Random Bird catches Sketchy worm (>?_

I went to a new dentist yesterday and he said simply "you have a clean mouth" no need for overreact. Whearas the other dentist said, YOU WIll die a slow horrible roasting death for evil doers in the depths of hades if you don't FLOSS you vile slime_bucket! who should I beleive and what are their MOTIVES (operandi) for telling me such differentiating stories.
