Rav Schwartz ZT"L holds that mouthwash and toothpaste do not require hashgachah, but it is preferred to use a kosher variety if available. This site (and our OTC medicine list on crcweb.org) lists certain brands that are known to be acceptable for those who want to find varieties which do not contain non-kosher ingredients.

Vitamins
cRc policy is that vitamins are generally treated as food supplements which require hashgachah even if they are in pill form. If a doctor recommends a specific vitamin which is not certified, please review your situation with your doctor and Rabbi. An exception is that multivitamins and prenatal multivitamins which are in tablet form are acceptable even if they are not kosher-certified. This exception does not apply to [a] Pesach, [b] similar products in chewable, liquid, or gelcap, or [c] tablets with just one or two vitamins in them.
