Straighten Your Smile, Your Way
Retainers help keep your teeth from shifting after braces or Invisalign. Once active orthodontic treatment ends, your teeth still need support while the surrounding bone, gums, and bite settle into their new positions. At Lasley Orthodontics, we provide retainer guidance in Renton, WA to help patients protect their results and keep their smiles stable long term.
Whether you recently finished treatment, lost your retainer, broke your retainer, or noticed your teeth starting to move, Dr. Andrew Lasley, DMD can help you understand the next step.

What Are Retainers?
Retainers are custom orthodontic appliances made to hold your teeth in place after active treatment. Braces and Invisalign move the teeth into better positions. Retainers help keep them there.
This matters because teeth naturally tend to shift over time. Even after excellent orthodontic treatment, your teeth can move if it is not supported properly. That is why retainer wear is not an optional final detail. It is part of the full orthodontic process.
Lasley Orthodontics provides retainer instructions to help patients understand how to wear, clean, store, and care for their retainers.
Why Retainers Matter After Braces or Invisalign
Finishing treatment is exciting, but your teeth are not permanently locked into place the day your braces come off or your last Invisalign tray is complete. The tissues around the teeth need time to stabilize.
Without retainers, teeth can gradually shift back toward their old positions. This is called orthodontic relapse. It can happen slowly at first, but small changes can become more noticeable over time.
Retainers help protect the work you have already done. They can also reduce the chance of needing additional orthodontic treatment later.
If you completed Invisalign and braces, your retainer plan is what helps preserve the result.
Who Needs a Retainer?
Most patients need retainers after orthodontic treatment. This includes children, teens, and adults who completed braces, Invisalign, Invisalign Teen, or other orthodontic care.
You may need a retainer visit if:
- your retainer feels tight, loose, cracked, or warped
- you lost your retainer
- your teeth feel like they are shifting
- your old retainer no longer fits
- you stopped wearing your retainer for a while
- your retainer has odors, buildup, or visible wear
- you finished treatment and need retention guidance
Patients of different ages may need different retention plans. Lasley Orthodontics provides orthodontics for all ages, which means retention is planned around the patient’s smile, bite, age, and treatment history.
Types of Retainers
Different patients may need different types of retainers. The right choice depends on your teeth, bite, treatment history, and how much support your smile needs.
| Type of Retainer | How It Works | Why It May Be Used |
| Clear retainer | Fits over the teeth like a thin clear tray | Discreet, removable, often used after Invisalign or braces |
| Hawley retainer | Uses acrylic and a wire across the teeth | Durable, removable, and adjustable in some cases |
| Fixed retainer | A thin wire bonded behind the teeth | Helps support teeth that are more likely to shift |
Some patients need removable retainers. Others may benefit from a fixed retainer in certain areas, especially where shifting is more likely.
Signs You May Need a New Retainer
A retainer only works if it fits properly. If it is damaged, warped, or no longer seating well, it may not hold your teeth the way it should.
You may need a new retainer if:
- it feels painfully tight
- it feels loose or falls out easily
- it has cracks or sharp edges
- it looks warped or distorted
- your teeth have shifted
- it no longer fits over your teeth
- you lost it or accidentally threw it away
Do not force an old retainer into place if it does not fit. A tight retainer may mean your teeth have moved, and forcing it could cause discomfort or unwanted pressure. Schedule a visit instead so your smile can be checked properly.
What to Expect at a Retainer Visit
A retainer visit is usually straightforward, but the fit matters. A replacement retainer should be made from an accurate record of your current tooth position.
Your visit may include:
A Smile and Bite Check
Dr. Lasley checks whether your teeth are stable, whether shifting has started, and whether your old retainer still fits correctly.
A Review of Your Retainer
If you already have a retainer, bring it with you. The team can check for cracks, warping, wear, and fit issues.
A Scan or Impression
A new retainer may require a digital scan or impression so it can be made to fit your teeth accurately.
Wear and Care Instructions
You will receive instructions on when to wear your retainer, how to clean it, and how to store it safely.
Regular office visits help keep your orthodontic care on track, especially if you have concerns about shifting or appliance fit.

Frequently Asked Questions
Most patients need long-term retainer wear to keep their teeth from shifting. Dr. Lasley will explain how often to wear yours based on your treatment history and smile stability.
Call the office as soon as possible. Teeth can begin shifting when they are not supported, so it is best to replace a lost retainer quickly.
Do not force it. A tight retainer may mean your teeth have shifted. Schedule a visit so your smile and retainer fit can be checked.
Clean your retainer daily with a toothbrush and follow the care instructions from your orthodontist. Avoid hot water because heat can warp the appliance.
Retainers are mainly designed to hold teeth in place, not actively move them. If your teeth have shifted, Dr. Lasley can explain whether a new retainer or additional treatment may be needed.
