I have pericoronitis in a infected wisdom tooth in the lower left side. i have a swollen lymph node on the right side though is that possible?

Sure: The left side may be draining but the right side might be harboring something under the tissue. Get in to see the Oral Surgeon ASAP for evaluation of all the areas. You do not want to wait , especially when the lymph nodes are now involved. Explain the situation -- pain and swelling of node-- to get in ASAP. Good Luck.

An indication: When wisdom teeth cause problems, they need to come out. If you are experiencing pain, swollen gums, lymph nodes and it does not go away or if you find it difficult to open your mouth, you should see a dentist for evaluation, x-ray and wisdom teeth removal.

See dentist: See your dentist immediately. Wisdom teeth come in between 18-20 years on the average. Have the dentist take a panorex or individual x-rays of the four wisdom teeth. If infected an antibiotic may be advisable. If needed the dentist will refer you to an oral surgeon for evaluation. If the wisdom teeth are deemed impacted and need to be removed, I suggest having all four removed on one visit,

Swollen lymph node: Can indicate infection and/or inflammation on the side with the swollen node. See your Dentist to be evaluated for any of the hundreds of things that can cause the node to be reactive, things that you cannot see or evaluate. Could be from impacted wisdom tooth on your right, gum disease, cavity, fractured tooth, viral/bacterial/fungal infection, neoplasm, and so many other reasons.
