I have composite fillings made with composite (Epoxy ?) resin which is exposed to an ultra violet laser at each stage of the filling process, and the Dentist uses an orange filter plate to protect his eyes and those of his assistant. Because the filling is hardened as it progresses it can be used very soon afterwards, although a period is recommended before usual eating. More expensive than amalgam filling, it is very effective and durable. I also have amalgam fillings, and am very pleased indeed with my Dentist's work. Individual teeth can be inserted directly into blank gums at some specialist clinics elsewhere, but the cost is very high - about £1,500 per tooth!
