Can I use dental bonding to cover my front and lower teeth instead of porcelain veneers due to the cost?

My teeth do not have much enamel left due to the medicine my mom took when she was pregnant with me. My dentist had fixed my many teeth problems. My teeth looked good, but my teeth color now is grey, bit of yellow and little transparent due to the fillings. I would like to make them whiter. I remember when I was young in China, the dentist had used dental bonding to cover my whole front and lower teeth. I wonder dentists here can do the same thing to save me some money?
