Discover the types of dental mouthguards that exist and what the differences are between the various mouthguards

Problems such as misalignment of teeth, nighttime habits like grinding or clenching teeth (bruxism), or even other conditions such as sleep apnea can have a significant impact on quality of life. In these cases, a common and effective solution is the use of maxillary interposition devices, commonly known as dental mouthguards. But in which situations is a dental mouthguard recommended? And what types are available? Find the answers to all your questions here.

In what situations should I use a dental mouthguard?

Dental mouthguards are removable devices, crafted according to each patient's oral characteristics, that serve several therapeutic and protective functions. Some of the main reasons for using a dental mouthguard include:

Bruxism (grinding or clenching teeth)

Bruxism, which can occur both during the day and at night, is a condition where a person involuntarily grinds or clenches their teeth. This behavior causes dental wear, headaches, tooth sensitivity, and muscle pain in the facial and/or neck area. In these cases, the dental mouthguard acts as a barrier placed between the teeth, preventing wear and protecting the dental structure. In the case of nighttime bruxism, the mouthguard should be put on before going to sleep.

Jaw joint pain and disorders (TMJ)

The temporomandibular joint (TMJ) connects the jawbone to the temporal bone (skull), involving the masticatory muscles and all associated structures. Problems in this joint can cause pain, difficulty chewing, and opening or closing the mouth, as well as clicking sounds when performing such movements. In these situations, mouthguards are used to relieve the pressure exerted on the joint, redistributing the bite force and helping to relax the facial muscles.

Occlusion problems (incorrect bite)

Some mouthguards are indicated for patients with misaligned teeth. By using a dental mouthguard, the bite can be adjusted over time, preventing uneven wear of teeth and problems in the joint.

Sleep apnea

Some mouthguards, called mandibular advancement devices, are also recommended for patients with mild to moderate sleep apnea. They keep the jaw in a more advanced position during sleep, preventing airway obstruction and improving breathing.

Sports protection

Athletes participating in contact sports, such as rugby or boxing, for example, should also use dental mouthguards to protect their teeth against impacts that could cause fractures or dental injuries.

Types of dental mouthguards

 There are several types of mouthguards, each intended for different cases and for treating different conditions. The main types of dental mouthguards are:

  1. Bruxism mouthguard: One of the most common types of mouthguards, bruxism mouthguards are used to protect the teeth of those suffering from this condition. Generally made from acrylic or silicone material, these mouthguards create a protective layer between the upper and lower teeth, preventing direct contact and grinding of the teeth.

  2. Mandibular repositioning mouthguard: For people with temporomandibular joint (TMJ) problems, the mandibular repositioning mouthguard places the jaw in the correct position, relieving pressure and helping to reduce symptoms such as pain and clicking.

  3. Sports mouthguard: Also known as a dental protector, this type of mouthguard is designed to minimize the impact of blows or falls, preventing fractures and other damage to the teeth during contact sports.

  4. In addition to these, there is also a dental mouthguard for performing teeth whitening, also molded according to each patient's dental arch. These mouthguards are used to apply the whitening gel and should be used for the period indicated by the dentist or

Benefits of dental mouthguards

Dental mouthguards offer a range of benefits that go beyond tooth protection. They are versatile devices used to treat a variety of conditions that affect not just oral health but overall well-being. For this reason, the benefits of dental mouthguards are: 

  • Protection of teeth against dental wear

  • Relief from muscle and joint pain (from TMJ)

  • Improvement in sleep quality

  • Bite correction (resolution of occlusion problems)

  • Reduction of headaches and neck pain

  • Improvement in breathing

  • Prevention of dental fractures

Using a dental mouthguard can bring numerous health benefits, from protecting the teeth to improving quality of life, helping to address conditions such as bruxism, temporomandibular joint (TMJ) problems, and even sleep apnea.

To ensure that the dental mouthguard and treatment are effective, it is essential that it is tailored to the specific needs and characteristics of each patient, with appropriate follow-up from a specialist dentist.
