How do Dental Splints work?

Dental splints are a mouthguard for you to sleep with. They work by acting as a barrier between your teeth, this can help reduce the muscle activity of your grinding muscles and protect your teeth from wearing themselves down. Splints can also be made to position your jaw forward while you sleep, this makes your airway bigger. A bigger airway let more air through, and can help to stop snoring and reduce sleep aopnea. The result you are looking for will determine how the dental splint is made and customised to your mouth. As a result of this, it's easy to see why a dental splint needs to be precisely customised to both your mouth and jaw and also to your bite in order to achieve the results that you want.

What is the Difference Between a Mouth Guard and a Splint?

A mouth guard generally refers to the protective covering for sports. It is custom fit to your teeth, and can be different thickness depending on what you are using it for. The bite is generally not customized with a mouth guard. Like most things thought there is more to the mouth guard than you may first think.

A splint is usually made through taking an impression of both your top and bottom teeth. You will then receive a plaster cast like in the picture below.

Is a Splint for Grinding or Snoring?


depending on how the splint is made determines what it's purpose is. If the splint is designed to move the jaw into a position which keeps the airways clear whilst sleeping, then this will be useful to stop snoring.

How Does a Splint Stop Grinding?

A well designed dental splint for grinding will help guide your jaw into a position where it can relax a bit more. The protective splint then absorbs the pressure that is created through the grinding and dissipates it through the whole splint. As a result your teeth are both protected from the grinding of the teeth and the jaw itself is under less pressure. This will let you have a better sleep and protect your teeth from being ground down.

How Can I Tell if I Need a Splint

Have you been told that you snore whilst sleeping?

Have you woken up with a sore jaw, and feels like you were clenching?

Has your dentist said that your teeth have been grinding down?

If so, getting a dental splint could be what you require. A dental splint may resolve mild sleep apnoea. Sleep apnoea occurs when the throat is partially or completely blocked whilst asleep. If left untreated, you can wake up in the morning feeling tired and unrested. This is due to interrupted sleep and the stopping of breathing multiple times per hour during the night. It is important to treat this condition, as sleep apnoea if left untreated, can lead to 

  • higher risk of diabetes

  • stroke

  • headaches

  • depression

  • lower libido in men and impotence

Of course this isn't to mention also that tiredness can lead to a decrease in overall mood and well being and risks of accidents in the vehicle and workplace associated from this.


A Night Guard can fix snoring and mild sleep apnoea

On the other side of things, the dental splint can also help with symptoms of bruxism (grinding of teeth) during sleep. Bruxism generally happens during the night whilst you sleep, so in most cases you won't actually be aware that you are doing it. If you experience any of the following symptoms, please talk to the dentist about a dental splint.

  • Abraded teeth (teeth starting to lose enamel through physical force)

  • Jaw pain (could extend to facial pain)

  • Sensitive teeth

  • Tense muscles in the facial region

  • Dislocation of the jaw.

  • Popping or clicking

  • Headaches

  • Lock jaw

  • Smooth areas on the biting surface from rubbing (wear facets)

If left untreated, the enamel itself could be worn away to the dentine of the tooth. Chips and cracking of the teeth can occur. The clicking or locking of the jaw can lead to dislocation and a restricted range of motion of the mouth.

The other thing that may happen over time is that the structure of your face itself will change. As you wear down your teeth, the way your jaw and face sit will start to change. This will have a noticeable affect on your appearance. As your teeth become shorter, the dimensions of your jaw, cheeks and lips will collapse, making you look older!

For the patient, it's very similar to getting a normal mouth guard. Once you come to the dental office, you will bite into an impression. The difference is that these impressions and bite measurements are much more precise than what is needed for a normal mouth guard. From here, we send the impressions away to the lab where your acrylic night guard is custom made from the measurements taken. The guard will be designed to make sure your teeth stay a certain distance apart when you sleep. In the case of snoring, it's more about creating the best angle for your jaw to be in when you lie down and go to sleep. When you next come back, the dentist will have the new night guard ready for your trial. We make sure the dimensions are correct and everything fits as it should, then you're ready to go!
