Our toughest and most durable night guard!

The 3mm thick soft/hard night guard is the guard to purchase for those who are heavily grinding or clenching  their teeth during sleep and for those who want maximum protection. Not only will it protect your teeth but will also disengage the condyle area of the lower jaw from the upper jaw, taking pressure off the joint and giving relief to those suffering with jaw ache or headaches when they wake in the morning.


The hard outer material is extremely tough and durable against grinding while the soft inner material provides a layer of comfort for the wearer. The guard is perfectly adapted to you uniquely as we provide a home impression kit to acquire an accurate mold of your teeth. Just like at the dentist but without the huge cost!


Please note the home impression kit for our 3mm night guard contains impression trays for the upper and lower teeth. This is so we can imprint your lower teeth into the bite surface of the guard to achieve a balanced bite platform for your teeth. Some other direct to customer companies do not provide the lower jaw impression and this can end up with a guard design that props the jaw open due to the rear molars making contact with the guard surface before the other teeth. Purchase from us and experience the difference of a guard made with proper care and consideration of your teeth's bite relationship.


Unlike some other night guard companies our guards are designed to cover all the teeth on your chosen side (upper or lower guard) unless you request otherwise. Some other companies only cover up to the first molar and this can put your teeth at risk of super-eruption due to the tooth being unopposed to the occluding teeth. This can lead to an uneven bite or misaligned teeth. 


Need a spare guard?

Purchase two guards at the same time and save 50% on the second guard. Please note that only one impression kit will be sent for both guards.


Please ensure both upper and lower impressions are completed and returned, regardless of night guard side choice, to avoid any delays or extra costs incurred for an incorrectly fitting device. 


Upper or Lower?

90% of customers choose the upper night guard option and this what we would normally recommend as there is less chance of the tongue dislodging the guard during sleep and the larger upper teeth usually provide better retention for the guard to stay in place. If however you have had some dental work on the upper teeth or would prefer the feel of a lower guard then we provide that as an option too.
