Here are a list of common questions asked by dentists and patients using Smilelign Clear Braces & Aligners

How Long Should I Wear My Invisible Braces For Each Day?

The longer you wear your Smilelign aligners each day, the more effective and quicker your treatment will be. We suggest around 22-23 hours per day, only removing them to eat and clean them.

Can I Drink With My Aligners In?


Drinking water whilst wearing your braces is fine. Under no circumstances should you drink carbonated, sugary or acidic drinks such as fresh juice, fizzy drinks and energy drinks as this can lead to corrosion of your teeth. If you need to drink these types of drinks you must remove your clear braces and make sure you clean your teeth and the brace before inserting them back on your teeth.

Can I Drink Tea & Coffee?

Again it is recommended that your Smilelign braces are removed when drinking hot drinks like tea and coffee, not only can it lead to staining of your teeth but the heat can damage the thin plastic of the braces and prevent them working or deform them.

Can I Eat With My Aligners In?

No! Even really soft foods can damage the plastic when chewing. It is recommended that all drinking and eating is kept to mealtimes when you can remove your braces. If you eat or drink with the aligners in food debris and liquids can become trapped between your teeth and the clear plastic, not only will it look unsightly but it can lead to decay or acid in the fluid can erode the enamel of your teeth. We only recommend drinking still water whilst wearing your clear aligners.


When Should I Change My Aligner For The Next Stage?

We find that Smilelign aligners have achieved their movements within 3-4 weeks. However, do not move onto the next aligner until the one you are wearing is completely finished and never move on to the next aligner in less than 3 weeks.You should only move onto the next aligner when:

  • The aligner can be removed and fitted in easily and...
  • There is no pressure felt on any of your teeth and...
  • It should also fit perfectly with no obvious gaps or spaces between the aligner and teeth.



If the aligner is still extremely tight move back to the previous aligner for another week or two then try the next aligner again. If after a further period it is still tight then we recommend you contact your dentist. If you move on too quickly this will result in treatment taking longer or even worse the teeth can stop moving. 

Does Smilelign offer a guarantee?

Smilelign is an effective way of straightening teeth and works similar to traditional methods of orthodontics but largely depends upon a patient’s biology and compliance with treatment. As such, Smilelign as with any orthodontic treatment, cannot guarantee that your teeth will move exactly as predicted. The prescribing orthodontist or dentist is responsible to use their experience and skill to treatment plan and monitor the appropriate treatment as it progresses. If necessary, additional treatment with Smilelign or other forms may be needed. It is essential that appropriate consent is discussed and obtained from the patient prior to starting treatment.
