Teeth Bleaching

Teeth is an important part of the human body. It is vital a part of our appearance and digestive system. The teeth is made up of dentine over which a layer of enamel a hard glossy substance protects the teeth.

The teeth over a period of time loose its sheen owing to many reasons such as lack of brushing, lack of hygiene, smoking and whole other features. Sometimes intake of antibiotics can also cause discoloration of the teeth. This discoloration of teeth results in the loss of the whiteness of the teeth over a period of time. This also leads to cavity formation.

Teeth BleachingSome times the discoloration of the the may be not form outside but from inside where the dentine gets discolored and this would require more than bleaching. The best way to remove discoloration is bleaching using peroxide solution where the dirt is removed while bleaching. For this solutions of hydrogen peroxide and carbamide peroxide are used.

carbamide peroxide breaks down releasing hydrogen peroxide an oxidizing agent thereby bleaching the dirt in the process. Concentration of hydrogen peroxide is recommended at .1% beyond which damage to teeth can occur. Solutions above this concentration can only be used under the supervision of a qualified dentist. Over bleaching can cause destruction to the enamel layer and further affecting the dentine layer.

Sometimes the discoloration is from within inside affecting the dentine and not the enamel in this case bleaching will not get back the shine veneers a cap or crown will have to be used to mask the discoloration. Bleaching can also be carried out using laser for which a paste containing hydrogen peroxide is applied and laser is shined on the specific part.

This procedure is accurate and the patient gets the benefit in one sitting compared to the normal method where the patient would have to sit for two or more sitting. Ultra  violet light is also used where a paste is applied and on shining ultra violet light high concentration of hydrogen peroxide is released cleaning the area. Most of the procedure can be done at home itself.

Regular mouth washes do contain bleaching agents which can be used periodically.  Only heavy stains and discoloration would require an expert dentist to bleach the area. Regular bleaching is also not advised owing to the damage it can cause. Prevention is the best method and adhering to proper oral hygiene is best advised.
