Clear aligners and gum health: why it is checked first
Moving teeth relies on healthy gums and bone. That is why gum health is assessed before aligner treatment and monitored throughout it.

Why healthy gums matter
Teeth move through the bone that supports them. Active gum disease weakens that support, so moving teeth before it is controlled can increase the risk of further damage.
The assessment
Your dentist checks gum pockets, bleeding and bone levels, often with X-rays. Many people have mild inflammation that settles with hygiene treatment and better home care.
Treating gum disease first
Where gum disease is active, it is usually treated and stabilised before aligners begin. Some people with a history of gum disease can still have alignment once it is controlled.
Monitoring and referral
Regular hygiene visits continue during treatment. In more complex cases a referral to a specialist periodontist may be recommended.
Questions patients ask
- Can gum disease delay alignment? Yes, if it needs treating first.
- Who checks gum health? Your dentist and hygienist, at assessment and at reviews.
- Could I need a referral? Sometimes, for advanced or complex gum disease.
