bleaching

Alsalmo alaykum,this is the second time I am sending you this question as I sent it about 1 week ago and so far I was not sent any reference number. I am a dentist and I am asked by patients to improve the appearance of their upper front teeth or gums. This may be because: 1. Their teeth are yellow or discolored and they want them whiter. 2. They have some teeth that have are small in size or disfigured or too long, or displaced, or rotated or there are spaces between their teeth and they want that corrected. 3. Too much of their gum shows when they smile and they want more tooth showing or their gums have dark racial dicouloration in form of areas that are dark brown and they want that removed.In general as a dentist for these problems the following could be done: 1. Bleaching teeth to make them look whiter but this has only a temporary affect and usually needs to be redone in the future. 2. Placing composite restorations, porcelain veneers or crowns depending on the problem the patient has whether it is to cover discoloured teeth, make teeth bigger and close spaces between teeth etc. Composites can be removed and redone as they may discolor or fracture due to the weakness of the material, where as porcelain veneers and crowns are more of a permanent solution as they are stronger. 3. For the gums showing too much on smiling, periodontal surgery could be done and the dark pigmentation of the gums could also be removed.Dentists are always taught to do what is ideal for the patient and a pleasant dental appearance is one of the aims of their work. Also lots of patients are very embarassed because of the appearance of their teeth and may withdraw from social events or not smile so much or hide their teeth as much as they can because of this and when their teeth are done they have more confidence and are much more happier.the aim for the dentists is to get the ideal color, shape, size and appearance for the patient's teeth so that everything looks natural and pleasant. Jazak Allah kul kair.
