Teeth grinding, also called bruxism, can be temporary for some people. If it is tied to a short-term trigger like stress, poor sleep, or a recent life change, it may improve once that trigger settles down. But it does not always go away on its own, and for some people it becomes an ongoing habit that needs attention. The National Institute of Dental and Craniofacial Research describes bruxism as a condition involving grinding, clenching, or gnashing that can happen while awake or asleep, and Cleveland Clinic notes that it often happens subconsciously. 
That is why the honest answer is: sometimes, but not always. Mild, occasional grinding may fade. Repeated grinding usually does not get better just because you ignore it. And if it keeps happening, it can wear down enamel, make teeth more sensitive, and contribute to jaw discomfort over time. Cleveland Clinic specifically notes that bruxism can damage your teeth, jaw, and surrounding muscles, and worn enamel can increase sensitivity.
Why bruxism sometimes improves
Bruxism is not always the same from person to person. In some cases, it shows up during a stressful season, a period of poor sleep, or a time when someone is unconsciously clenching more during the day. If the trigger improves, the grinding may ease too. The ADA has reported that many dentists saw increased teeth grinding and clenching during high-stress periods, which supports the connection between stress and bruxism. 
That is one reason some people feel like their grinding comes and goes. It may be worse during certain months, harder life periods, or times when sleep is off. In that sense, yes, it can improve on its own if the underlying cause was temporary.
When it is less likely to go away by itself
If your grinding has been happening for a long time, is happening most nights, or is causing symptoms, it is less likely to simply disappear without some kind of change. That is especially true if you wake up with jaw tightness, headaches, sore teeth, or facial pain. Cleveland Clinic lists jaw pain, headaches, ear pain, and tooth damage among the effects of nighttime grinding.
It is also worth paying attention if you notice:
- Teeth that look flatter, chipped, or worn down
- Increasing tooth sensitivity
- Tension in your jaw when you wake up
- Clicking or soreness in the jaw joint
- A partner hearing grinding at night
Those signs do not automatically mean something serious is wrong, but they are a good reason to talk with a dentist rather than waiting it out. Bruxism can also contribute to temporomandibular joint problems in some people. 
The bigger issue is not just whether it stops
Even when bruxism might eventually settle down, the bigger problem is what happens while it is still going on. Grinding can gradually wear down teeth, strain the jaw muscles, and make existing dental issues worse. NIDCR and Cleveland Clinic both describe bruxism as something that can damage teeth and affect quality of life if it is frequent. 
So the better question is often not just, “Will it go away?” but also, “How do I protect my teeth while it is happening?”
What usually helps
The right solution depends on the cause, but most dentists focus on reducing damage and identifying triggers.
A few common steps include:
- Using a night guard or dental appliance to protect teeth during sleep
- Managing stress if clenching seems stress-related
- Improving sleep habits and bedtime routine
- Checking for bite issues, jaw pain, or signs of sleep-related problems
- Following up with a dentist if symptoms keep going
Cleveland Clinic and the ADA both mention mouthguards or dental appliances as common ways to reduce the damage from grinding, even though they do not “cure” the habit itself. Cleveland Clinic also recommends stress-relief strategies and a regular bedtime routine as part of mananging nighttime grinding. 
A night guard like Remi Custom Night Guard is not there to magically make bruxism disappear overnight. Its main job is to help protect your teeth from the pressure and wear that grinding can cause. That can be especially helpful if your grinding has not gone away on its own, or if you are still figuring out what is triggering it. Cleveland Clinic notes that mouthguards can help treat teeth grinding and help protect your mouth. 
When to call a dentist
It is a good idea to get checked if your grinding is frequent, painful, or starting to affect your teeth. You should also reach out if symptoms are getting worse instead of better. A dentist can look for wear patterns, bite issues, and other signs that your jaw and teeth are under too much pressure. NIDCR advises talking with a dentist about oral habits like grinding and clenching because dentists are familiar with helping patients manage them.
Bottom line
Bruxism can sometimes improve on its own, especially when it is mild or tied to a temporary trigger. But it does not always go away by itself, and it is not something you want to ignore if it is causing tooth wear, sensitivity, headaches, or jaw pain. The safer approach is to pay attention early, protect your teeth, and get help if it keeps happening.
