Invisalign & Clear Aligners
Your schedule doesn't have to change while you straighten your teeth. A series of custom-made, clear aligner trays shifts them gently into place, so there are no brackets, no wires, and none of the look of traditional braces. Wear them and most people will never notice. Dr. Najjar plans your Invisalign treatment at NuLine Orthodontics with advanced digital imaging, which means you can preview your new smile on screen before day one.
What they are
Clear plastic alignment trays, custom-made to your teeth, that shift them gradually toward the desired position. A new set follows every few weeks as the teeth move.
Who they're for
Teens and adults with mild to moderate crowding, spacing, or bite issues who are looking for a discreet, removable alternative to traditional metal braces.
How we help
Aligners custom-designed for precise tooth movement, digital treatment planning that lets you preview your results up front, and regular progress check-ins with Dr. Najjar.
Straightening teeth no longer means metal. Ask if Invisalign is a fit for you.
Straightening your teeth changes more than your reflection. It changes how comfortable you feel in a meeting, a classroom, or a photo. Adults often come to us wanting that confidence for work and social life. Teens usually arrive looking for something more modern than metal brackets and wires. Either way, Dr. Najjar fits you with custom-designed alignment trays that move your teeth toward the desired position in small steps, and you swap in a fresh set every few weeks until your smile is perfectly aligned.
Invisalign can fit your budget too. Ask about our flexible financing options.
How Clear Aligners Work
- Consultation: Digital impressions and an exam by Dr. Najjar confirm whether clear aligners are right for you
- Custom design: Software maps out a series of aligners that move your teeth in precise increments
- Wear schedule: Each set stays in 20–22 hours a day for roughly 2 weeks
- Progress checks: Every 6–8 weeks you stop in briefly for new aligners and a look at your progress
- Results: Most cases run 12–18 months, often finishing sooner than traditional braces
Advantages of Invisalign
- Appearance: Friends, family, and coworkers may never spot them, because clear aligners are barely visible
- Comfort: Metal brackets and wires can rub against your cheeks and gums. Smooth plastic doesn't
- Removable: No food restrictions apply, since they come out for meals, brushing, and special occasions
- Better hygiene: No threading floss under wires, no working around brackets. You brush and floss the way you always have
- Faster treatment: Metal braces can run as long as 3 years, while many aligner cases wrap up in 12–18 months
- Predictable results: Before the first tray goes in, digital planning shows you the final smile
What Clear Aligners Can Correct
- Crowding: Teeth packed too tightly, overlapping one another
- Spacing: Teeth with gaps between them
- Overbite: The upper teeth come down too far over the lower ones
- Underbite: The lower teeth protrude past the upper ones
- Crossbite: Upper and lower teeth that don't line up properly when you bite
- When a case is more complex, traditional braces or lingual braces may be the better recommendation
Beautiful results in less time with clear aligners, and the only person who needs to know is you.
What to Expect at Your Visit
Visit Steps
- Consultation: Digital scans, a look at your bite, and a conversation about your goals with Dr. Najjar
- Treatment preview: A 3D simulation, built by advanced software, walks through how your teeth move at each stage
- Aligner delivery: You go home with your first sets of custom aligners and instructions for wearing them
- Progress visits: Quick check-ins every 6–8 weeks, far fewer than the adjustments traditional braces require
- Retainers: Custom retainers hold your new smile once treatment ends
Helpful Tips
- For best results, keep aligners in 20–22 hours a day, out only to eat and brush
- Move to the next set on schedule, even when the current one still feels comfortable
- A soft toothbrush and lukewarm water clean them daily. Skip hot water, which can warp the plastic
- That mild pressure from a new set is normal. It means your teeth are moving
- Whenever they're out of your mouth, put aligners in their case so they don't get lost or damaged
- Your previous set makes a useful backup if the current one goes missing
Frequently Asked Questions
The complexity of your alignment issues sets the pace. Most cases wrap up in 12 to 18 months, and simple ones can finish sooner. Dr. Najjar will put a timeline on your own case at the consultation.
The distance your teeth have to cover is the biggest variable, along with how much of the job is bite correction and how much is crowding and spacing. Wear time is the other one, because Invisalign only works while the aligners are in. The plan is built on 20–22 hours a day, and hours spent with a tray sitting in its case are hours the teeth are not moving.
Along the way you change to a fresh set roughly every 2 weeks and stop in for a progress check every 6–8 weeks. Those visits are short, and they are where we catch a tooth that is not tracking the way the plan predicted, while there is still time to adjust.
