Teeth that appear unusually small often have normal physical dimensions hidden under excess tissue. A clinical evaluation distinguishes between anatomical tooth height and soft tissue coverage before considering any aesthetic procedure.
A thorough assessment helps patients explore Why Does My Smile Show So Much Gum: Causes and Assessment to understand whether gingival enlargement or tooth coverage causes their smile concerns.
True Tooth Size Versus Covered Crowns

Teeth that look unusually short do not always lack physical height. In many individuals, the anatomical crown has developed to a normal size but remains hidden beneath excess gingival tissue1.
Altered Passive Eruption

During normal dental development, the gum tissue recedes to reveal the enamel crown. When this physiological process fails to complete, altered passive eruption occurs1. The excess gingiva continues to overlap the enamel, leaving a noticeably shorter clinical crown exposed1. In a typical maxillary central incisor, normal crown height measures 10 to 12 mm, but altered passive eruption can reduce this exposed height by 2 to 3 mm or more1.
Clinical Periodontal Examination
A detailed clinical evaluation determines whether the full anatomical crown is present beneath the gum margin1. During an intraoral examination, specific diagnostic steps identify whether soft tissue coverage is the primary cause of a gummy smile:
Gum Inflammation and Medication Effects

Swollen, prominent, or enlarged gums often alter the appearance of a smile. In clinical evaluations, excessive gum display can stem from gingival enlargement, localized tissue inflammation, or altered passive eruption34. Plaque buildup and inadequate oral hygiene commonly trigger localized inflammation and tissue hypertrophy5.
Prescription medications represent another recognized contributor to gingival enlargement4. Certain pharmaceutical classes can prompt noticeable tissue overgrowth:
- Calcium channel blockers, which also carry theoretical interactions with botulinum toxin6
- Immunosuppressants
Before considering aesthetic interventions such as Botox to manage gum visibility, underlying dental and periodontal factors must be thoroughly examined. When enlarged gum tissue relates to ongoing pharmacotherapy, patients must never stop, pause, or alter their prescribed medications without direct guidance from their treating physician. Any adjustment to systemic medication regimens requires coordinated medical supervision to safeguard overall health.
Periodontal Care and Crown Lengthening

When excess gum tissue obscures normal tooth structure, a periodontal assessment or surgical crown lengthening may be recommended7. In an intraoral examination, central incisors normally display an exposed crown height of 10 to 12 mm; measurements below this, combined with excessive tissue coverage or margins extending beyond 2 mm from the cementoenamel junction, can point to altered passive eruption1.
Crown lengthening reshapes the gumline to expose healthy enamel and establish natural tooth-to-gum proportions7. The specific surgical approach depends on individual anatomy:
- A simple gingivectomy may be sufficient when excess tissue is limited to the soft gingiva and adequate biological width exists89.
- If the bone crest approximates the cementoenamel junction, an apically repositioned flap with osseous recontouring is required so tissue does not re-establish coronal to the bone crest8910.
- When hyperactive lip movement also contributes to excessive gingival display, crown lengthening can be evaluated alongside lip repositioning or non-surgical options like Botox411.
Dr. Purohit’s note: Dr. Vishal Purohit provides non-surgical Botox treatments after dental causes are evaluated. His practice offers no laser treatments of any kind.
Limits of Injectable Muscle Relaxation

Botox targets muscle mobility when excessive upper lip movement contributes to gum visibility112. However, injectable treatment acts only on soft tissue dynamics. It cannot remove excess gingival coverage, reshape underlying alveolar bone, or resolve active oral health conditions410.
When excessive gingival display stems from dental or structural factors, muscle relaxation cannot correct the anatomical source:
Altered Passive Eruption
Delayed tissue recession leaves short clinical crowns and excess gum tissue over enamel, requiring surgical exposure or bone recontouring rather than neurotoxin injections1410.
Attempting cosmetic muscle relaxation over unaddressed dental conditions creates poor aesthetic results and risks leaving underlying oral disease unmanaged13. Dr. Vishal Purohit evaluates facial aesthetics with an emphasis on safe, evidence-grounded care, ensuring primary dental and periodontal causes are properly addressed first to support safe and durable oral health.
Primary Dental Consultation and Choices

A formal dental or periodontal assessment should precede any aesthetic injectable consideration. Evaluating smile aesthetics requires an accurate diagnosis based on the static and active relationships among the lips, teeth, and periodontium15. When dentofacial structures or underlying tissues contribute to gum display, interdisciplinary coordination between dental specialists and facial surgeons ensures that each contributing factor is recognized15.
Shared decision-making forms an essential part of the consultation process, engaging patients to weigh options when multiple reasonable pathways exist16. Following an evaluation, patients may select from several paths:
- Address the tissue through targeted dental or periodontal intervention.
- Pursue targeted dental hygiene and routine maintenance.
- Retain their natural smile without undergoing clinical procedures.
Choosing no treatment remains a valid option for anyone evaluating aesthetic changes. Specific treatment pathways, procedural suitability, and product selections are not predetermined; each plan is decided at the consultation. Dr. Vishal Purohit conducts individual clinical examinations to evaluate facial anatomy before discussing potential non-surgical approaches.
