Retainers After Braces & Invisalign®: Types, Benefits & Care Tips
You’ve invested months and sometimes years in achieving a straighter smile through braces or Invisalign® treatment. The last thing you want is for your teeth to gradually drift back to where they started. That’s exactly where retainers come in, and understanding how they work is one of the most important steps in your orthodontic journey.
At 41 South Bar, our Banbury orthodontic team fits retainers for patients every week, and we know the questions that come up time and again. In this guide, we’ll cover everything you need to know about Invisalign® – from the different types of retainers available to how long you’ll need to wear them, how to care for them properly, and what happens if you stop wearing them.
Why Are Retainers Important After Orthodontic Treatment?
When braces or Invisalign® aligners move your teeth into their new positions, the surrounding bone, ligaments, and gum tissue haven’t yet fully adapted. Your teeth are held in place during treatment, but once that external force is removed, they have a natural tendency to shift back – a process orthodontists call “relapse.”
A study published in Scientific Reports found that some degree of relapse is expected in nearly 70% of orthodontic patients, with teeth potentially shifting between 0.6 and 3.5 mm depending on the retention approach used (Source: Nature, Scientific Reports, 2023). Meanwhile, a 2025 review in Science Direct noted that only about 10% of treated patients still have clinically acceptable lower teeth alignment 10 – 20 years later if no retainer is worn at all (Source: ScienceDirect, 2025).
In simple terms, without a retainer, there’s a very high chance your teeth will move. A retainer is the insurance policy that protects your investment – whether you spent months in Invisalign® clear aligners or years in traditional braces.
What Are The Different Types Of Retainers
Retainers generally come in two types, including:
- Permanent retainers: Thin wires attached behind your teeth, invisible to others. They are usually kept in place for several years (depending on the severity of teeth misalignment), maintaining your smile’s alignment.
- Removable retainers: They are typically clear plastic that fit over your teeth. While popular for being nearly invisible, they require diligence in wearing and maintenance.
Permanent or fixed retainers are ideal if you prefer not to remove your retainer frequently for eating or brushing, ensuring your smile stays in place.
Do Retainers Straighten Teeth?
This is one of the most commonly asked questions we receive. Retainers are not designed to actively straighten teeth – that’s the job of braces or Invisalign® aligners. Instead, retainers maintain the corrected alignment by holding your teeth in their new positions while the surrounding bone and tissue fully stabilise.
How Long Do You Need To Wear A Retainer?
Here’s a general guide, though your orthodontist’s specific instructions should always take priority:
| Time After Treatment | Recommended Wear (Removable Retainers) | What’s Happening |
|---|---|---|
| Months 1 – 3 | Full-time: 20 – 22 hours/day | Bone and tissues actively stabilising around teeth |
| Months 3 – 6 | Transitioning to nighttime only (10 – 12 hours) | Most active remodelling completed; teeth more stable |
| Months 6 – 12 | Nighttime only (8 – 10 hours) | Continued stabilisation; retainer may feel loose – this is normal |
| Year 1+ | Several nights per week, potentially for life | Teeth naturally shift with age; nighttime wear maintains alignment |
For patients with more severe original misalignment, longer periods of full-time wear (up to 6 – 10 months) may be recommended before transitioning to nights only.
If you have a bonded retainer, it works for you around the clock without any action required. However, you’ll still need regular dental check-ups to ensure the wire remains intact and properly bonded.
How Should I Care For My Retainer?
Proper care for your retainer involves regular cleaning to remove food particles, bacteria, and plaque buildup.
For Removable Retainers
- Clean daily: Gently brush your retainer each time you remove it using a soft-bristled toothbrush and lukewarm water
- Rinse before reinserting: Always rinse your retainer with water before putting it back in your mouth
- Store safely: When your retainer isn’t in your mouth, it should be in its protective case – never wrapped in a tissue or napkin (this is one of the most common ways retainers are accidentally thrown away). Keep it away from pets, as dogs in particular are known for chewing retainers
- Avoid heat: Never place your retainer in hot water, a dishwasher, or a microwave. Heat can warp the plastic and ruin the fit. Even leaving it on a sunny windowsill or in a hot car can cause damage
- Don’t eat or drink with it in: Remove your retainer before eating or drinking anything other than plain water. Coloured or sugary drinks can stain clear retainers and encourage bacterial growth
- Soak occasionally: Consider using a retainer cleaning solution (such as Retainer Brite) or denture-cleaning tablets once or twice a week for a deeper clean. This helps remove plaque and odour-causing bacteria
For Fixed Retainers
- Thread your floss: Use floss threaders or specialised orthodontic floss (such as Superfloss) to clean beneath and around the bonded wire. Interdental brushes are also excellent for reaching between the teeth where the wire sits
- Brush thoroughly: Pay extra attention to the area around the wire when brushing
- Attend regular check-ups: We recommend seeing your Banbury dentist and hygienist regularly – ideally every six months to check the retainer is intact and to professionally clean the area around it. Read our guide on dental flossing and why it’s essential for more tips
- Report any issues promptly: If you feel the wire has come loose, shifted, or detached from any tooth, contact our practice as soon as possible
The Wider Health Benefits Of Retainers
Retainers do more than just keep your teeth straight. By maintaining proper alignment, they support your overall oral and general health in several important ways:
- Easier cleaning and better hygiene: Straight, properly aligned teeth are significantly easier to brush and floss effectively. This reduces plaque buildup and lowers the risk of both cavities and gum disease. For more on this, read our guide to maintaining great oral health
- Improved bite stability: After orthodontic treatment, the soft tissue and bone surrounding your teeth need time to fully adapt. Retainers help stabilise your bite during this critical period, reducing the risk of uneven wear on your teeth
- Speech and breathing support: Proper teeth alignment can support clearer speech and even improved breathing patterns, particularly for patients who have alignment issues affecting their airway
- Supporting overall health: It’s important to remember that oral health affects overall health. The benefits of wearing retainers extend beyond alignment – they contribute to long-term wellbeing by helping to prevent issues linked to poor oral health, such as gum disease and its associated risks
- Maintaining space for wisdom teeth: Retainers help ensure there is adequate space in the jaw for emerging teeth such as wisdom teeth, reducing the risk of overcrowding or further shifting
- Protection of your financial investment: Orthodontic treatment – whether Invisalign® or traditional braces represents a significant investment of both time and money. Wearing your retainer consistently is the simplest and most cost-effective way to protect that investment for life
