(:1f539:) Does Walmart sell GLYDE Sheer oral dental dams?
(:1f539:) Can you use saran (plastic) wrap or glad wrap as an oral dental dam?
NO. It is not recommended to use plastic wrap for protection during oral sex as there are no studies to prove it offers an effective barrier. Plastic wrap was never intended for this purpose. Only proven dental oral dams are recommended.
(:1f539:) Why are dental dams so expensive?
It is impossible to put a price on protecting yourself against any STD (STI). The expense however is a result of the stringent processes and quality materials used, along with the careful preparation that each oral dental dam faces as compared to say condoms and foils that can be mass produced by machines.
