Many people clench or grind their teeth, mostly during sleep, without realising it. A splint is a custom-made clear appliance worn over the teeth. It protects them from wear and can help relieve the chewing muscles.

What it is

Bruxism is clenching or grinding the teeth, either asleep or during the day. It is often linked to stress and tension, but also to sleep disorders, certain medicines, smoking, alcohol and caffeine.

A splint (also called a night guard or occlusal splint) is made from hard, clear acrylic in a dental laboratory, from impressions of your own teeth. It does not necessarily stop the clenching, but it absorbs the forces, protects teeth and restorations from wear and cracks, and helps the muscles relax.

It is different from the soft guards used in sport and from ready-made products, which do not fit your bite precisely.

When it may be needed

Worn, flattened or cracked teeth, broken fillings.
Aching or tired facial muscles in the morning.
Pain, clicking or noises from the jaw joint (just in front of the ear).
Headaches at the temples in the morning, or pain near the ear.
Someone who sleeps next to you hears grinding.
To protect extensive restorations, veneers or crowns in people who clench.

Jaw pain can have other causes too, so an examination is needed before making any splint.

What usually happens

Examination. We check your teeth for wear, the chewing muscles, the movement and sounds of the jaw joint, and your bite.
Impressions. We take impressions and a record of your bite.
Making the splint. It is made in the laboratory, usually within a few days.
Fitting. We try it in and adjust it so that your teeth touch it evenly.
Review. After a few weeks we check how you are getting on and whether any adjustment is needed.

Afterwards

For the first few nights the splint may feel strange or make you produce a little more saliva. Most people get used to it quickly.
Clean it every morning with a soft toothbrush and cold water (not hot, to avoid distortion) and keep it in its case.
Bring it to your routine visits so we can check its wear and fit.
If clenching is linked to stress or sleep problems, talking to your doctor may also help.

Frequently asked questions

Will I have to wear it for ever?

That depends on the cause. Some people need it for weeks or months until symptoms settle. People who clench regularly during sleep often wear it long term as protection.

Can I buy a ready-made guard?

Ready-made products do not fit your bite precisely and in some cases may put extra strain on the jaw joint. A custom splint is adjusted to your own teeth.

Will it stop my jaw pain?

It helps many people, but no one can promise a result. For persistent pain, working with other professionals may be needed, for example a physiotherapist or a colleague with a special interest in jaw joint disorders.

How long does a splint last?

It depends on how hard you clench. We check it at every visit and replace it when it is worn or when your teeth change (for example after new crowns).
