Patient's Query


My upper tooth was extracted, the one next to my wisdom tooth. Today is the sixth day, and I still get pain and sensitivity. It has gotten better, but it is still there. I have a bad taste and smell in my mouth. At the same time, after the extraction, my sinus got bad, and I had a fever for a couple of days. My sinus is still really bad, along with other sinus symptoms. I took painkillers and used the nasal spray for relief. I went back to my dentist, and they did an X-ray. It did not show any infection. He said that there are three roots, out of which two have been healed by the skin, and one is still exposed. He cleaned it and put some medication that was two days back. What should I do now? Please help.


Welcome to icliniq.com.

I read your query and understand your concern.

You have post-extraction symptoms. The total time for healing after a tooth extraction is usually five to seven days. Some people may have more prolonged symptoms but not clinically visible signs of post-extraction illness.

Are you aware of any relation of extracted maxillary root to sinus before extraction?

Was there any oro antral exposure during extraction?

Oro antral exposure refers to unnatural communication between the oral cavity and the maxillary sinus. I suggest you keep a paper in the air after opening the mouth below the extraction site and observe for flutter. If the paper flutters, there is a possibility of an oro antral fistula (exposure).

Thank you.

Patient's Query


I have always had sinus issues but nothing that I can think of. What do you think is this bad taste in my mouth? It feels like something is leaking from that area. Do you think I need antibiotics?


Welcome back to icliniq.com.

I understand your concern.

I have the following suggestions for you-

1. You must keep the area clean. Healing sites usually have lots of activity going on, so the area needs to be maintained clean.

2. Do not allow food lodgement in the area and do not consume sticky foods.

3. You must drink water more frequently.

4. Clean the extraction site after the meal.

All these measures will help to prevent bad taste.

Antibiotics are usually prescribed immediately after extraction. However, as there is no infection, antibiotics are now not required.

Thank you.
