<s>[INST] Hello I have a terrible toothache. Its the bottom four teeth in the middle. They seem a little loose when I touch them and they are sensitive. I have noticed over the past two days that it hurts the worst at the base of the tooth. And there seems to be some swelling on the left side of my gums at the bottom. I plan on going to the dentist Tuesday. Until then Im using Advil for the pain. Is there an dental antibiotic I can buy thats not over the counter? [/INST] Hi. Thanks for the query. Well it looks like you have deep gum Infection and as the teeth are loose also it looks like there is loss of attachment of the teeth to the underlying gums leading to periodontitis. So, my suggestion is to consult an Oral Physician and get evaluated. An X-ray should be done for further confirmation. Antibiotics for such infection is Metronidazole, Ornidazole etc. and that you can buy only after prescription. For now, you can apply antiseptic ointment like Chlorhexidine oral paste and do warm saline gargles. Apply Lidocaine gel to reduce pain. Do warm saline gargles. Hope this helps. Regards. </s>
