There are times in life when you want to make sure to make a good impression. Whether you're going on a first date or networking with people at a work function, you want to look your best. Your smile is an important part of your appearance. Here are four dental hygiene tips that can help you make a good first impression:

1. Get your professionally teeth whitened.

Your teeth naturally become discolored as you age due to your enamel thinning and the underlying dentin showing through. Even if you take excellent care of your teeth, it's not unusual for them to begin to look a little yellow. Your smile is one of the first things people notice about you, so you want to make sure it looks its best. Take care of tooth discoloration by having your teeth professionally whitened.

While there are over-the-counter options available, your dentist will be able to tailor your tooth whitening treatment to suit your needs. You'll get an even, natural-looking whitening that will make your teeth look beautiful. Teeth whitening services may make your teeth temporarily more sensitive, so you might want to invest in sensitive teeth toothpaste for the days following your treatment.

2. Remember to floss.

No one wants to talk to someone with a piece of spinach stuck between their teeth. Having food caught between your teeth in public can be embarrassing for you and distracting to the people you're talking to. Prevent this by excusing yourself to take a quick look in the mirror after eating a meal. You should be flossing once a day for good dental hygiene, but it's also a good idea to keep some floss with you just in case you need it during the day.

3. Keep your breath fresh.

Bad breath is caused by bacteria and the foods you eat, according to WebMD. Proper oral hygiene should take care of most of your bad breath problems. Remember to brush your teeth and gargle with mouthwash before an important event. Try to avoid foods with strong smells, like onions, since these odors can linger on your breath for hours. When in doubt, chew a piece of sugar-free gum before meeting any important people.

4. Smile.

Finally, don't forget to smile. Smiling makes you look friendly and approachable, and that's the best way to make a good impression on other people. If you've followed all these tips, you can feel confident that you have a beautiful, fresh, clean smile. Don't be afraid to show off those pearly whites!
