Dental Warranty





Akervall Technologies Inc. (“ATI”) warrants that there are no defects in the materials or workmanship of the SISU® Mouth Guard that cause damage or injury to the sound, natural teeth of the user when properly used in a supervised athletic contest or coach-supervised training session. This warranty shall extend for a period of one (1) year from the date of purchase.

ATI’s obligations in the event of a breach of this warranty shall be limited to the lesser of: (1) the actual dental expense incurred by the user; or (2) $1,094 per injured or replaced tooth, up to a maximum liability of $35,000 per incident. ATI’s obligations hereunder shall be reduced by the amount of any insurance that the user receives or may claim for the damage or injury. This warranty does not provide payment or indemnity for orthodontic treatments or preparation of a tooth to be used as an anchor for a bridge.

ATI shall have no responsibility or liability hereunder unless: (1) the mouth guard was unaltered and fitted by claimant in accordance with the printed instructions accompanying this warranty, (2) a complete written notice of the injury or damage is received by ATI within thirty (30) days after the occurrence of the injury or damage, (3) the notice of injury is substantiated by a statement of a licensed dentist providing necessary dental treatment within thirty (30) days after the date of injury or damage and a statement of a participating game official, if a supervised contest, or a supervising coach or school superintendent, if a practice session, that the mouth guard unit was in proper use at the time of injury and (4) the mouth guard unit is returned to ATI with the written notice of injury. This warranty will not apply if the mouth guard is stretched, trimmed or otherwise altered or misused.


This warranty is the exclusive warranty given by ATI and is made in lieu of all other warranties, express or implied, including but not limited to any implied warranty of merchantability or fitness for a particular purpose and any implied warranty arising out of a course of a dealing, custom, usage or trade. Except as is otherwise expressly provided herein, ATI disclaims all liability for loss, injury or damage based upon negligent design or defects in materials and workmanship for the within mouth guard. ATI shall not be liable for any special, indirect, incidental, exemplary, punitive or consequential damages.

Keep this dental warranty, disclaimer and store receipt in your records. In case of injury, mail mouth guard, store receipt, the notice of injury and accompanying statements to:

– Do not use try to fit the SISU® Mouth Guard over braces by yourself. We advise you to consult with your orthodontist first.
– Avoid situations where inhalation or swallowing of the mouth guard could occur.
– Do not stretch the material. This may thin out the material and decrease the strength of the mouth guard.
– Do not overheat the mouth guard (over 170 degree F).
– Do not clean the mouth guard in your dishwasher or washing machine, since this could lead to deforming and weakening of the material.
– Follow the instructions regarding cleaning and storage.

Protect your SISU® Mouth Guard from warm environments, such as hot dashboards in cars. When hot environments are unavoidable we suggest you keep your SISU® Mouth Guard in a container with plain water.
