Hello, I'm Dr. Junghoon Choi, a Korean board-certified prosthodontist and the lead dentist of Seoul Crown Dental Clinic in Gangnam.
"I had three crowns placed last year, and ever since my bite has felt slightly off — like my teeth don't meet quite right. Could that be from the crowns?"
"My jaw has been sore and I keep biting unevenly since getting a new crown. Is that something a prosthodontist can fix, or does the crown need to be remade?"
Short answer: A bite that feels wrong after crown placement has several distinct causes — crown height, chewing-surface shape, a shift in how multiple teeth meet together, or a jaw-muscle response. Which cause is present, and whether an adjustment or a full redesign is needed, can only be determined by an in-person examination. If you are visiting Seoul, consultations with me are held directly in English.
When a crown replaces a tooth surface, even a small difference in height or contour can feel significant, because the jaw muscles are sensitive to very small changes. There are several distinct reasons a bite can feel wrong after crowns, and they often overlap.
The most straightforward mismatch is a crown that is a fraction too tall, so it contacts the opposing tooth before everything else does. This can make the jaw sore after chewing. A crown that sits slightly too low creates a different problem — surrounding teeth can carry more load, and the chewing pattern can shift. Height discrepancies often respond well to careful adjustment, but removing too much flattens the anatomy and creates a new problem.
A crown with inadequate occlusal anatomy (the hills and valleys on the chewing surface) can make the bite feel vague or unstable even when height is technically correct. Teeth guide each other through small lateral movements when chewing; if those guiding surfaces are absent or poorly shaped, the jaw searches for a stable position and the muscles work harder than they should. This usually cannot be resolved by grinding down alone — the surface shape itself needs attention.
When several teeth are crowned together, the way the teeth come together can change as a whole. The result is sometimes a bite that feels globally different rather than one specific tooth hitting first. This situation is more complex because the relationship between the upper and lower arches as a whole may need to be re-evaluated. When several crowns are made together, the overall height of the bite can also change, and that is one of the first things I check.
Even if the bite feels fine when you close straight down, a crown can catch during side-to-side or forward movements. This kind of interference often causes muscle soreness and is checked separately from the closed bite.
The muscles that move the jaw adapt to occlusal changes, but adaptation takes time and can involve soreness or fatigue. A pre-existing clenching or grinding habit (bruxism) means the muscles may already have been under stress before the crowns were placed, making that tension more noticeable afterward. Distinguishing a muscle-driven bite problem from a purely crown-driven one is part of the examination. You can read more about how nighttime clenching affects restorations in Why Does My Crown Keep Breaking? The Role of Nighttime Clenching and Bite in Restoration Longevity.
The examination starts with how you describe the problem — which tooth, when it feels off, whether it is worse in the morning or after meals, and how long it has been present. Articulating paper (a thin, ink-coated film placed between the teeth) then shows where and how strongly the teeth are contacting, revealing whether one area is carrying disproportionate load.
I also assess jaw movement: how the lower jaw tracks forward and to the sides, whether it deviates, and where the teeth guide each other through those movements. For cases involving multiple crowns or a significant shift in the overall bite, I evaluate muscle tenderness and jaw-joint range of motion as well, because the muscles and joints often reflect what has been happening at the tooth level. I also check whether the discomfort is coming from the tooth itself, such as the nerve or the surrounding gum, using X-rays and tests, because that can feel like a high bite too. Any existing X-rays or records you bring along help with scheduling — clinical judgment is made at the examination itself.
If jaw muscle or joint symptoms are active, I usually stabilize the jaw first, often with a splint, before adjusting or remaking crowns. Changing the crowns while the jaw position is still shifting can make the problem harder to solve.
An adjustment — carefully reshaping part of the crown surface — can resolve the problem when the issue is limited to a height discrepancy or a specific contact point that is too strong. The adjustment has to be done methodically, confirming the bite at each stage. There is also a limit to how much a crown can be adjusted. Zirconia and ceramic crowns need a minimum thickness, so a crown that is significantly high may need to be remade rather than ground down.
A redesign is more likely needed when the crown shape itself is inadequate, when multiple crowns have collectively shifted the bite reference, or when adjustment has been attempted several times without a stable result. Repeating the same adjustment tends not to help when the crown's shape itself is the issue. The article Told You Need a New Crown? Here Is What a Prosthodontist Checks First covers the evaluation process in more detail.
When the plan involves remaking multiple crowns or making significant changes to how the teeth meet, I often use a provisional (temporary) phase before the final crowns are made. Temporary crowns are placed with the intended new bite built in, and you wear them through daily function — chewing, speaking, and your normal habits — for a period decided at the examination.
If the bite feels stable and comfortable during that period, it serves as a trial before the partner dental laboratory fabricates the final restorations. If something still needs adjustment, it is easier to modify temporary crowns than to alter a finished final crown. This step is not always needed, but for complex bite changes it is an important part of designing something that holds up over time.
A slight difference in feel can settle within a few days, but a crown that feels high when you bite should be checked early rather than waited out. If the discomfort is mild and there is no concerning symptom at the tooth itself, an early follow-up check is often the right first step rather than an immediate remake. Remaking a crown that may settle on its own is not without consequence: the tooth may need additional preparation. The decision to remake should follow a structured examination, not the discomfort alone.
Q. My crowns were adjusted twice and my bite still feels off. What might have been missed?
When adjustments have not resolved the problem, I look at whether the issue is with height, surface shape, or the overall relationship between the arches — because each requires a different approach. I also assess whether the jaw muscles have developed a compensating pattern that is now maintaining the asymmetry even after the teeth were corrected. That distinction matters for deciding whether further adjustment can work or whether the restoration design needs to change.
Q. Can a bite problem from crowns cause jaw soreness or headaches?
It can. When the teeth do not meet evenly, the jaw muscles work harder to find a stable chewing position, and sustained muscle effort of that kind tends to cause soreness in the jaw, temples, or the area in front of the ear. Whether that is what is causing your symptoms needs to be confirmed in person — jaw soreness and headaches have more than one possible cause, and I am not able to diagnose symptoms remotely from messages or photos.
Q. I'm visiting Seoul for a limited time. Can a bite problem be evaluated and treated during my stay?
What can be done during a single stay depends entirely on what the examination finds. A straightforward adjustment may be completed in relatively few visits. If the situation involves remaking crowns or working through a provisional phase, that requires at least two visits and a fabrication period at the partner laboratory — stages are planned individually, and a return visit here is usually part of the plan. Sending your travel dates and any existing records before arrival helps with scheduling, though all clinical decisions are made at the examination.
Q. If crowns need to be remade, how is the timeline planned around my travel dates?
The timeline differs for each person and is confirmed at the examination. What determines it includes how many teeth are involved, whether a provisional phase is needed, the fabrication time at the partner laboratory, and any bite adjustment or try-in steps along the way. Because fabrication goes through a partner laboratory, a final crown requires at least two visits. If your travel schedule is fixed, I plan the stages around your dates before treatment begins — and if part of the treatment extends beyond your stay, a return visit here is how we finish it.
