Will My Face Shape Change If My Wisdom Tooth Grows Forward? - Dentistry

Share to:

The second molar has decayed, leaving only the tooth root?


Hello doctor, I would like to ask if the extraction of the lower left second molar, along with the presence of an already partially erupted wisdom tooth, will affect the shape of my face and mouth if the wisdom tooth continues to grow forward.

Wen, 10~19 year old female. Ask Date: 2023/04/27

Hello: A single crooked tooth may not affect the facial shape or mouth shape, but it can impact occlusion and even the temporomandibular joint.
It is advisable to consult an orthodontist to determine if it can be repositioned to replace the second molar!

The growth and positioning of wisdom teeth can indeed influence facial shape and appearance, particularly if they are impacted or growing in an abnormal direction. Wisdom teeth, or third molars, typically emerge in late adolescence or early adulthood, and their growth can exert pressure on adjacent teeth and the jawbone. This pressure can lead to changes in the alignment of your teeth and potentially affect the overall structure of your face.

When a wisdom tooth grows forward, it can push against the second molar and other teeth, which may lead to crowding or shifting of the teeth in the dental arch. This shifting can alter the way your bite aligns, which in turn can affect the muscles and soft tissues of your face. Over time, these changes can contribute to a noticeable alteration in facial shape. For instance, if the teeth are pushed forward, it may create a more pronounced jawline or change the contour of the cheeks, leading to a different facial appearance.

Moreover, if the wisdom tooth is impacted, meaning it is unable to fully emerge due to lack of space or being angled improperly, it can cause inflammation, pain, and infection. These conditions can lead to swelling in the jaw area, which may temporarily change the appearance of your face. Chronic issues related to impacted wisdom teeth can also lead to muscle tension and discomfort, further influencing facial aesthetics.

In your specific case, if the second molar is removed and the wisdom tooth continues to grow forward, it could potentially lead to changes in your facial structure. The extent of these changes will depend on several factors, including the degree of eruption of the wisdom tooth, the existing alignment of your teeth, and how your jaw and facial muscles adapt to these changes.

If you are concerned about the potential impact on your facial shape, it is advisable to consult with an oral surgeon or an orthodontist. They can provide a thorough examination, including X-rays, to assess the positioning of your wisdom teeth and their potential effects on your dental and facial structure. They may recommend extraction of the wisdom teeth if they are likely to cause problems or if they are already causing discomfort.

In summary, while the growth of wisdom teeth can influence facial shape, the degree of change varies from person to person. It is essential to monitor the situation and seek professional advice to ensure that any potential issues are addressed promptly, thereby minimizing any adverse effects on your facial aesthetics.
