<s>[INST] I had a root canal 3 days ago on a top left molar.  I now have a sore throat and some numbness in my face , (the side that had the root canal, I do not have a lot of pain from the actual root canal, except that my tooth needs to be filed down more as when I bite down on it it hurts. [/INST] Hello, Welcome Thanks for consulting Chat Doctor, I have gone through your query, as you have undergone root canal treatment don't worry this feeling of numbness and tooth hurts on bite is normal after RCT treatment. You will do is warm saline gargle two - three times a day One Capsule vitamin B complex once daily for 7 days Avoid eating from side of RCT Treated tooth for at least 15 days after 15 days you feel pain then consult your dental surgeon again and go for examination of tooth. Hope this will help you. </s>
