Invisalign in Burlington

Summary– Wearing Invisalign aligners consistently is key to getting results on time. This blog explains how many hours a day you should wear them, what happens if you don’t, and how it affects your progress and cost. If you’re considering Invisalign in Burlington, or Nashua, this guide helps you stay on track.

 

The Truth About Taking Your Aligners Out

Wearing Invisalign for less than 20 hours a day can slow down your results by weeks—or even months? That’s right. The success of your Invisalign treatment depends heavily on how long you wear the aligners each day.

Patients often ask, “Can I take them out for a few hours?” or “Is it okay to skip them at night?” Let’s clear things up. If you’re considering Invisalign in Nashua and Burlington, understanding the wear time is key to getting the results you want, on time.

 

The Magic Number: 20 to 22 Hours a Day

Invisalign aligners are designed to apply gentle pressure to your teeth throughout the day. That pressure only works if the trays stay in place for at least 20 to 22 hours every single day.

Taking them out too often, especially for long periods, can delay your progress. In some cases, it might cause your teeth to shift back slightly. That means more time in treatment and possibly extra aligners, which could also affect your Invisalign treatment cost.

 

When to Remove Your Aligners

The good news is you can remove Invisalign trays when you eat or brush your teeth. That’s one of the reasons people love this treatment. But once you’re done, they need to go back in right away.

For example, if you eat three meals and brush twice a day, those are the only times you should remove them. Everything else—working, reading, watching TV, or even sleeping—should be spent wearing your aligners.

What Happens If You Don’t Wear Them Enough

If you consistently wear the aligners for less than 20 hours a day, a few things can happen. Your teeth may not move as planned. Each new tray might feel tighter or more painful because your teeth haven’t kept up.

That could lead to needing extra trays or a longer treatment time. This also means your total Invisalign treatment cost could increase if additional adjustments or refinements are needed.

It’s also frustrating. You might start out excited about Invisalign in Nashua, NH, but if results stall, it can be discouraging. That’s why consistency is everything.

 

How to Stay on Track

Making a habit of putting your trays back in right after meals can make a big difference. Setting reminders on your phone or using a tracking app also helps. Some patients find it useful to carry their case at all times so the aligners don’t get lost or forgotten.

If you’re new to Invisalign in Burlington, your provider will likely stress how important wear time is right from the start. It’s the most important part of making Invisalign work properly.

How Long Will You Wear Invisalign Overall?

The full length of treatment varies depending on your case. Most people wear Invisalign for 12 to 18 months. However, the more consistent you are, the more likely you’ll stay on schedule, or even finish early.

Skipping days or removing the trays for too long can easily push you past your original timeline. That’s another reason why tracking your hours helps, so you don’t accidentally fall behind.
