hello and welcome to hcm forum,
according to the dental and medical history provided by you it seems that you have some wart
like lesions in your mouth, i cannot assure you if it is from your partner, until a biopsy
can also cause such projections, therefore i advise you to quite smoking and visit a specialist(oral pathologist) to rule out the cause,
you need not worry, your dentist
will plan a treatment for you in case you need it.
i wish you good health.
