Jaw Tremors After Bite Splint Use: the Causes and Solutions - Dentistry

Jaw tremors after the use of a bite splint can be concerning and uncomfortable, especially when they persist for an extended period. It’s important to understand the potential causes and solutions for this issue.

When you wear a bite splint, it is designed to help alleviate symptoms associated with temporomandibular joint (TMJ) disorders and bruxism (teeth grinding). The splint works by repositioning the jaw and providing a cushion between the upper and lower teeth, which can help reduce strain on the jaw muscles and joints. However, as you have experienced, the adjustment to a new bite position can sometimes lead to unexpected side effects, such as jaw tremors.

The tremors you are experiencing may be attributed to several factors:
1. Muscle Adaptation: As your jaw muscles adjust to the new position created by the bite splint, they may initially react with tremors or spasms. This is similar to how other muscles in the body may tremble when they are being used in a new way or after a period of disuse. While muscle adaptation is a normal process, it typically should not last for more than a few weeks. If the tremors persist beyond this period, it may indicate that the muscles are under undue stress or that the splint is not fitting properly.

2. Overactive Muscles: The muscles responsible for jaw movement may become overactive or hypertonic due to the new bite position. This can lead to involuntary movements or tremors. If the splint is not providing adequate support or if it is causing misalignment, the muscles may be working harder than necessary, leading to fatigue and tremors.

3. Nerve Sensitivity: In some cases, the adjustment of the jaw can affect the surrounding nerves, leading to increased sensitivity or involuntary muscle contractions. This can result in tremors or spasms in the jaw area.

4. Psychological Factors: Anxiety or stress related to the discomfort of the splint or the underlying TMJ issues can also manifest as muscle tension and tremors. The mind-body connection is powerful, and psychological stress can exacerbate physical symptoms.

Given that you have already consulted with a neurologist and have not found any neurological issues, it may be beneficial to revisit your dentist or the specialist who provided the bite splint. Here are some potential solutions to consider:
- Re-evaluation of the Bite Splint: It may be necessary to adjust the bite splint further to ensure it is fitting correctly and providing the appropriate support. Sometimes, a slight modification can make a significant difference in comfort and muscle response.

- Physical Therapy: Engaging in physical therapy focused on the jaw and neck can help strengthen the muscles and improve coordination. A physical therapist can provide exercises to help relax the jaw muscles and reduce tremors.

- Relaxation Techniques: Incorporating relaxation techniques such as deep breathing, meditation, or gentle stretching can help alleviate muscle tension and reduce anxiety, which may contribute to tremors.

- Medication: In some cases, muscle relaxants or other medications may be prescribed to help manage muscle spasms and tremors. Discuss this option with your healthcare provider if the tremors are significantly impacting your quality of life.

- Follow-Up Appointments: Regular follow-ups with your dentist or TMJ specialist are essential to monitor your progress and make any necessary adjustments to your treatment plan.

In conclusion, while it is not uncommon to experience some discomfort or muscle adjustment when using a bite splint, persistent jaw tremors warrant further investigation and intervention. By working closely with your healthcare providers and exploring various treatment options, you can find a solution that alleviates your symptoms and improves your overall well-being.
