Dentist tips

I have a dentist appointment early next month and I'm trying to figure out the best way to handle it. I've tried the redimask thing, but wearing that plus my n95 causes me to have anxiety attacks due to claustrophobia... so I can't do that. My dentist does use hepa filters in each room and they wear at least surgical masks when working on a patient and I do have a personal air purifier I could bring with me...

My plan is to wear my n95 until they need to clean my teeth and put it back on as soon as possible afterward. I'll do mouthwash + nose spray before and after my appointment. My appointment is also the first of the morning. My question is, do I need to isolate/quarantine from my significant other after my appointment if I do all of these things? Or does that seem like overkill?
