What are signs you need to see a dentist pronto? Bleeding, bad breath (you may need a partner to affirm this - they say a skunk doesn't smell his own odor, but then how do we verify this?), an itchy feeling in the gums, a change in gum color, or increased space between the teeth are all prime examples.

1 Expert Answer
Most Recent Answer
by Dr. Mehmet Oz

That causes them to ingest lots and lots of fluor...
