After braces come off, you wear a retainer. This is the single most important piece of your orthodontic treatment because your teeth will naturally try to drift back toward their original positions, sometimes within hours of having braces removed. There are three main types of retainers, each with different trade-offs for comfort, visibility, and maintenance.
The Three Types of Retainers
Clear Plastic Retainers
These are the most popular option today. Made from thin, transparent plastic or polyurethane, they’re custom-molded to fit snugly over your newly straightened teeth. Common brands include Essix, Vivera, and Zendura. They’re nearly invisible when worn, which is a big reason people prefer them. The downside is durability: the plastic stretches and cracks over time, so they typically need replacing about once a year.
Hawley Retainers
The classic retainer. A Hawley has an acrylic plate that sits against the roof of your mouth (or behind your lower teeth) with a thin metal wire that wraps around the front of your teeth. They’re more noticeable than clear retainers, but they’re sturdy and can be adjusted if your bite needs minor tweaking. Like clear retainers, they should be replaced roughly every year as the plastic component wears down.
Permanent (Bonded) Retainers
A permanent retainer is a thin metal wire bonded to the back side of your front teeth, most commonly on the bottom. You can’t see it from the outside, and you can’t remove it yourself. It stays in place 24/7, which makes it the most effective option for preventing relapse since it doesn’t rely on you remembering to wear anything. These typically last about two years before needing replacement, though some last much longer with careful maintenance.
How Long You Need to Wear a Retainer
Right after braces come off, expect to wear your removable retainer full-time: around 20 to 22 hours per day, removing it only to eat and brush your teeth. This intensive phase usually lasts three to six months, depending on how your teeth respond.
After the first year, many orthodontists allow you to scale back to a few nights per week. But most still recommend wearing your retainer every night for life. That sounds like a big commitment, but it becomes routine quickly, similar to brushing your teeth before bed. Skipping retainer wear is the single most common reason people lose the results they spent years in braces to achieve.
What Happens if You Stop Wearing It
Teeth can start shifting within hours of going without a retainer, especially in the first few months after braces are removed. Even a few days without retention can allow noticeable movement, particularly in younger patients or anyone who recently finished treatment. Over the long term, a 12-year follow-up study published in the European Journal of Orthodontics found that teeth continued to shift in all groups studied, whether or not they wore retainers, though the changes were a mix of true relapse and natural age-related movement.
The bottom line: retainers don’t just preserve your braces results. They also counteract the normal, lifelong tendency of teeth to crowd and shift as you age.
What the First Few Days Feel Like
A new retainer feels strange. Your tongue isn’t used to sharing space with plastic or wire, and your brain needs time to adapt. Most people notice a slight lisp, particularly with “s,” “sh,” and “th” sounds. Extra saliva production is common too, which can make speech feel awkward. Some mild soreness or pressure is normal, especially if your teeth are being held firmly in their corrected position.
The adjustment period is short. Most people speak normally again within a few days. Some adjust in as little as 24 hours, while others need up to a week. If a lisp or discomfort lasts longer than a week, or if the retainer feels too tight, too loose, or rubs painfully against your gums, have your orthodontist check the fit.
Choosing Between Removable and Permanent
Your orthodontist will recommend a type based on your specific bite and how your teeth responded to treatment, but you often have some say in the decision. Here’s what matters in practice:
- Visibility: Clear plastic retainers are nearly invisible. Permanent retainers are hidden behind the teeth. Hawley retainers have a visible wire across the front.
- Compliance: If you’re likely to forget or lose a removable retainer, a permanent one eliminates that risk entirely. People with memory or movement difficulties often do better with a bonded wire.
- Hygiene: Removable retainers are easier on your dental hygiene since you take them out to brush and floss normally. Permanent retainers make flossing harder and can trap food particles, increasing your risk of cavities or gum disease if you’re not diligent.
- Durability: Permanent retainers last longer overall, though they can break, particularly on upper teeth. Clear plastic retainers wear out fastest.
Many people end up with a combination: a permanent retainer bonded behind the lower front teeth (where crowding recurs most) plus a removable retainer for the upper teeth.
Cleaning and Daily Care
For removable retainers, the routine is simple. Clean yours daily with tepid soapy water (fragrance-free liquid soap works well) and a soft toothbrush, then rinse thoroughly. A weekly soak in a retainer cleaning tablet like Retainer Brite helps remove buildup you can’t brush away. Always remove your retainer before eating or drinking anything other than water, and store it in its case. Retainers left on napkins at restaurants are the number one way people lose them.
For permanent retainers, you need to brush carefully around the wire at least twice a day, making sure your toothbrush bristles reach into the space between the wire and your teeth. A floss threader or water flosser makes cleaning between bonded teeth much easier. Avoid very hard or chewy foods that could snap the wire loose.
If Your Retainer Breaks or Gets Lost
Contact your orthodontist right away. This isn’t something to put off for a few weeks. Teeth can shift meaningfully in just days, especially if you’re still in the first year after braces. The sooner you get a replacement, the better the chance it will still fit without needing additional adjustment. If you have an old retainer from a previous set, wearing it temporarily may help hold your teeth in place until you can get a new one, but check with your orthodontist first since an ill-fitting retainer can do more harm than good.
Budget for replacements over time. Clear and Hawley retainers need replacing roughly once a year. Permanent retainers last about two years on average. Costs vary by provider and location, so ask your orthodontist about replacement pricing before you leave treatment so there are no surprises later.
