Is Having 24 Teeth Normal? The Risks of Premolar Extractions
The Debate Surrounding 24 Teeth
It is not uncommon for orthodontists and dental professionals to suggest that 24 teeth are sufficient for a healthy mouth. However, a recent survey revealed that over 2,000 individuals believe that removing premolar teeth can have significant long-term consequences. One of the most frequently reported issues is the wear down of remaining teeth, which occurs due to the additional burden placed on them. The premolar teeth, being essential for efficient chewing, play a crucial role when removed from the dental arch.
The Concept of Bimaxillary Protrusion
Bimaxillary protrusion is a condition that is often misunderstood. It typically involves the mandible, which may be too far back, rather than the maxilla being overly advanced. Surprisingly, many people who undergo orthodontic treatment for what is termed bimaxillary protrusion find themselves shocked at the aesthetic results. When the upper arch is retracted to meet a lower jaw that was underdeveloped, the resulting facial appearance can appear recessed and unbalanced. This highlights the importance of understanding and accurately diagnosing dental conditions.
Health Risks of Premolar Extractions
The removal of premolar teeth, while sometimes recommended, can have severe health consequences. Research articles have shown that extracting these teeth can cause the airway to narrow, the mandible to recede, and the space for the tongue to decrease. Any of these outcomes, particularly when combined, can lead to lifelong breathing problems such as obstructive sleep apnea. While some might argue that living with a reduced number of teeth is acceptable, the reality is that it significantly impacts overall health and quality of life.
The Impact on Nutrition and Digestion
Having all 24 teeth is not only beneficial for oral health but also for proper nutrition and digestion. A study suggests that individuals born with fewer teeth (hypodontia) have a smaller palate, which can lead to sleep apnea and breathing issues. Reducing the size of the dental arch through premolar extractions can place the body at risk for developing similar health problems. Therefore, any reduction in the number of teeth can compromise an individual's ability to chew and digest food effectively, leading to potential nutritional deficiencies.
The Historical Significance and Professional Misconceptions
Some dental professionals underestimate the importance of all teeth, believing that we are evolving to have smaller jaws and thus fewer teeth. However, these misconceptions can be detrimental. Dentists and orthodontists extracting premolar teeth for aesthetic or orthodontic reasons are merely following a flawed approach. Any dental professional who removes teeth without fully understanding their functions is guilty of malpractice. In the future, these practices will be seen as outdated and unprofessional, akin to quackery.
Identifying and Addressing Sleep Apnea Risks
Studies have found that even minor tooth loss can significantly increase the risk of obstructive sleep apnea (OSA). For example, between five and eight lost teeth were associated with a 25% higher risk of being high-risk for OSA. This underscores the critical role that dental health plays in overall health and the importance of maintaining all teeth to prevent such conditions. Sleep apnea can have severe consequences, including daytime tiredness, cardiovascular issues, and cognitive decline. Therefore, dental professionals should prioritize the preservation of all teeth to support optimal oral and overall health.
Conclusion
Living with 24 teeth is not only perfectly normal but also important for health and well-being. The removal of premolar teeth can have far-reaching and often adverse effects, from reduced chewing efficiency to increased risks of breathing and sleep disorders. Professionals who prioritize aesthetics over patient health may be doing more harm than good. It is crucial for dental practitioners to understand the importance of all teeth and to advocate for holistic approaches to dental care.
