Types of Mouth guard

Store-bought mouth guards

They can be purchased from any sports store or drugstore.

  • Sadly, they often do not fit properly.
  • They might be heavy, making breathing and speaking difficult.

Boil to bite mouth guards

  • These mouthguards might fit more comfortably than stock mouthguards.
  • Before being placed, they are made pliable in boiling water so that they will mold to the mouth’s contours.
  • While using them, adhere to the manufacturer’s recommendations on the cover.

What are custom-made mouthguards?

  • Custom-made mouth guards – created by a dentist for every individual.
  • Because they have been customized for fit and comfort, they are more costly than the other kinds.
  • The most effective mouthguard is the one a person’s dentist has built specifically for that person’s mouth.1Types| Researched based study from

  • By reducing background muscle tension, the biting position helps the person’s balance and enables more effective use of their body.

Braces guard

Uses of a Mouth guard

One can use a mouth guard for the following

  • In sports to prevent injuries.
  • Prevents teeth grinding.
  • Prevents snoring.
  • Manages sleep apnea.

In sports to prevent injuries

There is an increased chance of falling or suffering facial injuries in some sports and activities, and mouth guards can help prevent them.

  • Mouthguards protect the lips, tongue, and cheeks from damage caused by teeth during any injury.
  • Prevents bruises and injuries like lacerations and concussions during any trauma.
  • Prevents tooth dislocation or fracture.
  • Prevents lower jaw fractures around the TMJ or jaw line.
  • Prevents a possible neck injury during sport.
  • When players are adequately protected for their head and neck, they feel more confident and forceful.

Prevents teeth grinding

  • Grinding the teeth and clenching, especially at night, are symptoms of bruxism, a movement problem associated with sleep. The symptoms include tooth discomfort, jaw pain, and sore gums.
  • Wearing a custom-made mouthguard while sleeping can assist in keeping the upper and lower teeth apart so they do not harm each other from the force of grinding or clenching and also reduces jaw pain.

Prevents snoring

  • Mouth guards that are specifically made to stop snoring are available, and they function by either holding the tongue and preventing it from slipping back into the throat or moving the lower jaw forward to clear the airway.3Uses| Researched based study from

Manages sleep apnea
