How Invisalign Works, Start to Finish

Invisalign moves teeth with a numbered series of clear plastic aligners, each one shaped slightly differently from your current bite. The plastic pushes, the bone remodels, the tooth moves a fraction of a millimeter, and you switch to the next aligner. It works well, and it works only while the aligners are actually in your mouth. Here is the whole process, start to finish, at our Midtown Houston office.

What Is Actually Happening to Your Teeth

A tooth is not cemented into your jaw. It sits in a socket, suspended by a periodontal ligament, and it can move.

When an aligner applies gentle pressure to one side of a tooth, the bone on that side is resorbed by cells called osteoclasts, and new bone is laid down on the opposite side by osteoblasts. The tooth migrates into the space created. This is the same biology braces use. The delivery system is what differs.

Each aligner is designed to produce roughly a quarter of a millimeter of movement. Twenty aligners is about five millimeters. That is why the number of aligners tells you more about your case than the number of months does.

Most cases also need attachments: small tooth colored bumps bonded to certain teeth so the smooth plastic has something to grip. Without them, an aligner tends to tip a tooth rather than move it properly. If someone offers you Invisalign with no attachments on a case that needs rotation, ask why.

From Consultation to Your First Aligner

The consultation is free. We take photographs, X rays and a digital scan of your teeth, which takes a few minutes and replaces the impression trays you may remember.

That scan goes into the planning software, where your orthodontist maps out where every tooth has to end up and in what order. This is the part that determines your result, and it is not automated. The software proposes, the orthodontist decides.

You see the projected outcome before you agree to anything.

The aligners are manufactured and arrive in two to three weeks. At the fitting appointment we bond the attachments, seat your first aligner, check it, and show you how to insert and remove them without stressing the plastic.

From that day, the work is yours.

The Wear Time Rule, and Why It Is Not Negotiable

Twenty to twenty two hours a day. Out for meals, out for anything other than water, out to brush. In for everything else, including sleep.

That leaves roughly two hours of eating and cleaning time in a day, which sounds tight until you realize how much of it is spent with the aligners sitting on a napkin while you keep talking.

What happens at 14 or 16 hours a day is not that treatment slows down proportionally. The aligners stop tracking. A gap opens between the plastic and the biting edge of a tooth, the next aligner does not seat properly, and you end up going backward or needing a new scan and a new set. That is where an 18 month case becomes a 30 month case.

The practical fixes are boring and they work: put them back in immediately after eating, carry the case everywhere, and change aligners at bedtime rather than in the morning so the tightest hours pass while you are asleep.

What Each Month Looks Like

You change to the next aligner every one to two weeks, at home, on the schedule you are given.

The first day or two in a new aligner feels tight and the teeth are tender. That pressure is the treatment working. It settles within 48 hours.

You come in every six to ten weeks so we can check the aligners are seating fully and the teeth are where the plan says they should be. These visits are short and there is nothing to tighten.

Speech: many patients have a slight lisp for the first few days. Reading out loud speeds up the adjustment. It resolves for most people.

Cleaning: rinse them in cool water and brush them gently with a soft brush. Hot water warps them permanently, so no dishwasher and no boiling. Aligner cleaning crystals exist and are cheap. We do not recommend household chemical soaks.

And brush before putting them back in. Sealing sugar against your enamel for 22 hours a day is how a straightening case turns into a case with cavities.

What Invisalign Can and Cannot Do

Handles well: crowding, spacing, relapse after childhood braces, mild to moderate bite correction, and teeth that need to be tipped or rotated modestly.

Harder or outside range: severe rotations, especially on round teeth like premolars; moving a tooth a long way vertically, whether extruding or intruding; large skeletal discrepancies where the jaws rather than the teeth are the problem; and complex cases needing extractions.

Some of those become possible with attachments, elastics and a skilled plan. Some do not, and braces are the better mechanics.

The claim that clear aligners can treat any case is marketing. Your orthodontist looking at your scan is how you find out where your case sits.

What It Costs in Houston

Ask about the average cost of Invisalign in Houston and you will get a wide spread of answers, because quotes are structured differently across the city. At Omega Dental Specialists, Invisalign is one fee, quoted in writing after the exam and the scan. Traditional braces are the value option here; Invisalign costs more, in line with ceramic braces, because both are the discreet route. What moves the fee is your case, meaning how far the teeth have to move and how many aligners that takes. Retainers after treatment carry their own fee, quoted up front.

