Enamel loss

[dragonDan]

Any dentists can offer some advice? I have enamel loss on my front teeth and they are embarrassingly yellow.
Is there any way I can whiten without veneers or composite ?

No. The yellow is the layer under the enamel, the dentine. You will need it covered over with a layer of matching filling. Veneers are expensive and fall off, so I'd try to avoid them.
