Things People Often Get Wrong About Clear Aligners

Clear aligners have become one of the most popular ways to straighten teeth especially for adults who want a discreet option. But because they’re everywhere on social media, a lot of people start treatment with the wrong expectations. Here are the most common things people often get wrong about clear aligners and what to know before you begin.

Myth vs Fact

The chart gives you the fast answers, but real life is a little more nuanced. Below, we’ll unpack the biggest areas where people get confused—how aligners compare to braces, who they work best for, what “normal” discomfort feels like, and why follow-ups and retainers matter—so you can feel confident before starting.

1) Clear aligners are only for minor fixes

Clear aligners can handle a wide range of concerns—crowding, spacing, some bite issues, and more. The key is case selection and planning. Some smiles are great aligners cases. Others may need braces, a combination approach, or additional dental work first. A consultation is the best way to know what’s realistic for your teeth.

2) Clear aligners work even if you don’t wear them much

Aligners are not a “wear when you remember” treatment. They work through steady, consistent pressure—so skipping hours (or days) can slow your progress and cause tracking issues (when teeth don’t match the aligner shape). If you want predictable results, aligners should be worn as directed and removed only for eating/drinking (except water) and brushing/flossing.

3) All clear aligners are the same

Not all aligner treatment is the same. One of the biggest differences is professional supervision. A clinician monitors movement, checks gum and bone health, and can make adjustments if teeth aren’t tracking. That oversight is a big deal, especially for bite changes and long-term stability.

4) Aligners shouldn’t feel tight or sore

A little tightness when you start a new tray is common. Most people notice it fading after the first day or two. What’s not normal: sharp pain, bleeding, or aligners that consistently don’t fit. If something feels “off,” it’s worth checking in so small problems don’t become big delays.

5) Attachments mean something went wrong

Attachments (small tooth-colored bumps) are often used to help aligners grip and guide tooth movement more precisely. They’re common and can make treatment more accurate—not less. Think of them as tiny handles that help your aligners do their job better.

6) You can eat or sip anything with aligners in

Eating with aligners can crack them, stain them, or trap sugar/acid against your teeth. A simple rule: remove aligners for meals and anything besides water. If you do drink coffee or something sweet, rinse with water and brush before putting aligners back in when possible.

7) Once you finish, you’re done forever

The real secret to long-term results is retention. Teeth naturally want to shift, especially after orthodontic treatment. Retainers aren’t optional if you want your new smile to stay put. Wearing your retainers as directed protects the time and money you invested.

8) Clear aligners are just cosmetic

Straighter teeth can look great, but alignment can also make brushing and flossing easier, reduce areas where plaque hides, and support healthier gums. For many people, it’s both cosmetic and functional.

A confident smile isn’t one-size-fits-all—sometimes the answer is clear aligners, and sometimes a small cosmetic touch makes the biggest difference. At Posh Pearl, we help you compare your options based on your goals, your bite, and what will look most natural long-term.
