lead to acute inflammation and infection in surrounding gum tissues that is very painful.
Should I proactively have my wisdom teeth removed if they are not giving me any trouble?
Not necessarily but your wisdom teeth need to be evaluated. Generally speaking, however, it's better to remove wisdom teeth early, before they begin to cause dental problems. By the time a wisdom tooth starts to hurt, its neighboring teeth may already be in big trouble. In addition, younger people's wisdom teeth have undeveloped roots that make them easier to remove with fewer complications.
Gum or periodontal disease is a condition in which “biofilms” or dental bacterial plaque sticks to teeth around the gum line in the absence of good oral hygiene. If left untreated, it causes inflammation of the gums and surrounding tissues of the teeth that can result in “pocketing,” gum recession and bone loss that eventually leads to loose teeth, followed by no teeth! And for about 10 to 15% of those having gingivitis or stage 1 periodontal disease, it can get worse by progressing into chronic periodontal disease. However, the good news is that a conservative and simple treatment called root planing combined with good daily oral hygiene may return your gum tissues to health, and even eliminate the need for gum surgery.
Most of the time, root planing is performed with local anesthesia (numbing shots) in the areas requiring treatment. Anesthesia is an important part because you should always feel relaxed and comfortable during treatment. Because inflamed gum tissues may be quite sensitive, these numbing shots enable us to accomplish our goals and thoroughly remove the problematic material from your teeth's roots.
Root planing or deep cleaning is a routine dental procedure usually done in conjunction with scaling, the removal of the more superficial deposits on the tooth surfaces. Root planing involves physically planing (scraping) the root surfaces of the teeth to remove calculus, bacteria and toxins that are ingrained into their surfaces so that the attached gum tissues can heal. It is carried out with manual hand instruments, ultrasonic electronic instruments or a combination of both for your comfort and best results.
When you have your teeth bleached in a dental office, the results almost seem like magic. Let's push aside the magician's cape and see what is really happening in professionally-applied, in-office tooth whitening.
How do teeth become discolored?
A tooth's enamel covering is mostly composed of mineral crystals. At a microscopic level, you can see a framework or matrix of organic (living) matter interspersed between the crystals of enamel creating a very irregular surface capable of retaining stains. Chromagenic (color generating) organic compounds can become part of this organic matrix resulting in tooth staining. They can be bleached without affecting the mineral structure of the tooth's enamel.
As people get older and their teeth wear, the enamel loses its youthful translucency and the underlying layer, called dentin, thickens and becomes more yellow. Such changes to the actual tooth structure are called intrinsic staining. Other causes of intrinsic discoloration are exposure to high levels of fluoride or tetracycline antibiotic administration during childhood, tooth decay, or root canal problems, among others. Discoloration can also be caused by external staining from certain foods, drinks, or tobacco products. Such surface stains are called extrinsic staining.
Behind the Magic
Materials used for tooth bleaching are hydrogen peroxide and carbamide peroxide. Peroxides are commonly used as bleach, and you may have seen them used as hair bleaches, for example. Hydrogen peroxide is a strong oxidizing agent that attacks the organic molecules responsible for tooth discoloration, bleaching them until they lose their color. Carbamide peroxide also contains urea, which is a compound that permits the peroxide to remain in contact with the teeth for longer amounts of time without harming them.
Often called power bleaching, the in-office technique uses a high concentration of peroxide solution (35-45% hydrogen peroxide), placed directly on the teeth in the form of a gel. A heat or light source may enhance the peroxide release. The gel is applied with trays custom fitted to your mouth, and specific barriers are applied to protect sensitive gum tissue from the solution. Results show teeth becoming up to ten shades lighter in about an hour.
In-office bleaching under the supervision of my staff and me is recommended if you have severely stained teeth, and particularly if you are about to have veneers or crowns made. It's a way to rediscover the pearly translucency of your youthful smile.
