Waking up with a sore jaw or noticing that your teeth look shorter than they used to are symptoms most people do not connect with teeth grinding. But if you grind or clench your teeth at night, these are often the first signs.
Bruxism is the term for teeth grinding or clenching, which can occur while a person is awake or asleep. It can also change the way the upper and lower teeth meet. This change often develops slowly enough that many people do not notice it until a dentist identifies it.
How Does Teeth Grinding Wear Down Your Teeth?
Every time you clench or grind, your teeth are grinding against enamel that’s meant to last a lifetime with normal use. Bruxism puts far more pressure on that enamel than everyday chewing ever does, and it usually happens at night, when you have no control over it.
Over months and years, this wears down the biting surfaces of your teeth, flattening edges that used to have natural ridges and points. Once that surface changes, the way your teeth fit together changes with it.
Why Your Bite Starts to Change
Your bite depends on the shape of your teeth and how they align with one another. When grinding flattens or chips those surfaces unevenly, your jaw may adapt by closing into a different position. Some teeth wear faster than others depending on how you grind, so the change in your bite can be uneven. One side of your mouth might feel higher or lower than the other, or your front teeth may make contact earlier than before when you bite down. The process is gradual, but the effects build over time.
Signs Your Bite May Have Changed
Several warning signs may appear before a person realizes that the bite has changed. These include:
- Teeth that appear shorter or flatter than before
- Jaw soreness or stiffness in the morning that persists
- A bite that feels uneven or different
- Tooth sensitivity, since worn enamel can expose the underlying dentin
None of these signs is dramatic on its own, but together they may indicate that grinding has been occurring for some time. Because other conditions can cause similar symptoms, a dental evaluation is needed for diagnosis.
How Is Bruxism Treated?
Treatment starts with finding the cause. Stress is a common one, but sleep disorders such as sleep apnea, some medications, and caffeine or alcohol can also contribute. A night guard is among the treatments dentists recommend most often for protecting teeth from grinding.
Worn between the upper and lower teeth during sleep, a custom-fitted guard acts as a barrier that spreads out biting force and shields the remaining enamel from further wear. It does not stop the grinding itself.
When the bite has already changed substantially, orthodontic or restorative care may be needed to bring it back into balance, and the sooner the problem is found, the more conservative that treatment tends to be.
Final Thoughts
Bruxism often develops without obvious symptoms, so bite changes can go unnoticed for years.