Most patients feel some mild pressure or tightness for a day or two each time they switch to a new set. That's normal, and it's a sign your teeth are moving. Compared with the soreness that follows a traditional braces tightening, it's generally much milder. Clear aligners have no brackets or wires either, so the rubbing against cheeks and gums that metal can cause is not part of the picture.
A few habits take the edge off the first days in a new tray:
- Change to the new set in the evening, so you sleep through the tightest hours.
- Stick to softer meals for a day or two after a change, while biting feels tender.
- Keep the aligners in. Taking them out for relief only restarts the pressure when they go back.
- Cold water with the trays in settles tender teeth.
- Press a new tray into place gently and evenly. Do not bite it down.
What is not normal is a sharp edge, a tray that will not seat properly, or discomfort that keeps building day after day. Call us if that happens, since it is usually something small we can smooth or check in a few minutes.
Yes! Aligners come out, so you can eat whatever you like. Take them out before you eat and brush before you put them back in. Traditional braces come with food restrictions; clear aligners don't.
The one rule that matters is that only water goes in your mouth while the trays are in. Coffee, tea, soda, wine, and juice can stain the plastic, and sugary or acidic drinks get held against your teeth by the aligner, which is exactly where you don't want them sitting. Chewing with trays in can crack or distort them as well.
The rest comes down to timing, and wear hours disappear quietly there. A long lunch, a coffee break, and an afternoon snack can add up to far more time out than you intended, so the habit worth building is putting the aligners straight back in the moment you have finished.
Unless you point them out, most people won't notice. Clear aligners are nearly invisible, and that discretion is one of the biggest draws for adults and teens who would rather straighten their teeth quietly.
Keeping them that discreet is mostly about cleaning, and regular brushing keeps them clear. A quick rinse leaves film and stain behind, and so does putting a tray back in over unbrushed teeth. A cloudy aligner is far more noticeable than a clear one, and a gentle brush morning and night is enough to prevent it. Some treatment plans also use small tooth-colored attachments bonded to a few teeth to give the aligners something to grip, and while those are shaded to blend in with the tooth, they are not literally invisible, so Dr. Najjar will tell you up front whether your plan calls for any.
Speech is the other thing people ask about. A slight lisp is common in the first days while your tongue adjusts to the edge of the plastic, and reading aloud for a few minutes at a time helps it adapt faster.
Clear aligner treatment carries no upper age limit. Adults at any age can benefit from straighter teeth, and a good number of clear aligner patients are adults after a discreet way to improve their smile.
Your case decides it, not the number of years behind it. Adults tend to arrive for one of a few reasons: teeth that drifted after childhood braces once the retainer was quietly retired, crowding that has crept in over the years, or a smile they simply never got around to sorting out. Cases like those often sit well inside what clear aligners can do. Crowns, bridgework, or a history of gum treatment do not automatically rule treatment out, though they do shape the plan, since existing dental work can change where attachments sit and how the stages are sequenced, and Dr. Najjar goes through all of it before anything starts.
Discretion is part of why clear aligners suit adult schedules, and the progress visits are short enough to fit around a working week. Learn more about adult orthodontics.
Price tracks the complexity and length of your treatment, and clear aligners often land close to traditional braces. You'll get a detailed estimate at your consultation, along with flexible financing options intended to make treatment affordable.
That consultation is complimentary. What moves an aligner estimate is how many sets your plan calls for and how much correction each one has to deliver, so mild crowding and a case that has to change the way your teeth meet do not land in the same place.
Orthodontic coverage differs a good deal depending on the plan, both in how much it pays and in whether there is a lifetime cap, so we check your benefits before treatment begins and fold the answer into your estimate. Whatever your plan does not cover goes onto a schedule you set with our financial coordinator, arranged through us directly.
Custom retainers take over once your teeth reach their final positions, and they're usually worn at night. Skip them and teeth can gradually drift back toward where they started.
Needing one is not a sign that something went wrong. Teeth sit in bone that keeps remodeling around their new positions after the last aligner comes out, and the tissues holding them take time to settle. The retainer holds your result steady while that happens. Wear is often heavier at the start and eases into a nights-only routine, and we give you your own schedule when yours is made and check the fit at your follow-up visits.
Look after it the way you looked after your clear aligners and it should last. The routine carries straight over, with one difference worth knowing: the appliance spends most of the day out of your mouth, so the case earns its keep in a way it never quite did during treatment. See our retainers page to learn more.
