Crooked teeth are a common concern for both children and adults, often affecting not only the appearance of a smile but also overall oral health. While many people assume crooked teeth are simply a matter of luck, the reality is that several factors can contribute to dental misalignment. At Murphy Orthodontics, we believe that understanding the causes of crooked teeth can help patients make informed decisions about treatment options, such as Invisalign® and traditional braces, to achieve a straighter, healthier smile.
Genetics and Family History
One of the most significant causes of crooked teeth is genetics. If your parents or close relatives have crowded, misaligned, or unevenly spaced teeth, there is a good chance you may inherit similar dental traits. Genetic factors can also influence jaw size and shape, which plays a major role in how teeth develop and align. For example, if your jaw is smaller than average, your teeth may not have enough room to grow in properly, leading to crowding and overlapping.
Childhood Habits
Certain childhood habits can contribute to crooked teeth over time. Thumb sucking, prolonged pacifier use, or tongue thrusting (when the tongue pushes against the teeth while swallowing) can place pressure on developing teeth and jaws. These habits often cause the front teeth to shift forward or create gaps, resulting in misalignment as children grow. While some children naturally outgrow these habits, others may need early orthodontic intervention to help prevent long-term effects.
Early Loss of Baby Teeth
Baby teeth act as natural placeholders for permanent teeth. If they are lost too early due to decay, trauma, or other issues, surrounding teeth may begin to drift into the open space. This can cause crowding when permanent teeth eventually erupt, leading to crookedness or bite problems. On the other hand, if baby teeth are retained for too long, they may block permanent teeth from coming in properly, creating further alignment challenges.
Jaw Size and Alignment Issues
The size and alignment of the jaw can directly impact how teeth fit together. In modern times, changes in diet—particularly a shift toward softer, processed foods—are believed to have reduced the amount of chewing force needed, leading to smaller jaw development in some people. A smaller jaw may not provide sufficient space for teeth, increasing the likelihood of crowding or misalignment. Additionally, jaw misalignments such as overbites, underbites, or crossbites can cause teeth to shift unevenly.
Dental Trauma and Injuries
Accidents or injuries to the mouth can also result in crooked teeth. A blow to the face or jaw can dislodge teeth, alter their position, or damage the supporting bone structure. Even after healing, the teeth may shift out of alignment over time, leading to crookedness that may require orthodontic correction.
Poor Oral Habits and Health
Certain lifestyle habits and oral health issues may contribute to misalignment. For example, consistent mouth breathing (often due to allergies or nasal obstruction) can affect jaw and dental development in children, sometimes leading to crooked teeth. Gum disease in adults can cause teeth to loosen and shift, further contributing to crookedness.
Why Straight Teeth Matter
While crooked teeth may seem like only a cosmetic concern, they can also impact oral health and daily comfort. Misaligned teeth are harder to clean effectively, which increases the risk of plaque buildup, cavities, and gum disease. Crooked teeth may place uneven pressure on the bite, leading to jaw discomfort or even temporomandibular joint (TMJ) issues. By seeking treatment, patients can not only improve the look of their smile but also protect their long-term oral health.
Treatment Options for Crooked Teeth
At Murphy Orthodontics, our doctors offer advanced treatment options to correct crooked teeth and create healthier, more beautiful smiles.
- Braces: Traditional braces use metal brackets and wires to gradually shift teeth into alignment. They can be highly effective at treating even the most complex cases of crowding or bite problems. Today’s braces are smaller, more comfortable, and more efficient than ever before.
- Invisalign®: Invisalign® clear aligners are a popular alternative for patients who want a more discreet treatment option. These removable aligners are custom-made to fit comfortably over your teeth, gently guiding them into place. Since they are nearly invisible, Invisalign® may be especially appealing for teens and adults who prefer a more subtle approach.
The choice between braces and Invisalign® generally depends on individual needs, lifestyle, and treatment goals. During your consultation, your doctor will recommend the option that works best for you.
When to Seek Orthodontic Care
Orthodontic treatment is typically most effective when started at the right time. The American Association of Orthodontists recommends that children have their first orthodontic evaluation by age seven. However, it’s never too late to pursue treatment. Many adults choose braces or Invisalign® to correct crooked teeth and achieve the smile they’ve always wanted.
