I would recommend you have an exam with your local dentist. If it is simply a chipped tooth then a small bonded filling may be an option to fix the tooth. If the tooth is chipped because underlying decay has weakened the tooth then the longer you wait the worse the tooth can get and potentially cause you more pain. Fixing a problem when it is small is much easier, less traumatic and less expensive than when it gets larger! Let your dentist know you have some dental anxiety and they can do extra steps to make you comfortable.
To correct your teeth not being straight would require an orthodontic consultation with someone in your area. Most orthodontists don't charge for an initial consultation. Whitening and physical adjusting can be done to improve the color and appearance. Cosmetic crowning and/or veneers could also be an option to address these problems. I would recommend an evaluation with your dentist for more detailed information to address your specific concerns.
