PRP is individual's concentrated platelets. It can only be used on the person it was extracted from.
Teeth clenching (bruxism) is often caused by your bite being incorrect. Invisalign does work for those who clench their teeth, but more attention has to be paid by the doctor. Sometimes bruxism can be improved by aligning your teeth. Botox for jaw muscles also help bruxism in certain cases. You will most likely need a night guard to protect your teeth after Invisalign. Make sure you find a qualified doctor that treats teeth, jaw joints, and muscles together.
I am sorry you are going through this. One of the symptoms of Lupus is dry mouth, which means not enough saliva to protect the teeth from cavities. It is extremely important to start a preventive protocol. Biotin dry mouth rinse, xylitol gum or mints, as well as prescription dry mouth medication/rinse/toothpaste. Your hygiene has to be perfect (electric tooth brush, floss, Waterpik). The good news is everything is possible with modern dentistry. Depending on how badly front teeth are damaged, they can be fixed with fillings, veneers, or crowns. Again, prevention is key, and fixing teeth once does not guarantee a permanent solution. Make sure you find a dentist that focuses on overall health and prevention, as well as cosmetics.
