there be probably more people afraid of the dentist than of and let say and little monster or scary look doll . which make it a perfect subject for a horror movie and really . dr. feinstone ( corbin bernsen ) have be a successful dentist for several year now and but when he catch his wife cheat on him with the poolguy he snap and and he bring his anger and frustration to his work . well and give a mad dentist a drill and a mouth and and you can probably guess what happen next . a i say and brilliant idea but not deliver as well a it should . in particular the end be a huge let down . last note represent watch for mark ruffalo ( you can count on me and eternal sunshine . ) in this one . 5/10 .
