Enamel erosion's quiet causes — what's wearing your teeth that you didn't know.

Cavities have symptoms. Erosion mostly doesn't, until edges go translucent and the tooth looks shorter than the photograph from five years ago.

What erosion looks like ¶

• Front teeth edges become slightly see-through
• Bite surfaces of molars look cupped or dished
• A glossy, almost polished surface on the front faces
• Cold or sweet sensitivity emerges
• Older fillings start to protrude above the surrounding tooth (the tooth shrank around them)

The acid sources most adults overlook ¶

Sparkling water. Carbonic acid, pH ~5. Drunk daily with lemon, the pH drops to ~3. Brushing immediately after dramatically accelerates wear.

Sports drinks. pH 3.5 with added sugar and citric acid — the worst combination. The "rehydration" framing has obscured the chemistry.

Acidic fruits. Daily oranges or pomegranates are fine; daily lemon water on an empty stomach with a brush 10 minutes later is not.

GERD / silent reflux. Stomach acid is pH 1–2. If acid rises while you sleep, it sits on the lingual side of upper front teeth for hours. The lingual surface looks worn well before the labial side does — a giveaway sign your dentist can spot.

Bulimia or frequent vomiting. Lingual surface erosion. Often the first medical sign before the patient discloses it.

What you can do today ¶

• Wait 30 minutes after acidic food/drink before brushing. The pellicle needs time to re-stabilize over the softened enamel.
• Sparkling water with a meal, not between. Saliva is at peak then; it buffers acid.
• End citrus with cheese, paneer, or milk — calcium phosphate immediately re-mineralizes.
• Drink acidic drinks quickly, not sip slowly over an hour. Long contact = more erosion.
• Straw helps for sodas, less for hot drinks (you don't straw a chai).

What to ask your dentist ¶

If you've noticed any of the visible signs above, a 10-minute dental exam can stage the wear. Early erosion is conservatively treatable with remineralizing varnishes and behaviour change. Late erosion needs restorations.

A glass of plain water after the lemon is the cheapest dental insurance.

Whitening on eroded enamel ¶

Don't. Peroxide on softened enamel deepens the wear faster and triggers extreme sensitivity. Stabilize erosion first (3-6 months of behaviour change + fluoride or hydroxyapatite varnish), then consider an at-home course.

Erosion is mostly preventable. Mostly self-inflicted.
