How can I fix my ugly looking teeth ???

It is impossible to tell you what to do without seeing any photos. Schedule an appointment with a cosmetic dentist and have them do a comprehensive exam and go over your options. Have faith!  I'm sure that your smile can be removed. 

I recommend getting an evaluation for possible veneers placement. You can change the proportions of several of your front teeth so that the laterals ending being the right size in relation to your other teeth. I think Veneers would be an excellent option for you and will help improve your confidence.

yes, there is a solution, veneers are a great way to make your smile even, you can change ,she, size and even color.and the amount of veneers you need its determined when you go for a consultation, there is a need to make a smile design to tell you what is your best option,the teeth size, and gum evaluation will make you a great result.
