Wisdom Teeth

Wisdom teeth, or third molars, are removed only if they are deemed potentially problematic. There are several reasons a wisdom tooth might be labeled as problematic. Factors that determine whether or not wisdom teeth must be removed include jaw size, crowding, proper occlusion, and impaction. Often, radiographs taken at regular dental cleaning appointments will show when wisdom teeth extraction is recommended.

Introduction to Third Molars

Narrator: Wisdom teeth, or third molars, are the last teeth to develop and enter your mouth[cite: 164]. If wisdom teeth come into the mouth in a proper position and meet certain conditions, it's generally accepted that you can keep them[cite: 165]. However, they are still prone to disease, even if you experience no pain and have no symptoms[cite: 166]. This is why the American Association of Oral and Maxillofacial Surgeons strongly recommends that third molars be evaluated annually from the time a patient is a young adult[cite: 167].

The Risks of Impacted Wisdom Teeth

Narrator: Studies have shown that about nine out of ten people have at least one wisdom tooth that can't break through the gums in an upright, functional position[cite: 168]. As we say, it becomes impacted[cite: 169]. If left alone, an impacted tooth can become infected or damage neighboring teeth[cite: 169]. That can lead to gum disease and even the formation of cysts or tumors[cite: 170]. By the time you feel pain or notice that something is wrong, it may be too late to prevent the problem[cite: 171].

Narrator: The tooth does have to be removed[cite: 172]. It's better to do it when you are young and the roots haven't fully formed[cite: 172]. There's less chance that the roots of the teeth will damage nearby nerves or other structures[cite: 173]. Oral and facial surgeons are the recognized specialists in the management of third molar teeth[cite: 174]. Usually, the surgical care can be provided in an oral and facial surgeon's office[cite: 175]. The surgeon's skill and knowledge of anesthesia care assure you of a safe and comfortable surgical experience[cite: 176].

Long-Term Wisdom Teeth Management

Narrator: If, after consulting with your family dentist and oral surgeon, you decide to keep your wisdom teeth, they do require proper management[cite: 177, 178]. That includes professional cleaning on a regular basis, annual checkups, and periodic X-rays to monitor for changes[cite: 178]. This will ensure the best possible oral health as it relates to your wisdom teeth[cite: 179].

Patient Perspectives: Unexpected Clinical Diagnoses

Roger: My name's Roger, and my story is I went to the dentist because I was having a lot of pain in my back teeth, and I had wisdom teeth impacted[cite: 181]. It seemed to him that there was an unusual amount of bone loss[cite: 182]. He recommended that I see an oral surgeon, and he agreed that it was unusual for someone in their 30s to have this amount of bone loss[cite: 187]. And he suggested strongly that I take an HIV test[cite: 188]. And so I did, and it turns out I was HIV positive, and the result was showing up in bone loss in my mouth—severe bone loss[cite: 189]. There was a lot of sadness around losing my teeth and feeling HIV, knowing that I was HIV positive[cite: 195]. And then to have such a wonderful experience with this oral surgeon, not only just the work that he did on my mouth, but the understanding that I could be healthy again—that he was encouraging me[cite: 196]. In my case, it was really about saving my life[cite: 200].

Mark: Several years ago, I was having some pain with my wisdom tooth and went to the dentist to have them evaluate and see what was going on[cite: 183]. Along with that examination, they determined that I had a tooth that had never descended and was actually fully grown and impacted in my nasal cavity[cite: 184]. After my general dentist referred me to this maxillofacial surgeon to talk about possibly extracting this tooth, I had never even heard of a maxillofacial surgeon before this[cite: 190]. So I was quite intimidated[cite: 190]. He seemed pretty confident that he knew what he was talking about, and that put me at ease[cite: 191].

Phyllis: I had a swelling on the side of my face, and I went to the dentist, and he immediately walked me down the hall to an oral surgeon[cite: 185]. It had wrapped itself around the nerves to my face, and it was larger than a golf ball[cite: 186]. The oral surgeon had equipment that the dentist did not have[cite: 192]. He told me what had caused the cyst—that it was caused by the impacted wisdom tooth[cite: 193]. He told me the severity of the problem, so he recommended that we do surgery immediately, which we did within, I believe it was, a few days[cite: 194]. I hate to think what would have happened if I'd never gone to the oral surgeon that day[cite: 197]. Basically, he saved my face[cite: 197].

Conclusion

Mark: I think the surgery went well[cite: 198]. I have a smile that I'm proud of[cite: 199]. Thank you, thank you so much for helping me understand about my own personal health and self-care[cite: 201].

An impacted tooth is one that is blocked from erupting. Impacted wisdom teeth that are blocked from coming in properly:

  • May instead come in at an angle, pushing against the molars and causing overcrowding.
  • May not erupt fully, remaining instead either partially or fully below the gum line.
  • May cause bacteria to become trapped beneath the gum and lead to infection and gum disease.

Wisdom teeth extraction is generally an effective means of preventing crowding of the teeth, impaction of wisdom teeth, red, swollen, or painful gums caused by a partially erupted wisdom tooth, and gum disease and tooth decay.

Depending on the complexity of the extraction, the doctor will use local anesthesia, sedation, or general anesthesia to increase patient comfort during and after the procedure. Generally, the procedure can be performed in the doctor’s office.
