How the space affects your smile
Describe the gap that bothers you and the look you prefer. A single opening and several across the front teeth are planned differently. Ask how added composite would change the size and shape of each tooth.

Black Triangle Closure in Caledon
A dark gap near the gums sometimes involves more than one opinion: your dentist, perhaps a periodontist or an orthodontist. For households in Caledon, we help coordinate that conversation so you can compare options and decide on black triangle care calmly.
Bringing the opinions togetherTalk through the opinions you have heard
Who should weigh in on your gap?
Your general dentist may suggest bonding. An orthodontist might mention tooth position. A hygienist may point to the gums. Each view can be right, because a black triangle, the dark opening near the gum between two teeth, can arise from tooth shape, alignment, receding gum and bone, or several of these together.
Composite bonding is the most common cosmetic response when the teeth themselves are the main factor. Resin is shaped onto the two tooth surfaces that face each other so the space looks smaller. It cannot rebuild gum or bone, and the new contact must stay cleanable. When gum or position is the bigger issue, other care may come first.
With homes spread across Bolton and the villages of Caledon, juggling appointments for the whole family is a real consideration. We start by listening to what you have noticed, examine the gums and teeth, and help you understand which professionals, if any, should be part of the plan.
Sorting out the picture
Three areas we look at closely
Your photos help, but the reason behind a gap only shows in an exam. Share when it appeared, whether it has changed and anything other clinicians have told you about it.
Cleaning and food trapping
Point out where food catches or floss shreds, and mention any cleaning tips other clinicians have given you. We examine the contact and the side contours of the teeth. Any reshaping should leave a surface you can clean, not a ledge or a hidden pocket.
Your gum health
Bleeding, recession, tenderness or a loose tooth are worth raising even if they seem minor, since they may change the sequence of care. If gum disease is present, treating it takes priority over any decision about cosmetic closure.
Not every triangle signals a problem, and some healthy gaps are best left alone. We will separate the health findings from the appearance choices so the different opinions make sense together.
The advantage of a joined-up plan
Every step in the right order
For suitable teeth, composite carefully shaped on the facing surfaces can reduce a gap nicely. The extent depends on the tooth shapes and the gums. Complete closure may not be realistic, and planning with gum or orthodontic care in mind often gives a better long-term result.
Before treatment, ask about the planned outline, upkeep and limits. Find out whether bonding is the full plan or should follow gum treatment, orthodontic movement or a restorative change, and in what order.

One clear explanation
Ask us to summarise what bonding would change, what it would leave, and how that fits with any other advice you have received. A smaller shadow may be the right goal even if full closure would make a tooth look broad.
Care with natural enamel
Different clinicians may suggest options that ask very different things of your teeth, from adding a little resin to reshaping them for veneers or crowns. Find out how much natural enamel each route would keep, and what a future repair or replacement might involve.
Shared follow-up
Ask how the contact, gums and composite will be reviewed, and how information will be shared if a periodontist or orthodontist is involved. Know whom to call if the area becomes hard to clean.
How we coordinate care
From several opinions to one plan
Your appointment should cover appearance and oral health equally. Bring any reports or advice from other clinicians, and ask whether further input would help you decide.
Gather the history and examine
Start by walking us through past orthodontics, gum care, fillings and any advice you have already had, including letters or treatment notes if you have them. We examine the teeth and gums around the gap. Radiographs can reveal how much bone sits between the teeth and where they touch, details the eye cannot see.
Compare the options side by side
We set monitoring, gum care, bonding and orthodontic input next to one another so you can see what each would involve. If bonding fits, ask how far the gap could narrow and how the teeth would look. Confirm the estimate and upkeep.
Bond when the timing is right
Once other care is complete or not needed, the enamel is prepared, and composite is layered, shaped and hardened with a light. The contour must suit the neighbouring tooth and gumline. Ask for a pause at any point.
Review, cleaning and next steps
After polishing, the contact is tested and you are shown the right cleaning aid. We review the result with you and confirm any follow-up with us or with another clinician involved in your care.
Once the bonding is done
Simple care that keeps everyone's work intact
A smaller gap still needs daily cleaning. Follow the technique we showed you, and tell us if your usual aid starts catching or stops fitting.
Clean the contact every day
Ask which floss or interdental brush size suits the bonded spot. Use it gently rather than forcing. If floss keeps fraying in one place, arrange a check of the contact and finish.
Keep bonded edges out of harm's way
Avoid biting hard objects, pens or packaging with your front teeth. Mention any chip or sharp spot. Do not try home repairs; the fix depends on what has happened to the surface.
Keep every recommended review
Continue recall visits, gum appointments and any orthodontic retention checks. Let us know about lasting bleeding, food collecting or a space opening elsewhere. Cosmetic work does not replace monitoring of gum and bone.

Making sense of different advice
Bring any questions about your smile, your routine or advice from others. Answers should fit your situation, not a set package.
Should I get a second opinion before having a black triangle bonded?
It is always reasonable to ask. If the cause is unclear, or gum or tooth position may be involved, another view from a periodontist or orthodontist can help. We are happy to explain our findings for you to share.
Can orthodontic treatment and bonding be combined?
Sometimes. Moving teeth may reduce a space, and bonding afterward can refine the shape. Timing matters, so ask how the two would be coordinated and what retention would look like.
Will my dentist and periodontist work together on this?
With your permission, clinicians can share records and findings so the plan fits together. Ask how communication will work and who will be your main contact.
Can I book my assessment around my family's other appointments?
Yes. Let us know when you call and we will try to line up visits for household members where possible, so the trip from Caledon covers more than one need.
If different clinicians suggest different things, how do I choose?
Ask each to explain the cause they see, the goal of their suggestion and its limits. Often the advice fits together in stages. We can help you understand how the pieces relate.
Does a black triangle always mean I have gum problems?
No. Many are caused by tooth shape or position with healthy gums. An examination, sometimes with X-rays, shows whether gum or bone changes are part of it.
Visiting from Caledon
One visit to make sense of the options
Come to our Bronte Street practice with your questions and any advice you have received. We will look at your gumline, ask about cleaning and explain the options clearly, so you can decide with confidence.
Bonding is only suitable for some gaps; how your teeth are shaped and aligned and how healthy the gums are will decide it. It is not a treatment for gum disease.
