Bruxism (Teeth Grinding)

You may have heard the term “Bruxism” in relation to grinding teeth. However have you ever wondered exactly what Bruxism is? How it is caused? And how it is treated?

What is Bruxism?

Bruxism is clenchinWhat Is It?g or grinding your teeth. Most people are not even aware that they are doing this. In the United States, bruxism affects about 30 million to 40 million children and adults.

Some people grind their teeth only during sleep. This is called “nocturnal bruxism” or “sleep-related bruxism.” Others grind or clench their teeth during the daytime as well. This is thought to be related to stress or anxiety. Stress can occur for many reasons, including sad and painful events such as the death of a loved one or the loss of a job. It can also occur from joyous events such as a new job or the birth of a baby.

Bruxism can have a variety of causes. Some experts view bruxism as nothing more than a habit. It also can be a result of the body’s reaction when the teeth do not line up or come together properly. Bruxism also can be a symptom of certain rare diseases of the nerves and muscles in the face. In rare cases, bruxism may be a side effect of some medicines that treat depression. These include Prozac (fluoxetine), Zoloft (sertraline) and Paxil (paroxetine).

People with severe bruxism can break dental fillings or damage their teeth. Rubbing the teeth together can cause the outer layers of enamel to wear away, exposing dentin. This can result in tooth sensitivity. Severe bruxism also has been blamed for:

  • Some cases of jaw dysfunction, also called temporomandibular disorders (TMD)
  • Headaches when you wake up in the morning
  • Unexplained facial pain


You may be a bruxer if you experience any of the following:

  • Rhythmic contractions of the jaw muscles
  • A grinding sound at night, which may disturb the sleep of someone who shares a bedroom with you
  • A dull morning headache
  • Jaw muscles that are tight or painful – This can make it uncomfortable, even painful, to open your mouth wide, especially in the morning
  • Long-lasting pain in the face
  • Damaged teeth, broken dental fillings and injured gums
  • Painful jaw joint
  • Swelling (occasionally) on the side of your lower jaw caused by clenching. Chronic clenching exercises the jaw muscles. Like lifting weights, this makes the muscles grow larger. Once you stop clenching, the muscles will shrink and the swelling will go away.

If you experience any of these signs and symptoms, see your dentist. He or she can determine if you are a bruxer and how best to treat it.

Your dentist will ask about your general dental health, what sources of stress you have in your life, and what medicines you take. If you share your bedroom, the dentist also may want to talk to that person. The dentist will ask about your sleep habits, especially about any unusual grinding sounds heard during the night.

Your dentist will examine you, paying special attention to the muscles in and around your jaw. The dentist also will look at your teeth for evidence of grinding. During this examination, your dentist will check for tenderness in your jaw muscles and the jaw joint. He or she also will look for broken teeth, missing teeth and poor tooth alignment.

A more detailed exam may follow if your dentist suspects that your bruxism is related to dental problems. In addition to checking your “bite,” (how your upper and lower teeth come together) the dentist will examine your teeth and gums for damage caused by bruxism. Your dentist might also take X-rays of your teeth and jaws.

About 30% of children grind or clench their teeth. The rate is highest in children under age 5. If your child grinds or clenches his or her teeth, discuss the problem with your family dentist. Most children eventually outgrow bruxism and suffer no permanent damage to their teeth.

Expected Duration

Of all children who brux between the ages of 3 and 10, more than half will stop on their own by age 13.

In teenagers and adults, how long bruxism lasts depends on its cause. For example, bruxism can last for many years if it is related to stress that doesn’t go away. However, if bruxism is being caused by a dental problem, it should stop when the teeth are repaired and realigned. Often this occurs within a few dental visits.

If your bruxism is related to stress, professional counseling may help. You also can try strategies to help you relax. It may help to cut down on stimulants such as tobacco and caffeine.

In both children and adults, tooth damage related to bruxism can be prevented. The usual method is to wear a night bite plate or a bite splint (a dental appliance worn at night to stop teeth grinding). Wearing a bite splint also can help relieve pressure on facial muscles and the jaw joint. Hot compresses on facial muscles may help relieve some of the muscle pain and tightness that bruxism can cause.


