Compared to traditional braces, orthodontic clear aligners seem miraculous in many ways, almost too good to be true. You may be wondering if they really work. The answer is yes — but they are not for everyone.
What are orthodontic aligners and how do they work?
Clear orthodontic aligners are an alternative to traditional braces that are used to move your teeth and transform your smile without much interference to your daily life. They are removable trays made of a clear plastic material that is essentially invisible.
When using aligners, a sequence of slightly different trays is custom-made to fit over your teeth. You must wear each one 20 hours a day for two weeks before changing to the next in the series. The aligners are computer generated, designed by state-of-the-art techniques based on models and images of your own teeth. They work because slight changes in the sequential aligners gradually shift your teeth. If they are worn consistently, the process takes from six months to two or three years.
Advantages over traditional braces are:
- The aligners can be removed for eating, drinking, brushing, flossing and social occasions.
- They have no rough edges or wires, making them more comfortable.
- Changes become visible quickly as your teeth move into their new, better positions.
Clear aligners are a good solution for correcting mild to moderately crowded or incorrectly spaced teeth. They are most effective if your back teeth already fit together properly. Clear aligners are usually effective in correcting simpler or tipping movements of teeth in two dimensions. For more complex movements, traditional braces may be required. Clear aligners are usually recommended for adults whose teeth and jaws are fully developed, and not for children.
When do you need traditional fixed braces?
Traditional braces are fixed brackets attached to the teeth through which narrow, flexible wires are threaded. They may be necessary if your teeth do not meet properly, creating too much overbite or underbite. Closing spaces where teeth are missing, rotating teeth, or other complicated situations probably make you a better candidate for traditional braces.
Each particular situation is unique. To find out if clear aligners are right for you, make an appointment with us for an assessment and diagnosis of your own situation. For more information see the Dear Doctor magazine article “Clear Orthodontic Aligners.”
It used to be that the only option for straightening a teenager's teeth involved lots of shiny hardware. Besides the esthetic downside, traditional orthodontic devices (braces) can interfere with the enjoyment of certain favorite foods, irritate the inside of the mouth, trap food particles (potentially another esthetic embarrassment and sustenance for cavity-causing bacteria), and complicate dental hygiene routines.
These aren't causes for concern with clear orthodontic aligners, however, which consist of a series of transparent plastic, removable trays that fit over the teeth and gradually move them into better positioning. About every two weeks, the teen proceeds to the next aligner in the progression (or set of aligners if treatment involves both the upper and lower teeth) until the improved alignment goal is reached. The trays are meant to be worn 22 hours a day, but they can be removed for eating, brushing and flossing, and, on a limited basis, special occasions.
Thanks to relatively recent developments in the design of clear aligner systems, teens who previously were not considered good candidates for this modality may now have this option available to them. This includes:
- Teens whose second molars (the last to come in except for wisdom teeth) haven't fully emerged. Aligners now come with “eruption tabs” that serve as place-holders for teeth that are still growing into position.
- Teens with severely rotated teeth requiring complicated movement. Tooth-colored attachments called “buttons” can be temporarily bonded onto teeth to provide additional leverage, and elastics (rubber bands) can also be used to promote movement.
Compliance is always a concern with any orthodontic treatment — whether it be gum chewing with traditional braces or wearing clear aligners for the requisite period of time each day. Aligners now come with built-in colored “compliance indicators” that fade with use over time. This makes it possible for orthodontists, dentists, parents and teens alike to monitor both compliance and treatment progress.
