<s>[INST] yesterday i used crest pro health mouthwash and started getting a tingling feeling in my mouth. when i woke up this morning my cheeks have been sore and when i eat i feeling a tingling sensation around my jawline. is there a way for me to relieve this? [/INST] Hello,  Read your query, as you have soreness in cheek and jaw this tingling sensation can be due to infection in jaw due to inflammation in gingiva or in inflammation in periodontal ligament due to deposition of food debris , not maintained proper oral hygiene,  use of tobacco containing product , or improper brushing or flossing technique. For this you can do luke warm saline gargle two - three times a day, avoid gum irritants that is tobacco containing product if you are taking, gently mas sage your gum with pulp of your finger in circular motion, you can apply ointment gum paint like stolin and take Vitamin B and C suoplements by consulting with your doctor.  Consult dentist and go for oral examination and oral prophylaxis. Hope this will help you.  Regards, Dr. Priyanka tiwari </s>
