Night Guard KL: Teeth Grinding Signs, Options and Cost
Do you wake up with a sore jaw or a dull headache? You may be grinding your teeth in your sleep. If you are looking for a night guard KL patients can get quickly, Teethos Dental in Chinatown makes custom guards for RM350 per arch, including your consultation and mould.
This guide covers the signs, the causes, your options and what to expect at your visit. For a quick summary, see our night guard page.
What is teeth grinding (bruxism)?
Bruxism is the medical name for grinding or clenching your teeth. It can happen during sleep or during the day, often when you are stressed or concentrating.
Occasional clenching is common. When it happens often, it can wear your teeth down and leave your jaw muscles tired.
What are the signs that I grind my teeth at night?
Grinding usually happens while you sleep, so you tend to notice the effects rather than the grinding itself. Common signs include:
A sore, tight or tired jaw when you wake up
Morning headaches, especially around the temples
Teeth that look flatter, shorter or chipped at the edges
Teeth that feel more sensitive than before
A partner hearing grinding noises at night
Catching yourself clenching during the day
These signs can have other causes too. Sensitivity, for example, has several possible reasons, which we explain in our guide to tooth sensitivity causes and solutions. A dental check is the easiest way to know for sure.
What causes teeth grinding?
There is often no single cause. Grinding is commonly linked with stress, poor sleep, caffeine, alcohol, smoking and the way your teeth bite together.
Some medications and sleep conditions can also play a part. If you snore heavily or wake up tired after a full night's sleep, tell your dentist. They may suggest you see a doctor as well.
Can teeth grinding cause jaw pain?
It can contribute. Clenching puts extra load on your jaw muscles and jaw joints (TMJ), so some people notice pain, clicking or stiffness.
Jaw pain has many possible causes, though. If your jaw hurts, clicks, locks or is hard to open, see a dentist so it can be properly assessed. Pain that is worse at night can also come from a tooth, which we cover in why a tooth hurts only at night.
How is teeth grinding managed?
A dental check comes first. Your dentist looks at the wear on your teeth, your jaw muscles and your bite, then talks you through options such as:
A custom night guard to protect your teeth while you sleep
Looking at triggers, such as stress, sleep, caffeine or alcohol
Repairing damage, such as chipped or worn teeth, where needed
Referral to a doctor if a sleep or breathing problem is suspected
Jaw (masseter) injections for some people who clench heavily (see below)
Does a night guard stop teeth grinding?
Not necessarily. A night guard protects your teeth rather than curing the habit.
It sits between your upper and lower teeth, so the guard takes the wear instead of your enamel. Your dentist can talk you through what may be behind your grinding.
Hard or soft: which night guard is right for me?
We offer both, and your dentist will recommend one based on your teeth and what feels comfortable:
Hard night guards are firmer and are often suggested for heavier grinders.
Soft night guards feel more cushioned, and some people find them easier to get used to.
Is a custom guard better than a pharmacy mouth guard?
Pharmacy mouth guards are cheaper and quick to buy, but they are made to fit many mouths, not yours. They can feel bulky or move around, so some people stop wearing them.
A custom night guard is made from a mould of your own teeth, so it fits closely and is designed for sleeping in. A sports mouthguard is a different product, built to protect against knocks during sport.

We are open Monday to Friday, 9am–6:30pm, and Saturday and Sunday, 9am–5:30pm.
Bring your guard to your regular check-ups so we can check its fit. Many patients book it alongside teeth scaling and polishing.
Are jaw (masseter) injections an option for grinding?
Some people who clench heavily ask about jaw injections. At Teethos, Dr Lynn Tung Li Ying offers masseter injections, where a small amount of botulinum toxin is placed in the large chewing muscle at the side of your jaw. This relaxes the muscle and may reduce how hard you clench.
It is temporary. The effect wears off gradually and varies from person to person.
It can be used alongside a night guard. The injection works on the muscle, while the guard protects your teeth.
It is not right for everyone. Dr Lynn assesses you at a consultation first.
Price: RM1,500 with a Korean brand, or RM2,500 with Allergan (US).
To ask whether it suits you, message us on WhatsApp.
