Despite brushing twice, we may have bad breath throughout the day. How can we address this issue?

Bad breath is caused by a bunch of different reasons. If you have bad breath after regular brushing, then:

• Check if your brushing technique is correct, and that you aren’t missing any areas in the mouth.

• Make sure you don’t have any cavities.

• Ensure you’re cleaning your tongue. It’s very important.

• Check if you have tonsillitis, constant acidity or gastritis, sinusitis, etc. All of these cause bad breath.

• Ensure you’re drinking enough water. Sip water through the day. You can also add some mint leaves to the water.

Which foods generally stain teeth? Also, which foods help promote dental health?

A good rule of thumb to follow to maintain white teeth is – anything that can stain your white shirt can stain your teeth. Tea, coffee (especially black coffee), turmeric are the usual culprits in yellowing teeth. Nowadays, polishing or bleaching your teeth is quick, painless and the easiest way to brighten discoloured teeth.

Fibrous foods like apples, celery and carrots promote dental health. Also, fruits like strawberries, foods with good fats like avocados, nuts and green leafy veggies keep teeth very happy. Obviously, sugary and acidic foods like colas should be kept away from your pearlies!

Is it true that if you drink coffee or soft drinks with a straw, it could prevent discolouration?

Yes, there is some truth to this. Soft drinks and fruit juices are your teeth’s worst enemies. High in sugar and acids, they create a feast for the bacteria in your mouth. By using a straw, you’re avoiding contact between the drink and your teeth and guiding it straight to your throat, thereby minimising its effects.

Coffee isn’t actually harmful to your teeth. It does however, stain teeth. A straw could slow down development of stains.
