Your teeth are finally straight, yet small dark gaps appeared near the gums once the braces or aligners finished. From Burlington, come and find out why that happens and whether composite reshaping can soften the spaces while your retainer still fits.
It can feel unfair. After months of treatment the teeth line up beautifully, and then you notice little dark triangles near the gums. Crowded teeth sometimes overlap in a way that hides their true shape; once they are untangled, a narrow neck or a gap above the contact point can become visible. Gum and bone levels may also play a part.
Composite bonding is one way to respond when the tooth shape is the main reason. Resin is added to the sides of the neighbouring teeth to make the opening smaller. That changes the teeth, not the tissue: gum that has receded or bone that is missing is not replaced. The result also has to keep a cleanable contact.
For people in Burlington who have just finished orthodontics, we start by hearing about your treatment and how the space developed. We examine the gums, check how your retainer fits and talk about any changes you have noticed before cosmetic options come into it.
Photos from before and after your orthodontics can be helpful, but they cannot replace an examination. Tell us when the space appeared, whether it seems to be changing and anything else you have felt.
Point out which triangle draws your attention and what you would like to change. A single opening between the central teeth may be handled differently from several along the arch. Ask how added composite might affect tooth width now that everything is aligned.
Mention spots where food lodges or floss snags. The dentist checks how the teeth now touch and how their sides are shaped. Any reshaping must leave a smooth surface you can clean, not a shelf where debris gathers.
Tell us about bleeding, recession, tenderness or a tooth that feels mobile. Teeth that have recently moved can need time to settle, and any sign of gum disease should be treated before cosmetic closure is considered.
Plenty of post-orthodontic triangles are simply the result of tooth shape and are perfectly healthy. We will be clear about what matters for your oral health and what is a choice about appearance.
Composite carefully shaped on the adjoining surfaces can make some triangles much less obvious. How far that goes depends on the tooth outline and the gums. Complete closure is not always wise, especially if it would make the newly straightened teeth look broad.
Before treatment, ask about the planned contour, maintenance and limits. It also helps to know how the bonding fits with your orthodontist's retention plan and whether any further gum or restorative care is part of the picture.

Ask the dentist to explain exactly which feature will change and what will stay. This keeps the plan specific. Making the shadow smaller can be a good outcome even if eliminating it would leave a tooth looking too wide.
Find out what preparation each tooth would need and whether anything would be removed before resin is added. Cosmetic options differ here. Ask how the bonding could be repaired or replaced in future without disturbing your alignment.
Your smile on the day of bonding is only part of the result. Ask how the contacts, gums and composite will be checked over time, and who to contact if cleaning that area becomes hard or your retainer stops seating properly.
Your visit should cover how the teeth look and how the gums are doing. Ask what records we need and whether input from your orthodontist would help.
Let us know when your braces or aligners finished, what retainer you wear and any gum treatment you have had. The dentist assesses the teeth and gums. X-rays may help show bone levels and contact points that the visible space cannot reveal.
We discuss whether monitoring, gum care, bonding or a conversation with your orthodontist suits the findings. If bonding fits, ask how each tooth would change and how much reduction is sensible. Confirm the estimate and the upkeep involved.
With your agreement, the surfaces are prepared, resin is applied in layers, shaped and cured with a light. The contour has to work with the neighbouring tooth and the gum edge. You can ask for an explanation or a break at any time.
The bonding is polished and checked. Bring your retainer so its fit can be reviewed. You will practise flossing or brushing through the bonded spot before leaving, and we go over any remaining gap, the new shape and your next appointment.
The gap may look smaller, but it still needs daily cleaning. Use the method you were shown, and tell us if your floss or brush no longer slides through, or if your retainer feels different.
Ask which floss or interdental brush suits the bonded area, and in which size. Ease it through gently, never forcing it. If floss keeps tearing or catching, book a check so we can look at the contact.
Avoid chewing ice or hard objects, and do not use your front teeth to open things. Let us know about a rough spot, chip or shape change. Do not try to smooth or glue it yourself; the right fix depends on the surface.
Wear your retainer as instructed and stay with your recall and periodontal schedule. Mention lasting bleeding, trapped food or a new space. Bonding does not remove the need to monitor gums and bone.

Bring any question about your smile, your retainer or your cleaning routine. Answers should apply to your space, not a set package.
Many people make the trip from Burlington once their orthodontics wraps up. Visit our Bronte Street practice to talk over the spaces near your gumline, how cleaning is going and the options that might suit your newly aligned smile, and hear our findings before you decide anything.
Suitability depends on tooth shape, position and gum health. Cosmetic bonding is not a treatment for active gum disease.
