My 4 year old son is suffering from toothache on his upper molar tooth. What medicine can I give him?

Two important things. Give him what you would normally give him for a headache, perhaps tylenol (acetaminophen) or advil- follow recommended dosages on bottle carefully! have him avoid very cold, hot and sweet foods in the meantime. Also, have him seen by a dentist as soon as possible, preferably a pedodontist (a dentist who specializes in treating young children). Discuss cavity control and routine checkups with the dentist!
Motrin or Tylenol (acetaminophen) . As long as he is not allergic to any meds, both work fine. Make sure you see your dentist right away.

What to do if I have just had a molar tooth removed but it still feels time toothache?

Return. Please have your dentist/oral surgeon check and see why you are having toothache. Was your tooth remove to eliminate the pain you are describing? Was your tooth infected deeply--if this is the case, the nerve inside the bone still needs to heal and it will take a while. "Toothache" after tooth removal is not frequent, but your dentist may be able to tell you by knowing your specific condition. Read more...

Fistula.... I personally advise you first see a dentist to discuss your options based upon a clinical exam and x-rays. You should understand the pros and cons of each option and prognosis of Endodontic treatment followed by restorative treatment. Your General Dentist may then elect to treat you or refer you to an Endodontist (or Oral Surgeon). Read more...
