Does anyone know any good home remedies for a toothache since the dentist is not open right now?

Some. First take some ibuprofen. Then try cold or hot liquids as one or the other may take away the pain (may make it worse too!). The try some otc tooth ache drops on a cotton ball and place it over the tooth. You may have to put a drop or two directly onto the tooth. Hot packs, cold pack to the outside. You decide. See th dentist as soon as possible.
Advil & Tylenol (acetaminophen) Until the toothache is treated, your best bet for controlling the pain is taking advil (ibuprofen is the generic name) and tylenol (acetaminophen) (acetominophen). For an adult, take 3 advil, then 3 hours later take 2 extra strength tylenol (acetaminophen), then 3 hours later 3 advil, then 3 hours later 2 tylenol (acetaminophen), and keep repeating that regimen. You can do this safely for up to 10 days.
Not really. I'm sure this is a problem that didn't just start, so you should have seen a dentist before this for rx. Until you can get to dentist, take otc analgesics (ibuprofen is best) /exactly as directed on the package with food or liquid. Use cold compresses. This should take the edge off (won't cure the infected tooth) until you see the dentist for definitive treatment.
Tylenol, (acetaminophen) Advil. Tylenol (acetaminophen) and other otc meds will help, but you should see your dentist because a toothache is a symptom of a deeper problem. Make sure you get an exam and x-ray to rule out an infection or broken tooth. You cal alternate 200 mg Ibuprofen with 2 extra strength tylenol (acetaminophen) for moderate pain control.
Ibuprofen. Otc Ibuprofen is a very good pain reliever for teeth pain. Please consult your dentist or medical doctor to ensure Ibuprofen is ok for you to take.
