    Spoke with Alexandra and she was very helpful and recommend that a ask for some extra putty!!

  2. (verified owner):

    So glad they started offering the 3mm night guard. I grind so badly that my teeth were wearing through the 2mm hard guard. I’ve had this one for 8 months now and so far so good!
