What causes teeth to chip easily?

Teeth chip more easily when the enamel intended to protect them erodes or wears, according to WebMD. Enamel is what protects a tooth from the abrasive actions of chewing, crunching and grinding.

Soft drinks and fruit juices are among the most significant culprits in enamel wear, according to WebMD. These beverages contain corrosive acids that eat away at the enamel. Diets that are high in sugars and starches also contribute to enamel wear. Low salivary flow is also a factor. Certain medical conditions, such as acid reflux and gastrointestinal problems, play a role, as do medications such as aspirin and antihistamines.
