<s>[INST] I have a crown that I had done in Mexico. The dentist here in NM x-rayed the tooth and it shows substantial decay. I have an appointment for June 21 to remove the crown to get rid of the decay and recrown the tooth. I'm not sure this is related but in May I had a slight headache for two weeks, and now I have been experiencing slight vertigo and dizziness in the last two weeks, which seems to be getting worse. I have a doctors appt tomorrow, but could my tooth be the cause even though there is no pain or seemingly no infection that I can tell? [/INST] Hi,Thanks for posting the query,   This could be in relation to the decay you have developed in the infected tooth, since you have appointment with the Dentist tomorrow till then you can take tab almox C BD, tab tab nimi BD for 3-5 days and continue with the medications after consulting your Dentist.Take care! </s>
