After 4 babies my teeth have been left in pretty bad shape. Have had to have 3 extractions of back molars, not noticeable to others when I talk etc. but am paranoid if I laugh etc that someone might look in and see the gaps. Also just generally don't like having gaps there. I'm left with the option of partial dentures or implants which I would prefer but are pricey. Would it be madness to raise fund for this through additional borrowing on my mortgage? Plenty of equity on the house and could afford the repayments easily.
