Im 20 and Im not going to lie, I have poor dental hygiene. Just bc I guess I never got a habit of brushing my teeth. :(... But, I have cavities on my front teeth, and probably bottom teeth. Im kind of embarassed to even go to a dentist. So, I was just wondering, if there is any way possible all of my teeth can be fixed that need fixing? And if my smile can be whitened also? I would like to know, if they can even fill cavities on the front teeth? And if so, if there is a lasting image that you had them filled?
