As our jaw size is small as compared to the teeth... The wisdom tooth being last to erupt in the mouth does not get proper space. So it causes pain and cheek biting. The proper treatment for the problem is to get it removed as it does not assist in eating as well.
Next Steps
visit an oral and maxillofacial surgeon for the extraction of the tooth
Health Tips
warm saline ( warm water with pinch of salt) rinses will help to relieve the pain temporarily.
