Question

How long do the teeth stay stained after just chewing one nut?

Community Answer

They will only stay stained for a few hours. You must brush your teeth after chewing them and rinse plenty. The staining effect only comes after prolonged chewing.

Question

Will dried betel nut provide the same effect as fresh betel nut?

Community Answer

It usually does, but it would be unsafe to buy the product without researching it first, as you never know what people have done to preserve it over time.

The Betel Nut is a proven carcinogen . While relatively uncommon in other countries, oral Squamous Cell Carcinoma (SCC) is the most common malignant cancer in Papua New Guinea, with an average 47% mortality within 5 years of diagnosis. One study shows chewing Betel Nut increases the risk of oral cancer 28-fold. Betel Nut also comes in convenient tea bag-like pouches, but the carcinogenic effect of these has not been tested. Use Caution.

Do not visit public betel nut markets alone if you are a tourist or an expatriate. Go with a local guide because public markets, especially in Port Moresby, have quite a lot of rascal activity.

Betel nut is often compared to tobacco. It can be very addictive and habit-forming. In many places in PNG you will find “no betel nut” signs that are similar to “no smoking signs.”
