Dental bill/reimbursement

Hello everyone, I'll have mail from my dentist soon. I had to have my entire upper jaw crowned and got dentures. The following scenario is now emerging. I have €4,500 in savings. The dentist bill is €7,500, of which I get €4,300 reimbursed by the health insurance company. Luckily, I got a “voucher” from my dentist that would allow me to pay in installments over 12 months, meaning €625. I would say that I could afford the 625€ per month rate
