Do you feel stuck in your career? Your resume or work ethic may not be the reason you aren’t climbing the ladder to success. Although you shouldn’t judge a book by its cover, many people base their opinion about a person by the way their teeth look. People often attribute tooth discoloration to age, poor oral hygiene, and low self-esteem. While everyone’s smile darkens over the years, don’t let it hold you back from taking your career to the next level. You can invest in a bright, beautiful smile to give your career a boost.
