You just had your braces fitted, or changed your aligner tray last night, and your teeth are sensitive, almost painful at the slightest contact. Is this normal? How long will it last? And above all, what should you really expect in the days that follow?
Here's, without downplaying or overdramatizing, what's actually happening.
What's normal, and why
The discomfort you feel comes from the very mechanism of treatment. Gentle, continuous pressure is applied to the teeth to gradually move them within the bone, and this pressure is naturally noticeable, especially in the first few days after each intervention. It's not a sign that something's wrong: on the contrary, it's a sign that treatment is working.
With fixed braces, sensitivity is most pronounced in the 3 to 5 days following the initial fitting, then after each wire adjustment, usually every 4 to 8 weeks. The brackets and wire can also mechanically irritate the inside of the cheek or lip while these tissues get used to their presence.
With aligners, pressure is felt with each new tray, corresponding to the slight movement programmed for that stage. This sensation usually lasts 1 to 3 days after each change, then eases until the next change.
What actually helps ease it
Orthodontic wax is your number one ally against mechanical irritation from braces: a small ball applied to the bracket or wire section that's rubbing creates a smooth barrier between the metal and the mucosa while the area adjusts.
Adjusted eating for the first few days limits discomfort while chewing: temporarily favor soft foods or food cut into small pieces (pasta, eggs, fish, mashed potatoes, yogurt), and avoid anything very hard, sticky, or that you'd bite into with your front teeth.
A warm salt-water rinse can soothe mucosa irritated by rubbing against the brackets, particularly in the very first few days.
A simple pain reliever, at usual doses, can be used the first few days if discomfort warrants it — it's not systematically necessary, and most patients don't need it after the initial adjustment phase.
The signs that deserve a call to your orthodontist
The vast majority of appliance-related discomfort resolves with the measures above and time. Some signs, however, fall outside the expected pattern:
- pain that intensifies instead of decreasing after several days;
- pain concentrated on a single tooth, rather than spread across the arch;
- a detached bracket or band, or a wire poking out and actively hurting the cheek;
- a sore that isn't healing despite orthodontic wax;
- discomfort that persists beyond a week with no improvement.
These situations are most often resolved with a simple adjustment at the clinic, without calling the treatment itself into question.
The emergencies that don't wait
Certain signs aren't related to orthodontics and require immediate care, regardless of the appliance: swelling of the face or neck that's spreading, difficulty swallowing or breathing, a high fever combined with dental pain. A spreading dental infection is a life-threatening emergency — call 101 or go to the ER immediately.
What else helps, less known but just as useful
A cold compress on the cheek, applied on the outside for 10 to 15 minutes, can reduce the feeling of pressure in the very first days after fitting, particularly before bed if the discomfort disrupts falling asleep.
Drinking cool water rather than very hot or very cold in the first few days limits spikes in sensitivity, as certain teeth in the process of moving temporarily become more reactive to temperature changes.
Avoid "testing" the discomfort by deliberately biting down on the sore teeth to "see if it still hurts": this common reflex prolongs the irritation rather than easing it.
For children and teenagers, explaining in advance that this discomfort is normal and temporary limits the anxiety that, on its own, can amplify how pain is perceived in the first few days after each appointment.
What the research says
Studies on pain associated with orthodontic treatment describe a consistent pattern: a peak in sensitivity within 24 to 72 hours after each intervention (fitting, adjustment, tray change), followed by a gradual decrease over the following days. This pattern is similar in its progression regardless of appliance type — braces or aligners — even though the mechanism of mechanical irritation differs.
Hesitating to start treatment because of the pain you're dreading? The discomfort is real, but it's temporary, predictable, and manageable. Find an orthodontist near you on OlamKal and book an appointment to discuss it.
In practice, in Israel
Orthodontic wax is generally provided by your orthodontist when the braces are fitted and is available at pharmacies if you need to buy more. If you're unsure about unusual pain between scheduled appointments, contact the clinic directly: most minor adjustments are resolved in a few minutes, without waiting for the next follow-up visit.
To wrap up
Discomfort after getting braces fitted or adjusted is real, expected, and temporary — it shouldn't be ignored to the point of unnecessary suffering, nor turned into a source of excessive worry. With wax, adjusted eating for a few days, and a simple pain reliever if needed, most patients get through this phase without major difficulty.
