<human>: Hello, Couple of months ago, a dentist did a filling for me. It was some kind of small tube, after filling it looks exactly like a part of tooth , same color. Now I moved to Italy, and here the temperature is too cold right now. I have this bad tooth / jaw ache. what could be the reason ? Temperature ? Also, I never had tooth ache until the day I started using Sensodyne tooth paste! a serious mistake! My private insurance doesnt cover dental problems. Are there any home remedies apart from warm water + salt ? Some thing that can help me for a few months.
<bot>: Hello and welcome to Chat Doctor, toothache indicates bacterial decay or infection in the tooth that involves the exposed tooth nerve tissues.  Such infected tooth needs to be treated by a root canal procedure, so please consider getting the treatment done by consulting a dentist.  You may need an X RAY examination done for your teeth to confirm the spread of infection and the surrounding structures involved.  I would suggest you to start with antibiotic Augmenting 625 mg along with analgesics like diclofenac two times daily for 3 to 5 days.  Medications will help in subsiding the symptoms. I hope this helps, take care.
