Braces hurt because they work by pushing your teeth out of position, triggering an inflammatory response in the tissues surrounding each tooth. About 90% of orthodontic patients experience pain after their braces are first installed, and the discomfort returns briefly after each adjustment. The good news: the pain is predictable, short-lived, and manageable once you understand what’s happening.
What’s Actually Happening Inside Your Gums
Each tooth sits in a socket lined by a thin layer of tissue called the periodontal ligament. When braces apply pressure to a tooth, they compress this ligament on one side and stretch it on the other. Your body interprets that compression as a signal to remodel bone: it breaks down bone on the side being pushed and builds new bone on the side being pulled. That’s how teeth actually move.
The bone-remodeling process requires inflammation. Your body releases inflammatory chemicals (the same ones involved in a sprained ankle or a bruise) to recruit cells that dissolve bone tissue. Those chemicals also sensitize nearby nerve endings, which is why your teeth feel sore and tender to the touch. The pain isn’t a sign that something is wrong. It’s a sign that the biological process of tooth movement is underway.
Two Types of Braces Pain
Pressure Soreness
This is the deep, aching tenderness you feel in your teeth and jaw. It’s caused by the inflammatory response described above and is most intense in the first day or two after getting braces or having them tightened. Biting down on food is usually the worst part, since chewing adds force to teeth that are already under pressure. Even closing your teeth together gently can feel uncomfortable during this window.
Soft Tissue Irritation
Brackets, wires, and bands are hard metal objects sitting against the soft, delicate lining of your mouth. The inner lips, cheeks, and tongue rub against these surfaces hundreds of times a day while talking and eating. That friction can break down the tissue and cause small sores, often round or oval with a white or yellowish center. The sharp edges of brackets and the cut ends of archwires are the most common culprits. This type of irritation is usually worst in the first few weeks, before the inside of your mouth toughens up and forms a thicker protective layer.
When the Pain Peaks and How Long It Lasts
After your braces are first placed, discomfort typically peaks within 24 to 48 hours. Most people describe it as “annoying,” “sore,” and “tight” rather than sharp or severe. By the end of the first week, the soreness fades significantly as the initial burst of inflammation settles down.
Each follow-up adjustment restarts a smaller version of this cycle. After a tightening visit, teeth tend to feel tender for one to three days. The pattern becomes familiar: soreness builds over the first day, peaks overnight or the next morning, then gradually eases. Over the course of treatment, many patients find that each adjustment bothers them less than the one before, likely because the teeth have less distance left to move and the body adapts to the process.
Over-the-Counter Pain Relief
Both acetaminophen (Tylenol) and ibuprofen (Advil, Motrin) are commonly recommended for braces pain. A clinical trial comparing the two found no significant difference in pain relief after orthodontic treatment. Both reduced discomfort to a similar degree, so you can use whichever you tolerate better.
Some orthodontists suggest taking a dose about an hour before your appointment so it’s already working by the time the adjustment is finished. For most people, pain relief is only needed for the first day or two after tightening.
Managing Soft Tissue Soreness With Wax
Orthodontic wax is a simple, effective fix for brackets and wires that dig into your cheeks or lips. It’s a soft, pliable material that you press directly onto the offending piece of hardware to create a smooth buffer between the metal and your tissue. Here’s how to use it:
- Clean first. Wash your hands and brush your teeth so the wax sticks well and bacteria don’t get trapped underneath.
- Size it right. Pinch off a pea-sized piece and roll it between your fingers until it softens from your body heat.
- Press it on. Flatten the ball slightly and push it onto the bracket or wire section causing the irritation. You can use your tongue to adjust the placement.
The wax is safe to accidentally swallow and can be reapplied as needed throughout the day. If a wire end is poking you and wax isn’t enough, your orthodontist can trim or bend the wire at your next visit.
Eating During the Sore Days
The first 48 to 72 hours after getting braces or having them tightened is when chewing feels the most uncomfortable. Sticking to soft foods during this window makes a real difference. Cold foods and drinks can also help numb the soreness.
Good options include scrambled eggs, yogurt, mashed potatoes, oatmeal, pasta, soup with soft vegetables, smoothies, applesauce, soft-cooked rice, avocado, and ice cream. Shredded or ground meat works if you want something more substantial. The goal is to avoid anything that requires you to bite down hard or tear with your front teeth, like crusty bread, raw carrots, or tough meat.
By about day three or four, most people can return to a more normal diet. You’ll still want to avoid very hard, crunchy, or sticky foods for the duration of treatment (think popcorn kernels, hard candy, and caramel), since those can damage brackets and wires, leading to extra appointments and more soreness.
Why Some Appointments Hurt More Than Others
Not every adjustment produces the same level of discomfort. Visits where your orthodontist switches to a thicker or stiffer wire tend to cause more soreness because the new wire applies greater force. Early appointments, when teeth have the most moving to do, are generally more uncomfortable than later ones. Adjustments that only involve minor tweaks, like replacing a rubber band or making a small bend in the wire, may cause little to no pain at all.
If you notice that one particular tooth is significantly more painful than the rest, or if pain from an adjustment hasn’t improved after five to seven days, it’s worth calling your orthodontist. Persistent pain in a single tooth can occasionally mean the wire is applying too much force in one spot, and a quick adjustment can fix it.
