Bioclear is a minimally invasive cosmetic treatment that closes the dark gaps, or black triangles, between your teeth. Using a clear matrix and warmed composite, we seamlessly fill open gingival embrasures for a fuller, healthier-looking smile.
Fills the dark gaps between teeth for a fuller smile.
A conservative method that preserves natural tooth.
Smooth composite shaped to look completely natural.
Healthier contours that are easier to keep clean.
Black triangles, clinically known as open gingival embrasures, are the small dark gaps that appear at the gumline between two teeth. They form when the triangular wedge of gum tissue, called the papilla, no longer fully fills the space where the teeth meet.
These interdental black triangles are mostly a cosmetic concern, but the gum gaps between teeth can also trap food and plaque. At Mint Dental Care we treat them with Bioclear, a conservative, drill-free approach that restores a continuous, natural smile line.
Black triangles almost always come down to one thing: the gum papilla no longer filling the space between two teeth. Several factors can drive that papilla loss.
Receding gums pull the papilla downward, opening a dark triangle near the gumline.
Triangular or tapered teeth meet only at the tips, leaving a wider gap below.
Periodontal disease destroys the supporting bone that holds the papilla up.
Straightened or crowded teeth can reveal black triangles once they shift into line.
The Bioclear Method is a modern, minimally invasive cosmetic treatment that wraps tooth-coloured composite around the tooth to close gaps and rebuild a healthy contour. It relies on the Bioclear matrix system and composite injection molding, no drilling and no enamel removal.
All three can improve your smile, but only one is purpose-built to close interdental black triangles conservatively. Here's how they compare as a black triangle fix.
Our cosmetic dentists will examine your gums and teeth, confirm whether Bioclear is the right black triangle fix for you, and explain exactly what to expect, so you can move forward with confidence.

Bioclear is built to last. Because the warmed composite is injection-molded into one continuous, void-free piece, it's far stronger than hand-layered bonding, most patients enjoy their results for 7 to 10 years or more with good care.
The smooth, polished surface resists staining and plaque, which helps the black triangle fix stay looking fresh. Simple maintenance keeps your smile in top condition for years.
No, Bioclear is one of the most comfortable cosmetic treatments we offer. As a truly minimally invasive cosmetic treatment, it works with your natural teeth rather than against them.
Healthy enamel stays intact, so there's no grinding and no sensitivity afterwards.
Because nothing is cut, most cases need no injections or local anaesthetic at all.
The Bioclear matrix slides softly below the gumline without trauma to the tissue.
Most visits are short with no downtime, you can return to normal life right away.
The cost of Bioclear depends on how many black triangles need closing and the complexity of each tooth. Because it's a no-drill, minimally invasive cosmetic treatment, it's often more affordable than veneers, and everything is explained in full at your initial consultation, with no hidden fees.

I recently had a tooth filling done, and Dr. Zee was extremely professional throughout the entire experience. He was a great listener and provided clear, helpful advice. The procedure itself was smooth, quick, and much easier than I expected.
After years of dealing with on/off pain on my tooth (RCT) I finally found relief thanks to Dr. Neha Singh from Mint Dental Clinic. From the moment I walked into her clinic, I felt a sense of calm. Her gentle approach and extensive knowledge put me at ease.
I had an amazing experience with Dr Neha and her associate nurse Mrs Nable! From the moment I walked in, the meet and greet staff were welcoming and professional. Dr Neha took the time to explain everything clearly and made sure I was comfortable throughout.

I had a great experience at Mint Dental Care with Dr. Zeeshanali and Dr. Neha. From the beginning, they both took the time to explain every step of the treatment clearly and made sure I felt comfortable throughout the entire process.
I recently went in for a general check-up, cleaning, and X-ray, and I had such a great experience. I’m usually very anxious about dental visits because I’ve had some really bad experiences in Dubai, but Dr. Zeeshan completely changed that for me.
The best dentist I’ve been to. I’ve been visiting for over two years and they are very helpful and professional. Dr Zeeshanali has been amazing especially with care before my wedding. Nurse Jithu is so lovely and professional as well.
I am someone who is genuinely frightened of the dentist, so booking this appointment took a lot of courage for me. From the moment I met Dr Neha, she immediately made me feel calm and reassured.
Absolutely outstanding experience at Mint Dental Clinic. Dr Neha performed my root canal so smoothly and painlessly that I was genuinely amazed, her skill and calm approach are exceptional. Nurse Mary was incredibly kind and reassuring throughout.

I had an excellent experience with Dr. Zeeshanali for my root canal treatment. From start to finish, the entire process was completely pain-free, which honestly surprised me in the best way.
Most black triangle cases are completed in a single appointment. If several teeth or larger gum gaps are involved, we may split it across two visits for the best finish.
Yes. The composite is fully cured before you leave, so you can eat and drink straight away with no downtime. We simply suggest going easy on staining drinks like coffee and red wine for the first day or two.
Brush twice a day as usual and floss gently, the closed contour actually makes flossing easier and keeps food out of the old gum gaps between teeth. Regular hygiene visits keep the polish looking fresh.
Yes. We carefully shade-match the composite to your surrounding teeth, then sculpt and polish it so the repair blends in seamlessly. Once finished, the closed triangle is virtually invisible.
It's highly conservative. Because no enamel is removed, the composite can usually be adjusted, refreshed or removed without harming your natural tooth, unlike veneers, which are permanent.
Most people with interdental black triangles and healthy gums are excellent candidates. At your consultation, Dr. Reji and our cosmetic team will check your gums and confirm whether Bioclear is right for you.
