Yes, orthodontists do remove teeth as part of treatment, though it happens less often than it used to. Roughly 41% of orthodontic cases today involve extractions, down from about 61% in 1980. Whether you’ll need teeth removed depends on how crowded your teeth are, how much your front teeth protrude, and whether alternatives like expanders or enamel reshaping can create enough space on their own.
Why Teeth Are Removed for Braces
Orthodontic treatment works by moving teeth into better positions, and that movement requires space. When your jaw simply isn’t large enough to fit all your teeth in a straight line, removing one or more teeth gives the remaining teeth room to shift. The most common reasons for extraction include severe crowding, protruding front teeth, a convex facial profile, and significant misalignment between the upper and lower jaws.
Think of it like a parking lot with too many cars. You can squeeze everyone in at odd angles, or you can remove a car and let the rest park properly. Extraction creates the space your orthodontist needs to align everything without pushing teeth into unstable positions or compromising your bite.
Which Teeth Get Removed
First premolars are by far the most common choice. These are the teeth sitting between your canines (the pointy ones) and your molars, roughly the fourth tooth back from center. They’re selected because of their location and size: pulling them creates space right where it’s needed most, allowing the front teeth to be pulled back into alignment.
Second premolars (one tooth further back) are sometimes removed instead, but this is typically reserved for milder cases. They’re not a good option when there’s a large discrepancy to correct because the space they create is too far from the front teeth to be useful. In some treatment plans, four premolars are removed (two from each jaw) to balance the bite symmetrically.
What About Wisdom Teeth?
Wisdom teeth are a separate issue from orthodontic extractions. If your wisdom teeth are growing in straight and have enough room, they won’t interfere with braces and don’t need to come out for orthodontic reasons. The concern arises when wisdom teeth are impacted, meaning they’re growing sideways or pressing into neighboring teeth. In an already crowded mouth, impacted wisdom teeth can cause pain and complicate treatment, so removal may be recommended before or during braces. But your orthodontist won’t pull wisdom teeth just to create space for alignment. That’s what premolar extractions are for.
How Extractions Affect Your Face
A common worry is that removing teeth will make your face look “dished in” or flat. Research on 160 patients who had four first premolars removed found that 80% to 90% of them ended up with improved or satisfactory facial profiles after treatment. The upper and lower lips moved back by about 3.4 and 3.6 millimeters respectively, which in most cases simply reduced excessive protrusion rather than creating a sunken look.
That said, roughly 10% to 15% of patients in that study ended up with profiles considered excessively flat. And interestingly, 5% to 25% of patients (depending on which measurement was used) actually had more protrusive lips after treatment, not less. The takeaway: extractions don’t automatically flatten your face, but the outcome depends on your starting anatomy and how aggressively the front teeth are pulled back. This is something worth discussing with your orthodontist before treatment begins.
Alternatives to Extraction
Modern orthodontics offers several ways to create space without pulling teeth, and these options are a big reason extraction rates have dropped by about 20 percentage points over the past three decades.
Palatal Expansion
For younger patients whose jaws are still growing, a palate expander can widen the upper jaw to make room for crowded teeth. This works best between ages 8 and 10 during the mixed dentition phase, when baby teeth and adult teeth are both present. Research comparing early expansion to later orthodontic treatment found that kids treated with expanders gained an average of 4.5 mm of space in about 12 months, while teens treated later gained only 3.2 mm over roughly 25 months. Early intervention corrected more crowding in half the time. For adults whose palatal suture has fused, traditional expanders don’t work, though surgically assisted expansion is sometimes an option.
Interproximal Reduction
Interproximal reduction, often called IPR or “tooth slimming,” involves carefully removing thin strips of enamel from between teeth. It sounds aggressive, but the amounts are tiny. In the front of the mouth, orthodontists typically remove no more than 0.3 mm from upper incisors and 0.2 mm from lower incisors per contact point. Across the side teeth, the procedure can free up around 8 mm of space per arch. This makes IPR a realistic alternative for minor to moderate crowding in the range of 4 to 8 mm, but it won’t replace extractions when crowding is severe.
Arch Development
Some orthodontists use specialized wires or appliances to tip the teeth outward slightly, expanding the dental arch without widening the jaw bone itself. This approach can gain a few millimeters but has limits. Pushing teeth too far outside the bone leads to gum recession and instability.
What to Expect if You Need Extractions
The extractions themselves are usually performed by an oral surgeon or general dentist, not the orthodontist. Premolar extractions are straightforward procedures done under local anesthesia, and recovery typically takes a few days. Most orthodontists recommend waiting at least two to three weeks after the extraction before placing braces or attachments, giving the gum tissue time to heal and the initial bone remodeling to begin.
Once braces go on, the gaps where the teeth were removed close gradually over months as the surrounding teeth are guided into the empty space. By the end of treatment, there should be no visible gaps. The total treatment timeline with extractions tends to be longer than non-extraction cases, often by several months, because closing extraction spaces requires careful, controlled tooth movement.
If your orthodontist recommends extractions, it’s reasonable to ask what the specific indication is, whether any alternatives were considered, and how the plan will affect your facial profile. A good orthodontist will have already weighed these factors and can walk you through the reasoning with your X-rays and models in hand.
