The best toothpaste for braces is one that contains fluoride at a standard concentration (1,450 ppm) or higher, protects against the white spots that commonly form around brackets, and avoids highly abrasive ingredients that can damage enamel. Beyond that baseline, your specific needs (gum inflammation, mouth sores, or a preference to avoid fluoride) can steer you toward particular formulas.
Why Braces Demand More From Your Toothpaste
Brackets and wires create dozens of tiny traps where plaque builds up against enamel. That plaque produces acid, and because it sits in the same spot for months, it can etch chalky white marks into the tooth surface. These white spot lesions are the single most common side effect of braces, and they can become visible in as little as four weeks after brackets are placed.
The right toothpaste works as your first line of defense. It needs to do two things well: deliver minerals that strengthen enamel faster than plaque acids break it down, and control the bacterial film that causes gum inflammation. Not every toothpaste is equally good at both.
Fluoride Concentration Matters
Standard over-the-counter toothpaste contains around 1,000 to 1,450 ppm fluoride, which is enough for most people. For orthodontic patients, though, higher-concentration options offer a measurable advantage. A Cochrane review found that patients using a 5,000 ppm fluoride toothpaste developed fewer new white spot lesions compared to those using a conventional 1,450 ppm paste. These high-strength toothpastes (sometimes labeled “prescription strength”) are available through your orthodontist or dentist and are worth asking about if you’re prone to cavities.
If you stick with a regular-strength fluoride toothpaste, it still works. The key is using it consistently, brushing after every meal, and spending extra time angling your brush above and below each bracket where plaque collects.
Stannous Fluoride vs. Sodium Fluoride
Most fluoride toothpastes use one of two fluoride types: sodium fluoride or stannous fluoride. For braces, stannous fluoride has a slight edge. A clinical trial comparing the two in orthodontic patients found that the stannous fluoride group had less plaque buildup, less gum bleeding, and about 40% fewer new white spot lesions on upper front teeth compared to the sodium fluoride group. Stannous fluoride has antibacterial properties that sodium fluoride lacks, which helps explain the difference in gum health.
The trade-off is that stannous fluoride can cause temporary surface staining on teeth, though this is cosmetic and removable at a cleaning appointment. For most people wearing braces, the gum and enamel benefits outweigh that minor downside.
Remineralizing Ingredients That Help
Beyond fluoride, certain ingredients actively rebuild weakened enamel. The most studied is CPP-ACP (casein phosphopeptide-amorphous calcium phosphate), a milk-derived compound found in products like MI Paste and Tooth Mousse. It works by delivering calcium and phosphate ions directly to the tooth surface, where they reform into the mineral crystals that make up healthy enamel.
Research on orthodontic patients found that CPP-ACP was more effective than fluoride rinse alone at reducing demineralization around brackets. White spot lesions had a significantly greater chance of fading within 12 weeks when patients used a remineralizing cream containing CPP-ACP. Some orthodontists recommend applying it as a separate step after brushing with fluoride toothpaste, particularly during the first six months after braces come off, when existing white spots are most responsive to treatment.
Hydroxyapatite Toothpaste
If you prefer a fluoride-free option, hydroxyapatite toothpaste is the strongest alternative. Hydroxyapatite is the same mineral that makes up about 97% of tooth enamel, and toothpastes containing 10% hydroxyapatite have shown remineralization and demineralization prevention comparable to fluoride toothpaste in controlled studies. The remineralization pattern differs slightly: fluoride tends to harden the outer surface layer, while hydroxyapatite produces a more even, homogenous repair through the lesion.
Hydroxyapatite toothpastes are widely available in brands like Boka and Apagard. They’re a reasonable choice for orthodontic patients who can’t use fluoride or prefer not to, though the overall body of evidence behind fluoride is still larger.
Toothpastes to Avoid With Braces
Whitening toothpastes are the biggest category to skip. Many rely on abrasive particles to scrub surface stains, and their abrasivity scores (measured as RDA, or Relative Dentin Abrasivity) can run well above the normal range of under 100. Excessive abrasion wears down enamel, increases sensitivity, and can roughen the tooth surface around brackets, making it even easier for plaque to stick. Since whitening toothpaste can’t reach the enamel hidden under your brackets anyway, you’d end up with uneven color when the braces come off.
Charcoal toothpastes fall into the same category. They tend to be highly abrasive and lack fluoride or other proven remineralizing agents. Save any whitening efforts for after your braces are removed.
SLS-Free Options for Mouth Sores
Sodium lauryl sulfate (SLS) is the foaming agent in most toothpastes. It’s generally harmless, but if you get frequent canker sores, the brackets and wires rubbing against your cheeks may already be pushing your mouth past its irritation threshold. A meta-analysis of four randomized trials found that people prone to canker sores who switched to SLS-free toothpaste experienced fewer ulcers, shorter healing times, and lower pain scores.
If you notice recurring sores during treatment, switching to an SLS-free formula (such as Sensodyne Pronamel, Verve Ultra, or Closys) can reduce one source of irritation while your mouth adapts to the hardware.
How to Get the Most Out of Any Toothpaste
The American Association of Orthodontists recommends brushing after every meal during treatment, not just twice a day. That means keeping a travel toothbrush and toothpaste with you. Use an interproximal brush (the small cone-shaped brush your orthodontist likely gave you) to clean around each bracket and under the archwire where a regular toothbrush can’t reach. Floss at least once a day, using a floss threader or orthodontic flosser to get under the wire.
After brushing, try not to rinse with water right away. Spitting out the excess but leaving a thin film of toothpaste on your teeth gives the fluoride or hydroxyapatite more contact time to absorb into enamel. If you use a CPP-ACP cream, apply it after brushing as a final step and leave it on for three to five minutes before spitting.
Rinsing your mouth with plain water after sugary drinks or snacks between brushings also helps. It won’t replace brushing, but it clears sugar from around the brackets before bacteria can convert it into acid.
