What is bruxism?
  • Bruxism is the medical term for grinding,
    gnashing or clenching your teeth. This condition
    affects both kids and adults.
  • Some people with bruxism unconsciously clench
    their teeth together during the day, often when
    they feel anxious or tense.-called as bruxomania
  • Most kids who have bruxism and some adults with
    the condition grind or gnash their teeth during
    sleep, usually in the early part of the night.
    This is called sleep bruxism.

Why Bruxism should be treated?
  • In most cases, bruxism is mild and may not even
    require treatment. However, it can be frequent
    and violent and can lead to jaw disorders,
    headaches, damaged teeth and other problems.
  • Unfortunately, people with sleep bruxism usually
    aren't aware of the habit, so they aren't
    diagnosed with the condition until complications
    occur. That's why it's important to know the
    signs and symptoms of bruxism and to seek regular
    dental care.

4
Causes
  • Doctors don't completely understand the causes
    of bruxism.
  • In some adults, abnormal alignment of upper and
    lower teeth (malocclusion) may contribute to the
    problem.
  • More often, psychological factors cause bruxism,
    including
  • Anxiety, stress or tension
  • Suppressed anger or frustration
  • Aggressive, competitive or hyperactive
    personality type

5
  • In children, bruxism may be related to growth and
    development. Some researchers think children brux
    because their top and bottom teeth don't fit
    together comfortably.
  • Others believe that children grind their teeth
    because of tension, anger, allergy problems, or
    as a response to pain from an earache or
    teething.

6
  • Bruxism occurs in up to 30 percent of children,
    often around the ages of 5 and 6.
  • It's particularly common in children with
    cerebral palsy or severe mental retardation.
  • But most children outgrow bruxism before they
    get their adult teeth.

7
  • In some cases, bruxism is n't caused by stress or
    dental problems.
  • It can be a complication of another disorder,
    such as Huntington's disease or Parkinson's
    disease.
  • It can also be an uncommon side effect of some
    psychiatric medications including antidepressants.

8
Signs and symptoms
  • Teeth grinding or clenching, which may be loud
    enough to wake your sleep partner
  • Teeth that are worn down, flattened or chipped
  • Worn tooth enamel, exposing the inside of your
    tooth, Increased tooth sensitivity
  • Jaw pain or tightness in your jaw muscles

9
  • Earache because of violent jaw muscle
    contractions, not a problem with your ear
  • Dull morning headache
  • Chronic facial pain
  • Chewed tissue on the inside of your cheek

10
Risk factors
  • Stress- Increased anxiety or stress can lead to
    teeth grinding. So can anger and frustration.
  • Age- Bruxism is common in young children, but
    usually goes away by age 10. In adults, the
    condition is common between the late teen years
    and the 40s. It tends to decrease with older age.
  • Caffeine, nicotine and other drugs. Using
    caffeine, tobacco, cocaine or amphetamines seems
    to increase the risk of bruxism.

11
Screening and diagnosis
  • Physical signs of bruxism-
  • unusual wear and tear on your teeth
  • Broken dental restorations and tooth
    sensitivity.
  • stress level, general dental health, daily
    medications
  • Dentist may also ask your roommate or bed
    partner about sleep habits, especially about any
    unusual grinding sounds heard during the night.

12
  • Checking for tenderness in jaw muscles
  • Obvious dental abnormalities, such as broken or
    missing teeth or poor tooth alignment.
  • Dentist will also inspect teeth, the underlying
    bone and the inside of cheeks for damage caused
    by bruxism. He or she may make a series of X-rays
    of your mouth and jaw.

13
When to seek medical advice
  • Because bruxism often goes unnoticed, be aware of
    its signs and symptoms.
  • If you have worn teeth or pain in your jaw, face
    or ear.
  • Consult your doctor or dentist if your bed
    partner complains that you make a grinding noise
    while you sleep.

14
Complications
  • In most cases, bruxism doesn't cause serious
    complications.
  • But severe bruxism may lead to
  • Damage to your teeth or jaw
  • Tension-type headaches
  • Facial pain
  • Temporomandibular disorders which occur in the
    temporomandibular joints (TMJs), located just in
    front of your ears and felt when opening and
    closing your mouth

15
Treatment
  • In many cases, no treatment is necessary. Many
    kids outgrow bruxism without special treatment,
    and many adults don't brux badly enough to
    require therapy. However, if the problem is
    severe, treatment options include

16
1) Stress management.
  • If you grind your teeth because of stress, you
    may be able to prevent the problem with
    professional counseling that promote relaxation,
    such as exercise and meditation.
  • If your child grinds his or her teeth because of
    tension or fear, it may help to talk about your
    child's fears just before bed or to help your
    child relax with a warm bath or a favorite book

17
2) Dental approaches.
  • Mouth guard or protective dental appliance
    (splint) to prevent damage to your teeth. Dentist
    can make a custom mouth guard to fit mouth.
  • Over-the-counter mouth guards are available and
    they're less expensive than custom guards, but
    they generally don't fit well and can dislodge
    during bruxing.

18
  • If bruxism seems to stem from dental problems,
    dentist may also correct misaligned teeth.
  • In severe cases when tooth wear has led to
    sensitivity or the inability to chew properly
    your dentist may need to use overlays or crowns
    to entirely reshape the chewing surfaces of your
    teeth.

19
3) Behavior therapy.
  • Once you discover that you have bruxism, you may
    be able to change the behavior by practicing
    proper mouth and jaw position.
  • Concentrate on resting your tongue upward with
    your teeth apart and your lips closed. This
    should keep your teeth from grinding and your jaw
    from clenching.

20
4) Biofeedback
  • Therapist applies electrical sensors to different
    parts of your body. These sensors monitor your
    body's physiological responses to stress such
    as teeth grinding and then feed the information
    back to you via auditory and visual cues (beeping
    sound or a flashing light). With this feedback,
    you'll start to associate teeth grinding or
    clenching with stress and learn to change your
    behavior.

21
5)Medications.
  • Medications aren't very effective for treatment
    of bruxism. Doctor may suggest taking a muscle
    relaxant before bedtime.
  • If you develop bruxism as a side effect of an
    antidepressant medication, your doctor may change
    your medication or prescribe another medication
    to counteract your bruxism.
  • Botulinum toxin (Botox) injections may help some
    people with severe bruxism that hasn't responded
    to other treatments.

22
Self-care
  • These self-care steps may prevent or help treat
    bruxism
  • Limit alcohol, tobacco and caffeine.
  • Reduce stress. Keeping your life stresses to a
    minimum
  • Consult your sleep partner- ask him or her to be
    aware of any grinding or clicking sounds that you
    might make while sleeping.
  • Have regular dental examinations.
