Dental Night Guards: Are the Side Effects Worth Considering?

Introduction

Dental night guards are widely recommended for individuals suffering from various dental issues such as teeth grinding (bruxism) and temporomandibular joint disorder (TMD). These custom-fit oral appliances provide a protective barrier between the upper and lower teeth, preventing damage caused by grinding or clenching. While dental night guards offer numerous benefits, it is essential to understand the potential side effects associated with their use. In this article, we will explore the side effects of dental night guards and discuss the importance of considering them before starting the treatment.

1. Discomfort and Tenderness

One of the most commonly reported side effects of dental night guards is discomfort and tenderness. Wearing a foreign object in your mouth during sleep can initially cause discomfort, making it challenging to adjust. Some individuals may experience tenderness and soreness in their jaw muscles, teeth, or gums as they get used to the night guard. However, these symptoms typically subside with time as the oral tissues adapt to the appliance. In most cases, the discomfort can be managed by wearing the night guard for shorter durations initially and gradually increasing the time.

2. Salivation and Speech Changes

Wearing a dental night guard can also cause changes in saliva production and speech patterns. Many people naturally produce more saliva when wearing a night guard, leading to increased saliva pooling or drooling during sleep. Additionally, some individuals may experience difficulty speaking clearly due to the presence of the oral appliance. These issues are generally temporary and tend to diminish as the mouth adjusts to the night guard. Practicing speaking with the appliance in during the day can help speed up the adaptation process.

3. Misaligned Bite

In some cases, the prolonged use of a dental night guard can contribute to a misaligned bite. The constant presence of the appliance may cause the upper and lower teeth to shift slightly, resulting in a changed bite alignment. While this side effect is not very common, it can be problematic for individuals with pre-existing bite issues or orthodontic treatments. Regular dental check-ups and adjustments can help prevent any significant changes in bite alignment caused by the night guard.

4. Ulcers and Tissue Irritation

If a night guard is poorly fitted or not properly adjusted, it can cause ulcers and irritation in the oral tissues. Rough or sharp areas on the night guard's surface can rub against the cheeks, gums, or tongue, leading to the formation of painful ulcers or sore spots. It is crucial to ensure that the night guard is custom-made to fit your mouth precisely and that any rough edges are adequately smoothed by a dental professional. Regular inspections of the night guard for signs of wear or damage are necessary to prevent tissue irritation.

5. Temporomandibular Joint Discomfort

While dental night guards are often recommended for individuals with temporomandibular joint disorder (TMD), they can, in some cases, exacerbate the symptoms. The presence of the appliance may put additional pressure on the jaw joint, leading to discomfort or worsening of TMD symptoms such as jaw pain, headaches, and clicking sounds. If you have a history of TMD, it is vital to consult with your dentist or specialist to determine if a night guard is appropriate for your specific situation.

Conclusion

Dental night guards offer effective protection against teeth grinding and provide relief to individuals suffering from various dental conditions. However, it is crucial to be aware of the potential side effects that may arise during the adaptation period. Discomfort, tenderness, changes in saliva production and speech, misaligned bite, ulcers, tissue irritation, and temporomandibular joint discomfort are some of the possible side effects associated with night guard use. By understanding and addressing these potential issues, individuals can make an informed decision regarding the use of dental night guards and work closely with their dental professionals to ensure optimal treatment outcomes.
