喝咖啡可能引发龋齿，这三条建议帮助你保护牙齿
现在，你很可能已经知道咖啡会让牙齿变色，但咖啡是否还会造成龋齿？有一条被疯传的推文引用了一条TikTok视频的截图，视频中，一名牙医警告观看者长期饮用咖啡的害处。
加州Facer Hales Parker牙科诊所的泰勒·黑尔斯博士表示：“从化学和技术的角度，喝完咖啡后，如果咖啡在你的牙齿上存在30分钟，就会导致龋齿。但我们发现这种情况发生的概率并不高。否则现在龋齿将变得非常普遍，因为人们会喝大量咖啡。”
虽然酸性环境可能导致牙釉质变软脱落，但人体能够自发地通过唾液中和咖啡中的酸性物质，唾液的pH值约为7至8。pH值为0意味着酸性极强，14意味着碱性极强。
黑尔斯解释称：“在喝咖啡的时候，快速喝完好于慢慢品尝，因为咖啡在牙齿上停留时间越长，就越有可能形成酸性环境。虽然咖啡在口腔中形成酸性环境大幅降低pH值的情况并不常见，但通过一些做法可以帮助改善或避免这种情况出现。”
黑尔斯分享了喝咖啡时保护牙齿的三条建议：
用吸管喝咖啡。不要让咖啡直接接触牙齿，而是使用吸管，帮助咖啡（及其酸性物质）直接绕过牙齿。吸管还能帮助避免牙齿变色。
用水漱口，冲掉咖啡。与唾液一样，水的pH值是7，既不是酸性也不是碱性。
喝完咖啡嚼无糖口香糖。黑尔斯解释称：“无糖口香糖的作用是激活唾腺。唾液增多，人体就能中和口腔环境。”你还可以吃苹果、香蕉等水果中和咖啡的酸性，但避免橙子和葡萄柚等酸性水果。
如果你喜欢在喝完咖啡后刷牙，黑尔斯建议至少等5至10分钟。他说道：“酸性环境会软化牙釉质，如果喝完咖啡立刻刷牙，反而可能造成更多伤害。”
相反，黑尔斯建议，先用水或水果中和咖啡，然后再刷牙。这条建议也适用于其他含咖啡因的饮料，如茶、苏打水和能量饮料等。
他说道：“尽量避免饮料在牙齿上停留，使用吸管，喝完之后要中和口腔环境。”（财富中文网）

By now you’re more than likely aware of how coffee can stain your teeth, but can it cause cavities, too? According to a viral tweet, which features a screenshot from a TikTok post, a dentist warns viewers about the perils of drinking coffee for too long.
“If you look at it from the chemistry aspect, then technically, yes, coffee could cause cavities if you were sipping on your coffee and it was sitting on your teeth for about 30 minutes,” says Dr. Tyler Hales of Facer Hales Parker Dentistry in California. “But that’s not a high probability that we’re seeing. Otherwise cavities would be rampant today because of the amount of coffee people drink.”
While an acidic environment can cause teeth’s enamel to become softer and wear out, your body naturally does a good job of neutralizing the acidity from coffee with saliva, which has a pH of about seven to eight. A pH scale ranges from zero, which means it’s extremely acidic, to 14, which is very basic.
“When you drink your coffee, it’s better to drink it quicker than slower simply because the longer the coffee is on your teeth, the more of an acidic environment it’s causing,” Hales explains. “It’s very uncommon that coffee is causing the acidic environment in the mouth to lower the pH level very much, but there are things you can do to help that or to help prevent that.”
Below, Hales shares three ways to protect your teeth while drinking coffee:
Drink your coffee with a straw. Instead of having the coffee directly hit your teeth, using a straw helps the coffee (and its acidity) bypass your teeth altogether. A straw can also help prevent stains to your teeth.
Chase your coffee with water. Like saliva, water has a neutral pH of seven, which means it’s neither acidic nor basic.
Chew sugar-free gum after drinking your coffee. “What sugar-free gum does is it actually activates the salivary glands,” explains Hales. “So the more saliva you have, the more your body is neutralizing that environment.” You can also eat fruits such as apples or bananas to combat the coffee’s acidity, but avoid acidic fruits such as oranges and grapefruits.
While you may be tempted to reach for your toothbrush after drinking coffee, Hales recommends waiting at least five to 10 minutes. “That acidic environment is going to soften that enamel, so if you brush immediately after drinking coffee you could cause more damage,” he says.
Instead, Hales advises neutralizing the coffee with either water or fruit and then brushing. The same rule of thumb applies to other caffeinated beverages, such as tea, soda, and energy drinks.
“Try and prevent the amount of time the drink is on the teeth, use straws, and then neutralize the environment afterward,” he says.
