Teeth grinding (also known as bruxism) can cause a surprising amount of damage if it’s not dealt with properly, sometimes leading to the need for new crowns or even emergency treatment. It can show up as jaw or tooth pain, headaches, sensitivity or worn tooth edges.
Grinding can happen while you sleep, while you’re stressed, or even both. This added pressure puts a lot of strain on your jaw and teeth, and it’s a surprisingly common issue, affecting around 22% of adults around the world.
Understanding the causes is the first step to knowing how to protect your teeth from grinding, as it allows you to spot the signs early. In this article, we look at why it happens and the available ways to keep it in check.
So, how can you protect your teeth from grinding? Well, as we just alluded to, it starts with knowing what’s causing it for you. It rarely happens consciously, which is why it can be so confusing, as for many, it happens while they sleep. Stress and anxiety can also play a big part in unconscious grinding.
Most often, there isn’t going to be a single clear cause, but if you can identify what’s making you do it, you can turn your mind to a solution. That’s what’s going to spare you from the long-term knock-on effects like worn enamel.
Some remedies focus on tackling stress or sleep issues, while others focus instead on protecting your teeth from grinding physically. A lot of patients we see use a combination of methods, depending on severity. The table below shows some of the most common and their limitations.
| Solution | Effectiveness (out of 5) | Limitations? |
| Custom mouthguard from a dentist | ⭐⭐⭐⭐⭐ | None, though stress and anxiety must be treated separately |
| Over-the-counter mouthguard | ⭐⭐⭐ | Fit can be unpredictable, meaning it feels bulky or uncomfortable |
| Improving sleep quality | ⭐⭐⭐ | Can reduce grinding episodes, but teeth remain unprotected |
| Stress management and relaxation | ⭐⭐⭐ | Helps some people, limited impact for others |
| Jaw exercises or physio | ⭐⭐ | Can ease tightness, but no protection for teeth |
Largely speaking, a custom mouthguard from your dentist in Manchester is going to be your best option, as it prevents the issue at source. That means you get a way to reduce the pain and ongoing damage to your teeth, giving you time and space to address any anxiety or sleep issues you might also have.
Even if the habit doesn’t disappear straight away, the teeth and jaw are protected while other contributing factors are addressed.
The problem with night-time grinding is that you’re not there to catch it. You’ll be asleep, your jaw tightens, and whatever force your body produces goes straight through your teeth. That’s why advice about awareness, habits, or “trying to relax” often doesn’t do much.
Mouthguards help because they deal with that moment directly. They sit in the middle and take the impact, which is often what matters most when teeth are already under strain.
Mouthguards aren’t a cure-all for protecting your teeth against grinding, but they can be the difference between comfort and a slow buildup of pain and damage. For many people, they’re what makes bruxism manageable, giving you the freedom to address things in conjunction with your regular check-ups.
It’s easy to ignore things at first when it comes to grinding, but it’s also simpler than you think to get some relief. Jaw pain, headaches, and worn teeth tend to show up gradually, and a good custom mouthguard from your dentist can take all of the urgency out of the situation.
At Ringway Dental, we take time to look at what’s actually happening with your teeth and jaw. If a mouthguard is the right option, you’ll be guided through how it works, how it’s fitted, and the minimal upkeep that’s involved.

Q – Can grinding damage fillings or crowns, or is it just natural teeth?
A – It can affect both. People are often surprised to find a filling feels loose or a crown cracks before the tooth itself hurts. Grinding puts steady pressure on dental work, and over time, that can take its toll.
Q – Why do I get headaches or ear pain if the problem is my teeth?
A – The jaw muscles sit close to the temples and ears. When they’re working overtime through clenching or grinding, the pain doesn’t always show up where you expect it to. That’s why it can feel like a head or ear issue at first.
Q – Will wearing a mouthguard make it harder to breathe at night?
A – A properly fitted guard shouldn’t affect your breathing in any way, shape or form. It’s shaped to sit comfortably on the teeth and stay out of the way, rather than forcing the jaw into an awkward position.
Q – How long do mouthguards usually last before they need replacing?
A – That depends on how hard you grind. Some people get years out of one, others wear through them faster. Either way, a worn guard is usually doing its job by taking the damage instead of your teeth.
Q – Does teeth grinding tend to get worse over time?
A – It can. Some people stay the same for years, others notice it ramp up during stressful periods or when sleep gets worse. That unpredictability is why protecting your teeth against it is so important.
