Sure.. the easiest way is to take a look at it in the mirror( indirect vision ) with ur dentist's help... ask ur dentist also to measure the depth of the cavity if u r so keen. Lastly, your dentist can also take an impression of your cavity in your mouth and pour a cast to show u... The last option can cost u bit more as it takes time..

Its completely depends upon your cosmetic dentist and your teeth condition. Go for componeer only when u r completely satisfied with your treatment results.
