Gap Closure with Dental Bonding in Burlington

Did a gap reappear after braces, once the retainer went back in the drawer? From Burlington, you can have the returning space assessed along with tooth proportions, gum health and your bite, then compare whether composite bonding, more orthodontic care or a mix of the two suits you.

When spacing returns

Braces closed it once. Now it is back.

Teeth tend to drift after orthodontic treatment, especially when a retainer is worn less over time. A small gap can creep back between the front teeth. Bonding is one possible response: composite in a matching shade is added to the sides of the teeth, making them slightly wider instead of moving them back into place.

That difference is worth understanding before you choose. Bonding changes tooth shape, while orthodontics changes tooth position. You are also free to leave a returning gap if it does not bother you. When you would like it changed, the clinician will consider its cause, its width, and whether the teeth are still moving.

Coming from Burlington, it helps to bring any retainer you still have to the first appointment at our Bronte Street practice. Tell us what you liked about the result after braces and what has changed since. We can then examine the area and lay out bonding beside the other sensible options.

Sorting out the cause

Why did the space come back?

The answer guides the plan. Mention your orthodontic history, any symptoms, and other dental work, so the clinician can judge whether cosmetic bonding is a reasonable next step.

A small, settled gap after treatment

If the gap has stayed the same for a while, think about whether you want it closed or just reduced. Composite widens the teeth involved, so their shape will be looked at closely. Natural-looking proportions often matter more than closing every fraction of a millimetre.

Spacing that keeps growing

Point out any gum bleeding, looseness, or change in your bite. A gap that continues to widen may involve the gums and bone, or other factors besides relapse. It needs to be understood before any material is used to hide it.

A retainer that no longer fits well

Bring the retainer and any records of your treatment. The clinician can look at current tooth position, earlier composite, and how a new result would be held. Ask how changing the tooth outline would affect a retainer you might wear again.

If the space is where a tooth is missing rather than between two neighbours, gap bonding may not be appropriate. Let the team know about any tooth that never formed, was extracted, or was lost.

Where bonding can help

A quieter gap, still in proportion.

With suitable teeth, composite is shaped onto the edges beside the gap to give a new outline. Careful shade choice and polishing help it blend. The plan must also suit how the teeth contact each other and how they come together when you chew.

Bonded composite can stain, wear or chip as the years pass, and it may need polishing, repair or replacement. Because a returning gap may also keep shifting, ask how stability will be managed. Make the decision knowing the upkeep, not only the first result.

A targeted fix rather than a full redo

You can ask about the gap alone without starting a broader cosmetic plan. Find out which teeth would receive composite and why. The plan should describe effects on nearby teeth rather than assuming they also need treatment.

A clear view of orthodontic alternatives

Ask whether reshaping, renewed tooth movement or a combination is better suited to your relapse. Each has a different commitment. Speed alone does not make bonding the best answer if the teeth are still on the move.

Cleaning that stays manageable

Discuss how you will floss or use another aid at the new contact. Ask how the gumline will be reached once composite is added. A narrower gap is only helpful if the area can still be kept clean.

The bonding appointment path

Check stability first, then shape.

Bonding should follow a clear discussion of whether it suits you and what else could be done. Ask how the shape will be planned and whether retention or other care should come first.

  1. Assessment of the gap and your orthodontic history

    Share when the space returned, details of past braces or aligners, and any fillings nearby. The clinician examines your teeth, gums and bite. Records or an orthodontic opinion may be suggested before any cosmetic recommendation.

  2. Agreeing on shape and how it will be held

    Discuss the planned tooth width and whether to close the gap fully or partly. Ask about preparation, shade, fees, upkeep and retention. Compare bonding with further orthodontics and with leaving a healthy gap as it is.

  3. Composite added and sculpted

    When you agree to proceed, the tooth surfaces are prepared and resin is built up and shaped. A curing light sets the material. The clinician refines the contact with the neighbouring tooth and the edge near the gum.

  4. Polish, check the bite, and learn the cleaning

    The surfaces are polished, and your bite and contact are checked. Ask to see how to clean between the treated teeth. Look at the result and any remaining space, and confirm your review plan before you leave.

Keeping the result steady

Clean well, protect the edges, and watch for drift.

Use the cleaning method demonstrated for your new tooth shapes, and follow any retention advice you are given. The teeth are still separate and the contact between them needs daily care.

Work floss through gently

Use the recommended aid without forcing it, and ask for help if it will not pass as shown. Floss that shreds or keeps catching, or trouble reaching the gumline, should be checked. Keep cleaning the area even though the gap is less visible.

Avoid putting the bonding under strain

Do not bite on hard items or use your teeth as tools. Tell the clinician about clenching or grinding and ask whether it should be assessed. Any protection should be planned for you, not assumed to come with the composite.

Report chips, stains, or renewed spacing

Arrange a review if an edge feels rough, composite breaks away, or the gap seems to be returning again. The cause determines whether polishing, repair, or another assessment is needed. Avoid trying to repair or reshape it yourself.

Weighing your choices

Reshape, realign, or leave it be?

Ask what each route would change and what it would leave untouched. Depending on findings, the plan may be cosmetic, orthodontic, restorative, or begin with your gums.

When extra width still looks natural

Bonding the neighbouring teeth

Bonding can suit a gap where the teeth beside it can take added composite and keep a cleanable contact. Ask whether one or both teeth would be built up and how you would maintain them. Suitability is not set by gap size alone.

When the teeth need repositioning

Further orthodontics or a combined sequence

Moving teeth again addresses spacing differently from widening them. Some relapse cases are best handled in planned stages. Ask why a particular order is recommended and what retention would follow.

When another issue is behind the gap

Gum care, tooth replacement, or watching

Gum-related movement or a missing tooth needs its own assessment. A stable, healthy gap can also be left alone. Ask which decisions concern your oral health and which are about the look you prefer.

Burlington bonding FAQs

Questions worth asking after braces.

Ask how the plan relates to your retention, tooth width, bite and cleaning. Suitability depends on more than whether the gap looks small.

(905) 876-4488
Why did my gap come back years after braces?
Teeth can shift over time after orthodontic treatment, particularly if a retainer is worn less. Gum changes and other factors can also play a part. An exam helps work out the likely reason before any closure is planned.
Should I start wearing my old retainer again before bonding?
Ask the clinician before you do. An old retainer may no longer fit as it should, and forcing it could be uncomfortable. Bring it to your appointment so it can be checked alongside your current tooth position.
Will bonding stop my teeth from drifting further?
No. Composite changes the shape of the teeth, not their tendency to move. If drifting is a concern, ask about retention or orthodontic options as part of the plan, and how bonding would fit with them.
Can bonding be done if I might want aligners later?
Mention any orthodontic plans early. Adding composite first could affect later tooth movement or need adjusting afterwards. The clinician can explain which order would make more sense for your situation.
Is it normal for the bonded teeth to feel slightly different to my tongue?
A new contour can feel unfamiliar at first. If an edge feels sharp, rough, or catches food or floss, mention it so the shape can be checked and smoothed where appropriate.
How should I plan appointments from Burlington around work?
Ask at the consultation how many visits your plan will likely take. Evening appointments until 7pm are available Monday through Thursday, and weekend or Friday times can be arranged by appointment, which helps around a working day.
