Is Invisalign better than other clear aligners?

Not automatically. It is the most established system and the one most patients ask for, but the right choice depends on the movements you need. Our general aligner guide sets out how to compare them.

How many hours a day do I have to wear them?

Roughly 20 to 22 hours. Out for eating and for brushing, in for everything else. A plan that is not worn does not progress, and the trays will not fit later ones.

Can I have aligners if I have crowns or veneers?

Often yes, but the plan has to be designed around them — the shape of a crowned tooth is different from a natural one, and the trays are made to suit what is actually in your mouth.

What stops my teeth moving back?

A retention plan helps maintain alignment. Your clinician may recommend removable retainers, a bonded wire or a combination based on your bite, oral health and ability to maintain them.

Invisalign Clear Aligners

The best-known clear aligner system: removable trays made from a single digital plan, with a simulated result shown before you commit.

Invisalign is the name most people reach for when they ask about clear aligners. The trays are made from one digital treatment plan rather than a series of guesses, and a simulation of the likely result can be reviewed before anything starts.

What it is, and why you might discuss it

A series of clear, custom-made plastic trays, each worn for one to two weeks, moving the teeth a small amount at a time until the plan is complete.
The plan is designed from a digital scan and photographs of your teeth, and a simulated outcome can be shown beforehand — so you are approving an intended result, not a promise.
Small tooth-colored bumps called attachments are bonded to certain teeth so a tray can grip and produce particular movements.
It is one clear aligner system among several. The differences between systems mostly come down to the movements you need, the timeline and the price — which is why our general clear aligner guide is worth reading alongside this one.

How we assess whether it suits you

A scan, photographs, X-rays and an examination of the bite. Some movements are difficult with aligners alone, and some bites are better served by fixed appliances or a different approach.
The gums need to be healthy and any decay treated before trays are worn; moving teeth through inflamed gums causes avoidable damage.
Existing crowns, veneers or bonded teeth change how a plan is designed — the trays have to be built around them.
Whether the plan is designed and supervised in the practice, and what happens if the teeth do not track the trays, is explained before you agree to anything.

What the process involves

01Digital scan, photographs and a bite record — no impression material.
02A simulated plan is reviewed with you: the intended movements, the likely finish, and how long the plan runs.
03Trays are manufactured for the whole plan; any attachments are bonded at the fitting appointment.
04Trays are changed at home on schedule, reviewed at intervals to confirm the teeth are tracking, and finished with a retainer.

Alternatives worth asking about

Clear aligner therapy, generally
The same idea without a brand — useful for comparing systems on movement, timeline and cost.
Porcelain veneers
Where the issue is shape and proportion rather than position, and the teeth are being altered anyway.
Cosmetic bonding
Closes small gaps and evens edges in a visit, without moving anything.

Benefits

Nearly invisible in the mouth, with no wires or brackets against the cheeks.
Removable for eating and for brushing and flossing as normal.
A simulated result can be seen before treatment is agreed.
No conventional wires or brackets; however, trays can break and bonded attachments can detach and need review.
The digital plan means the intended finish is documented from the start.

Risks

Results depend on prescribed wear, case complexity, biological response and clinical monitoring; extra trays or changes to the plan may be needed.
Trays can be lost, cracked or warped, which delays the plan.
Some movements take longer than the simulation suggests, or need extra trays.
Without a retainer afterward, teeth drift back toward where they started.

Limitations

Must be worn roughly 20 to 22 hours a day for the plan to work.
Not suitable for every bite problem — some cases need a different appliance or a combined approach.
Aligners move teeth, not jaws; a skeletal mismatch is not corrected by trays.
The final result can differ from the simulation, which is a preview of intent rather than a guarantee.

Timing

Treatment commonly runs from several months to a little over a year, depending on the plan. Your simulated plan states the intended duration before you agree to it.

Recovery

There is no recovery period. New trays can feel tight for a day or two and speech may take a short time to adjust.

What affects the cost

These factors explain the scope of care, not a Whole Tooth price quote. Assessment fees are separate from later treatment estimates. Whole Tooth’s fees and disclosure policy require confirmation; ask about applicable assessment charges before arranging a visit.
