hi sushi
i don't know if your meds could be doing this or not, certain atibiotics can change the coloring of ones teeth,
not to be too personal but the older we get our teeth do get darker. also if your tooth is dying it will turn gray/brown.(i was a dental/oral surgical assistant for 20yrs). i would think maybe a trip to the dentist mite be in order.
hope this helps
take care
