How Long Do I Need a Retainer After Invisalign?

A patient holing a retainer to use after Invisalign in Raleigh

Invisalign really is a convenient orthodontic treatment. Instead of using metal brackets and wires, it relies on clear plastic trays that straighten teeth in just a year! Still, the process has its share of aftercare needs. In particular, it has you use a retainer to preserve your straightened smile. You may be wondering, then, what the timeline is for this new appliance. To help you learn the answer, here’s a summary of how long and why to wear a retainer after finishing Invisalign in Raleigh.

How Long Should I Wear the Retainer?

Technically, you should use a retainer post-Invisalign for the rest of your life. That doesn’t mean wearing it 24/7, mind you, but you’ll need to wear it at regular intervals from now on.

Right after finishing treatment, for example, you’d wear a retainer day and night. This stage would then go on for about three to six months.

After those first months, you’ll be able to wear it just at night. Over time, it may be possible to only use it every two to four nights, depending on if it feels tight.

Why Do I Need to Do So?

As referenced above, you need to wear a retainer to preserve your Invisalign results.

You see, teeth won’t just stay straight once you finish with the trays. Left alone, they’ll naturally (and quickly) start to shift back to their original and crooked positions. This reversion is especially likely in the first few months after the straightening process.

It’s crucial, then, to wear the retainer. Doing so will fix your teeth in their final, perfect position and stop unwanted movements. On the other hand, going without the retainer will cause your treatment to come undone.

Retainer Care Tips

To ensure your retainer keeps your teeth “in shape,” you’ll need to care for it. That said, how you do so will depend on whether it’s fixed or removable.

If it’s a fixed retainer, clean it alongside your teeth. You’ll need to brush the wire gently with a toothbrush. Also, use interdental brushes between teeth to remove plaque.

Per their name, removable retainers should be removed and cleaned twice daily. For the latter task, use plain warm water and a toothbrush. Ensure not to include toothpaste, as it would take the shine off the Invisalign retainer.

As you can see, a retainer is a lifelong commitment after you’ve finished Invisalign in Raleigh. Remember to wear it daily so your straight smile lasts for many years.

I've been coming to this practice for years now since moving to the Raleigh area. The office is always clean and organized and the staff have always been friendly and communicative. Also, the TV's mounted to the ceiling are a nice touch! I've been seeing Dr. Laster for several years before our insurance changed causing me to change to Dr. Rensch. Both are so easy to talk to and always made me feel at ease.

From beginning to end 5/5! I thought I was experiencing a dental 911. I submitted an inquiry at 11:30pm and by 8am the next morning, Deidra (front office staff) was already leaving me a message. She was so sweet and patient at 8am lol. After our initial conversation, I informed all follow up dentists “I found my dentist office” but thank you so much! Today I was welcomed with the same energy from Diedre to Britany then finally Dr.Wrench. The music playing throughout the office was fantastic; ie music selection and volume. The TV’s on the ceiling and wall made my procedure so painless and enjoyable! I watched an entire Christmas movie lol! Dr. Wrench (apologies for spelling) made my teeth absolutely perfect! I left telling my friends and family I have a million dollar smile! 😊 I can tell he wanted them perfect and he did! Thank you all so much for being amazing! Sincerely, Your next patient.

Dr. Laster and Dr. Rensch go above and beyond for their patients. I have seen both for various treatments and I always feel comfortable and heard. They take time to listen and to talk with you. They explain your options and work with you to develop the best plan for your care. They are always upbeat and positive and you can tell they truly love what they do. The front desk staff is exceptional as well. Deidre is so caring and very sweet. She’s efficient, understanding and conscientious of your time. I highly recommend.

Connections Dentistry was great! The staff is so friendly and truly cares about their patients. My appointment was quick, and honestly the best dental experience I’ve had. They are great about offering helpful solutions without making you feel like you are being reprimanded… which was the reason I was putting off the dentist. 100% recommend!
