<human>: since yesterday i ve had a swollen gum around just one tooth . today it is much more swollen you can barely even see the tooth. the gum is swollen that it is separating the teeth apart from each other and has a white head now. i can touch the tooth no problem without any pain, but i can barely open my mouth without pain or even close my mouth.
<bot>: Hi, Thank you for the query. White head around the teeth indicates infection of the gingival which had turned into a gingival abscess. This can be treated by cleaning the gum deep around the teeth with the scale followed by a course of antibiotic and analgesic. If it has a developed an end period lesion then you have gone for root canal treatment. Seee your dentist for the required treatment. Take care.
