Invisalign, Angel Aligner or Braces?

Invisalign and Angel Aligner are both clear, removable aligner systems. Fixed braces are bonded to the teeth. Aligners are less noticeable and come out to eat and clean, but they only work if you wear them about 22 hours a day. Both aligner systems start from £3,490 at our Kenilworth and Stratford-upon-Avon practices.

Here is how the three options compare, and how we help you choose.

What is the difference between aligners and fixed braces?

Clear aligners are a series of thin plastic trays, each made to move your teeth a small amount. You change to the next set at set intervals. Fixed braces use brackets and a wire attached to your teeth, adjusted at regular visits. Fixed braces cannot be taken out, so they do not depend on you remembering to wear them.

How do Invisalign and Angel Aligner compare?

Both are clear aligner systems that use a 3D scan and digital planning. They differ in the plastic material, the software used to plan treatment and the features available for certain types of tooth movement. For many people either system can work well. Your dentist will recommend one based on your teeth and the movements needed, not on brand alone.

Which option suits which cases?

• Aligners often suit mild to moderate crowding, spacing and some bite problems in adults and older teenagers.
• Fixed braces may be better for some complex movements, or for people who are unlikely to wear aligners consistently.
• Any decay or gum disease needs treating first, whichever option you choose.

We will tell you honestly if aligners are not the right tool for your case.

What is it like to wear aligners?

Most people feel pressure or tightness for a day or two after changing to a new set. Speech can be slightly affected for the first few days. You take aligners out to eat and drink anything other than water, then brush before putting them back. See living with clear aligners for day-to-day tips.

What about cost?

Invisalign and Angel Aligner both start from £3,490. Retainers afterwards start from £150 each (removable) or £160 (fixed). See our full Invisalign cost guide.

Frequently asked questions

Is Angel Aligner as good as Invisalign?

Both are established clear aligner systems, and for many cases either can work well. Your dentist will recommend the system that suits the movements your teeth need.

Are aligners faster than braces?

Not necessarily. Treatment time depends on how much your teeth need to move and, with aligners, on wearing them for about 22 hours a day.

Can I have aligners at both practices?

Yes. Invisalign and Angel Aligner are available at our Kenilworth and Stratford-upon-Avon practices, from £3,490.
