If you are an adult in Lincoln thinking about straightening your teeth, you have probably weighed the same trade-off everyone does: braces work, but they are fixed to your teeth around the clock. Clear aligners are removable, nearly invisible trays that gradually move teeth — and a 2026 systematic review and meta-analysis asked whether that difference shows up in measurable ways, from gum health to day-to-day comfort. Here is what the research found, in plain language, and what it means if you are considering treatment.
What the 2026 Review Did
Researchers led by Kaur and colleagues gathered studies comparing clear aligners with fixed braces, searching the scientific literature through March 2025. They reviewed 32 studies in total and pooled 28 of them in a meta-analysis — a statistical technique that combines results across studies to get a clearer overall picture. The review looked at gum-health measures (plaque, gum inflammation, and the depth of the pockets around teeth), pain in the early days of treatment, and quality of life at one week, one month, and the end of treatment.
Gum Health: The Aligners’ Clearest Advantage
The review’s strongest pattern was in gum health. Because aligners are removable, patients can brush and floss normally — no brackets and wires trapping food and plaque. The pooled results favored clear aligners on all three gum measures: plaque index by a mean difference of -0.437, gingival (gum inflammation) index by -0.233, and probing depth by -0.332. In plain terms, aligner patients in these studies tended to have cleaner teeth, less inflamed gums, and shallower gum pockets than brace patients.
That matters beyond fresh breath. Gum inflammation left unchecked can progress to gum disease, which damages the bone supporting teeth. For adults — who are more likely than teenagers to already have some gum recession or early gum disease — easier cleaning during orthodontics is a real, practical benefit, not just a cosmetic one. A prosthodontist in Roseville can assess your gum health before any orthodontic plan begins, since healthy gums are the foundation any tooth movement depends on.
Pain and Quality of Life
The review also found that clear aligner patients reported less pain in the early phase of treatment, with a standardized mean difference of -0.419 compared with fixed braces. Braces are typically tightened at appointments and can cause soreness and mouth irritation from brackets and wires; aligners can also cause pressure when a new tray starts, but the pooled evidence suggests the early discomfort tends to be milder.
Quality of life — a measure of how much treatment interferes with eating, speaking, appearance, and daily comfort — favored aligners at one week, one month, and the end of treatment. That fits the everyday experience: aligners come out for meals and brushing, are hard to see, and do not cut the inside of the cheek the way a loose wire can.
The Catch: Aligners Only Work If You Wear Them
Here is the honest counterweight to all of the above. Braces work around the clock because they cannot be removed. Aligners work only during the hours they are actually on your teeth. The review’s benefits assume patients wore their aligners as directed, and real life — work lunches, coffee, long dinners — is full of reasons to leave trays out. If aligners spend too much time in their case, treatment slows, results fall short, and the gum-health advantage narrows.
Aligners also cannot fix every problem. Severe bite issues, large rotations, or teeth that need significant vertical movement may still be better served by braces or a combined plan. A candid consultation should tell you whether you are a good aligner candidate or whether braces would get you a better result, even if they are less convenient.
Clear Aligners at Expert Dental Group
Expert Dental Group offers clear aligner therapy for adults, and Dr. Leila Nikpour is a prosthodontist with more than 15 years of dentistry experience. To be clear about a common point of confusion: the practice is a clear aligner therapy provider, not an Invisalign provider — “Invisalign” appears here only because many patients search for it when they mean clear aligners generally. Your plan, your trays, and your follow-up are managed in-house, with checkups to track progress and gum health along the way.
If you are considering treatment, ask how long your case is expected to take, how many hours a day you will need to wear the trays, what happens if a tray is lost, and how your gum health will be monitored during treatment. The answers will tell you whether aligners fit your life — and your life is what determines whether they work.

Frequently Asked Questions
Are clear aligners really better for gum health than braces?
In the 2026 review, yes: aligner patients had less plaque, less gum inflammation, and shallower gum pockets than brace patients, largely because removable trays let patients brush and floss normally. Good hygiene still matters — aligners do not clean your teeth for you.
Do clear aligners hurt less than braces?
The review found less early pain with aligners than with fixed braces. New trays can still cause pressure for a day or two, but there are no brackets or wires to irritate the cheeks and lips.
How many hours a day do I need to wear aligners?
Your clinician will give you a specific wear schedule, and following it closely is what makes treatment work. Aligners left out for long stretches slow progress and can compromise the final result.
Can aligners fix every orthodontic problem?
No. Mild to moderate crowding, spacing, and bite issues often respond well, but severe bite problems or complex tooth movements may need braces or a combined approach. A consultation determines candidacy.
Is Expert Dental Group an Invisalign provider?
No. The practice provides clear aligner therapy but is not an Invisalign provider. “Invisalign” is mentioned only because many patients search for it when looking for clear aligner treatment.
