The day the brackets come off usually feels like the finish line, but the teeth are still settling at that point. Retention is the stage that decides whether the result holds, and for most people it carries on, at least part time, for years. It sounds like a big ask. In practice it soon shrinks to a habit that takes about as long as brushing.
Teeth keep moving after the brackets are gone
Braces move teeth by slowly remodelling the bone around them. When the active part of treatment ends, the gum fibres attached to each tooth still carry some memory of the old position, and the bone needs months to firm up. During that time, teeth can drift back toward where they started with surprising speed.
There is also a second, slower kind of change that has nothing to do with braces. Teeth tend to shift a little throughout adult life, and the lower front teeth in particular often become more crowded with age, even in people who never had orthodontic treatment. A retainer works against both of these. That is why many dentists and orthodontists now treat retention as open ended rather than something with a fixed end date. Our article on whether teeth shift without a retainer looks at that drift in more detail.
A routine that gets lighter after the first months
For a removable retainer, a common pattern is close to full time wear at first, coming out only for meals, drinks other than water, and cleaning. Once the teeth have settled, which is often a matter of months, most people move to wearing it overnight. The exact schedule depends on how much the teeth were moved and on your dentist's advice, so follow the plan you were given rather than a general rule. Our guide to retainer types and wear times sets out the common timelines.
Night wear tends to be the long term arrangement. Some people eventually wear it a few nights a week, but only once their dentist has checked that the teeth stay put with less wear.
Fixed wires and removable trays each have trade-offs
A bonded wire behind the front teeth
A fixed retainer is a thin wire glued to the inside surfaces of the front teeth. It works around the clock without you having to remember anything, and nobody can see it. The catch is cleaning. Plaque collects along the wire, so you need floss threaders or small interdental brushes to clean underneath it. The bonding can also come loose without you noticing, which is one reason to have it checked at each routine visit.
Clear plastic trays
These look like thin, clear aligners and are hard for others to spot. They come out for eating and cleaning, which makes hygiene easier, but they rely on you wearing them and they can split or warp over time, especially if they are chewed on or left somewhere hot.
Wire and acrylic plates
This older style has a metal wire across the front teeth and an acrylic plate against the palate. It is sturdy and can be adjusted, though it is more visible and some people notice it affects their speech for the first few days.
Some people end up with both: a bonded wire plus a removable tray worn at night as backup. Your dentist or orthodontist will suggest what suits your bite.
Looking after the retainer itself
A common way to lose a removable retainer is to wrap it in a napkin while eating out and throw it away by accident. Getting into the habit of putting it straight into its case avoids that.
Rinse a removable retainer whenever you take it out, and brush it gently once a day with a soft brush and cool or lukewarm water. Hot water can distort the plastic, and regular toothpaste is slightly abrasive, so a mild unscented soap is a better choice. Brush your own teeth before putting it back in, otherwise food and plaque sit trapped against the enamel all night. Our step by step guide to cleaning a retainer or night guard covers soaking and storage. If you also grind your teeth, note that a retainer is not built to take that load; the differences between a night guard and a retainer are worth knowing.
A tight fit is an early warning
If you skip a few nights and the retainer then feels tight, the teeth have already started to move. Going back to regular wear will often ease them back over several days. If it will not seat fully, or it rocks, stop forcing it and book a check, because pushing a poorly fitting retainer into place can do more harm than good.
A cracked, warped or missing retainer should be replaced promptly, since noticeable movement can happen within weeks. A replacement can often be made from a digital scan of the teeth, which avoids impression trays.

Common questions
Can I eat with a retainer in?
Take a removable retainer out to eat, then clean your teeth before it goes back in. A bonded wire stays in place, so go easy on very hard or sticky foods that could loosen it.
Will a retainer change how I speak?
Some people notice a slight lisp for the first few days, mostly with wire and plate styles. It usually fades as the tongue adapts.
Is it ever safe to stop?
Some movement is likely whenever retention stops, and there is no age at which teeth become fully stable. Whether a reduced schedule suits you is a decision to make with your dentist after checking how your teeth respond.
Getting a retainer checked or replaced
If a retainer no longer fits, has broken, or you have lost it, it is worth acting before the teeth shift. Our team can check the fit, look at a loose bonded wire and arrange a replacement. Learn more about our general dental care or see what is available on our offers page.
