Risks and Limitations of Clear Aligners

What are the risks and limitations of clear aligners?

Clear aligner treatment has limits. Not every bite or tooth movement is

appropriate for aligners, and unsupervised use carries real risks. In New

Zealand, treatment is meant to be planned and monitored by a dentist or

orthodontist registered with the Dental Council of New Zealand.

What can this page establish, and what can't it?

This page lists general risks and limitations. It cannot assess your

specific case, and it does not give a wear schedule or instructions to

continue or stop any device.

Warning signs to take seriously

Seek a registered practitioner promptly if you notice:

• pain that does not settle;
• teeth that are not fitting into the aligners as planned;
• gum problems or unusual movement;
• any damage to teeth.

Why supervision matters

Moving teeth affects roots, gums, and bite. A practitioner reviews

progress at intervals to confirm movement is happening as planned and to

change the plan when it is not. Treatment without this review removes the

safety net the design of supervised care depends on.
