High smile teeth
A high smile line shows more gum above the upper front teeth and may reflect tooth length, lip movement, gum position, or jaw structure.
The short answer
A high smile line is a smile display pattern in which the upper lip exposes a noticeable band of gingiva above the front teeth.
What is the direct answer?
What does this question mean?
The visible balance depends on incisor crown height, gingival margin position, upper-lip length and movement, tooth wear, and the vertical position of the upper jaw. The same appearance can therefore have different anatomical causes.
What can you do next?
A dentist may photograph the smile at rest and in motion, measure tooth and gum proportions, assess enamel and gum health, and use digital planning. Options can include orthodontics, periodontal crown lengthening, restorative reshaping, or selected lip or jaw procedures, depending on the cause.
When should you seek dental care?
Seek an assessment before cutting gum tissue or placing veneers, especially if teeth are short from wear or gums are inflamed. Care is more urgent if the display is accompanied by pain, swelling, bleeding, or a changing bite.
What should you ask the dentist?
Ask which structure creates the high gum display and whether treatment changes gum, tooth, lip, or jaw anatomy. Ask how much healthy enamel and gum tissue would remain and whether orthodontic or periodontal assessment is needed.
Frequently asked questions
Could this be caused by something other than the obvious explanation?
Yes. The examination should separate local irritation from tooth disease, infection, medication effects, and conditions outside the mouth.
What happens at the dental visit?
The clinician reviews the history, examines the tissues and teeth, and uses targeted measurements or imaging when those findings are needed.
