Gul, Manjan, Datun or Charcoal: Which Traditional Tooth-Cleaning Habits Actually Harm Your Teeth?
In Bihar, teeth are cleaned in many traditional ways — neem datun, tooth powders (manjan), charcoal, salt, and sadly also gul and gudakhu. Some are harmless; some quietly cause lasting damage. As dentists, here is our honest, practical verdict on each.
Gul and gudakhu — stop today
Let us be very direct: gul, gudakhu and tobacco-based "dental" pastes are smokeless tobacco. Rubbing them on the gums every morning is not cleaning — it is a daily dose of a cancer-causing substance held against the most vulnerable tissue in your mouth. They cause gum recession, staining, and a serious risk of oral cancer. There is no safe amount. This is the one habit to end immediately.
Charcoal, ash, brick powder and salt — too abrasive
These feel like they "clean" because they are rough and scrub hard. The problem is exactly that roughness. Enamel — the hard outer shell of the tooth — is precious and does not regenerate. Years of abrasive scrubbing wear it thin, making teeth look more yellow (the dentine shows through), feel sensitive to cold, and become more prone to decay at the worn areas.
Tooth powders (manjan) — read the label
Many commercial manjans are very abrasive and some contain tobacco. A few are reasonable. The safest choice for nearly everyone is a fluoride toothpaste, which cleans gently and actively protects against cavities — something no traditional powder does.
Neem datun — fine, with care
A fresh, soft neem twig used gently is not harmful, and neem has mild antibacterial properties. Two cautions: do not use it like a saw (hard scrubbing damages gums), and remember it provides no fluoride, so it does less to prevent decay than fluoride toothpaste.
What actually works — the simple, proven routine
- A soft toothbrush with fluoride toothpaste, twice a day, especially at night.
- Clean gently in small circles for two minutes — pressure does not equal clean.
- Clean between the teeth once a day.
- Avoid all tobacco-based products completely.
- A professional cleaning every six months.

Frequently Asked Questions
Is gul (tobacco tooth powder) safe?
No. Gul, gudakhu and similar tobacco-based dental products are a form of smokeless tobacco. Applied to the gums daily, they cause gum disease, staining and a raised risk of oral cancer. Despite being marketed for 'dental' use, they are among the most harmful things you can put in your mouth — stop completely and switch to fluoride toothpaste.
Is charcoal or brick powder good for whitening teeth?
No. Charcoal, ash, brick powder and salt are highly abrasive. They may make teeth look brighter at first by scrubbing the surface, but over time they wear away the protective enamel, exposing the yellow dentine underneath and causing sensitivity. The damage is permanent — enamel does not grow back.
Is using a neem datun acceptable?
A fresh neem twig used gently has mild antibacterial properties and is not harmful in itself, and many people use it safely. However, it does not deliver fluoride and is often used with too much force. For most people, a soft toothbrush with fluoride toothpaste twice a day gives more reliable protection against cavities.
