How to Clean Between Teeth When You Have Braces

By Renew Dental Clinic·Published on 26 August 2026

Getting braces means committing to two things simultaneously: the treatment itself, and the hygiene that protects your teeth through it. The second one is harder — and far more consequential if ignored — than most patients are warned about at the start.

Brackets and wires create an entirely new landscape in the mouth. Every bracket surface is a plaque trap. Every wire is a barrier between the toothbrush and the gumline. Every space between the bracket base and the tooth surface is a location where bacteria can establish themselves and stay undisturbed for days.

The patients who finish orthodontic treatment with genuinely beautiful results — aligned teeth, healthy gums, no white spots — are the ones who adapted their oral hygiene to this new landscape from day one. Those who didn't adapt sometimes remove their braces to discover new decay or decalcification marks around every bracket — permanent damage to enamel that wasn't there when treatment started.

Why Braces Make Oral Hygiene So Much Harder

Before braces, you're cleaning teeth. After braces go on, you're cleaning teeth plus the hardware attached to them.

Each bracket has four corners and a base surface that sits against the tooth. The wire threads through every bracket. The combination creates surfaces that a standard toothbrush cannot reach with normal technique, and spaces between which food and plaque accumulate in ways they wouldn't on unobstructed teeth.

The consequences of inadequate cleaning during orthodontic treatment are well documented

White spot lesions. The most common complication of poor hygiene during braces. Plaque accumulating around brackets produces acid continuously, which dissolves the mineral content of the enamel immediately surrounding the bracket. The result is a permanent white, chalky mark left on the tooth surface where the bracket was — visible the moment the braces come off. These marks cannot be fully reversed; they can only be managed with remineralisation treatments, microabrasion, or composite masking.

Gingivitis and gum inflammation. The bacteria that accumulate between the wire and the gumline drive chronic gum inflammation throughout treatment. Patients with consistently poor hygiene during braces frequently have puffy, swollen gum tissue that may not resolve immediately after treatment ends.

Decalcification and cavity formation. In more severe cases, the enamel doesn't just lose surface mineral — cavities form at the bracket margins. Discovering active decay around a bracket mid-treatment disrupts the orthodontic plan and adds significant treatment complexity.

None of this is inevitable. It's entirely preventable with the right approach and the right tools.

The Tools That Actually Work

Orthodontic Toothbrush (V-Shaped Bristles)

Standard round-headed toothbrushes can be used with braces, but orthodontic toothbrushes — designed with V-shaped or bi-level bristles — are specifically engineered for the bracket-and-wire environment. The V-shaped bristle pattern allows the longer outer bristles to reach the tooth surfaces above and below the bracket while the shorter inner bristles clean around the bracket face itself.

An electric toothbrush on a moderate setting is also effective and is often preferred by patients because it does more of the technique work automatically — particularly useful in the first weeks of treatment when the brackets and wire feel strange and awkward to navigate around.

Interdental Brush (Proxabrush)

For cleaning between brackets and under the archwire, the interdental brush — a small bottle-brush-shaped implement — is the most effective tool available. It reaches where a standard toothbrush simply cannot go.

The technique: insert the brush gently under the archwire, then work it between the bracket bases on adjacent teeth. Move it back and forth gently to displace plaque from the bracket sides and the tooth surfaces adjacent to the wire. The brush should fit without forcing — if it won't go without significant pressure, try a narrower size.

Interdental brushes come in different diameter sizes. During orthodontic treatment at Renew Dental Clinic, Sector 47, Noida, Dr. Suchi Singh advises on the appropriate sizes for each patient's specific bracket spacing and arch anatomy.

Studies show interdental brushes are more effective than floss at removing plaque in the spaces around brackets and under wires. For patients with braces specifically, they're the most efficient per-minute cleaning tool for the between-bracket areas.

Floss Threader

Standard string floss cannot pass under the archwire without a threader. A floss threader is a flexible, pointed plastic loop that threads the floss under the wire, allowing it to reach the contact point between teeth and the gumline beneath — areas the interdental brush doesn't access as well.

The process: thread the floss through the threader loop, pass the pointed end under the archwire, pull the floss through until you have enough to work with, then clean between the two adjacent teeth in the standard C-shape technique, reaching below the gumline on each tooth. Remove the floss by pulling it out from the side (not back through the wire), and repeat at each contact point.

This process is slow — threading floss for a full mouth takes 15 to 20 minutes when you're learning. Most patients do a full floss thread once daily (before bed is practical) and use interdental brushes as the faster between-meal option.

Superfloss (Pre-Threaded Floss)

Superfloss (Oral-B and similar brands) is pre-cut floss with three sections: a stiffened end that passes under the wire without a threader, a spongy floss section that cleans around brackets, and standard floss for between-tooth cleaning. It simplifies the threading process significantly and is popular among orthodontic patients.

Superfloss segments are available in most pharmacies and are more convenient than a separate threader and floss combination for daily use.

Water Flosser

A water flosser used at medium pressure effectively dislodges food from between brackets and under wires, and irrigates the gumline. It's not as physically disruptive of plaque as mechanical flossing or interdental brushing — it flushes rather than scrapes — but it's dramatically better than no interdental cleaning.

