Teeth straightening is becoming more and more popular, due to the dramatic improvements possible, short treatment times, and relative low costs (compared to smile design with cosmetic veneers).
If you are trying to move teeth, then is it likely that the lips and face may change, so is it possible to have teeth straightening and also have fuller lips (or thinner lips?)
In short, yes it is, but it is never that easy!
Increasing Lip Fullness
To increase the lip fullness, then your teeth need to be crowded or overlapped at the top, like:
In this case, you can visualise that if the teeth are straightened, then the size of the arch will increase, meaning that the front teeth will move forward, hence increasing the lip fullness.
When is this not a good idea?
There are several situations where this may not be a good idea, as you could have some unexpected results.
1. If your lips do not naturally rest together
In this case, if you move your teeth forward, then it will be even more difficult to make your lips close.
2. Your bottom jaw is relatively small.
In this case, moving your top teeth forward will increase the difference between your top and bottom teeth.
3. Your teeth are already tilted forward.
Rounding out your top teeth will only make this tooth tilt problem worse, and quite often the gums will recede if they are pushed too far.
Yes, if moving teeth will not give you the results you are after, then possibly look at using a temporary filler to increase your lip volume.
