Answer :

Smoking decreases the level of bad bacteria in your mouth.
Smoking raises your risk for gum disease because more bacterial plaque is produced, and gums are slower to heal from infection. Smoking also stains your teeth, stinks up your breath, interferes with your taste buds and leads to tooth sensitivity.

Brush your tongue at least twice a day.

Tongue brushing can get rid of bacteria trapped in your tongue tissue, which is made up of tiny surface bumps called papillae. Plus, tongue brushing freshens your breath. It’s also a good idea to inspect your tongue once a week. Keep on the lookout for lumps or sores, which may be a sign of disease and should be reported to your dentist.

None of the above
Acidic drinks like orange juice and red wine can erode enamel, and the metal in mouth piercings can also wear enamel away. “Enamel erosion is the new big buzzword in dental hygiene, because it’s something that we’re seeing a really big wave of,” says dental hygienist Julie Linzel in Charlottetown, P.E.I.  Her recommendation? Clean your teeth at least 20 minutes after eating. That gives your saliva time to neutralize the acid.

Avoid putting a spoon in baby’s mouth that’s been in your own mouth.
“You can actually transfer bacteria that causes decay,” says Linzel. If you’re testing the temperature of your baby’s food, use a separate spoon – and no double-dipping. As for cleaning your baby’s gums and new teeth, at this age (under a year) you should use a wet washcloth or gauze rather than a brush.
