Hi,
Smile lines are also known as dynamic wrinkles that are caused by the over-activity of the muscles of facial expressions. I am not sure if the tooth extraction played a significant factor in worsening your smile lines.
Depending on the location of smile lines and the underlying facial muscles that cause it, Botox may help to reduce its appearance.
A full assessment by your preferred aesthetic doctor will be the first step to take to determine if Botox will help. Creams and laser treatments are unlikely to help in this instance.
Hope this helps!