Orthodontic insurance benefits sit apart from your general dental benefit. They usually have their own lifetime maximum rather than an annual one, and many plans include an age cutoff. We verify your specific orthodontic benefit with your insurer before you start and give you your share in writing rather than quoting a typical contribution that may have nothing to do with your plan.

FSA and HSA dollars cover orthodontics, which is how many of our adult patients pay.

Cherry, Affirm and Sunbit split the balance into monthly payments. For today's exact fee, call (713) 322-7474.

Retainers, and What Holds the Result

When the last aligner comes out, the teeth are in position but the bone around them is still settling. Left alone, they drift back, and the pull is strongest during the first year.

Retainers carry their own fee, quoted up front. Full time at first, then nights indefinitely.

This is the step that decides whether you are still happy in five years. A large share of the adults who come to us about teeth shifting had orthodontic treatment as teenagers and stopped wearing their retainer.

If you lose one, replace it quickly. A retainer that no longer fits is telling you the teeth have already moved.

Starting Treatment in Midtown Houston

Our orthodontist is Dr. Bernard Boback, Harvard trained. Orthodontics is his specialty rather than an added service, which matters most on the cases sitting at the edge of what aligners can do.

The consultation is free and includes the scan and X rays. You will see the plan, the number of aligners, the timeline and the fee before deciding anything. If we think braces would give you a better result, we will say so.

We are at 106 W Gray St in Midtown, minutes from Montrose, River Oaks, Downtown, the Museum District and the Texas Medical Center, with Saturday appointments for people who cannot get away midweek.

Common Questions

Frequently asked

How does Invisalign move teeth?

Each aligner is shaped slightly differently from your current tooth positions, so it applies gentle continuous pressure. Bone on the pressure side is resorbed and new bone forms on the opposite side, letting the tooth migrate about a quarter of a millimeter per aligner. It is the same biological process braces use, delivered by plastic instead of brackets and wire. Small bonded attachments give the aligner grip for harder movements.

How many hours a day do you have to wear Invisalign?

Twenty to twenty two hours a day. They come out for meals, for anything other than water, and for brushing, and go back in immediately afterward. Below about 20 hours the aligners stop tracking, meaning gaps open between the plastic and the teeth, the next aligner will not seat, and treatment either stalls or needs a new scan and a new set of aligners.

How much does Invisalign cost in Houston?

The average cost of Invisalign in Houston varies widely because quotes are structured differently from practice to practice. At Omega Dental Specialists in Midtown Houston it is one fee, quoted in writing after a free consultation with a scan and X rays; traditional braces are the value option here and Invisalign costs more as the discreet route. We verify your orthodontic insurance benefit with your insurer before you start and give you your out of pocket share in writing. Cherry, Affirm and Sunbit split the balance into monthly payments. Call (713) 322-7474 for today's fee.

Does Invisalign hurt?

The first day or two in each new aligner feels tight and the teeth are tender, which is the pressure that produces the movement. It generally settles within 48 hours and most patients need nothing stronger than ibuprofen, if that. Changing aligners at bedtime rather than in the morning means the tightest hours pass while you are asleep.

How long does Invisalign take?

Typically 12 to 24 months, though minor cases finish sooner and complex ones run longer. The number of aligners tells you more than the number of months, since each one produces about a quarter of a millimeter of movement. Your actual timeline depends heavily on wear time: aligners worn less than 20 hours a day extend treatment considerably rather than slightly.

Can Invisalign fix any orthodontic problem?

No, and any claim that it can is marketing. It handles crowding, spacing, relapse after childhood braces and mild to moderate bite correction well. Severe rotations, moving teeth a long way vertically, large skeletal discrepancies where the jaws are the problem, and cases requiring extractions may need braces. An exam with X rays and a scan answers it for your case.

How do you clean Invisalign aligners?

Rinse them in cool water every time they come out and brush them gently with a soft toothbrush. Never use hot water, a dishwasher or boiling water, all of which warp the plastic permanently and ruin the fit. Aligner cleaning crystals are inexpensive and effective. Brush your teeth before putting the aligners back in, because sealing sugar against enamel for 22 hours a day causes cavities.
