Some people do not have enough space for their teeth to line up straight, others have too much space leaving unattractive gaps between teeth. Dental spacial problems can occur between any teeth in the mouth. It is most noticeable with it occurs in the upper front teeth, the central incisors.
Methods for treating spacing problems are dependent on a number of factors, including whether the teeth have a history of being heavily filled due to cavities over the years. The ideal situation for correcting gaps between teeth would be one where the teeth are basically straight, have a nice bright color, and have no existing restorations. When the space gape is 3mm or less the situation for correction is ideal. When teeth are too wide in proportion to their height, this creates a cosmetic dilemma.
Once it is ascertained that the teeth meet the ideal criteria for composite resin bonding the work can begin. The space between the teeth is noted, ideally, you would be dividing the space divided between the two teeth so that in the end the two treated teeth would look symmetrical. The type of resin material and the color would be chosen by the dentist and approved by the patient. To obtain a natural looking result it is important that the bonding material emerges from the tooth below the gum line. A natural looking result can only be achieved if the side of the tooth added to appears to grow out of the gum tissue.
To achieve this natural look, the cosmetic dentist typically places a small string between the surface to be bonded and the gums, this pushes the gum away from the tooth allowing the bonding material to be shaped not only on the side but on the front and back of that aspect of the tooth. The space is closed a tooth at a time. When one tooth side is completed, the cosmetic dentist shapes and polishes the bonding. The bonding is observed from both sides, front and back, and importantly looking down the tooth from its edge. The bonding must appear as an exact extension of the side of the tooth in order to not appear fake to the observer. Once one tooth’s side has been completed and polished, the process is begun anew for the side of the adjacent tooth which will be treated to close the other ½ of the space.
Achieving a natural, realistic looking space closure between teeth is one of the most challenging procedures a cosmetic dentist does. When correctly performed by the dentist and properly maintained by the patient the results can continue to look natural for many years in the future.
Dental bonding can be your most cost-effective solution in creating a beautiful smile.
