Causes Of Bruxism (Teeth Grinding)

You may grind your teeth due to stress and anxiety, sleep disorders, intestinal parasites, certain medications, or improper alignment of your teeth. Lifestyle factors like smoking, the use of recreational drugs, or the excessive consumption of alcohol or caffeine can also lead to teeth grinding. Personality types that have a markedly negative emotional response to any loss, frustration, or threat and are unusually self-critical or sensitive to criticism may be more prone to this.

Do you wake you with aching teeth or stiffness in your temples and face? Ever considered the possibility that you might be grinding your teeth in your sleep? Teeth grinding, medically known as bruxism, usually happens when you’re asleep though, sometimes, people do it when they’re awake too. It’s estimated that around 5% of the population suffers from this condition.1 Bruxism can not only be painful but also strain your jaw joint, wear down your teeth, or cause tooth enamel to chip. So, when does this happen?

Why You Grind Your Teeth

1. Anxiety And Stress

Being anxious or stressed can make you grind your teeth or clench your jaw. According to research, about 70% of cases of teeth grinding that occurs during sleep is caused by anxiety and stress, which has a subconscious effect while you’re asleep.

What to do: Relaxation therapies like breathing techniques and meditation may help you deal with anxiety and stress. Cognitive behavioral therapy, a talk therapy that focusses on identifying unhelpful thoughts and behavioral patterns and changing them, can also be useful.3

2. Personality Type

According to research, a person’s personality type may be linked to teeth grinding. People who have a markedly negative emotional response to any loss, frustration, or threat and are more self-critical and sensitive to criticism are likely to do this. It may also affect people with overly aggressive, competitive, or hurried personalities.4 5

What to do: If some parts of your personality, say the manner in which you cope with stress, are bogging you down, you can take measures to deal with it. Self-help books about your particular concern can be useful. Cognitive behavioral therapy can also help.6 7 Meanwhile, using a mouth guard can help stop dental damage due to teeth grinding.8

3. Sleep Disorders

Teeth grinding is associated with behaviors exhibited during sleep like mumbling, talking, kicking, or punching while you’re asleep. It’s also linked to sleep paralysis – a condition where you find that you’re temporarily unable to move while you’re falling asleep or waking up. Sleep apnea, a condition where you stop breathing for short periods of time while sleeping, can also be to blame.

What to do: Sleep apnea can be treated by using a breathing device, surgery, and lifestyle changes like quitting smoking and losing weight.9 Following certain healthy sleep habits may also help you get a good night’s sleep.

  • Keep to a regular sleep schedule – go to sleep and wake up at the same time every day.
  • Avoid stimulants like caffeine, alcohol, and nicotine especially close to bedtime. It also helps to avoid having a huge meal late at night.
  • Remove distractions like bright lights, a TV, or computer from your bedroom.
  • Wind down at night with a relaxing bath, soothing music, or a book.10

4. Intestinal Parasites

Studies have found that people infected with intestinal parasites engage in teeth grinding.11 The main kinds of parasites that infect your intestines are helminths like pinworms, tapeworms, and roundworms; and protozoa such as cryptosporidium and giardia. These parasites usually worm their way in when you come in contact with infected fecal matter that is present in contaminated food, soil, or water.12

Parasites can reside in your intestines for long periods without causing any symptoms. When you do experience symptoms, they may include diarrhea, abdominal pain, bloating, vomiting, itching or rash around your anus, weight loss, and fatigue. If the teeth grinding is recent and if you also have some of these symptoms as well, it’s time to see a doctor.

What to do: Your doctor may carry out tests such as a fecal test and recommend appropriate medication.

5. Medications

Teeth grinding can occur as a side effect of some medications, including certain antipsychotics and antidepressants.

What to do: Check with your doctor if find out if any medication that you’re on can cause this side effect. Your doctor may also recommend alternative medication if appropriate.

6. Lifestyle Factors

Some lifestyle factors like having excessive alcohol, using recreational drugs like cocaine or ecstasy, smoking can also up the chances of your grinding teeth. So can drinking a lot of caffeinated drinks like coffee and tea, say 6 cups or more a day.

What to do: Limit your consumption of alcohol or caffeinated drinks. You may need to avoid smoking or the use of recreational drugs to rein in the problem.

7. Improper Teeth Alignment

An improper alignment of your teeth, for instance, caused by a tooth filling that’s too high, can make you grind your teeth.

What to do: Along with teeth grinding, if you feel discomfort or pain or have any other teeth-related problems, visit your dentist. They will be able to correct any dental misalignments.13

8. Teething

Your baby may grind her teeth when she’s teething.14

What to do: This is a temporary phase that’ll pass. But giving your baby a warm cuddle, gently massaging her gums with your finger, or giving her something cold (say, cold carrot sticks) to chew on can help soothe your baby during this period.15
