When a tooth is beyond saving, it has to be removed/extracted. Don't worry you wont feel a thing.
Tooth extraction (removal) is a dental procedure indicated in various circumstances. The most common and widely-known indication for tooth extraction is a tooth that has decayed beyond repair, or could be repaired, but at a too high cost. The other common reasons for tooth extraction include severe infections, a tooth that is blocking other teeth and stopping them from coming in, and so on. Wisdom teeth may also need to be extracted in certain circumstances.
When it comes to tooth extraction, the thing people are usually most interested in and worried about is the pain. However, in modern dentistry, tooth extraction is normally painless, thanks to local anesthetic that is administered prior to the extraction. The anesthetic stops the nerves in the area from transferring pain signals, thus preventing you from feeling pain.
Most extractions are completed within few minutes. After the extraction has been completed, it is normal to expect minor bleeding, which is easily stopped by a patch of gauze. The patch of gauze needs to be pressed against the bleeding tissue, and the bleeding should stop in a matter of minutes. Some patients may have bleeding for 12-24 hours after the extraction, but that bleeding is minimal and is considered normal.
