What does a Night guard do?

  • Reduces the strain on jaw muscles
  • Reduces discomfort
  • Reduces Temporomandibular joint issues (TMJ)
  • Relieves headaches

It is an oral device called an occlusal splint intended to guard the teeth and jaws as you sleep. It is primarily used to treat the adverse effects of bruxism, which is the habit of clenching or grinding the teeth, usually subconsciously, while sleeping.9Benefits| Researched based study from

Safeguards teeth

  • Between the upper and lower teeth, it serves as a cushion barrier.
  • When you clench or grind your teeth while you sleep, it distributes and absorbs the pressures, preventing the teeth from coming into direct contact.
  • This result lowers the possibility of tooth injuries, such as chipping, cracking, or enamel degradation.9Benefits| Researched based study from

Minimizes muscle tension

  • The extreme strain that bruxism places on the jaw muscles can cause pain and discomfort in the jaw.
  • Allowing a tiny space between the upper and lower jaws helps reduce this stress.
  • It lessens tension on the jaw muscles and lowers jaw discomfort and soreness by promoting a more relaxed jaw posture.

Minimizes TMJ-related problems

  • Bruxism can impact the temporomandibular joint, which joins the jaw to the skull.
  • This joint can become overworked by excessive clenching or grinding, which can cause conditions that cause clicking, popping, or restricted jaw mobility.
  • The night guard aids in dispersing forces and lessening joint stress, potentially lowering TMD-related problems.9Benefits| Researched based study from

Alleviates headaches

  • Bruxism can aggravate migraines or tension headaches.
  • It may help lower the severity and frequency of these headaches by safeguarding a barrier between the teeth and absorbing the pressures applied.

Safeguards dental work

  • Grinding or clenching can put too much pressure on dental restorations like crowns, bridges, or veneers, which can cause damage or dislodgment.
  • The guard serves as a shield, preserving and extending the life of your dental work.

Improving sleep quality

  • They provide a sound barrier, muffling the noise produced during grinding and allowing for better sleep quality.9Benefits| Researched based study from
