Numbers you need to know when you get Invisalign in SW14

It’s hard to be precise in a general article about Invisalign in SW14. This is because everyone’s teeth necessitate a different treatment plan. However, at Sheen Dental, we want to offer you some of the general numbers that relate to this type of treatment. It can give you a place to start from when contemplating whether this is the right treatment for you.

Not everyone can work with Invisalign. This is either because it is not clinically possible to achieve the results they want using this method or because they would prefer something like a fixed-system so that they can get braces fitted and forget about them.

How many aligners?

Each patient gets a unique set of aligners that is custom-made after we gather data about the smile you have and the smile you want at Sheen Dental in SW14. Invisalign treatment involves working your way through this series. You might have less than 10 aligners or you could have more than 40, depending on how far your teeth need to be moved.


Each aligner shifts the teeth a little bit. The average movement at each step is between 0.25 and 0.33mm. This gradual shift is gentle enough that you should not experience any serious discomfort. When you change to a new aligner, it can feel tight and like your teeth are under pressure, but this is necessary to effect the change.

Wearing your aligners

Aligners need to apply near-constant pressure in order to be effective. This means that they need to be in place for 20–22 hours of every day during treatment. If you want to take your aligner out for any reason other than to eat, drink or clean your teeth, you need to think about how long it will be out for and whether this will affect the results of your treatment.

Each aligner needs to be worn for 1-2 weeks. This depends on the method you are using. Some people can now consider faster treatment than before with aligners that change every week.
