It started yesterday when I was eating some French onion Sun chips. It's a dull pain on the tooth between the lower right canine and molar. I woke up this morning to still feel a dull pain that seems to be more annoying than painful. I'm doing some online research and just hope it's not severe. For some reason it's making me feel depressed, not clinically depressed but just a bit under the weather sort of feeling. About two years ago I had a major toothache on the lower left molar, which had to be extracted. I'm not sure if it's too late for a dental implant, seeing that over a year has elapsed and the area is sealed by gum. I'm still considering a bridge but it's not a big priority as its "hidden." If you have a tooth extracted, can the dentist have a temporary replacement right away to hide the gap?
