For information on Sure Smile aligner therapy please look at

  • Sure Smile uses a series of clear removable aligners to straighten your teeth without metal wires or brackets.
  • The aligners are made through a combination of Drs. McKenna or Tjeerdsma‘s expertise and 3-D digital imaging technology.
  • You wear each set of aligners for 2 weeks, removing them only to eat, drink, brush, and floss.
  • As you replace each aligner with the next in the series, your teeth will move – little by little, week by week – until they have straightened to the final position Drs. McKenna or Tjeerdsma has prescribed.
  • You’ll visit Drs. McKenna or Tjeerdsma about once every 4 weeks to ensure that your treatment is progressing as planned.
  • Total treatment time averages 9 – 15 months and the average number of aligners worn during treatment is between 18 and 30, but both will vary from case to case.
