5 habits that stain your teeth (and easy fixes)

Enamel is translucent. The dentin underneath is yellowish, and anything that clings to enamel makes the yellow more visible. Tannins in chai, coffee and red wine, plus tar from smoking, bind to plaque and harden into tartar — which is why stains often cluster near the gumline.

The top five culprits we see in Indiranagar: (1) Frequent masala chai or filter coffee without rinsing, (2) Sipping cola or iced tea through the day, (3) Betel or tobacco use, (4) Skipping six-month scaling so plaque calcifies, (5) Brushing too hard with abrasive charcoal pastes that scratch enamel and make it stain faster.

A professional cleaning reverses most extrinsic stains safely. Ultrasonic scaling pops tartar off, airflow polishing blasts away surface pigments with glycine powder, and a gentle paste polish restores gloss. It takes about 40 minutes and is not whitening — it restores your natural shade.

If you want lighter than natural, whitening gel lightens the internal shade 2–5 tones in the same visit. We always do a sensitivity test first and use calcium-enriched gel. For home maintenance, rinse with water after chai, wait 30 minutes before brushing after acidic drinks, and replace abrasive pastes with a low-RDA fluoride toothpaste.

Pro tip from Dr. Ananya: keep a small bottle of water at your desk and swish after every coffee. It is the cheapest anti-stain habit and also helps with dry mouth in our Bengaluru summers.
