Orthodontics is a branch of dentistry concerned with diagnosing, preventing, and treating dental and facial irregularities, primarily through braces, aligners, and other corrective devices. Wisdom teeth, or third molars, are the last molars that typically erupt in late adolescence or early adulthood. Their development can significantly impact orthodontic treatment, leading to problems such as crowding, misalignment, and pain.

This article reviews the multifaceted relationship between wisdom teeth and orthodontics, including their impact on tooth alignment, treatment planning, and how to manage complications.

The Role of Orthodontics

Orthodontic treatment is designed to straighten crooked teeth, enhance the bite’s function, and increase dental beauty. The most prevalent orthodontic treatments are:

  • Braces: ceramic or metal brackets cemented to the teeth, connected by wires that exert pressure on teeth to move them over time.
  • Clear Aligners: Aligners are removable, individually made trays (similar to Invisalign) that move teeth slowly into the new position.
  • Retainers: Devices worn following braces or aligners to hold teeth in their aligned position and inhibit relapse.
  • Palatal Expanders: Devices that widen the upper jaw to correct crowding or crossbites.

Orthodontics Oxley carefully plans treatments based on individual dental structures, growth patterns, and potential obstacles—including the emergence of wisdom teeth.

Wisdom Teeth: Function and Potential Problems

Wisdom teeth are the last set of molars, usually erupting between 17 and 25. While they served a functional purpose for our ancestors, who had more enormous jaws and a diet that required extensive chewing, modern humans often lack the jaw space to accommodate these additional teeth.

Common Issues with Wisdom Teeth:

  1. Impaction: Wisdom teeth may become trapped beneath the gums or jawbone, leading to pain, swelling, and infection.
  2. Crowding: If space is insufficient, wisdom teeth can push against adjacent teeth, disrupting alignment achieved through orthodontic treatment.
  3. Partial Eruption: A partially erupted wisdom tooth can create a pocket where bacteria accumulate, increasing the risk of gum disease and cavities.
  4. Cysts and Tumours: In rare cases, impacted wisdom teeth can develop cysts or benign tumours, damaging surrounding structures.

Given these potential issues, orthodontists must evaluate the impact of wisdom teeth when planning and maintaining orthodontic treatments.

Wisdom Teeth and Orthodontic Treatment

1. Should Wisdom Teeth Be Removed Before Orthodontic Treatment?

Not all patients require wisdom tooth extraction before or during orthodontic treatment. Orthodontists assess several factors before recommending removal:

  • Available Space: If a patient has adequate jaw space, wisdom teeth may not pose an issue.
  • Angle of Eruption: The direction in which wisdom teeth grow determines their potential impact on alignment.
  • Crowding Risk: Extraction may be advised if wisdom teeth are likely to cause crowding.
  • Current Dental Health: Infections, cavities, or gum issues related to wisdom teeth might necessitate removal before orthodontic treatment.

2. Can Wisdom Teeth Affect Braces and Alignment?

A common concern among patients is whether wisdom teeth can undo the progress made by braces. While wisdom teeth exert pressure as they erupt, they do not always cause significant shifting. Instead, general tooth movement over time (relapse) is a normal post-orthodontic phenomenon that can be prevented with consistent retainer use.

3. What If Wisdom Teeth Erupt After Braces?

Orthodontists tend to monitor their impact in cases of the appearance of wisdom teeth after treatment with braces or aligners. Wisdom teeth may not impact alignment at all in some instances. Removal may be recommended if problems like pain, impaction, or movement occur.

4. Can Wisdom Teeth Be Removed While Wearing Braces?

Yes, wisdom teeth can be extracted while undergoing orthodontic treatment. However, timing is crucial.

  • Early Removal: Early extraction can prevent complications if wisdom teeth are impacted and causing issues.
  • Mid-Treatment Removal: Orthodontists may sometimes recommend extraction during braces treatment to facilitate smoother alignment.
  • Post-Treatment Monitoring: If wisdom teeth are not causing immediate problems, orthodontists may wait until after treatment to determine if removal is necessary.

The Role of Retainers After Orthodontic Treatment

Retainers play a critical role in maintaining alignment after braces or aligners. Since all teeth, not just wisdom teeth, naturally shift over time, retainers help keep teeth in their corrected positions.

Types of retainers include:

  • Fixed Retainers: Bonded wires attached to the back of teeth, offering long-term stability.
  • Removable Retainers: Clear plastic or acrylic retainers should be worn consistently, especially after orthodontic treatment.

Regardless of wisdom tooth status, orthodontists emphasise the importance of retainers to prevent relapse.

Wisdom Teeth Extraction: The Procedure and Recovery

If extraction is necessary, the procedure is typically performed by a dentist or oral surgeon. Here’s what to expect:

The Extraction Process:

  • Evaluation: X-rays show the position and condition of the wisdom teeth.
  • Anesthesia: Local sedation or general anesthesia is administered based on complexity.
  • Extraction: The dentist or surgeon extracts the tooth, occasionally in pieces.
  • Closure: Stitches may be placed if necessary.

Post-Extraction Recovery:

  • Swelling and Pain: Common in the first few days; managed with pain relievers and ice packs.
  • Dietary Restrictions: Soft foods and liquids are recommended for a few days.
  • Oral Hygiene: Gentle rinsing with salt water helps prevent infection.
  • Activity Limitations: Strenuous activity should be avoided for a few days.

Full recovery typically takes 1-2 weeks, though healing may vary based on individual factors.

Myths and Misconceptions About Wisdom Teeth and Orthodontics

Myth 1: Wisdom Teeth Always Cause Crowding

While wisdom teeth can contribute to pressure, they are not the sole cause of dental shifting. Retainers are the primary factor in maintaining alignment.

Myth 2: Wisdom Teeth Must Be Removed Before Braces

Removal is only necessary if wisdom teeth directly threaten orthodontic treatment.

Myth 3: Braces Are Ineffective If Wisdom Teeth Erupt

Braces can successfully align teeth regardless of wisdom teeth status, though monitoring is essential.

Conclusion

Orthodontics and wisdom teeth go hand in hand, potentially influencing alignment, treatment design, and stability post-treatment. While not always extracted, orthodontists must observe wisdom teeth’ eruption and orientation to prevent future issues. Retainers are also crucial in preventing relapse; early removal can sometimes be necessary. Patients can provide informed consent regarding their oral well-being by being aware of orthodontics’ interaction with wisdom teeth, ensuring long-term satisfaction and comfort.

If you are concerned about orthodontics and wisdom teeth, the best way to determine what you should do is to consult an experienced orthodontist or oral surgeon.
