Tuy nhiên, bạn có thể áp dụng một số biện pháp tại nhà và nhờ sự hỗ trợ của nha sĩ để giảm thiểu tình trạng này. Nếu bạn muốn tìm hiểu cách chấm dứt tật nghiến răng vào ban đêm, hãy bắt đầu với Bước 1 dưới đây.
Các bước
Xác định Bạn có Tật nghiến răng khi Ngủ

Hiểu rõ thế nào là nghiến răng. Nghiến răng là hành động cắn chặt hoặc siết hai hàm răng lại với nhau một cách không tự chủ. Tình trạng này thường xảy ra trong lúc ngủ và có liên quan đến căng thẳng trong cuộc sống hàng ngày. Một số người có thói quen siết răng cả ngày, nhưng nghiến răng chủ yếu xảy ra vào ban đêm. Điều này khiến việc tự nhận biết tật nghiến răng trở nên khó khăn.

Check for unusual symptoms as soon as you wake up. Since teeth grinding often occurs at night, it's a good idea to look for any abnormal signs in the morning. While self-diagnosis isn't straightforward, the following symptoms can help confirm if you have a teeth-grinding habit:
- Persistent, dull headaches
- Sore jaw
- Audible grinding sounds even after falling asleep
- Teeth sensitivity to hot, cold, or brushing
- Gum inflammation (gingivitis)
- Injuries inside the cheeks (from grinding or biting)

Ask your partner. If you share a bed with your partner, inquire if they've heard any grinding noises while you sleep. You can ask them to wake up earlier or stay up later to observe any signs of teeth grinding. If they wake up during the night, they might notice symptoms you're unaware of.
- If you sleep alone but still want to check for symptoms, consider recording your sleep to listen for any grinding or clenching sounds.

Visit a dentist. If you suspect you grind your teeth, consult a dentist. They will examine your mouth and jaw for signs like jaw pain or worn-down teeth. Once confirmed, you can explore home remedies or professional treatments to address the issue. The dentist will also check for other potential causes of discomfort, such as:
- Dental issues
- Ear infections or inflammation
- TMJ or TMD (Temporomandibular Joint Disorder)
- Medication side effects
Home Remedies for Treatment

Reduce stress. Stress is a leading cause of teeth grinding. Focus on alleviating daily pressures by attending stress management sessions, exercising, or practicing meditation. Here are some effective ways to reduce stress:
- Eliminate stress triggers from your life. If a toxic roommate or relationship is causing tension, remove these negative influences and move forward.
- Maintain a consistent sleep schedule. This habit will boost your energy and help you tackle daily challenges.
- Spend time with friends. Laughing and enjoying their company can help you relax and relieve pressure.
- Eat balanced meals. Three nutritious meals a day can help you feel more stable and less sensitive to stressors.

Avoid caffeine in your diet. Stop consuming soda, coffee, and limit excessive chocolate intake. Caffeine is a stimulant that, in large amounts, can make it difficult to relax your mind and jaw muscles, especially at night.

Stay away from alcoholic beverages. Alcohol is a depressant that disrupts healthy and deep sleep. Teeth grinding can worsen after consuming alcohol. While it may help you fall asleep faster, alcohol prevents restful and deep sleep, increasing the likelihood of grinding your teeth.

Stop chewing on non-food items. Break habits that involve using your mouth to relieve stress. For example, if you tend to chew on pens when stressed, stop this habit immediately. If it's challenging, start by chewing gum or sucking on mints when the urge arises, then gradually eliminate the habit.

Train yourself to avoid clenching your jaw during the day. If you notice your jaw is tense or your teeth are frequently clenched, relax your jaw by placing the tip of your tongue between your teeth.

Add calcium and magnesium supplements to your diet. Calcium and magnesium are essential for muscle function and nervous system health. If your diet lacks these nutrients, you may experience teeth grinding, stress, and muscle pain.
- This home remedy may take around 5 weeks to show noticeable effects.

Relax before bedtime. This is crucial for alleviating stress before going to bed, helping you feel more at ease in the evening, and thereby reducing the risk of teeth grinding. Here are some effective ways to unwind before sleep and achieve a deeper, more peaceful rest:
- Massage your neck, shoulders, and facial muscles before drifting off. Use your fingers and palms to gently knead the sides of your head, forehead, and jaw to improve blood circulation.
- Soak a towel in hot water, wring it out, and place it on your cheeks near your ears. This will help relax and loosen your muscles.
- Similarly, drape a warm towel over your entire face. This not only relaxes your muscles but also calms your mind.
- Play soft music or white noise to help your mind relax as you fall asleep.
- Read a book in bed for at least half an hour before sleeping. This beneficial habit will prepare you for a restful slumber.
- Turn off the TV, computer, and any bright lights at least an hour before bed. Minimize sensory stimulation to ease into sleep.
Professional Treatment Methods

Seek help from a dentist. If your teeth grinding persists, you should consult a dentist, as chronic grinding can lead to cracked, loose, or lost teeth. If you grind your teeth frequently, it may be time to consider treatments like bridges, crowns, root canals, implants, partial dentures, or even a full set of dentures. Your dentist will evaluate and recommend the best treatment for you. Depending on the severity of your symptoms, here are some treatments your dentist might suggest:
- Muscle relaxants. While medication is rarely used to treat teeth grinding, muscle relaxants or Botox injections can sometimes help relax your jaw muscles and prevent grinding.
- Crowns or onlays for teeth. If grinding has caused significant damage, your teeth may no longer align properly. In such cases, your dentist may recommend onlays or crowns to restore the shape of your teeth and improve your bite.

Get a custom-fitted night guard or splint from your dentist. Your dentist may recommend a night guard or splint to protect your teeth from wear and damage caused by grinding. Here’s some important information about these devices:
- Night guards can be custom-made by your dentist or purchased over-the-counter. However, over-the-counter options are often soft and may slip during grinding. Custom-fitted guards, though more expensive (often covered by insurance), provide a better fit and greater comfort.
- Some self-adjusting guards made from ethylene vinyl acetate (EVA) are an affordable option to try before investing in a custom guard. These can be softened in hot water and molded to fit your teeth.
- Splints are made from hard, clear acrylic and are designed to fit over your upper or lower teeth. Wearing them at night can protect your teeth from damage.

Consider external orthodontic adjustments (optional). If teeth grinding has affected the appearance of your teeth and you’re eager to change that, don’t hesitate to consult a cosmetic dentist. If your teeth have become shorter or closer to the gums due to grinding, your dentist can reshape or rebuild them using crowns or veneers. These cosmetic procedures will restore your teeth’s appearance, making them stronger and more attractive.
Advice
- When your mouth is closed, avoid letting your teeth touch. They should only interact when you're chewing or swallowing.
- While ice is often used to soothe pain, it's not suitable in this case. Ice can tighten your jaw muscles, leading to more discomfort later. Instead, use a warm towel on your face, as mentioned earlier.
- If your jaw hurts, you can take pain relievers like ibuprofen to temporarily ease the discomfort.
Warning
- Chronic teeth grinding can lead to cracked, loose, or even broken teeth. Additionally, this habit can severely impact your jaw and cause temporomandibular joint disorder (TMJ). Therefore, if you frequently grind your teeth uncontrollably, it's best to see a dentist immediately.
- Some people develop teeth grinding after starting antidepressant medication. If you're in a similar situation, consult your doctor to see if you can switch medications or take treatment for bruxism.
