<s>[INST] The right side of my mouth is swolen well my cheek I noticed is a little fatter than the left and when I feel the back of my gum in the back of my mouth on the right side I felt pain and when I touch my cheek it s hard for me to eat on the right side and I can still laugh and talk a little but not too much, I have no clue what the issue is except for I was suppose to go for a deep cleaning at the dentist because I was told I had plac in my gums so I m not sure if that s the issue but it s been going on day 2 [/INST] Hello and welcome, normally,deep cleaning will not cause any kind of pain or swelling over gums and cheek other than sensitivity unless any trauma occurred during the procedure while using ultrasound scale and hand instruments. Have you got checked for any decay or impacted wisdom tooth in your right side?without clinical examination, we cannot decide your diagnosis and treatment plan. If you have severe gum infection, or gingivitis, i advice you to take tab.doxycycline.100 mg once a day for 3-7 days depending on severity of the problem. Please give your medical history like epilepsy, cardiac disease etc. to your dentist so that doctor can give a proper diagnosis. Hope you get well soon. </s>
