Clear Aligners in San Ramon, CA
Clear aligners are a series of removable plastic trays, each shaped to move teeth a fraction of a millimeter, worn about twenty-two hours a day and changed weekly. They correct mild to moderate crowding, spacing and bite problems. Treatment commonly runs six to twenty-four months, followed by a retainer.

What are clear aligners and how do they work?
A clear aligner is a thin, transparent tray moulded to fit over your teeth — but not quite to their current position. Each tray in the series is shaped to where the teeth should be a fraction of a millimeter from now, so wearing it applies gentle pressure in that direction. Change to the next tray each week and the teeth follow the sequence.
Invisalign is the best-known brand; there are several others, and the mechanism is the same across all of them. What differs between systems is the planning software, the plastic, and how much clinical data sits behind the movements they claim to achieve.
Small tooth-colored attachments are bonded to some teeth. They are not decoration: a tray can push a tooth easily but struggles to pull or rotate one, and an attachment gives the plastic something to grip so it can. A plan with no attachments on a case that needs them is a plan that will not finish.
The trays are made from a digital scan and a treatment plan the orthodontist designs and adjusts, tooth by tooth, before anything is manufactured. That planning stage is where the outcome is decided, and it is the part a patient never sees.
- Each tray is worn about twenty-two hours a day for roughly a week, then replaced by the next. Out for meals, out for drinks other than water, in for everything else including sleep.
- Elastics can be run from aligners using small hooks or cut-outs, so changing the relationship between the two jaws is not off the table — a common misconception is that aligners only straighten teeth within an arch.
- Slight reduction of enamel between contacting teeth creates room where crowding needs a millimeter or two. It is done in fractions of a millimeter, is painless, and is how many cases avoid extractions.
- Progress is checked against the plan at appointments every eight to twelve weeks. Where teeth have not tracked as designed, a new scan and a short series of refinement trays finish the job — that is normal, not a failure.
Who are clear aligners right for?
A good fit for
- Mild to moderate crowding, and spacing — closing gaps is among the most predictable things aligners do.
- Adults who would not start treatment at all if it meant visible brackets. The best appliance is the one a patient will actually complete.
- Anyone whose work involves presenting or being photographed, where brackets are a genuine professional problem rather than a preference.
- Patients with a history of gum disease under control, since brushing and flossing normal teeth is far easier than cleaning around brackets.
- Musicians who play a wind instrument, where brackets change embouchure for weeks.
- Mild relapse after previous orthodontic treatment, which is often a short and straightforward course.
Not the right answer if
- Anyone who will not wear them twenty-two hours a day. This is the whole thing. Trays in a pocket move no teeth, and a case worn sixteen hours a day does not finish late — it stops tracking and has to be restarted. If you already suspect you would not manage it, braces will give you a better result.
- Severe crowding, canines blocked out of the arch, and badly rotated teeth. Aligners cannot generate the control those need, and a plan that claims otherwise should prompt a second opinion.
- Cases needing significant extraction space closed. Closing a premolar space precisely is fixed-appliance work.
- Large skeletal discrepancies. A tray does not move a jaw. Where the problem is jaw position rather than tooth position, aligners produce a cosmetic result on an uncorrected foundation — see the underbite and open bite pages for what that means.
- Teenagers who lose things. That is not a judgement, it is a cost: a replacement tray takes time to make and the teeth drift back while you wait. Some teenagers are ideal aligner patients and some are not, and it is worth being honest at the consultation about which yours is.
- A patient who wants no responsibility for the outcome. Braces put the control with the orthodontist; aligners share it with you.
What do clear aligners cost?
Orthodontic fees are quoted per case rather than per condition, because two people with the same diagnosis can need very different treatment. These are the factors that move the number up or down, so you know what you are being quoted on:
- How many trays the plan needs, which tracks the amount of movement rather than the number of teeth.
- Comprehensive treatment of both arches versus limited treatment of the front teeth.
- Whether refinement trays are needed at the end — often they are, and whether they are included differs between practices, so ask.
- Attachments, elastics, and any enamel reduction the plan calls for.
- Your orthodontic insurance benefit, usually a lifetime maximum, and whether a flexible spending account applies.
- Retainers, which are part of the treatment and not an extra, and which matter more here because spacing reopens readily.
Ask for the fee, the payment schedule, and your insurance benefit in writing at the consultation, before you decide anything. Any orthodontic practice should give you all three without being pressed.
How long do clear aligners take?
Simple cases finish in six to twelve months. Moderate comprehensive treatment usually runs twelve to twenty-four, with appointments every eight to twelve weeks. A retainer follows, indefinitely.
What moves that estimate
- Wear time. Nothing else on this list comes close. The plan assumes twenty-two hours a day and every hour short of that is a day the teeth did not move.
- How far the teeth have to travel, which is set by the diagnosis rather than the appliance.
- Whether refinement trays are needed, which adds a few weeks to a few months and is common.
- Lost or damaged trays, since the teeth drift while a replacement is made.
- Whether elastics are part of the plan, and whether they are worn as directed.
