How to Clean Invisalign Aligners (and How They Actually Move Your Teeth)

We recently had a patient ask us two really good questions about Invisalign:

“Can I clean my aligners with normal toothpaste?”

And:

“If the aligners stay in place, how do they move my teeth?”

If you've wondered the same thing, you're definitely not alone.

Clear aligners may look simple, but there is quite a lot going on behind the scenes. And looking after them correctly can help keep them clear, fresh and comfortable throughout your treatment.

So, let's answer both questions.

Can you brush Invisalign aligners with toothpaste?

It's usually best not to clean your Invisalign aligners with normal toothpaste.

This doesn't mean you should stop using toothpaste on your teeth. You should continue brushing your teeth with fluoride toothpaste as recommended by your dental team.

The difference is the aligners themselves.

Some toothpastes contain abrasive ingredients designed to help clean the surface of your teeth. These can create tiny scratches on clear aligners.

Over time, this may make your aligners look dull or cloudy rather than clear.

So: toothpaste for your teeth, but not necessarily for your aligners.

How should you clean Invisalign aligners?

When you take your aligners out, rinse them with cool or lukewarm water.

You can gently clean them using a soft toothbrush kept specifically for your aligners, along with a suitable clear aligner cleaner.

Avoid very hot water. Heat can affect the plastic and potentially change the shape of your aligners.

It's also worth cleaning your aligners regularly rather than waiting until they look dirty or start to smell.

And don't forget the case!

Keeping your Invisalign case clean is another simple way to help keep your aligners fresh.

Should I brush my teeth before putting Invisalign back in?

Good oral hygiene becomes particularly important when you're wearing clear aligners.

Food and plaque left on your teeth can become trapped underneath the aligner.

Ideally, clean your teeth before putting your aligners back in after eating. Your Invisalign provider can give you personalised advice on brushing, flossing and looking after your teeth during treatment.

If you're out for the day, it can be useful to carry a small dental kit with you.

A toothbrush, toothpaste, floss or interdental brushes and your Invisalign case don't take up much room.

Why have my Invisalign aligners gone cloudy?

There are several reasons clear aligners can start to look less clear.

Scratching them with abrasive products can affect their appearance. Drinks can also stain them, and plaque or deposits can build up if they aren't cleaned properly.

One of the attractions of Invisalign is how discreet the aligners can be, so looking after them matters.

If your aligners repeatedly become cloudy, stained or develop an odour, speak to your Invisalign provider. They can check your cleaning routine and recommend the best way to care for them.

Can I drink coffee while wearing Invisalign?

It's generally best to remove your aligners for drinks other than plain water, unless your dental team has advised you differently.

Coffee, tea and other coloured drinks may stain clear aligners.

Hot drinks can also expose the aligner material to heat.

And sugary or acidic drinks can become trapped between your teeth and aligners, which isn't ideal for your dental health.

So if you're having your morning coffee, take your aligners out, store them safely in their case, and follow the cleaning advice you've been given before putting them back in.

But how does Invisalign actually move teeth?

This is the clever part.

Your Invisalign aligners are not simply plastic copies of your teeth.

Your treatment is planned so that a series of aligners gradually guides your teeth towards their intended positions.

Each aligner is slightly different.

When you put an aligner in, it applies controlled pressure to certain teeth. Your teeth respond to those forces and gradually move.

Once you've worn that aligner for the prescribed amount of time, you progress to the next stage according to your treatment plan.

Think of it as a sequence rather than one aligner doing all the work.

Why doesn't the Invisalign aligner move instead of my teeth?

This was the part our patient was particularly curious about.

The aligner is designed to fit closely around your teeth. Depending on your treatment, you may also have small attachments placed on certain teeth.

These are small, tooth-coloured shapes that help the aligner apply force in a more controlled way.

Your aligner may therefore feel particularly snug when you first change to a new one.

Over time, your teeth respond to the planned forces being applied.

This is also why Invisalign treatment needs to be planned and monitored rather than simply giving you a set of trays and hoping your teeth end up in the right place.

What happens if I don't wear my Invisalign enough?

Clear aligners only work when you're wearing them.

Your dentist or Invisalign provider will tell you how long you should wear yours each day. Invisalign treatment commonly requires aligners to be worn for most of the day and night, removing them mainly for eating, drinking and cleaning.

If they aren't worn as instructed, your teeth may not move as planned.

You might then notice that an aligner doesn't fit as well as expected or that you're not ready to move on to the next stage.

If you've forgotten to wear your aligners or they suddenly don't fit properly, don't guess what to do next. Contact your dental team for advice.

Is Invisalign difficult to look after?

For most people, looking after Invisalign quickly becomes part of their daily routine.

The basics are quite simple:

Keep your teeth clean. Keep your aligners clean. Remove them when advised. Store them safely. And wear them for the recommended amount of time.

The important thing is knowing what to do from the start.

That's why we encourage our patients to ask questions – even the ones that might seem obvious.

Often, they're the best questions.

Thinking about Invisalign in Lytham St Annes?

If you're considering Invisalign but aren't sure how it would fit into your everyday life, ask us.

You may want to know whether Invisalign could work for your teeth, how long treatment could take, what it costs, whether you'll need attachments, or simply how you'll manage coffee during the working day.

Your treatment should start with understanding your teeth and what you'd like to change.

At The Lytham Dental Clinic, we can assess your smile, discuss whether Invisalign may be suitable for you and explain what treatment would involve before you decide whether you'd like to go ahead.

Because knowing how your treatment works can make looking after your new smile much easier.
