Braces hurt because they’re forcing your teeth through solid bone. That’s not an exaggeration. When brackets and wires apply pressure to a tooth, your body responds with a localized inflammatory reaction that dissolves bone on one side and rebuilds it on the other. This process, called bone remodeling, is what actually moves your teeth into new positions. The pain you feel is a direct consequence of that inflammation, compressed blood vessels, and irritated nerves.
What’s Actually Happening Inside Your Jaw
Each tooth sits in a socket surrounded by a thin ligament that connects it to the jawbone. When braces push a tooth in one direction, this ligament gets compressed on one side and stretched on the other. That compression triggers your immune system to flood the area with inflammatory signaling molecules, the same type of chemicals your body releases when you sprain an ankle or get a cut. These molecules recruit specialized cells that break down the bone blocking the tooth’s path, while other cells build new bone behind it to fill the gap.
The compression also squeezes the tiny blood vessels that run through the ligament. Your dental pulp and surrounding vessels can only tolerate a certain amount of pressure before circulation gets disrupted. When blood flow is restricted, the tissue becomes temporarily starved of oxygen, which adds to the soreness and sensitivity you feel. The nerves threaded through the ligament are being physically compressed at the same time, which is why the pain can feel deep, achy, and hard to pinpoint.
This isn’t a sign that something is wrong. It’s the mechanism that makes orthodontic treatment work. Without that inflammatory response, your teeth wouldn’t move at all.
The Pain Timeline After Placement
Most people feel soreness within a few hours of getting braces on. The pain follows a predictable curve: about 70% of patients report the worst intensity the day after bonding, roughly 24 hours in. After that peak, discomfort gradually drops off over the next several days. By day seven, pain levels typically fall to near-baseline. The same pattern repeats after each adjustment, though many people find later adjustments less intense than the initial placement.
You’ll visit your orthodontist every four to six weeks for adjustments, where the archwires are tightened or swapped for thicker ones. Each visit reapplies pressure to specific teeth and restarts the bone remodeling cycle, so you can expect a few days of renewed soreness after every appointment.
Why Chewing Makes It Worse
Biting down adds force on top of the constant pressure your braces are already applying. Your teeth are sitting in inflamed, actively remodeling bone, and the ligament around each tooth is already compressed. Chewing pushes teeth further into that sensitive tissue, amplifying the pain signal.
For the first two or three days after getting braces or having them adjusted, sticking to soft foods makes a real difference. Mashed potatoes, yogurt, smoothies, scrambled eggs, and soup all require minimal chewing. As the soreness fades over the week, you can gradually return to normal eating. Hard, crunchy, or sticky foods are worth avoiding throughout treatment, not just for comfort but because aggressive chewing can pop a bracket loose or bend a wire.
Sores From Brackets and Wires
The deep ache from bone remodeling is only one type of braces pain. The other is surface-level: brackets and wire ends rubbing against the inside of your cheeks, lips, and tongue. This friction breaks down the delicate lining of your mouth, creating small ulcers that look like round lesions with a white or yellowish center surrounded by a red border. They can show up on the inner lips, cheeks, tongue, floor of the mouth, or soft palate.
Orthodontic wax is the most immediate fix. Pinching a small piece over a sharp bracket or poking wire creates a smooth barrier that stops the metal from grinding against the tissue, giving the sore a chance to heal. If a wire end is jabbing you, your orthodontist can trim or bend it at your next visit, or you can use wax as a temporary shield. Most people find their mouth gradually toughens up over the first few weeks, and these sores become less frequent as treatment continues.
What Helps With the Pain
Over-the-counter anti-inflammatory pain relievers are the most studied option for orthodontic soreness. Taking ibuprofen about an hour before your appointment, then again at three hours and seven hours afterward, has been shown to significantly reduce pain at the six-hour mark and through bedtime. The catch is that the effect wears off, and pain scores tend to rebound around the 24-hour mark, so continuing with regular doses through the first day or two is more effective than a single pill.
A meta-analysis comparing common pain relievers found no significant difference in relief between ibuprofen, acetaminophen, and aspirin, though ibuprofen outperformed placebo more consistently. There’s an ongoing debate about whether anti-inflammatory medications might slightly slow tooth movement by blocking the inflammatory chemicals that drive bone remodeling. Some clinicians argue that the short duration and low doses people actually take are cleared by the body before they meaningfully interfere with treatment. If you’re concerned, acetaminophen works on pain without affecting inflammation and is generally considered neutral for tooth movement.
Cold also helps. Sipping ice water or holding a cold pack against your jaw constricts blood vessels and temporarily numbs the area. Rinsing with warm salt water can soothe irritated gums and help mouth sores heal faster.
Clear Aligners Hurt Less, but Still Hurt
If you’re considering your options or wondering whether aligners would have been less painful, the answer is yes, but not pain-free. A comparative study of 100 patients found that those with traditional fixed braces reported an average pain score of 6.5 out of 10 at the 24-hour mark, while clear aligner patients averaged 4.2 out of 10. At three days, the gap was still significant: 5.7 for braces versus 3.8 for aligners. By two weeks, both groups had dropped to low levels (1.5 for braces, 1.0 for aligners). The underlying biology is the same, since aligners still move teeth through bone remodeling, but the lighter, more distributed forces and the absence of metal brackets rubbing against soft tissue account for the difference.
Pain That Isn’t Normal
Some discomfort is expected with every adjustment. But certain symptoms fall outside the normal pattern and deserve attention. Sharp, spontaneous pain in a single tooth that doesn’t fade after a week, sensitivity to cold that lingers or worsens over time, or a pinkish spot appearing on a tooth can signal that the root or the tissue inside the tooth is being damaged by excessive force. These are rare complications, not routine soreness, and they require your orthodontist to evaluate whether the forces on that tooth need to be reduced or the treatment plan adjusted.
Persistent pain that stays at the same intensity beyond seven to ten days after an adjustment, rather than gradually improving, is also worth mentioning at your next appointment. Normal orthodontic pain follows a clear arc: it peaks, then fades. Pain that plateaus or gets worse is telling you something different.
