My missus wanted hers done also but id be f**ked if i were paying what our dentist quoted. So we shopped around and found there are some good deals to be had if you wanna do it yourself.
In the end it only cost me £8.95 for the gear from homebase (bit pricey as its posher than B&Q). Im happy, shes happy so its a winner. Also shut her up for a few hours while it dried - bonus.
Gotta be one of the funniest things i've read on here ha ha ha quality mate
