Sir if you are satisfied with the extra tooth, you may not go ahead with extraction. It totally depends on your wish. If the space is available then the dentist may place a crown or veneer on it and try to make it look like a normal tooth. Or else extraction is the last option left. And it's normal to feel scared but you can relax yourself and ask the dentist to minimise the pain as much as particle, though there is almost no pain. Don't worry and be relax. Take care.
Next Steps
May think of no extraction if satisfied with looks.
May go for Veneer or Crowns
