What is it

What is a stress breaker mouth guard?

Updated May 12, 2026

A stress breaker mouth guard is a rigid plastic or acrylic dental protection custom-made for the patient. It is placed over the upper or lower teeth to protect them from wear caused by bruxism (the involuntary action of grinding or clenching teeth). The mouth guard acts as a barrier between both dental arches, absorbing the pressure exerted during bruxism.

Excessively clenching or grinding the teeth can cause real damage to tooth enamel, potentially causing a tooth to crack, chip or loosen. In addition to tooth fractures, it can cause a wide variety of other problems, such as headaches, jaw pain and muscle tension. During bruxism, there is strong contact between the biting surfaces of the upper and lower teeth.

There are numerous potentially effective approaches to treating bruxism, and a multi-pronged offensive should definitely be used to combat this disorder. One of the most common elements of a teeth-grinding treatment plan is the use of a mouthguard or dental splint for sleeping, as most teeth grinding tends to occur at night. Among the various treatments available for bruxism, the most common are occlusal splints or relief splints.

General considerations on stress breaker mouth guards

There are a number of general considerations regarding stress breaker mouth guards:

  • The mouthguard is normally used for the upper or lower jaw only.
  • Ideally, the dental relief splint should be custom-fitted to the individual's mouth. One size does not fit all. Dental splints are fitted with considerably more precision than sports mouth guards, and the dentist can achieve a perfect fit that will provide comfort and durability.
  • If you grind your teeth during the day and at night, you may need to opt for two mouth guards. Otherwise, you could wear one down too quickly or lose it during the day and have nothing to wear at night.

Se me había roto mi férula de descarga y fui para que me hicieran una nueva. Estoy satisfecho con la calidad y porque se me ha corregido un poco de mordida cruzada que tenía. Instalaciones modernas y bien ubicadas, y trato profesional y amable.
