Lemon's high acidity is the primary reason your teeth might hurt after consumption. The citric acid in lemons attacks your tooth enamel, the protective outer layer. This acidic attack can cause several issues leading to tooth pain.
How Lemon Juice Damages Teeth
- Enamel Erosion: The acid in lemons wears away the enamel over time. This exposure of the dentin (the layer beneath the enamel) causes sensitivity to temperature and acidic foods like lemons. (Dentists at Pymble, Ethos Orthodontics, StoneCreek Dental Care)
- Tooth Sensitivity: As the enamel erodes, the dentin's microscopic tubules are exposed. These tubules lead directly to the tooth's nerves, making them highly sensitive to acids and temperature changes. (Quora)
- Increased Risk of Cavities: Enamel erosion weakens the teeth, making them more susceptible to decay and cavities.
Other Factors Contributing to Pain
While lemon's acidity is the main culprit, pre-existing conditions can exacerbate the pain:
- Existing Tooth Sensitivity: Individuals with already sensitive teeth will experience a more pronounced reaction to lemons. (Pleasant Plains Dental)
- Canker Sores: High acidity can contribute to the formation of small canker sores, further increasing discomfort. (Prince View Dental)
Minimizing Tooth Sensitivity After Eating Lemons
- Neutralize the acid: Rinse your mouth thoroughly with water after consuming lemons to help neutralize the acid. You can also drink milk or eat cheese; these foods help to remineralize your teeth. (Reddit)
- Avoid brushing immediately: Brushing immediately after consuming acidic foods can further damage the enamel. Wait at least 30 minutes before brushing. (StoneCreek Dental Care)
- Use fluoride toothpaste: Fluoride helps strengthen enamel and protect against decay.
- Limit consumption: Moderating your lemon intake can significantly reduce the risk of enamel erosion and tooth sensitivity.
