16 Jul How to Avoid Grinding Teeth at Night
Teeth grinding at night, known as sleep bruxism, often happens without you realising it. You may not be able to stop it through willpower because it occurs during sleep. However, you can reduce its effects by managing stress, improving sleep habits, avoiding evening stimulants and using a dentist-made night guard where appropriate. You should also speak to a dentist if you have worn teeth, jaw pain, morning headaches or damaged fillings. Loud snoring, choking during sleep or daytime exhaustion may need a medical assessment for sleep apnoea.
Waking with a tight jaw, sore face or dull headache can make mornings unpleasant. In some cases, a partner may hear grinding noises during the night before the person doing it notices anything.
Occasional clenching may cause no lasting harm. Regular or forceful grinding, however, can wear down enamel, chip teeth, damage fillings and place extra strain on the jaw muscles.
The most useful approach is not to search for one instant cure. It is to identify possible triggers, protect the teeth and deal with any related sleep, stress or medical concerns.
What Is Night-Time Teeth Grinding?
Teeth grinding is medically known as bruxism. It involves clenching the jaw or moving the teeth against each other. It can happen while you are awake or asleep.
Sleep bruxism is difficult to control consciously because you are unaware of it. This is why simply telling yourself to relax before bed may not be enough.
A dentist may notice the signs during an examination. These can include flattened biting surfaces, small enamel cracks, chipped edges, sensitive teeth, worn fillings and tenderness in the jaw muscles. Some people also wake with headaches around the temples or discomfort near the ears.
What Causes Teeth Grinding at Night?
There is not always one clear cause. Stress and anxiety are common contributors, particularly during busy or emotionally difficult periods. Some people also clench while concentrating during the day, and that tension may continue into sleep.
Poor sleep, irregular sleeping hours, alcohol, smoking and high caffeine intake may make symptoms worse for some people. Certain medicines, including some antidepressants, may also be linked with grinding. Never stop prescribed medicine yourself; speak to the clinician who prescribed it if you notice symptoms after starting or changing a dose.
Sleep bruxism can also occur alongside sleep disorders. If you grind your teeth and also snore loudly, wake choking, stop breathing during sleep or feel extremely tired during the day, speak to your GP. These signs may suggest obstructive sleep apnoea and should not be managed with a basic mouthguard alone.
Can You Completely Stop Grinding Your Teeth?
Not always. Treatment depends on what is causing or worsening it. A night guard can protect your teeth, but it may not remove the underlying grinding habit.
This is an important point that many online articles miss. They often present a guard as a cure, when its main purpose is usually to place a protective layer between the teeth. It can reduce wear, fractures and damage to dental restorations, but you may still clench your jaw while wearing it. A complete plan may include dental protection, stress management, better sleep routines and treatment of any related medical or sleep problem.
Reduce Stress Before Bed
Stress is not the only cause of bruxism, but reducing tension can still help. Try to give yourself a calm period before sleep rather than moving directly from work, emails or social media into bed.
Slow breathing, gentle stretching, reading or taking a warm shower may help the body settle. If anxiety is persistent or affecting daily life, speaking to a GP or trained therapist may be more useful than relying on relaxation tips alone.
It also helps to notice daytime clenching. Your teeth should normally be slightly apart when your jaw is resting. Place reminder notes near your desk or phone with a simple message such as: “Lips together, teeth apart.” Reducing daytime jaw tension may make you more aware of the habit overall.
Improve Your Evening Routine
A regular sleep schedule supports better-quality rest. Try to go to bed and wake at similar times, keep the bedroom dark and quiet, and reduce screen use shortly before bedtime. Limit caffeine later in the day, particularly coffee, strong tea, energy drinks and cola. Alcohol may make you sleepy at first, but it can disturb sleep later in the night. Smoking nicotine and tobacco can affect sleep, and be harmful to your oral health. While these changes will not guarantee that grinding will stop, they can reduce common triggers to improve sleep.
Avoid Overworking the Jaw
If your jaw feels sore, avoid chewing gum, biting your nails or chewing pens. Very hard and chewy foods can add further strain when the jaw muscles are already tired.
During a painful flare-up, softer foods may be more comfortable. A warm compress against the side of the face can relax tight muscles. Gentle jaw movements may help some people, but avoid forcing the mouth open or carrying out aggressive exercises without professional advice.
Ask About a Custom Night Guard
A dentist may recommend a mouthguard, bite guard or occlusal splint. It is worn over the upper or lower teeth during sleep and is made to protect them from direct grinding forces. A custom appliance is created from a scan or impression of your mouth. It should fit more securely than a shop-bought sports guard. Poorly fitting guards may feel uncomfortable and can irritate the gums or affect the bite, so professional assessment is important. Do not use a sports mouthguard as a long-term substitute unless advised by a dental professional. Sports guards and bruxism splints are designed for different purposes. Clean the appliance according to your dentist’s instructions, store it in a ventilated case and bring it to dental reviews so its fit and wear can be checked.
When Should You See a Dentist?
Arrange an appointment if you have regular morning jaw pain, headaches, sensitive teeth, chipped teeth, cracked fillings or visible tooth wear. You should also seek advice if your jaw locks, opening becomes difficult or pain affects eating.
A dentist can examine your bite, jaw muscles, teeth and restorations. If you have symptoms that suggest jaw or sleep disorders, they may recommend a protective device, repair damaged teeth or refer you to a specialist for further evaluation. Seeking help early matters because enamel lost through grinding does not naturally grow back.
Twenty Twenty Dental at Salisbury Dental Services
Twenty Twenty Dental in Salisbury can assess common signs of night-time grinding, including worn enamel, cracked teeth, damaged fillings, sensitivity and jaw discomfort. A dental team will examine your bite to determine if a night guard can help protect your teeth.

An early assessment can help to prevent more wear and more complicated restorative treatments.
Protect Your Smile While Addressing the Cause
Avoiding teeth grinding at night is not always as simple as changing one habit. Because it happens during sleep, the most realistic goal is often to reduce known triggers, protect the teeth and investigate anything that may be disturbing sleep.
Start by improving your evening routine, reducing daytime clenching and arranging a dental check if symptoms continue. A personalised plan is far safer than relying on a generic mouthguard or ignoring the problem until a tooth breaks.
FAQs
How do I know if I grind my teeth at night?
Common clues include morning jaw tightness, headaches around the temples, sensitive teeth, chipped edges and a partner hearing grinding noises. A dentist may also identify wear during an examination.
Can stress cause night-time teeth grinding?
Stress and anxiety can contribute, although they are not the only possible causes. Sleep problems, lifestyle habits and some medicines may also be involved.
Will a night guard stop me grinding?
A night guard mainly protects the teeth from wear and fractures. It may reduce discomfort for some people, but it does not always stop the jaw muscles from clenching.
Can I buy a night guard from a shop?
Ready-made guards are available, but they may fit poorly. A dentist-made guard is shaped for your mouth and can be checked to ensure it does not harm the teeth, gums or bite.
Should I see a GP or a dentist?
See a dentist for tooth wear, broken fillings, sensitivity or jaw pain. Speak to a GP if you also have loud snoring, breathing pauses, choking during sleep or severe daytime tiredness.
Can teeth grinding damage crowns and fillings?
Yes. Repeated pressure can chip natural teeth, crack fillings, damage crowns and wear through dental appliances. Regular reviews help identify early damage.
