Most conversations about straightening teeth stop at the picture. Before and after. Crooked, then not. What gets left out is the part that decides whether the treatment works at all, which is the biology sitting underneath the plastic. A tray does not shove a tooth sideways the way a hand shoves furniture across a floor. It applies a small, steady load, and the bone responds to that load over weeks by dissolving on one side of the root and rebuilding on the other. Slow. Measurable. Easy to derail if the load stops arriving on schedule. That gap between what patients picture and what happens inside the jaw accounts for most of the frustration people report halfway through treatment.
Underneath that sits a set of decisions made before the first tray is ever printed. Which teeth need to rotate. Which need to tip. Which need to move bodily through bone, roots and all, which is the hardest ask you can hand a removable appliance. Someone reading up on clear aligners for misaligned teeth after a checkup is really trying to understand a staged mechanical plan that runs on a schedule they control themselves.
Sacramento patients reach this question at every age now. Adults who wore braces at fourteen and watched the lower front teeth creep back. Parents weighing options for a teenager who hates metal. Samuel Dental Care is one of the Sacramento practices offering aligner treatment alongside general dental care. Nothing here is a recommendation of any specific provider. This piece walks through what happens between the first scan and the last retainer, and where treatment tends to go wrong.
What Misaligned Teeth Actually Means
Crowding is the version everyone pictures. Teeth overlapping because the jaw ran out of room somewhere around age twelve. There is also spacing, rotation, tipped teeth, and jaw relationships that are misaligned where the upper and lower arches meet. NIH-hosted health information on misaligned teeth and jaws notes that some people notice no symptoms at all, while others struggle with eating, drinking, or speech, depending on the type and severity. It flags something patients rarely connect to. Certain misalignments can make one or two teeth genuinely hard to clean, which increases the risk of decay and gum disease over time. The clinical name for all of it is malocclusion.
How a Piece of Plastic Moves Bone
Force, then time. Each aligner is made slightly out of position relative to where your tooth currently sits, so when it seats, the plastic wants to spring back toward its own shape. That pressure transfers to the tooth. The ligament wraps around the root, compressing on one side and stretching on the other, and cells respond by remodeling the socket. More force does not speed any of this up. Push too hard and the process stalls, with root damage as the risk at the far end. That is why trays change on a set schedule, and each one moves a tooth by a fraction of a millimeter rather than an amount you could see in a mirror.
Attachments, and Why Smooth Plastic Is Not Enough
Small tooth-colored composite bumps get bonded to certain teeth before treatment starts. Attachments. A smooth tray sliding over a smooth tooth has nothing to grip, so rotating a rounded premolar is close to impossible without them. The bump gives the plastic a surface to push against, and the direction it faces is planned deliberately. They come off with polishing at the end. Nothing gets drilled to put them on. Most patients register them for about a week and then stop noticing. Their placement is mapped at the same time as the tray sequence, because neither half works without the other.
Wear Time Is the Treatment
Twenty-two hours a day. That figure carries more weight than any other instruction in the plan. Trays come out for meals and for anything other than water, then go back in straight away. Teeth move only under sustained pressure, so a tray left out for four hours a day changes the arithmetic of the whole plan. Teeth also drift back a little between wears, which means lost hours cost more than they appear to. Patients who finish close to their projected date are usually the ones treating those two free hours as a fixed budget rather than a rough guide.
The Cleaning Problem Hiding Behind Crooked Teeth
Overlapped lower incisors are the classic trap. Floss shreds in the same contact every visit, plaque sits there undisturbed, and the gum in that spot bleeds a little at every cleaning. Straightening those contacts is a hygiene result before it is a cosmetic one. A dentist who checks gum health before starting alignment has a practical reason for the order, since moving teeth through inflamed tissue often ends badly. Gums settled first. Movement second.
What Aligners Will Not Fix
Jaw pain is the common misunderstanding. Patients arrive assuming a bite correction will settle a clicking or aching joint, and that assumption has decades of dental folklore behind it. Guidance from the National Institute of Dental and Craniofacial Research on temporomandibular disorders states that current evidence does not support a strong link between malocclusion and TMD, and cautions against irreversible occlusal treatments that permanently alter the teeth, bite, or jaw joints. Straightening may still suit your mouth for other reasons. Treating it as a cure for jaw pain is a separate claim, and the support for that one is thin.
Retention, or Why the Last Tray Is Not the Finish Line
Ligaments tug teeth back toward their old positions the moment pressure stops. The bone around the new position needs months to settle properly. A retainer holds the result while that happens, worn full time at first and then overnight, usually indefinitely. Skip it, and months of work can unravel in a year, with the lower front teeth almost always the first to give the game away. Adult teeth keep shifting anyway, from grinding and from tooth loss, so a retainer stays useful long after the trays are gone.

Questions Worth Asking Before You Start
Ask what kind of movement your case needs and whether a tray can deliver it, because bodily movement and large bite corrections sit at the edge of what removable appliances do well. Ask how many trays are planned and what happens if teeth stop tracking, since mid-course corrections are routine rather than a sign of failure. Ask who checks progress and how often. Ask what the retainer costs and how long you will wear it, because that answer belongs in the price whether or not it appears on the quote. A staged plan, you understand, is one you are far more likely to finish on schedule.
