Invisalign clear braces work in the same manner as traditional braces. Invisible braces results will not differ from that of metal braces, nor take less or more time in the process. You teeth cannot tell the difference between metal and plastic, they will respond to gentle pressure in the same way.
The cost of invisalign and metal braces in London don't differ much. However, unlike traditional braces which are applied to the teeth in the dental chair, invisalign is constructed in a lab so lab fees may account for a higher cost.
The benefit of invisalign in London, as you may have heard in many invisalign reviews, is the the aligners are clear. This way you don't have to alter the look of your smile while you are improving it. These clear plastic aligners are virtually unnoticable so no one will know you are undergoing treatment except you.
Another added benefit in the invisalign vs braces debate is that the aligners are removable. You can eat normally, brush and floss normally without interruption to your daily routine. Also the clear aligners are smooth and is less likely to irritate your teeth and gums. An added bonus? They are virtually invisible!
