Finished with your orthodontic treatment? Congratulations! But now comes an equally important decision: choosing between a permanent retainer or a removable one. This choice can significantly impact your dental health and the longevity of your beautiful new smile. We’ll help you understand the differences, benefits, and considerations of each option so you can maintain those perfectly aligned teeth for years to come.
What Are Retainers and Why Do You Need Them?
Retainers are orthodontic devices designed to maintain the position of your teeth after braces or clear aligners have done their job. They’re not just an optional add-on – they’re essential for preventing orthodontic relapse, which is the natural tendency of teeth to shift back to their original positions.
After orthodontic treatment, the bone around your teeth is temporarily weakened – we’ve observed it may be almost 25% thinner. This makes your newly positioned teeth unstable and prone to movement. Without proper retention, all the time, money, and discomfort you invested in straightening your teeth could be wasted as they gradually shift back.
In our practice, we’ve found that nearly 70% of patients who don’t wear their retainers consistently experience some degree of relapse within the first year after treatment. Retainers give your bone tissue time to rebuild and stabilize around the new tooth positions, helping to maintain your straight teeth long-term.
Understanding Permanent Retainers
How Do Permanent Retainers Work?
Permanent retainers (also called fixed, bonded, or lingual retainers) consist of a thin, custom-fitted metal wire that’s bonded to the back (lingual) surface of your teeth. Typically made of stainless steel or a metal alloy, these retainers are most commonly attached to the 4-6 lower front teeth, though they can sometimes be placed on upper teeth as well.
The bonded wire retainer is completely invisible from the front, as it sits behind your teeth. Once placed by your orthodontist, permanent retainers remain in position 24/7 without any action needed on your part. With proper care, a permanent lingual retainer can last 10-20 years before requiring replacement.
Advantages of Permanent Retainers
Permanent retainers offer several significant benefits:
Compliance-free results: You don’t need to remember to put them in or take them out – they’re always working to prevent teeth shifting.
Completely invisible: Since they’re bonded to the back of your teeth, no one will know you’re wearing a retainer.
Continuous protection: They provide 24/7 stability for your most shift-prone teeth (typically the lower front teeth).
Durability: With proper care, permanent retainers can last for many years without replacement.
Ideal for forgetful patients: There’s no risk of losing them or forgetting to wear them.
Disadvantages of Permanent Retainers
Despite their benefits, permanent retainers do come with some challenges:
Cleaning difficulties: You’ll need special tools like floss threaders or interdental brushes to clean properly around and under the wire.
Plaque buildup risk: The wire creates additional surfaces where plaque can accumulate, potentially leading to tartar, cavities, or gum disease if not cleaned properly.
Potential breakage: Hard or sticky foods can bend or break the wire, requiring an emergency visit to your orthodontist.
Limited protection: They typically only stabilize the front teeth, not the entire arch.
Tongue irritation: Some patients experience initial discomfort as their tongue adjusts to the wire presence.
Understanding Removable Retainers
How Do Removable Retainers Work?
Removable retainers come in several varieties, with the most common being:
Hawley retainers: These traditional retainers feature an acrylic base that fits against your palate or behind your lower teeth, with a visible wire that wraps around the front of your teeth. They’re durable and adjustable.
Essix retainers (clear retainers): Made of transparent plastic, these fit over your entire dental arch like a thin mouthguard. They’re nearly invisible when worn.
We typically recommend wearing removable retainers full-time (20-22 hours daily) for the first 3-6 months after treatment, then transitioning to nighttime wear only. This schedule may vary based on your individual needs and specific circumstances.
Advantages of Removable Retainers
Removable retainers offer several distinct benefits:
Easy cleaning: You can remove them to brush and floss your teeth normally, without any special tools.
No dietary restrictions: You can take them out when eating, so there’s no need to avoid certain foods.
Versatility: Clear plastic retainers can double as whitening trays or nightguards for teeth grinding.
Full arch coverage: They stabilize all teeth, not just the front ones.
Temporary removal option: You can briefly remove them for special occasions if needed.
Disadvantages of Removable Retainers
The flexibility of removable retainers comes with some drawbacks:
Compliance required: They only work when you actually wear them – so self-discipline is essential.
Loss risk: They’re frequently removed and transported, increasing the chance of being misplaced or accidentally thrown away.
Visibility concerns: Hawley retainers have visible metal components, while clear retainers may yellow over time.
Replacement needs: They wear out faster than permanent retainers, typically requiring replacement every 1-5 years depending on the type and care.
Speech impact: New removable retainers may temporarily affect your speech until you adjust to wearing them.
Maintaining Your Retainer
How to Clean a Permanent Retainer
Proper maintenance of your permanent retainer is crucial for both your retainer’s longevity and your oral health:
Daily cleaning routine:
- Use a soft-bristled toothbrush to carefully brush around the wire and bonding points
- Angle the brush to clean under and around the wire thoroughly
- Consider using a water flosser for easier cleaning beneath the wire
Specialized flossing:
- Use floss threaders or SuperFloss to thread regular floss under the wire
- Gently clean between each tooth and along the gumline
- Interdental brushes can also help reach difficult areas around the wire
Regular dental checkups:
- We’ll check your permanent retainer at least twice a year during your regular visits
- Professional cleaning helps remove calcified plaque buildup that home care might miss
- We can check for any wire failure or loose bonding points before they become problems
How to Care for Removable Retainers
Proper maintenance extends the life of your removable retainer and keeps it hygienic:
Daily cleaning:
- Brush your retainer gently with a soft toothbrush whenever you remove it
- Use lukewarm (never hot) water and mild, non-abrasive soap or specialized retainer cleaner
- Avoid regular toothpaste, which can scratch and cloud clear retainers
Regular soaking:
- Soak in retainer cleaning solutions like Retainer Brite or DentaSoak once daily
- For Hawley retainers, occasional soaking in diluted vinegar solution can help remove calcium buildup
- For clear retainers, avoid colored mouthwashes that might stain the plastic
Proper storage:
- Always store your retainer in its ventilated case when not in use
- Keep away from heat sources and direct sunlight, which can warp plastic retainers
- Keep out of reach of pets (dogs love to chew on retainers!)
Replacement timeline:
- Clear plastic retainers typically last 1-3 years before needing replacement
- Hawley retainers are more durable, often lasting 5-8 years with proper care
- If your retainer develops cracks, sharp edges, or no longer fits properly, it’s time for a replacement
