Grinding teeth in sleep wears down enamel and causes sensitivity and jaw pain. A night guard is a way to protect the teeth at night that many people are advised to use by their dentist.
- A night guard is a clear plastic piece made to your teeth and worn in sleep so the teeth do not grind directly against each other.
- It does not cure the cause of grinding but it protects enamel and reduces jaw pain.
- Flattened or sensitive teeth, a tired jaw on waking or morning headaches are signs a dentist may advise one.
- Rinse it with cool water each morning, store it dry in its own case and have regular check-ups to check wear.
Many people grind their teeth in their sleep without knowing it, only noticing a tired jaw, a headache or sensitive teeth in the morning. A night guard is a device that protects the teeth while you sleep. This article explains what it is, who needs one and how to use it properly.
What is a night guard?
It is a thin, clear piece of plastic made to the mold of your own teeth and worn over the upper or lower teeth during sleep. It creates a cushion between the two jaws so the teeth do not grind directly against each other.
A night guard does not cure the cause of grinding, but it reduces damage to the enamel and the jaw muscles. See is grinding teeth in sleep harmful.
Who should use a night guard?

- A tired jaw on waking, pain around the ear or morning headaches.
- A partner who hears grinding at night.

How do I use a night guard properly?
- Wear it every night before sleep, after brushing your teeth.
- Give yourself a few days to get used to it: at first it may feel bulky and make you produce more saliva, which usually settles.
- Return when the dentist asks so it can be adjusted if it feels tight or loose.
- Have regular check-ups so the dentist can check wear on the guard and on your teeth.
Cleaning and storing the guard
- Rinse it with a soft brush and cool water each morning. Avoid hot water, which can warp it.
- Let it dry and keep it in its own case, away from heat such as direct sunlight.
- Keep it away from pets and do not share it with others.
- Replace it if it cracks, wears through or no longer fits.
