Dental bonding:

Dr. Manjula Alapati is known Frisco Cosmetic Dentist. Very experienced, Gentle primarily focussing on what is important for the patient. Dental bonding is carried out to fill gaps in the teeth and cover stains and chips. The process involves the application of a composite resin material to the tooth. The material, which is available in several shades, is sculpted to cover the desired area. It is then dried using a high-intensity light. The process does not cause any discomfort to the patient except when a minor tooth roughening is done. Dental bonding does not require more than one visit and is relatively inexpensive as compared to other dental restoration techniques.
