My teeth have suddenly become very sensitive to both hot and cold, but my mouth is otherwise healthy. What could cause this?

A major cause of tooth sensitivity is root exposure. Kindly consult a dentist in person for further suggestion. We need more investigations (full mouth x-ray) to decide upon treatment. You may need cleaning along with desensitizing procedures and / or artificial enamel filling. Advance procedures can be done with laser too. Until then apply a desensitizing paste (sensodyne tooth paste) on the teeth. Wait for 10 to 15 min until you brush your teeth with the same paste. Applying it overnight will be better. Dental tips: - visit a dentist every six months for cleaning and a thorough dental check-up. Limit sugary food to avoid tooth decay. Gargle your mouth thoroughly after every meal. Scrub gently to clean your tongue with a tongue cleaner. Floss all your teeth inter dentally & brush twice daily, morning & night, up & down short vertical strokes, with ultra-soft bristles, indicator brush. Tooth brush to be changed every 2 months.
