Sometimes a group photo is the first place a small gap near the gums stands out. Book a black triangle closure visit in Milton to learn why the space is there and which options could soften it while keeping it easy to clean.
Plenty of people spot a black triangle in a close-up photo long before they notice it in the mirror. It is the small, dark wedge that can sit between two teeth, just below where they touch and above the gum. The name only describes the look. Tooth shape, tooth position and the gum and bone support underneath all help explain it.
When the space suits it, tooth-coloured composite can be added to the sides of the neighbouring teeth so the opening looks smaller. This reshapes enamel surfaces only. Gum tissue that has receded and bone that has been lost stay as they are, and a good outcome still needs a sensible contact point and a surface you can clean.
For people here in Milton, the first visit starts with your own story. The gap may have been there for years, shown up once braces came off, or arrived alongside gums that seem different. Our job is to sort out what needs a health check first and only then talk about cosmetic choices.
Your phone camera can show the gap, yet only an exam explains it. Let us know when you first saw it, whether it seems to be growing, and anything else your mouth has been telling you.
Point to the exact space that bothers you and describe the change you would like. One narrow gap and a row of them across your smile are planned differently. It is worth asking how added material might alter how wide and how long each tooth appears.
Show where bits of food lodge and say whether flossing there is awkward or sore. A careful plan looks at how the teeth meet and how their sides are shaped, not just at hiding the dark area. Nobody wants a new ledge that traps more than before.
Mention bleeding, receding gums, tenderness or a tooth that feels loose. Any of these can change what comes first. When gum disease is part of the picture, getting it under control takes priority over deciding whether cosmetic closure makes sense.
A visible triangle does not always signal a problem, and a healthy one does not always need fixing. Ask us to separate the findings that affect your oral health from the choices that are mainly about looks.
Some spaces can be made smaller by building composite onto the facing surfaces of the two teeth. How much can change depends on the shapes you start with and the condition of your gums. Closing a gap entirely is not always realistic, and sometimes it would not look right.
Before you say yes, talk through the outline the teeth would have, how the bonding would be maintained and where its limits lie. You should also know whether this is a single cosmetic fix or one piece of broader gum, restorative or orthodontic care.

Ask your dentist to name what the bonding will alter and what it will leave alone. That keeps expectations concrete. A gap that looks noticeably smaller can be a good result even if closing it fully would leave one tooth looking oversized.
Find out how the surfaces would be prepared and whether material is added, removed or both. Cosmetic options do not all involve the same amount of preparation. It also helps to ask what repairing or replacing the bonding might involve in later years.
How the teeth look straight after treatment is only part of the story. Ask how the contact, your gums and the composite itself will be checked at future visits, and who to call if cleaning that spot becomes a struggle.
Your appointment should leave room to talk about both appearance and health. Feel free to ask which records are needed and whether a specialist's opinion would help you decide.
Share any past braces, gum treatment, fillings or crowns, and roughly when the gap appeared. The dentist examines the teeth and gums around it. X-rays or other records may be needed to judge bone support and how the teeth meet, since the visible gap alone does not tell the whole story.
Discuss whether watching it, gum care, bonding or an orthodontic opinion fits what was found. If bonding is suggested, ask how each tooth's shape would change and how much smaller the gap can sensibly get. Confirm the estimate and what upkeep will look like.
Once you agree to bonding, the tooth surfaces are prepared and resin is applied, sculpted and set with a curing light. The work has to respect the neighbouring tooth and the gum edge. Let the team know any time you want something explained or need a short break.
The bonding is smoothed and polished, then checked. Ask for a hands-on demonstration of cleaning between the treated teeth. Go over any gap that remains, the new shape and your follow-up schedule so you know exactly what changed.
A smaller-looking gap still needs daily attention. Stick with the method you were shown, and tell us if your usual floss or brush no longer slides through comfortably.
Ask which floss or interdental brush, and which size, fits the treated spot. Use it gently instead of forcing it, and do not skip that area. If floss keeps fraying or snagging, book a check so the contact and surface can be looked at.
Skip chewing on pens or ice, and keep your front teeth away from packaging. Tell us about a rough edge, a chip or a change in shape. Please do not try to sand or glue it at home, because the right repair depends on how the bonding looks.
Carry on with the recall and gum appointments suggested for you. Report ongoing bleeding, food packing in or a gap that appears somewhere new. Cosmetic bonding does not replace the need to keep an eye on the tissues holding your teeth in place.

Bring whatever is on your mind about your smile and your cleaning routine. Answers should fit your particular gap, not a one-size cosmetic package.
Come to our Bronte Street practice to talk about your gumline, any trouble cleaning between your teeth and the options that might suit. We will walk you through what we find before you make any decision about treatment.
Whether bonding suits you depends on tooth shape, position and gum health. Cosmetic bonding is not a treatment for active gum disease.
