Julia Roberts is known worldwide as a beautiful woman, a great actress and having a great wide smile.
The smile is wide because she has a wide mouth, but also because her teeth are aligned and the arch is widened to show more teeth in her smile; you can actually see back to her molars.
Now we all cannot be born to look like JR but there is 1 thing we can do.
Have a great smile.
The way to do this is to straighten the teeth, push out the molars and premolars so that they show in the smile.
When you smile you can actually count more teeth being visible.
Invisalign can help achieve that perfect smile without taking over your life.
Invisalign aligners were used in the following case:

Lady patient aged 26 had 2 upper front teeth sticking out and she wanted the teeth straighten into alignment.
We noticed that she had unusual bumps on the backs of the teeth, that hit the lower teeth on biting and actually caused the overcrowding.
So we advised that the lower teeth need to be moved back, the back teeth out to allow space for the upper front teeth to be aligned.

In all it took about 12 months treatment, but the worth was worth it.
Here are a couple of videos of a similar case whereby the arch is widened to create a great smile.
