Can Invisalign Close Wide Gaps After Tooth Extraction?
Yes, Invisalign can successfully close wide gaps left after tooth extractions. This is actually one of the most common applications for Invisible braces, particularly when premolars are extracted to create space for treating severe crowding.
The treatment gradually shifts surrounding teeth into the empty space, eliminating the gap entirely.

How Does Invisalign Move Teeth Into Extraction Spaces?
Invisalign works by moving a tissue called the periodontal ligament with gentle pressure. Your teeth aren't actually fused to your jawbone – they're held in place by the periodontal ligament, a fibrous tissue that acts like a hammock.
When consistent, gentle pressure is applied (exactly what Invisalign does), the bone on the pressure side gradually resorbs whilst new bone forms on the tension side.
This process takes time, which is why closing extraction gaps typically requires 12 to 24 months of treatment. Smaller gaps might close in 12 to 18 months, whilst wider spaces or cases involving multiple extractions can extend beyond two years.
Your specific timeline depends on several factors: the gap width, how many teeth need moving, your age, bone density, and crucially, how consistently you wear your aligners.
What Happens to Your Bite as the Gap Closes With Invisalign?
Throughout gap closure treatment, you can expect:
Noticeable pressure and soreness during the first few days of each new aligner
Gradual changes in how your teeth come together when biting
Temporary difficulty chewing on the side where the gap is closing
Visible progress as the space narrows month by month
Improved facial profile as teeth move into optimal positions
The bone where your tooth was extracted gradually fills in as adjacent teeth move into the space. This remodelling is permanent, provided you wear retainers after treatment. Without lifelong retention, teeth will drift and gaps can partially reopen – undoing months of work.
Is Closing Extraction Gaps Right for Everyone?
No, not every extraction gap should be closed. Wisdom tooth extractions, for example, leave gaps at the very back of your mouth that don't need closing – there's nothing behind them to move forward, and closing these spaces serves no purpose.
Similarly, if you've lost a tooth due to trauma or decay rather than orthodontic planning, an implant or bridge might be more appropriate than gap closure.
The decision to close extraction gaps should consider your facial profile as well. Moving teeth backwards to close gaps can slightly reduce lip fullness and change your profile.
A skilled dentist plans treatment to enhance rather than detract from your natural features, sometimes leaving small spaces if closing them completely would negatively impact your appearance.
What to Expect During Invisalign Treatment
The process begins with a healing period after extraction. You'll need to wait at least two to four weeks before starting Invisalign to allow the extraction site to close and initial healing to occur. Rushing into treatment too soon can cause complications and discomfort.
Throughout treatment, you'll feel pressure and soreness, particularly in the first few days of each new aligner. This is strongest during the initial months when teeth are making their longest movements. Over-the-counter painkillers manage this effectively for most patients.
