As much as any other branch of dentistry, orthodontics has seen a lot of changes over the last several years.  Not only in the methods of treatment, but also in the age of the patient.  It is estimated that at least 25 percent of all orthodontic patients are adults – including senior citizens.  Orthodontics – the art and science of shifting teeth into their optimal position is in the throes of a 21st century revolution, driven perhaps by patient demand, but inspired by new materials and new technologies that allow for lighter, smaller, less conspicuous appliances. 

I have a lot of adult patients who are being treated with orthodontics.  Not only are they being treated for cosmetic reasons, but as much as anything for an improvement in health and function.  Malaligned teeth are harder to clean and therefore more prone to decay and gum disease.  As well, biting forces placed on straight teeth are more evenly distributed than those applied to crooked teeth. 

The good news is that orthodontic treatment is no longer a mouth full of banded teeth and heavy wires.  Smaller brackets and resilient titanium brace “wires” with advanced properties sustain gentler, lighter forces in moving teeth.  Patients who are missing anchor teeth for braces can now have implants placed to secure the wires and move teeth.

But one of the most interesting advances is the use of computer imaging to create a series of clear, removable aligners (trays) that are prefabricated for the patient to move their teeth in small increments without the use of wires.  This is the technology behind Invisalign.  “Periodic tightenings” which are basic to the straightening process is made by changing to a new aligner every 2 to 3 weeks.  The aligners are based on software that “predicts” the final position the teeth will take as determined by 3-D x-ray scanned molds of the teeth.  Using these molds, the computer breaks down the straightening into stages and a series of aligners are made to slowly move the teeth.  The trays are clear, but must be worn 22 to 24 hours a day.  One advantage is that Invisalign-ers are easily removed for eating, brushing and flossing.  Since no metal is present, they are also often more comfortable to wear.  

Now for the bad news.  Not everyone is a candidate for Invisalign.  More severe malalignments are often better treated with conventional orthodontics and Invisalign treatment time can be longer in many cases.  In many instances, the fees can be higher than standard treatment because of the number of trays that must be made.

It’s never too late to have your teeth straightened.  With the advances in modern dentistry, a healthy smile is attainable for a lifetime.  If you are considering straightening your smile, check with your dentist or orthodontist to see what would be involved and what treatment would be best for you.