At some point in every person's life, they will experience bleeding gums or gingivitis, a mild inflammation of the gingiva (gums), which is the first stage of periodontal (gum) disease. For example, when was the last time you were brushing or flossing your teeth and noticed that your gums were bleeding or that when you spit and rinsed there was some blood? When this occurs, it is a sign that you have gum disease, as healthy gum tissues do not bleed. And no, it is highly unlikely that your bleeding is from brushing too hard. You would have to use extreme force to make healthy gum tissues bleed. However, this is exactly how most people discount or ignore this warning sign.
If this sounds like you or another member of your family, here's what you can expect when you see us for treatment. Depending on the severity of your periodontal disease, all of these treatment options may not be necessary.
Behavior change: We will collect a thorough medical history to obtain facts about your oral hygiene, eating and other personal habits such as alcohol and tobacco use to determine their impact on your periodontal disease. Proper brushing and flossing techniques are necessary for everyone, whether you have early or late stage gum disease; however, you must commit to a good daily oral health routine if you want to achieve success and thus keep you mouth and teeth healthy.
Calculus (tartar) removal: Cleaning is not just your responsibility. We'll clean and polish your teeth to remove calculus (tartar), the calcified deposits of bacterial products that become glued to the teeth and roots that you canÃ¢Â€Â™t remove. In fact, routine visits to see us for a thorough cleaning will help ensure that all the unhealthy calculus (tartar) is removed from your teeth.
Evaluation: Usually after three or four weeks, we will want to see you to evaluate your progress and to see the response of your gingival tissues to the treatment thus far. And depending on the severity of your gum disease, we may need another follow-up exam to decide the best maintenance and monitoring regimen necessary to keep your mouth healthy.
Occlusal or Bite Therapy: This treatment, if necessary, usually occurs once your gum tissues have been stabilized and the inflammation and infection have been controlled. It is during this phase that we will address loose teeth or teeth that have shifted or drifted in position.
Surgical Therapy: For more severe cases of gum disease, you may need periodontal plastic surgery to repair and regenerate gum and bone tissue and their attachment to the teeth. It may also be necessary to replace missing teeth with dental implants.

The third molars, called “wisdom teeth” because they usually become visible when a person is 17 to 25 — supposedly the time we achieve wisdom, may have adverse effects on adjacent teeth. Most adults have four wisdom teeth, although some people have more; and some, none at all. The wisest thing to do about wisdom teeth may be to have them removed if they are poorly positioned.
What is an impacted wisdom tooth?
If a wisdom tooth is pushing against gums, other soft tissues, or adjacent teeth at an awkward angle, it is referred to as “impacted.” Usually this occurs when there is not have enough room in the jaws for these last molars to fit next to their adjacent teeth. They can disrupt the gum tissue attachment of their neighboring teeth and the surrounding bone leading to periodontal disease and, ultimately, their loss.
In many cases, impacted teeth are painless, and those who have them have no warning of the problem. Thus it is important to have routine dental exams during the time when the third molars are coming in.
When should wisdom teeth be removed?
It is better to remove wisdom teeth early rather than waiting until periodontal (gum) disease has set in. As individuals age, keeping their wisdom teeth may lead to more serious problems. Periodontal defects tend to get worse in the presence of retained third molars. Furthermore, there is a higher incidence of postoperative symptoms in people over 25.
What are the pros and cons?
Removing impacted third molars can have a negative influence on the periodontal tissues of adjacent second molars. A number of techniques, such as scaling, root planing, and bacterial plaque control, can be used to minimize periodontal problems and promote healthy healing.
Surgical removal of wisdom teeth will involve some mild to moderate post-operative discomfort. Use of aspirin or ibuprofen for a few days after surgery will provide pain relief and control most swelling and symptoms. Antibiotics may be prescribed to ensure infection-free healing. It is important to keep the socket area clean by washing and rinsing with saline or antibacterial rinses. Careful surgery will promote good healing with minimal periodontal consequences to adjacent second molar teeth.
To decide whether your wisdom teeth should be removed, you will need an evaluation to assess the clinical health of the wisdom teeth, the neighboring teeth, and other vital structures. X-ray and digital imaging techniques play an important role in determining the exact position of the wisdom teeth in the jaw. A full assessment and consultation will include all the risks, benefits, likely consequences, and alternative treatment options. This will provide you with the wisdom you need to determine what is best for your wisdom teeth.
