Will taste buds repair themselves after eating a lot of ice for several months?

In general, taste buds have the ability to regenerate and repair themselves. Here's some general information on the topic:

Taste Bud Lifespan: Each individual taste bud has a lifespan of about 10-14 days, after which new cells form to replace the old ones. This means that if your taste buds are damaged for any reason, there's potential for them to heal or be replaced by new taste buds over time.
Eating Ice: Eating ice in and of itself should not cause damage to taste buds. However, if the ice is extremely cold or if you are chewing on it vigorously, there's the potential for mechanical damage or "frostbite" type injury to the tongue, which could potentially affect the taste buds.
Anemia and Ice Eating: The act of craving and eating ice (or pagophagia) can sometimes be associated with iron-deficiency anemia. If someone is anemic and craves ice, it's crucial to address the underlying iron deficiency rather than just the symptom of ice eating. Treating the anemia may reduce or eliminate the ice craving. The link between ice craving and anemia is not completely understood, but it's a recognized phenomenon.
Other Causes of Altered Taste: Factors other than ice eating can affect taste, including certain medications, infections, other medical conditions, smoking, and more. If you or someone you know is experiencing a change in taste, it's essential to consider these potential factors as well.

In general, if there is no significant injury to the tongue and if other potential causes of taste disturbances are ruled out, taste buds should continue their natural regeneration process.

Hope this helps!
