Signs You May Be Grinding or Clenching Your Teeth

Have you noticed that the edges of your teeth look flatter than they used to? Maybe you wake up with a sore jaw, experience frequent headaches, or have developed tooth sensitivity without knowing why. You could be grinding or clenching your teeth.

Teeth grinding, also known as bruxism, can happen while you are awake or asleep. Because nighttime grinding happens unconsciously, many people do not realize they are doing it until a dentist notices signs of wear. Understanding the symptoms can help you address the problem before it causes more significant damage.
What Is Bruxism?
Bruxism is the involuntary grinding, clenching, or pressing together of the teeth.
Some people clench their teeth during the day, particularly when concentrating or experiencing stress. Others grind their teeth while sleeping and have no idea it is happening.
Occasional grinding may not cause significant problems. Frequent or forceful grinding, however, can place considerable pressure on your teeth and jaw.
Over time, that pressure can take a toll.
Signs You May Be Grinding Your Teeth
You do not have to hear yourself grinding to have bruxism. Some common signs include:
Some people may have only one or two of these symptoms.
Why Does Grinding Wear Down Your Teeth?
Your teeth are designed to handle the forces involved in normal chewing. Grinding and clenching can expose them to repeated pressure outside of normal eating. Over time, this can gradually wear away enamel. As enamel becomes thinner, teeth may appear shorter, flatter, or more uneven. The underlying layers of the tooth may also become more exposed, which can contribute to sensitivity. Severe grinding can potentially lead to cracks, fractures, or damage to existing dental restorations.
What Causes Teeth Grinding?
There is not always one obvious cause. Bruxism may be associated with several factors, including stress or anxiety, sleep-related issues, certain medications, lifestyle habits, or other individual factors. Because the cause can vary from person to person, a dental evaluation can be an important first step in determining what may be contributing to your symptoms.
How Does a Dentist Know If You Grind Your Teeth?
Your dentist may be able to spot evidence of grinding during a routine dental exam, even if you have never noticed symptoms yourself.
They may look for:
Unusual patterns of enamel wear
Flattened biting surfaces
Small fractures or chips
Changes to existing dental work
Tenderness in the jaw muscles
Other signs of excessive pressure on the teeth
Your dentist may also ask about headaches, jaw discomfort, sleep habits, and other symptoms to get a more complete picture.
Can a Night Guard Help?
For some patients who grind their teeth while sleeping, a night guard may be recommended. A properly fitted night guard creates a protective barrier between the upper and lower teeth. It does not necessarily eliminate the underlying cause of grinding, but it can help protect the teeth from continued wear and damage.
Your dentist can determine whether a night guard is appropriate for you and discuss the options available.
Don't Ignore Changes in Your Teeth
Because tooth wear usually happens gradually, it can be easy to overlook.
If your teeth appear shorter or flatter, you frequently wake up with a sore jaw, or you are experiencing unexplained sensitivity or headaches, mention it at your next dental visit. Identifying grinding early may help protect your natural teeth and existing dental work from additional damage.
