A pleasing smile, either from porcelain veneers or other means can boost confidence for many people. According to a Kelton Research study, perfect, white teeth have a direct impact on social and professional interactions. A survey of more than 1,000 people found that a healthy looking smile substantially shape people's first impression of potential spouses and employees.

The three-part study, which included simulated job interviews, suggested that more than half of the participants (58 percent) were more likely to be hired after their teeth had been whitened. The study also concluded that evaluators expressed greater interest in people with whiter teeth. Apparently, people with healthier looking teeth seem to exude more professionalism and confidence. People with whiter teeth were also perceived as more outgoing.

White beautiful teeth also convey trustworthiness and professional success. Appearance matters according to the survey. About 68 percent of people surveyed gauge a person's professional success and failure by his/her appearance. People with healthy looking teeth were considered more successful, regardless of actual income, education or employment status.

Also more than half of participants said they determine people's trustworthiness by their smile. No wonder Hollywood ing?nue Hilary Duff got porcelain veneers to cover four chipped front teeth. She's not the only one, Michael Douglas, Jessica Simpson, Eva Longoria and yes, even Tom Cruise have gleaming smiles because of a teeth-whitening procedure or veneers.

Can you blame them? In studies, including one by the American Dental Association and Oral-B, nearly half of people surveyed said that the first thing they notice about people is their smile.

Having a healthy, attractive smile is important to almost everyone. Teeth and gums provide structure to the lower part of the face. Your mouth is the focus when we speak, eat, laugh and kiss. It makes sense that a healthy looking smile can affect overall confidence.