The treatment of bruxism varies depending on its cause:

Stress — If your bruxism is stress-related, your dentist or physician may recommend professional counseling, psychotherapy, biofeedback exercises or other strategies to help you relax. Your dentist may prescribe a medicine such as diazepam (Valium). This will be for short- term use, usually one week or so. It should be taken at night before you go to bed to help reduce grinding at night. You also may receive a prescription muscle relaxant to temporarily ease the spasm in your jaw. You may also be fitted for a custom-made bite plate. If this does not help, your dentist may refer you to an oral surgeon or to a dentist who has advanced training in head and neck pain.

Dental problems — If your bruxism is related to tooth problems, your dentist probably will correct tooth alignment. In severe cases, your dentist may need to use onlays or crowns to entirely reshape the biting surfaces of your teeth. The dentist also may make a mouth guard or bite splint that fits your mouth and teeth. This will help prevent further damage to the teeth. In some cases, it may help your teeth and muscles to realign.

Medicines — If you develop bruxism as a side effect of antidepressant medicines, you have a couple of options. Your doctor may switch you to a different drug or give you another medicine to counteract your bruxism.

When To Call a Professional

Call your physician or dentist if you have symptoms of bruxism, or if you are told that you grind your teeth while you sleep.

See your dentist right away if you break a tooth, lose a filling, or notice that your teeth are becoming loose.


Even without special treatment, more than half of young children with bruxism stop grinding their teeth by age 13. Meanwhile, your dentist can fit your child with a night bite plate to prevent excessive tooth wear. This device is effective in almost all children who use it as directed.

In teenagers and adults, the outlook is excellent if bruxism is treated properly and in a timely manner.

What is a Veneer?


Figure 1: Right front tooth has a large discoloured filling and it is shorter than the left front tooth.


Figure 2: Result after teeth whitening and a porcelain veneer on the right front tooth.

A veneer is a porcelain facing that is permanently bonded onto the front of the tooth.  The purpose of the veneer is to improve the aesthetics when we desire a colour change in the tooth or when we need to change the contour or shape of a tooth.  In the above example, the first picture shows the patient’s right front tooth that has poor aesthetics due to a large filling.  It is also shorter than the left front tooth.

After treatment with the veneer, we can see that the lengths of the teeth are equal and that the porcelain has completely masked the discoloured filling.  In addition, the patient had their teeth whitened, improving the overall esthetics of the smile.

If you have any questions regarding improving your smile with veneers, please do not hesitate to contact us.

Immediate Implants

Picture4Picture3Picture2Picture1An immediate implant is an implant that is placed directly after a tooth extraction.  Often a temporary tooth is placed on the implant the same day so that the patient does not have to be without a tooth. The treatment can be successful but requires proper case selection and diagnosis. The series of pictures above illustrate an immediate implant placement at Soho Dental. Figure 1 shows an upper pre-molar tooth that is fractured and cannot be repaired as the fracture extends far below the gums.  Figure 2 is an x-ray that shows the implant placement after the tooth was extracted.  Figure 3 shows the implant in the mouth immediately following extraction.  Figure 4 shows the temporary crown that was placed on the implant the same day. The implant was left to heal for 3 months before a permanent porcelain crown was placed.

Please let us know if you have any questions about immediate implants!

Continuing my education in order to better serve you…

This week I have been away from the office to complete part 6 of the core curriculum at the Dawson Academy for Advanced Dental Study. The Academy teaches the essential principles and skills for complete dental care with primary concentrations in dental occlusion, the temporomandibular joints and comprehensive esthetic restorative dentistry.

This has been a journey which started in January 2015 and that I hope to complete in April 2016. The Dawson philosophy is to train dentists to be true “physicians of the masticatory system”. This is my personal commitment to all our patients at Soho Dental and in doing so, I hope to provide for you the very best in dental care!
