This is often associated with a cracked or fractured tooth. However it may also occur with recently restored teeth. If the tooth is cracked or fractured, the tooth will need to be rebuilt. This may be a restoration that is a filling or a crown .
If the tooth was recently restored, the surface of the new restoration may need to be adjusted. Sometimes even the slightest difference in the bite will create a stress point that can be easily adjusted at the dental office.
This usually indicates a serious dental problem. Prescribed medication can temporarily relieve the pain but you must see your dentist.
Swelling seen in the mouth or externally (face, cheek, neck) usually means there is an infection. Prescription medication will help alleviate the pain. To resolve the problem you will need to see the dentist to treat the tooth that has the infection. Even if the medication has taken the pain away that does not mean that the infection has disappeared. Without treatment usually the pain returns.

Every so often something gets stuck between your teeth. Even after flossing and flossing, you can still feel something stuck. The smallest pieces can feel very irritating.

Your dentist will have proper tools that will safely open up the contacts between your teeth and remove the foreign objects.
Use your teeth only for food not as a bottle opener.
