13 things to avoid
Drinking it extremely concentrated — more lemon means more acid, not more health benefits.

Using lemon water instead of plain water — regular water is a better everyday hydration choice.
Adding lots of sugar — this can turn a simple drink into a sugary beverage that is worse for dental health.

Ignoring tooth sensitivity — sensitivity can be a sign that your enamel needs attention.
Assuming it detoxes your body — your liver and kidneys already perform those functions.
Expecting it to melt body fat — lemon itself doesn’t provide a special fat-burning effect.

Using it as a treatment for diabetes — lemon water isn’t a substitute for diabetes treatment.
Assuming “natural” means risk-free — concentrated acidic drinks can still affect teeth and the digestive system.
Ignoring persistent symptoms — ongoing reflux, severe tooth sensitivity, or stomach pain deserves medical or dental advice.
A safer way to drink it
Use a small amount of lemon in a glass of water, drink it relatively quickly rather than constantly sipping, and rinse your mouth with plain water afterward. A straw can reduce contact with the front teeth.
