What are the miswak benefits for teeth?
A miswak (siwak) is a twig, usually from the Salvadora persica tree, whose frayed end works as a brush. A 2022 review of small, short-term trials in adults found miswak used alone reduced plaque and gum inflammation about as well as a toothbrush, and more when added to brushing. It does not replace fluoride toothpaste. Our dentists at Creative Arts in Dubai suggest using it alongside twice-daily brushing.

Miswak benefits for teeth: what is a miswak and how does it clean?
A miswak, also called siwak or arak stick, is a short length of root or twig, most often from the Salvadora persica tree. When the bark is peeled back from one end and the wood is chewed, the fibres separate into a soft bundle of natural bristles. Those bristles scrub plaque off tooth surfaces in the same way a toothbrush does: the cleaning is mainly mechanical.
The plant itself has been studied for natural compounds, and laboratory work has looked at its effects on mouth bacteria. For patients, what matters most is the clinical question: does it remove plaque and calm the gums in real mouths? That is where the evidence below is most useful.
Miswak is also part of daily religious practice for many Muslims, which is why people in Dubai often ask whether it can take the place of a brush. Its use during fasting has its own considerations, covered in our guide to oral hygiene while fasting.
Does miswak clean as well as a toothbrush?
A 2022 systematic review and meta-analysis in the Journal of Ethnopharmacology pooled trials of miswak in adults. In those small, short-term studies, miswak used on its own reduced plaque and gingivitis to a level comparable with a toothbrush, and miswak used in addition to toothbrushing reduced plaque and gingivitis significantly more than brushing alone.
Two cautions keep this in proportion. First, the trials were small and short, so they say little about decay or gum health over years. Second, cleaning surfaces is only half of decay prevention; the other half is fluoride, and a plain miswak does not give you the fluoride dose of a fluoride toothpaste. The World Health Organization encourages twice-daily brushing with fluoride toothpaste for this reason.
The practical conclusion is simple: a miswak is a good cleaning tool and a sensible addition during the day, but your morning and night routine should still include a brush and fluoride toothpaste, plus cleaning between the teeth.
Miswak or toothbrush: how do they compare?
How the two tools differ in everyday use. Most people get the most from using both.
| Question | Miswak | Toothbrush with fluoride toothpaste |
|---|---|---|
| Removes plaque from tooth surfaces | Yes, in short trials comparable with a brush | Yes |
| Delivers fluoride against decay | Not in a meaningful dose | Yes, the main source of fluoride for most people |
| Reaches between teeth | No | No; floss or interdental brushes are needed |
| Cleans around braces or bridges | Poorly | Better, especially with small specialist brushes |
| Use away from a sink | Easy, no water or paste needed | Needs water and toothpaste |
| Risk if used too hard | Can wear gums at the neck of the teeth | Same, especially with hard bristles |
Whichever tool you use, cleaning between the teeth once a day is still needed.
How do you use a miswak correctly?
Technique matters as much as the stick. A few steps get the most from it while protecting your gums:
- Prepare a short brush. Peel back or cut away about a fingertip's length of bark and chew the exposed end gently until the fibres separate into soft bristles.
- Brush, do not scrub. Hold it like a pen and move the bristles gently over every surface, angled towards the gum line, using short strokes rather than hard sideways sawing.
- Work around the whole mouth. Outer, inner and chewing surfaces of each tooth, top and bottom. The inner surfaces of the lower front teeth and the back molars are the areas most often missed.
- Refresh the bristles. When the fibres become splayed or discoloured, trim them off and chew a fresh end.
- Keep it clean and dry. Rinse it after use and store it somewhere clean and airy rather than in a damp, closed pouch. Replace it when it dries out or no longer forms soft bristles.
For the brushing technique that miswak use should complement, see our guide on how to brush your teeth properly.
Can miswak whiten teeth?
A miswak can remove fresh surface staining from tea, coffee and food in the same way any brushing does, so teeth can look brighter once plaque and new stain are cleaned off. It does not bleach teeth or change their natural colour, and it cannot lighten crowns, veneers or fillings.
Scrubbing harder in the hope of whitening does not help. It mainly wears the gum line, and receding gums show the yellower root surface, which makes teeth look darker. If your concern is colour, our cleaning vs whitening guide explains which one you need, and a professional cleaning removes established stain that no stick or brush can shift.
Is miswak safe with veneers, braces or receding gums?
- Veneers and crowns: gentle use is fine. The concern is not the porcelain but the edge where the veneer meets the tooth and gum, which needs careful, gentle cleaning and a fluoride toothpaste. Avoid levering or biting on the stick with front teeth that have veneers.
- Fixed braces: a miswak cannot clean properly around brackets and under the wire, where plaque builds up fastest. Use an orthodontic or interdental brush as your main tool; a miswak can be an extra between meals.
- Receding gums or sensitive roots: exposed roots are softer than enamel. Use very light pressure, no sideways sawing, and keep a fluoride or sensitivity toothpaste in your routine.
- Implants and bridges: the area under a bridge and around implant crowns needs floss, interdental brushes or a water flosser that a miswak cannot replace.
If you are unsure whether your technique is wearing your gums, a check-up can show early signs of brushing damage before it causes recession.
Use it as a partner, not a replacement
The routine with the strongest evidence behind it: brush twice a day with fluoride toothpaste, clean between the teeth once a day, and use a miswak during the day if you like it. Spit out after brushing at night rather than rinsing, so the fluoride stays on your teeth.

A miswak cleans teeth; it does little for the coating on the tongue, which is a common source of morning breath. Our guide to tongue scraping and tongue cleaning covers that step. If you are deciding between brushes, the electric vs manual toothbrush guide compares them, and our guide on whether you should brush right after eating explains why timing matters after acidic food and drinks, whether you use a brush or a miswak.
Toothpaste choice matters too, because that is where most of your fluoride comes from; see how to choose a toothpaste.
