Eating food in the middle of the night can seriously damage your teeth, experts warn.

专家警告，在午夜吃东西可严重损伤牙齿。

Midnight snacks may stick to the teeth for longer, experts suspect

Researchers have found midnight snacking ups the risk of tooth loss, regardless of the type of food that is eaten.

The Danish investigators¹ blame changes in saliva²（唾液） flow - it tends to dry up at night.

Enough saliva is important to remove food debris（碎片，残骸） from the mouth, they explain in Eating Behaviours journal.

Night nibbles³

Working with colleagues from the US, the team at Copenhagen University examined the medical records of 2,217 Danes already enrolled⁴ in a medical study.

Of these 173, or 8%, could be classed as nocturnal（夜间的） eaters - meaning they consumed a quarter or more of their daily calories after dinner or would wake up in the middle of the night at least twice a week for a little moonlight snack.

When the researchers tracked what happened to all of the study participants over a period of six years, a significant finding emerged.

The nocturnal eaters ended up losing more teeth, even after accounting⁵ for other factors such as age, smoking and sugar/carbohydrate（碳水化合物） consumption.

While dentists may not be able to stop their patients feasting in the middle of the night, Dr Jennifer Lundgren and colleagues say they should make them aware of the associated risks.

"Practitioners⁶ should be aware of the oral health implications（含义，启示） of nocturnal eating, increase screening and oral health education efforts among nocturnal eaters and make treatment referrals when appropriate（适当的） ," they say.

Professor Damien Walmsley, scientific adviser⁷ to the British Dental Association, said: "Eating at night, when the mouth is driest and any food remains⁸ in the mouth longer, accentuates⁹（强调） the impact of consuming sugary and acidic（酸性的） food and drinks.

"To minimise damage, it is important to brush teeth twice a day with fluoride（氟化物） toothpaste, with one of those brushes coming immediately before bedtime.

"Where possible, consume only water for at least an hour before the final brush of the day."
