Retainers for Kids and Teens: Wear Time, Replacements, and Parent Checklists
Finishing braces or Invisalign is a big milestone, but the last day of active treatment is the first day of retention. Retainers help teeth stay where they belong while the bone and ligaments around them stabilize. With the right wear habits and simple care, you can protect your teen’s new smile for years to come. At Kahan Orthodontics in Tarzana, we teach families how to manage retainers with clear steps and ongoing support.
Why Retainers Matter
Once braces or aligners come off, teeth have a natural tendency to drift toward their original positions. Retainers act as a placeholder while the supporting tissues adapt to the new alignment. Consistent wear reduces the chance of relapse and helps keep the bite stable.

How Long To Wear a Retainer
Every smile is unique, so your plan may differ. These general stages are common.
- Initial phase. For the first several months after treatment, most teens wear retainers close to full time. Remove only for meals and brushing.
- Maintenance phase. Once the bite is stable, wear usually shifts to nights. Many patients do best with a “nighttime for a lifetime” routine.
- Consistency counts. Skipping wear for even a few nights can make the retainer feel tight when it goes back in. That tightness is a sign that some shifting has started.
Daily Care Made Simple
Clean, well-fitting retainers are more comfortable and last longer.
- The case rule. If it is not in your mouth, it should be in the case. Most lost retainers are wrapped in napkins and thrown away by mistake.
- Daily cleaning. Use a soft toothbrush and cool water. Avoid hot water, which can warp plastic retainers.
- Morning check. Before school or sports, make sure the retainer is either in the mouth or in the case and in the bag.
Signs It Is Time To Call Us
Even with great care, retainers can wear out or go missing. Contact our Tarzana office at 818-578-8782 if you notice:
- A tight or painful fit. This can mean teeth have started to shift or the retainer has warped.
- Cracks or thinning. A worn retainer may break and should be replaced before it fails.
- Lost or broken retainer. Do not wait. The sooner we act, the easier it is to maintain your result.
We can review insurance, FSA or HSA options, and replacement fees before ordering a new appliance.

Types of Retainers
Your orthodontist will recommend the design that fits your needs and lifestyle.
- Clear removable retainers. Often called Essix retainers, these look similar to clear aligners and are discreet and easy to wear.
- Hawley wire retainers. Durable and adjustable, with a thin wire across the front teeth.
- Fixed retainers. A small bonded wire behind the front teeth that holds spacing and alignment. Many patients use a fixed retainer plus a nighttime removable retainer.
Tips for Busy Families
- Create a routine. Keep the case in the same pocket or bag so it is always easy to find.
- Travel kit. Pack a case, travel brush, and floss picks for sports and trips.
- Stay connected. If you are away, call or text the office and we can advise you on next steps. Virtual check-ins are available when appropriate.
The Bottom Line
Retention is how you protect all the effort that went into straightening your teen’s teeth. A steady nighttime routine, simple cleaning habits, and timely replacements when needed can keep the smile stable and healthy.
