If You Do This While Drinking Water, You Could Be Damaging Your Teeth

Dentists warn that damage from this common habit could be irreversible.

Tooth enamel is the hardest substance in your body—it's even stronger than your bones. Even so, your teeth have their fair share of adversaries. Biting your nails, sipping on lemon water, and chewing through a bag of hard candies are sure to mess with your chompers. Dentists have also sounded the alarm about another common practice that could cause irreparable damage to your teeth. Read on to find out which habit you have to kick to save your smile, and for more dental hygiene don'ts, This Is the Absolute Worst Time to Brush Your Teeth, Dentists Say.

Chewing ice can cause irreversible damage to your teeth.

Chewing the ice in your drink may seem like a harmless habit—after all, it's just water—but dentists warn that doing so could lead to severe damage. "It can cause all sorts of problems, including cracked or chipped teeth and damage to the enamel, which could lead to future tooth sensitivity and pain," says Steven Barefoot, DDS, a dentist at DentaQuest. Although these may not seem like major issues, they're largely permanent.

"The damage resulting from chewing ice is not reversible in adults, since enamel does not grow back," says Joseph Salim, DMD, founder of Sutton Place Dental Associates. "Once damaged, the only solution to chipped teeth is veneers, dental bonding, or fillings."

It can also make your teeth more sensitive to hot or cold food and drink.

Sometimes when you bite into an ice cream cone or have a hot cup of tea, you experience a slight twinge of pain due to the abrupt change in temperatures. Dentists warn that if you chew on ice often, you could damage your enamel to the point that this becomes a more frequent occurrence. "As a result of enamel being damaged, both cold and hot foods may cause sharp or persistent pain," Salim explains.

Your gums can recede if you chew on ice.

Gum recision is irreversible and can lead to a host of other issues. "Your gums can recede as a result of the pressure from chewing on hard ice regularly," Salim says. In addition to the fact that receded gums are often thought of as an undesirable cosmetic annoyance, gum recession can also cause more tooth sensitivity. "As your gums no longer protect your dental roots, you will feel hot and cold temperatures much more sharply," he adds.

And your teeth can crack.

Although your teeth are very strong, they're sometimes no match for ice. "Ice is an incredibly strong material, and so is enamel. By repeatedly chewing on ice, you can cause small fracture lines in your teeth," Salim says. "You may not notice it today or tomorrow, but if you chew ice frequently, your teeth will weaken and risk fracturing one day."

Your teeth are "porous and microscopic cracks do form. If ice is chewed, the enamel gets slightly brittle and the small, microscopic cracks expand and contract with the cold and the warming in the mouth," explains former dentist Joseph Varno, DDS. The cracks aren't all you have to worry about. "Bacteria are smaller than the cracks and love to hide there forming colonies. Chromogenic bacteria leave a trace we can see with the naked eye in that the crack appears brown or black," he adds.

If you chew on ice, you could have more frequent toothaches.

Your enamel functions as a barrier for your teeth, Salim notes. When that barrier is diminished, you'll hit dentin, just below the enamel, which is softer and more prone to dental decay. The ostensibly harmless habit "can end up irritating the soft tissue or the pulp, inside a tooth, and toothache can follow," Salim says, offering yet another reason why chewing ice is a habit you need to ditch.
