Send photo of your tooth

One option to accommodate and align all teeth is expansion of jaw, but it depends on what exact situation is.

Don't worry go ahead and get it removed, u will laugh at urself after extraction is it so easy

If you haven't visited a dentist yet to confirm that the tooth is an extra one, in that case,  It can be a tooth which has erupted out of alignment but actually not an extra tooth.So need to rule out that doubt first. In case it is actually an extra tooth and extraction is the best solution in your case, then I can assure you the science has developed so much that extraction is definitely possible with very little to no discomfort. You need to have faith on the clinician and mental strength of your own. It shall all work out smoothly. The injection is just a matter of exactly 5-10 seconds job, (for eg. a very young aged pt.  as less as 6 yrs also can undergo extraction when required,with not much of discomfort then definitely it is not much of a big deal) then you will not feel much discomfort.

Need to see pictures Need not to be scared, local application of anaesthesia gel before injection doesn't cause much pain Rest I can tell other options depending on position of tooth,so upload pic
