[|Human|] Hello, I have a tooache. I think it is caused by a decaying tooth in the final position of upper row. I have taken Advil for 3 days (today is the third day). But the pain comes back every 5 hours. I cant see a dentist today since it is holiday in Canada now. What else can I do to relieve the pain at least until I see a dentist tomorrow? Is it ok when I take advil for 3 days, which means that I took 4 tablets totally? When the pain is still here, can the decaying tooth be removed? I also wash my mouth by water with salt (salt is used for cooking). Is it dangerous for the pain? Thanks.
[|AI|]  Thanks for your query, I have gone through your query. The pain is because of the root tip infection in the tooth(acute apical periodontitis). You need to get a radiograph to rule out the tooth infection. If the tooth has sufficient structure left(>60%), then it can be restored with RCT and crown. If I am your treating doctor, I would have prescribed a course of antibiotics like amoxicillin 500 mg and metronidazole 400 mg TID for 5 days (if you are not allergic). You can continue taking Advil three times daily till you consult the oral physician. You can do saline gargling. I hope my answer will help you, take care.
