Sometimes people hold back their smiles not because they do not want to smile, but their "not so beautiful" teeth make them do this. When your teeth are not beautiful, you are ashamed to smile at people. People may not realise that your teeth are not beautiful, but your awareness of how they look forces you to hold smiles back. According to you, your teeth are not white enough, they are not of the right shape, they do not sparkle and so on. This awareness affects your self-esteem and self-worth. All of these results into making you feel inferior to others.
The feeling of inferiority brought about by not so beautiful teeth can be eliminated by dental work by a qualified dentist. By "qualified", I do not mean any dentist, who has gone through the education system and acquired the title of a dentist. I mean a qualified "cosmetic" dentist. A cosmetic dentist is a qualified dentist, who combines dentistry expertise with aesthetics. An ordinary dentist only believes in removal and replacement of teeth. Plus, an ordinary dentist doesn't have the beauty aspect in mind when performing his dentistry works.
A cosmetic dentist is a specialist, who has aesthetics and artistic attributes in him. His main aim is to give you that smile that you have always wanted. Unlike an ordinary dentist, a cosmetic dentist does not aims at having a mouth full of teeth but aims at giving you smile made of sparkling white teeth. Cosmetic dentists are artistic in their work. They always work with the results they want to achieve in their mind. They work towards giving you that wonderful smile, a smile that is warm and inviting.
You can easily tell the difference between work of an ordinary dentist and that of a cosmetic dentist. The work of an ordinary dentist will have dull teeth. The shapes are not like those of natural human teeth. Having teeth that do not look like natural human teeth makes the patient's case worse. I would rather stay with my not-so-beautiful teeth than have white teeth that do not look natural. The dentistry work done by an ordinary doctor does not sparkle. For example, when there are spaces between the teeth, the spaces appear like dark triangles from a distance. To treat such a case, an ordinary dentist might just fill in the space to hide the gap, which might make it look unnatural. Whereas, dentistry work done by a cosmetic dentist will be more natural than natural human teeth-- it is translucent and sparkling.
When choosing on the dentist to work on your smile, start by learning if they are cosmetic dentists or not. You can simply tell this from pictures of previous dentistry works they have performed. You can also ask friends where they got their smiles done. A smile is something you will carry around wherever you go. For this reason, you need to settle for a dentist that will give you a dazzling smile. You need to realise that not every dentist has artistic and aesthetic attributes in him or her and therefore, not every dentist can give you that wonderful smile. If you doubt the capability of a doctor, try another one. Do not gamble with your smile.
