<s>[INST] hi i have been expericencing really bad pains in my mouth on teeth number 7 and 8 i had a partial root canal done on both of them and i have been put on amoxicillan for any infection i believe i have an abesse i feel a metal taste in my mouth i can still feel pain on the teeth when tapped on and i feel like a headache and upset stomach what could be my next step? [/INST] Hi, Thanks for asking the query, Pain in the teeth is because of incompletely done Root Canal treatment. Stomach upset is because of use of antibiotics, consult your Dentist and get the antibiotic changed .  Antibiotics and analgesic will give temporary relief. Get the abscess Chat Doctor. Unless the tooth is devitalized, disinfected and sealed to the apex you may experience pain and infection. Hope this helps out . Regards..... </s>
