I had a problem in teeth and I need dental bonding . I need a proper consultation to plan better. Need a quick appointment.

Went to a dentist for night guards because I clench in sleep and wake up with headaches and jaw pain. But these look like retainers and my clenching has worsened after wearing these. What are these? Retainers or night guards? Wearing in upper and lower teeth, are exactly the shape of my teeth.

I have taken 3 dental Cone beam CT scan so far in the last 7 months. I have taken one ct neck last month.that makes count as 4. I have taken the third cbct dental scan and neck ct scan in December only. It's been ten days since I had the neck ct with contrast scan. I don't know if I can take another cbct scan this week? I need some dental second opinion for my pain. I asked few dentist office. They are not accepting my old cbct scan and they said they will take their own CBCT scan. So I can't give them my old scans. I have a disc which has the old scan. I don't know if I can get another cbct now? Is it safe? How many dental ct and normal CT safe in an year? Within short time. Please share the inputs doctors