What happens, from the first visit to the last?
Consultation
An examination and an honest answer about whether aligners can do what you want. Some cases are better served by braces, and you should hear that here rather than discover it eighteen months in.
Records and scan
Photographs, radiographs, and a digital scan of both arches. The scan becomes the model the whole plan is designed on.
Planning
The orthodontist designs the sequence tooth by tooth — which moves happen in which order, where attachments go, where enamel reduction is needed. Manufacturing happens after that is right, and it takes a few weeks.
First fitting
Attachments are bonded, the first trays are fitted and checked, and you are shown how to seat and remove them properly.
Wearing the series
A new tray each week at home, with appointments every eight to twelve weeks to check the teeth are tracking the plan.
Refinement
A fresh scan and a short additional series to finish the detail where teeth did not track exactly. Common, expected, and worth asking whether it is included in the fee.
Retention
A fixed wire behind the front teeth, a removable retainer, or both, indefinitely. Closed spaces in particular reopen without retention, so this is part of the treatment rather than the end of it.
Clear aligners or metal braces?
The honest version of this comparison is not which is better but what each is good at, and how much of the outcome depends on you.
| Clear aligners | Metal braces | |
|---|---|---|
| What it can correct | Mild to moderate crowding, spacing and bite problems, very well | Everything, including severe crowding and blocked canines |
| Depends on the patient | Twenty-two hours a day, every day. This is the main risk to the outcome | Elastic wear only. The appliance works regardless |
| Visibility | Close to invisible at conversational distance | Visible; ceramic brackets reduce it |
| Eating | No restrictions at all — the trays come out | A real list of foods to avoid for the whole treatment |
| Cleaning | Easier. You brush and floss normal teeth | Harder, and it matters more |
| Appointments | Every eight to twelve weeks, tray changes done at home | Every six to ten weeks, plus unplanned visits for repairs |
| Predictability | High in suitable cases, and dependent on wear in all of them | Highest — the orthodontist keeps control of every movement |
What is living with aligners actually like?
- Twenty-two hours a day is about two hours out. That covers a meal and brushing, and it does not cover grazing through the afternoon or a long dinner with wine. This is the honest constraint of the treatment and it is worth thinking about before choosing it.
- Water in the trays is fine. Anything else is not — coffee and tea stain them, and sugary or acidic drinks sit against the enamel with nowhere to go, which causes decay in a pattern orthodontists recognize on sight.
- Brush before the trays go back in, every time. Carrying a small brush is the habit that makes this workable.
- A slight lisp for the first few days is normal and almost everyone loses it. Tenderness for a day or two with each new tray, less as the series goes on.
- Keep the previous tray until the next one has settled. If a tray is lost, going back one step holds the position while a replacement is made — call the office rather than skipping ahead.
- Never store a tray in a napkin. The single most common way they are lost is being thrown away at a restaurant, and the case exists for that reason.
Why have it done here?
- The plan is designed by an orthodontist, tooth by tooth, rather than accepted as the software proposes it. That planning stage is where the result is decided.
- Dr. Kaplan completed an orthodontic residency and a Master’s at Loma Linda University, and treats aligner cases and fixed-appliance cases in the same practice — so the recommendation is not constrained by which one is on offer.
- You are told when aligners are the wrong tool for your case, and shown the measurements behind that. A treatment plan that fits the appliance rather than the problem is how aligner cases go wrong.
Questions patients ask about clear aligners
Do clear aligners work as well as braces?
For mild to moderate problems in someone who wears them twenty-two hours a day, yes. For severe crowding, blocked-out canines, or cases needing extraction space closed, braces do things aligners cannot. The examination and the records decide which category your case is in.
How many hours a day do I really have to wear them?
Twenty-two, which leaves about two hours for meals and brushing. This is not padding — the plan assumes it, and consistently wearing them less means the teeth stop tracking and the series has to be restarted from a new scan.
Are clear aligners more expensive than braces?
Not necessarily; the two are often close, and the fee tracks how much movement the case needs rather than the appliance. Ask specifically whether refinement trays and retainers are included, because that is where quoted prices differ most between practices.
Can I get clear aligners without seeing an orthodontist?
Mail-order aligners exist. They skip the examination, the radiographs, and in-person supervision — which is where undiagnosed gum disease, root problems and unsuitable cases get caught. Moving teeth is a medical procedure, and the savings are real but so is the risk.
Will the attachments show?
They are tooth-colored and small, and most people do not notice them. They are also what makes the trays able to rotate and pull teeth rather than only push them, so a plan without them on a case that needs them is a worse trade than their visibility.
Do aligners fix an overbite or an underbite?
Mild to moderate ones, yes, often with elastics run from the trays. Large skeletal discrepancies are a different problem — no removable tray moves a jaw. The overbite and underbite pages set out where that line falls.
What happens if I lose a tray?
Go back to the previous tray to hold the position and call the office. Do not skip ahead to the next one: it is shaped for teeth that have not moved yet and it will not seat, which risks the whole sequence.
