Grinding & Clenching - Face Focused Orthodontics

Grinding vs. Clenching:

Grinding (Bruxism):

Grinding, also known as bruxism, is the involuntary movement of the teeth against each other, often accompanied by a side-to-side motion. It typically occurs during sleep but also during the day.

Clenching:

Clenching involves the constant, forceful pressing of the upper and lower teeth together without the lateral movement seen in grinding. It can occur both during the day and at night.

How Misaligned Teeth, Jaw Position, and Poor Breathing can cause Grinding and Clenching & It’s effect:

Uneven Bite Pressure: When the teeth do not fit together properly (known as malocclusion), it creates an imbalance in the way the upper and lower teeth meet. This uneven bite can cause the jaw muscles to overcompensate, leading to grinding and clenching as the body tries to “correct” the alignment during rest or sleep.
Jaw Instability: An imbalanced bite can create instability in the jaw joint (temporomandibular joint or TMJ), making it more susceptible to involuntary movements like grinding and clenching.
Overactive Jaw Muscles: Misalignments require the jaw muscles to exert more effort to achieve closure and movement, resulting in chronic muscle tension and fatigue.
Stress Response: The additional strain from an improper bite can trigger a stress response in the body, exacerbating habits like clenching and grinding as subconscious coping mechanisms.
Shift in Jaw Position: To find a more comfortable position, the jaw may shift forward, backward, or sideways, disrupting the natural alignment and promoting grinding and clenching behaviors.
Altered Tongue Posture: Misalignments can affect how the tongue rests and moves, influencing jaw positioning and muscle activity.
Interrupted Breathing: Jaw misalignments can contribute to airway obstructions, leading to sleep disturbances such as sleep apnea. These interruptions can trigger grinding and clenching as the body reacts to regain proper breathing patterns.
Poor Sleep Quality: Disrupted sleep increases overall stress and fatigue, known triggers for nocturnal bruxism.

What are some of the ways we can address these issues?

Orthodontic Treatment:

Braces and Aligners: Correcting dental misalignments with braces or clear aligners can create a balanced bite, reducing the need for compensatory grinding and clenching.
Bite Correction Appliances: Devices such as splints or night guards can help redistribute bite forces and protect teeth from excessive wear.

Misaligned teeth and improper jaw positions play a significant role in the development of grinding and clenching behaviors. By addressing these structural issues through orthodontic and medical interventions, individuals can alleviate the symptoms of bruxism, protect their dental health, and improve their overall quality of life. If you suspect that dental misalignments are contributing to your grinding or clenching habits, schedule a consultation with us and learn more!

Jaw Realignment Procedures:

Orthognathic Surgery: In severe cases, surgical intervention may be necessary to realign the jaws, providing a stable foundation for proper bite function.
Physical Therapy: Exercises and therapies aimed at strengthening and relaxing jaw muscles can alleviate tension and improve jaw positioning.

Behavioral Modifications:

Stress Management: Techniques such as mindfulness, meditation, and biofeedback can help reduce overall stress levels, decreasing the tendency to grind and clench.
Habit Awareness: Becoming aware of clenching habits during the day and consciously relaxing the jaw can prevent the development of more severe grinding behaviors.
