I think you are talking about one of your premolars. I have extracted few of them before. The main aspect of this would be getting proper and profound anesthesia. The first couple of injection should sting for less than a second, but after that you should have no problems. After the extractions you will be a little sore and tender in the area for a few days, you should reach the peak in 2-3 days. Soft foods for a few days, be gentle brushing the area. The main thing is no smoking, straws, or strenous activity for about 4 days, anthing that creates a negative pressure in your mouth; you don't want a dry socket. I don't think you'll experience any problems.

i know it's easy for me to say. Good luck, you'll be allright.
