Braces aren’t the only way to get straighter teeth. Clear aligners are another alternative you can look into. These are plastic dental trays that work like braces—they apply pressure to straighten your teeth while worn.
However, aligners are cheaper and more convenient, and most brands offer remote progress monitoring or require fewer dental visits.
They’re also more comfortable and less visible than braces. Although their biggest advantage is that you can remove them anytime.
Several companies currently offer clear aligners in the UK. We’ll help you pick one that best suits your needs and budget.

Here are five things to consider when deciding on the best clear aligner for your needs:
You can choose from in-office and at-home clear aligners depending on your condition.
In-office clear aligners like Invisalign work on mild, moderate, and severe cases. At-home clear aligners such as NewSmile work on mild to moderate teeth misalignments.
You should talk to a registered dentist or orthodontist to determine which orthodontic treatment suits you. They can help you explore alternative options, such as clear braces or invisible braces.
Pick a clear aligner brand that makes it easy to begin treatment.
In-office treatment requires you to visit a provider in your area for an initial consultation and to see them regularly throughout the treatment.
Most at-home aligner companies offer teeth impression kits. Although some brands may give you the option to visit a specialist for an in-person scan.
Consider which treatment options are available before deciding on a brand.
In-office clear aligner systems tend to offer structured treatment plans based on your age and condition. Your provider will help you decide which is best for you.
Most clear aligner companies offer daytime and nighttime aligners, or aligner treatments based on the severity of your condition. You get to choose your treatment.
At-home clear aligners are less expensive than in-office aligners. You want to compare the costs of different brands and find one that fits your budget.
You can use qualified dental insurance to reimburse some of the treatment costs. Be aware of any price differences if you pay in full or monthly installments. Other costs to consider are:
If you’re not satisfied with the results of your clear aligner therapy, some brands may offer a lifetime smile guarantee to cover the cost of new aligners. Others may charge for refinements.
Most brands of invisible aligners offer financing. This allows you to pay for your treatment with affordable monthly installments.
Go for a brand that can give you results within an acceptable time frame.
Each brand has a different average treatment time. This will help you gauge how long you must undergo treatment before you see results.
Remember that the time it takes to get straight teeth will depend on your condition and if you follow the prescribed wear schedule for all your aligners.
