Why Hygiene Matters More During Treatment

Braces and, to a lesser extent, aligners create additional surfaces and small gaps where food particles and plaque can become trapped more easily than around naturally aligned, unobstructed teeth. If not managed carefully, this can lead to visible white or brown decay spots around the brackets, known as demineralisation, as well as increased gum inflammation throughout treatment.

Because orthodontic treatment often lasts a year or more, even small daily lapses in hygiene can accumulate into significant problems by the time the appliance is removed. Establishing a thorough and consistent routine from the very first week of treatment makes a substantial difference to your long-term oral health and the appearance of your teeth once treatment is complete.

Brushing Technique for Fixed Braces

When brushing with fixed braces, angle the bristles both above and below each bracket to clean the areas where the bracket meets the tooth surface, since plaque tends to accumulate most heavily in these junctions. Take extra time around each tooth rather than rushing through a standard two-minute brushing routine, as the additional surfaces created by the brackets require more thorough attention than usual.

An interdental brush, small enough to fit under the archwire, is invaluable for cleaning between brackets and around the gumline where a standard toothbrush cannot reach effectively. Using this tool daily, in addition to regular brushing, significantly reduces plaque buildup in the hard-to-reach areas around your braces.

Flossing with Braces

Traditional flossing is more challenging with fixed braces because the wire blocks the floss from passing directly between teeth in the usual way. Floss threaders, which help guide the floss under the archwire before it is pulled through between the teeth, make this process manageable, though it does take more time and patience than flossing without an appliance.

Water flossers offer an alternative that many patients with braces find easier and quicker to use daily, directing a stream of water between teeth and around brackets to dislodge trapped food and plaque. While not a complete replacement for mechanical cleaning with floss or interdental brushes, a water flosser can be a valuable addition to your daily routine during orthodontic treatment.

Cleaning Aligners and the Teeth Beneath Them

Because aligners are removable, you should brush and floss your teeth thoroughly before reinserting each tray, ideally after every meal or snack, to prevent food particles and bacteria from being trapped against your teeth for extended periods. This is one of the significant hygiene advantages of aligner treatment compared to fixed braces.

The aligners themselves also need daily cleaning using a soft toothbrush and lukewarm water, or a dedicated cleaning solution, to prevent a buildup of plaque and bacteria on the plastic surface, which can otherwise contribute to bad breath and an increased risk of decay against the teeth.

Dietary Habits That Support Good Hygiene

Reducing frequent snacking, particularly on sugary or starchy foods, helps limit the number of times your teeth are exposed to the acid produced by bacteria feeding on food debris throughout the day. This is especially relevant during orthodontic treatment, when the additional surfaces of brackets or the closed environment beneath aligners can prolong this exposure if snacking is frequent.

Drinking plenty of water throughout the day, particularly after meals when brushing is not immediately possible, helps rinse away food particles and reduce the acidity in the mouth. Scheduling regular professional cleanings with our hygiene team throughout your orthodontic treatment also provides an important extra layer of plaque and tartar removal that home care alone cannot always achieve.

Questions patients ask us

How often should I brush my teeth while wearing braces?
Brushing after every meal or snack is ideal during orthodontic treatment, given the additional food-trapping surfaces created by the brackets and wires. At a minimum, thorough brushing morning and night, combined with interdental cleaning, is essential to prevent decay and gum inflammation around the appliance.
What white or brown spots might appear near my brackets mean?
These marks often indicate early demineralisation of the enamel, caused by plaque accumulation around the brackets over time. This is a sign that hygiene needs to be improved promptly, as continued plaque buildup in these areas can progress towards actual decay if not addressed.
Is a water flosser enough to keep my braces clean?
A water flosser is a helpful addition to your routine but works best alongside, rather than instead of, thorough brushing and interdental brushing or floss threading. Combining these methods provides the most comprehensive removal of plaque and food debris around brackets and wires.
How often should I see the hygienist during orthodontic treatment?
Most patients benefit from professional cleanings every three to six months during orthodontic treatment, though your specific interval may be adjusted based on how well you are managing home care. Regular hygiene visits provide an important safety net alongside your daily brushing and cleaning routine.
