I Have a Really Large Smile and Raised Smile Lines, Can This Be Fixed With Botox/Fillers?

Fillers can be used to soften lines and wrinkles in the face. As far as Botox, you need to be careful as the mouth is tricky area to use Botox in. You could end up with a crooked smile. It would be best to set up a consultation with a board certified facial plastic surgeon.

If it's the depth or prominence of your smile lines that is bothering you, treating those areas with a filler can help to soften their appearance.  Botox can be used selectively to change the appearance of your smile, but I do not think it would address your concerns.  

Without at least viewing photo's of what exactly you are referring to, it's difficult to answer your question. You should consider posting photo's at rest, and while smiling for better assessment.

Smile lines can be from many different things. Usually Botox is not used to chane your smile it may require fillers. But an exam is key.

MPT, It is hard to know exactly what you mean without a photo. A "gummy" smile which show too much gums and teeth can be fixed with Botox/Dysport/Xeomin. A smile that is so wide that it goes from ear to ear is different as stopping that would stop some movement that you want. However, long lips can be made less obvious by adding volume to the central portion and not the lateral parts. I have lips like that and that is what I  do. If you can send a photo that would really help.
