Aligner Maintenance: Reasons Why Your Aligners May Not Be Working

Inadequate Wear Time

A lot of people think that wearing aligners for a short period each day will do the job. But that's not the case. For the best results, you need to have them on for about 20 to 22 hours every single day.

Yes, it might seem a lot, but if you skip wearing them for the required hours, your teeth won't move to their correct positions as planned.

Now, how do you remember to wear them for so long? It's simple: just set a reminder on your phone to put them back in after you take them out. This way, you won't forget. Also, make it a daily routine, just like brushing your teeth.

Neglected Oral Hygiene

Using aligners isn't just about wearing them; it's also about taking good care of them to ensure they do their job right. One major point here is not to overlook your oral hygiene.

You see, if you don't clean your teeth well, bacteria and plaque can build up quickly, creating issues not just for your teeth but for the aligners too. But the good news is that keeping things clean isn't hard. You should continue with your regular brushing and flossing to keep your teeth healthy.

Besides this, your aligners also need cleaning to function correctly. You can use simple soap and clean water for that. You can also use special cleaning sprays, like Smilesaver, which promise to kill 99% of germs in just 30 seconds.

Using Expired Aligners

Wearing aligners past their expiry date is something you should avoid. Expired aligners are not as effective because they can't give the necessary pressure your teeth need to move to the correct places.

So, how do you prevent this? The answer is to follow the schedule your dentist gave you. They have mapped out exactly when you should switch to a new set of aligners. Doing this ensures that your treatment stays on the right path.

Ill-fitted Aligners

You might notice that your aligners don't fit your teeth properly. This could be because of wrong measurements or mistakes when they were made. It is vital to understand that aligners that don't fit can't do their job well; they can't guide your teeth to where they need to be.

But there's no need to worry too much, as this issue can be fixed. The first thing to do is to reach out to your dental care provider. Set up a meeting to discuss what can be done to get aligners that fit you perfectly. Acting fast can stop more delays in your treatment and get you back on track swiftly.

Diet Recommendations And Aligner Maintenance: Common Mistakes

Utilizing aligners for teeth straightening entails adhering to specific dietary guidelines outlined by your dentist. Usually, this means avoiding foods and beverages that can potentially damage your aligners, including hard, crunchy foods and drinks that are known to stain, like coffee and red wine.

Ignoring this advice could lead to changes in the shape or appearance of your aligners, making them less effective in their job. Respecting these recommendations safeguards your aligners, ensuring they can function optimally to deliver the desired results.

Ignoring Regular Dental Check-ups

Getting aligners is just one part of the journey to straight teeth; another crucial part is keeping up with your dental check-ups. It's at these check-ups that your dentist can really see how things are going and if any changes are needed.

So, if you're thinking about missing an appointment, you might want to reconsider. Regular visits to the dentist can help spot issues before they become bigger problems, saving you time in the long run. Plus, your dentist might have some advice or suggestions to help things go even more smoothly.

Unaddressed Dental Issues

Before you begin your journey with aligners, it is crucial to take care of any existing dental problems. Issues like cavities or gum diseases can really get in the way of your aligners working correctly.

To avoid this, make a plan with your dentist to address these problems beforehand. The objective is to start your aligner treatment with a healthy foundation. By doing this, you help to make sure your aligners can work effectively without any obstacles.

Non-compliance with Aligner Accessories

When you are using aligners, your dentist might recommend accessories like chewies or movement trays to aid in the process. These tools are designed to support the work of the aligners, helping them to be more effective in moving your teeth correctly.

It is a good idea to learn how to use these accessories properly. This means understanding not just how to use them but also when to use them. Following your dentist's instructions regarding these accessories can really help in getting the best results from your aligner treatment.

Inconsistent Use of New Aligners

Consistency includes regularly switching to new sets of aligners every few weeks as instructed by your dental care provider. Failing to do so can disrupt the straightening process, causing delays and potentially reducing the treatment's effectiveness.

Adhering to the set schedule is non-negotiable. The schedule is designed with the specific movements of your teeth in mind, and each set of aligners has a role in this progression.

Therefore, not moving to the new set on time can hinder this process. Ensure to mark your calendar or set reminders on your phone to change your aligners as scheduled.


Achieving the perfect smile with aligners requires diligence. Follow the advice of your dental care provider closely. Wear the aligners for the recommended hours daily and maintain good oral hygiene.

Stick to the diet guidelines and attend regular check-ups. Ensure your aligners fit well and replace them as instructed. Address any dental issues before starting the treatment and use any prescribed accessories properly.

By avoiding common mistakes, you enhance the effectiveness of your treatment, bringing that flawless smile within reach sooner.
