Fixing Black Triangles Between Teeth

What they are

Small triangular gaps between teeth where the gum papilla has receded. Common after orthodontics or with age.

Treatment options

• Composite bonding: AED 400–800 per triangle, 1 visit
• Bioclear matrix: specialised composite technique, AED 800–1,500 per triangle
• Hyaluronic acid injection: temporary (6–12 months), AED 1,200–2,500
• Orthodontic tightening: closes some cases

Which is right for you

• Small triangles: bonding
• Multiple triangles: Bioclear or comprehensive reshaping
• Patient preferring non-permanent: hyaluronic acid

Prevention

• Professional cleaning every 4–6 months
• Gentle flossing technique
• Avoid aggressive toothpick use

Practical decision guide

Cosmetic dentistry is strongest when the smile plan starts with healthy teeth and gums, not with a material choice. Before committing to a visible change, confirm the diagnosis, preview the result on your own face, and understand what tooth structure will or will not be removed.

Check this first

• Gum health, cavities, bite forces, grinding history, and old restorations.
• Whether whitening, bonding, alignment, veneers, or crowns is the least-invasive option that meets the goal.
• How the proposed shade and tooth shape will look in daylight, photos, and normal conversation.

When to book sooner

• The tooth is chipped, dark after trauma, sensitive, mobile, or changing colour quickly.
• You are being offered irreversible treatment without x-rays, gum screening, photos, or a trial smile.
• You grind at night and no nightguard or bite plan is included.

Topic-specific notes

• For cosmetic work, the most protective sequence is health check, photos, smile preview, trial or mock-up where appropriate, then final treatment. Irreversible tooth preparation should not be the first step in the conversation.

Questions to ask at the appointment

• Can I see a digital preview or trial smile before irreversible preparation?
• How much enamel will be removed, and is there a lower-prep alternative?
• What happens if the restoration chips, stains, or needs replacement later?

Dubai patient note

For Dubai cosmetic treatment, ask for a written plan that separates consultation, scans, mock-up, treatment, nightguard, warranty terms, and maintenance visits. If a clinician or facility is unfamiliar, verify licensing through DHA before starting.
