Hello and welcome to HCM. Thank you for your query. It is comforting to know that the sexual act performed orally was on your spouse, as otherwise it would cause doubts of a sexually transmitted infection to be the cause for this. Although I would like to ask if you have had only one sexual partner, and since when have you been married? But coming down to the most likely cause, as this is commonly seen in married couples, especially the male partner, your condition could be simple inflammation of the gums also called gingivitis. Do not worry about this, it shall slowly subside. Please note that this is not considered to be a hygiene problem. The oral cavity has surroundings quite different from the vagina, which has a pH which is quite different from that of the oral cavity. I would advice some simple measures to treat your condition. Starting with regular cleansing of the mouth, especially after oral sexual contact and after every meal. You could use a mouth wash containing chlorhexidine or hydrogen peroxide. If this doesn t help much (which is in rare cases) you could also initiate a course of antibiotics (eg. metronidazole 500 mg one tablet three times a day). I am sure you will be fine in no time. In the meantime, please avoid hard food and acidic food and drinks as this can worsen the condition of your gums. I hope I have succeeded in providing the information you were looking for. Please feel free to write back to me for any further clarifications. I would gladly help you. Best wishes.
