Why Clear Aligners

Straighter Teeth Without Brackets and Wires

Clear aligners are thin, custom trays that move your teeth a small, planned amount with each new set. Most people around you will not notice them, and you take them out to eat, brush and floss.

Straight teeth are also easier to keep clean. Overlapping teeth leave tight corners where plaque builds up, and an uneven bite wears some teeth faster than others.

  • Nearly invisible trays instead of metal brackets
  • Removed for meals, so there are no food restrictions
  • Brush and floss your teeth the way you always have
  • No wires to tighten or brackets to break
  • Each set designed from a 3D scan, not putty impressions
  • Works for teens and adults whose teeth have shifted
What Aligners Correct

Crooked Teeth Clear Aligners Can Fix

Clear aligners handle most of the alignment problems we see. Your scan and exam confirm whether they suit your teeth.

01

Crowding

When there is not enough room, teeth overlap and twist. Aligners create space step by step and line them back up.

02

Gaps Between Teeth

Spaces between the front teeth close gradually as each set of trays draws the teeth together.

03

Rotated Teeth

Small attachments bonded to a tooth give the tray something to grip, so it can turn a rotated tooth into line.

04

Overbite and Underbite

Many bite problems where the upper and lower teeth do not meet evenly can be improved with aligners.

05

Crossbite

When some upper teeth sit inside the lower teeth, aligners can move them back so the bite closes properly.

06

Shifting After Braces

Teeth that moved back after braces, often the lower front teeth, can be straightened again without brackets.

Technology

Planned on 3D Scans, Not Guesswork

Moving teeth safely means knowing the roots, the bone and the bite, not only what shows when you smile. These are the tools we use to plan and follow your aligner case.

iTero Element Scanner

A digital 3D scan of your teeth replaces putty impressions and becomes the blueprint for every set of trays.

Vatech CT Scan

3D imaging shows root position and bone support before any tooth is moved.

TENS and K7

Measures jaw muscle activity and how your teeth meet, so the new alignment suits your bite.

Progress Check-Ins

Visits about every six weeks let Dr. Silva confirm your teeth are tracking with each new set of trays.

What to Expect

Your Clear Aligner Treatment, Step by Step

  1. Consultation and 3D Scan

    We review your dental and medical history, check your teeth, gums and bite, then take an iTero scan.

  2. Your Custom Plan

    Dr. Silva maps how each tooth will move and goes over the time frame, cost and payment options with you.

  3. Wearing Your Aligners

    You switch to a new set of trays about every two weeks and come in for a progress check about every six weeks.

  4. Keeping It Straight

    Teeth try to drift back, so a retainer and regular cleanings protect the result for the long term.

FAQ

Clear Aligner Questions, Answered

How long does clear aligner treatment take?

Most cases take 6 to 18 months. Each set of aligners is worn for about two weeks, and the total depends on how far your teeth need to move. Your iTero scan gives you a time frame before you start.

How much do clear aligners cost?

It depends on how complex your case is and how many sets of trays you need. We give you the exact cost after your consultation and scan, check your orthodontic benefits, and offer payment plans and a dental savings plan.

How many hours a day do I wear them?

Plan on wearing your aligners most of the day and night, taking them out only to eat, drink anything other than water, and brush. Put them back in soon after meals so your teeth keep moving on schedule.

Do clear aligners hurt?

Most people feel pressure or mild soreness for a day or two when they switch to a new set. That is a sign the trays are working, and it eases quickly.

Will aligners change the way I talk?

Some people notice a slight lisp for the first few days while the tongue adjusts. It usually fades quickly. Read more in our article on how clear aligners affect speech.

Am I too old for clear aligners?

There is no upper age limit for moving teeth. What matters is that the gums and supporting bone are healthy. If they need attention first, our periodontist, Dr. Michael Strassberg, can treat them through our periodontics care before straightening begins.

Are clear aligners right for every crooked tooth?

Not always. Very slightly uneven front teeth may look better with veneers, and severe crowding or mismatched jaws may need orthodontic or surgical care. See all the ways we treat crooked teeth; your exam shows which option fits.
