Good day
Judging from your photo, you clearly have what we sometimes refer to as a "gummy" smile, which means that you show a lot of gingiva when smiling. Your lips look normal, but you also seem to maybe have a deep bite. This is where your upper incisors overlap your lower incisors, more than normal. This could lead to future problems, since a deep bite can lead to enamel loss at the back of your upper incisors, resulting in sensitivity and other problems.
I would go for a full consult with a dentist, who can evaluate it more clearly in person and then refer you to an orthodontist if this needs correcting.
You can also undergo a procedure called crown lengthening in your maxilla, which might increase the amount of tooth structure shown and decrease the amount of gingiva. This is all dependent on a more fulin depth examination though.
