That sounds terrible for you and your wife both. Grinding your teeth can be multifactoral. We need to determine first why you are grinding your teeth and then from there appliances and treatment can be made to correct the problem. Patients grind their teeth because of misaligned teeth, stress, anxiety and even sleep apnea. Once a diagnosis is made either a patient can do orthodontic treatment to correct the position of the teeth or have an occlusal guard fabricated or we treat the patient for sleep apnea.
Definitely get in to be evaluated by a dentist so you and your wife both can get a good nights rest.
