The Temporomandibular Joint Disorder

The temporomandibular joint disorder or TMJD affects our temporomandibular joints, ligaments, and muscle tissues in our jaws. You may feel the sensations and symptoms are pain, tenderness, and difficulty moving your jaw, especially when chewing.

Types of Mouth Guards

Mouthguards come in three different types. Although they have the same purpose of protecting the teeth from TMJD or bruxism and sports injuries, it’s imperative to learn their differences. So, here are the three types of mouth guards that you can try, depending on your condition, or as recommended by your dentist:

  • The Stock Dental Mouth Guard: This type of mouthguard is the most common. They are available in most sporting goods stores and are quite inexpensive. Despite their advantages, the only downside of wearing a stock dental mouth guard is the fit. They are made with a standard shape and size that usually doesn’t fit right. You can still wear them if you’re looking for quick and temporary relief from TMJD or bruxism. 
  • The Boil and Bite Mouth Guards: The advantage of the boil and bite mouthguard over the stock type is that it can be heated via warm water and reshaped with tongue pressure. They are also widely available and can be purchased at most sporting goods centres. The thermoplastic materials that it is made of makes it malleable.
  • The Custom Fitted Mouth Guards: This type of mouthguard is the best among all the other types because they are made to fit perfectly as per your dentist’s instructions. The process takes a few days to complete, but the wait and expenses are all worth it. They provide the maximum protection to your teeth because of their perfect fit. It can be more expensive than the first two types we mentioned above because they are individually created. 

You can use any of these mouth guards if you have TMJD or bruxism. However, we highly recommend the custom fitted night guard above all. They optimise the efficiency of the treatment for TMJD and bruxism, which ultimately leads to better sleeping patterns.

Mouth Guard Care

The importance of using the right type of dental night guard can save you from spending too much money on complicated cases. They can provide the relief you need from a restless night’s sleep, affecting your waking hours. They may be uncomfortable at first, but after a few nights, we’re sure that you’ll get used to them. We also advise regular visits to a specialist to check the status of your TMJD or bruxism. They can determine if the dental night guard is effective or not. Please follow your dentist’s instructions at all times.
