2) As I said, the 2 year duration makes me skeptical it's a wart. But in
any case, it will have no impact on safe pregnancy
, labor, delivery, or breast feeding. Even genital HPV infections rarely have such effects.
Bottom line: I urge you to discuss the situation again with the oral surgeon, telling him or her what I said about the infrequency of oral warts and rarity of such prolonged warts. If s/he recommends a biopsy to confirm the diagnosis, I recommend you do it.
