Baby Grinding Teeth

Baby Grinding Teeth 

 

Why does my baby grind his teeth?

Experts don't know for sure what causes teeth grinding, but they point fingers at tension or anxiety, pain (from earaches or teething, for example), and malocclusion (a dental term for when the teeth don't line up just right). Some also suggest that allergies may play a role. And there's some evidence that pinworms are sometimes the culprit. Finally, your toddler may just be getting used to the sensation of having teeth in his mouth.

Your child is a bit more likely to grind his teeth if you do. He's also more likely to grind if he drools or talks in his sleep.

About 38 percent of children grind their teeth, according to a 2005 study published in the Journal of Dentistry for Children. The average age for starting the habit is around 3 1/2 years and the average age for stopping is 6 — though, of course, people of all ages grind their teeth. Almost all teeth grinding happens at night.

Complications of bruxism

Teeth grinding can cause a range of dental problems, which may include:

• Cracked tooth enamel
• Excessive wear and tear on the teeth
• Broken teeth or restorations
• Strain on the joints and soft tissue of the jaw joint (temporo-mandibular joint)
• Temporo-mandibular disorder
• Tooth loss (rarely)
• Enlargement of the jaw muscles (rarely).

A range of causes

Some of the many factors believed to trigger bruxism in susceptible people include:

• Emotional stress, such as anger or anxiety
• Mental concentration
• Physical effort or stress, such as illness, nutritional deficiency or dehydration
• Incorrect tooth alignment, including fillings that are too ‘high’
• Drug misuse (particularly amphetamines)
• Eruption of teeth (babies and children).
