<s>[INST] Hello. I really can not explain what is happening internally with me.  I just feel that something is going on.  I do have some dental issues and I have been taking an antibotic for the infection. however, I get this taste or sensitive smell?  I really dont know how to explain. [/INST] Hello, Welcome Thanks for consulting Chat Doctor, I have gone through your query, you have smell in your mouth as you are taking medication don't worry, you consult dentist and go for oral examination and oral prophylaxis. As you are taking medication also sometime it happens due to taking antibiotics there is decapitation of papillae.  Do warm saline gargle two - three times a day Do chlorhexidine mouthwash twice daily Use tongue cleaner to clean your tongue. Hope this will help you. </s>