For patients who find threaded flossing too time-consuming to do consistently, a water flosser as the primary interdental cleaning method is significantly better than the alternative of skipping interdental cleaning altogether. The consistency of use matters more than the theoretical superiority of any single method.

The Correct Brushing Sequence With Braces

The order matters. Interdental cleaning before brushing clears debris from between the brackets and under the wires, allowing the toothbrush to access surfaces that were previously blocked.

Step 1: Rinse with water to dislodge loose food particles.

Step 2: Use the interdental brush under the archwire and between brackets — work through the full mouth, upper and lower.

Step 3: Floss (or superfloss) through the contact points at least once daily, ideally before the brushing session.

Step 4: Brush with an orthodontic or soft-bristled toothbrush using the modified technique described below.

Step 5: Rinse with an antimicrobial or fluoride mouthwash.

Brushing Technique — Modified for Braces

The standard gumline brushing technique needs adjustment with braces in place.

Hold the brush at 45 degrees to the gumline and use short circular strokes — the same technique as without braces. But add two additional angles:

Above the bracket: Angle the brush downward (for upper teeth) or upward (for lower teeth) to clean the tooth surface and gumline above the bracket. This is the space most people miss — between the bracket and the gum.

Below the bracket (at the bracket face): Hold the brush more horizontally to address the bracket face and the tooth surface between the bracket and the biting edge.

The result: you're cleaning three zones per tooth surface — above the wire, at the bracket, and below the bracket — rather than just sweeping across. Each zone gets deliberate attention.

Two minutes of brushing for a full mouth without braces. With braces, plan for 3 to 4 minutes — the additional bracket surfaces take additional time.

After Every Meal — The Brace Reality

Without braces: brushing twice daily is adequate for most adults. With braces: food gets trapped in brackets and wires after every meal, and leaving it there for hours creates sustained bacterial activity at the bracket margins.

The recommendation during orthodontic treatment is to brush after every meal — not just morning and night. This isn't necessarily a full 3-minute session each time; a 60-second focused rinse and interdental brush sweep after lunch significantly reduces the bacterial accumulation that would otherwise persist until the evening brushing session.

For patients at school or at work in Noida who can't brush after lunch: a water flosser if one is available, or at minimum a thorough water rinse to dislodge food before bacteria have time to organise around it.

Fluoride During Orthodontic Treatment

Fluoride is a particularly important protective measure during brace treatment because of the elevated risk of enamel demineralisation around brackets.

Fluoride toothpaste: Non-negotiable. Use it at every brushing session and don't rinse immediately after — let the fluoride residue work.

Fluoride mouthwash: Using a 0.05% sodium fluoride rinse daily (at a different time from brushing) adds an additional fluoride application that reaches around and behind brackets.

Professional fluoride varnish: At check-up appointments at Renew Dental Clinic, fluoride varnish applied to bracket margins provides targeted high-concentration protection at the most vulnerable areas. This is one of the most effective preventive interventions for patients undergoing orthodontic treatment.

Avoid whitening toothpastes during brace treatment. The whitening abrasives in these products clean the exposed enamel around brackets but cannot reach under the brackets themselves. When braces come off, the exposed bracket areas — protected during treatment — will be whiter than the surrounding enamel that was being whitened. The result is an inverted pattern of discolouration that's more noticeable than if no whitening was attempted at all.

Retainers — The Cleaning Continues After Braces

Once braces come off, most patients receive retainers — either removable clear retainers or fixed (bonded) retainers on the inner surfaces of the front teeth.

Removable retainers: Remove, clean with a soft brush and mild soap (not toothpaste, which scratches clear retainer surfaces), and store in a clean case when not in use. Wear as prescribed.

Fixed retainers: A thin wire bonded to the inner surfaces of the lower (and sometimes upper) front teeth. These require exactly the same threaded flossing technique as braces — floss must be threaded under the retainer wire to clean between each tooth. Neglecting to clean under fixed retainers leads to calculus buildup on the wire and the teeth it contacts, which can compromise both gum health and the retainer's long-term success.

Frequently Asked Questions

My gums bleed when I use the interdental brush — is that normal?

If hygiene has been inconsistent, the gum tissue around brackets will be inflamed and will bleed on contact. This typically improves within 2 to 3 weeks of consistent cleaning as the inflammation reduces. Heavy or persistent bleeding warrants a check-up.

How often should I clean the interdental brush itself?

Rinse it thoroughly after each use. Replace it when the bristles become bent or discoloured — typically every 1 to 2 weeks depending on use frequency.

Can I use any mouthwash with braces?

Yes — fluoride-containing mouthwashes are recommended. Avoid whitening mouthwashes for the same reason as whitening toothpastes during brace treatment.

My orthodontist is at a different clinic — should I still come to Renew Dental for check-ups?

Yes. Orthodontic check-ups monitor the tooth movement. Dental check-ups monitor tooth and gum health throughout treatment. Both are needed. Dr. Suchi Singh coordinates care with the orthodontist where needed.
