To answer this question, we really need to differentiate the two treatments as they are two different treatment entirely. 

Composite bonding is an additive process. In simple terms, we carefully sculpt composite resin over the teeth in question. This can be used to treat chipped, fractured, uneven and gappy teeth. Composite can also be used to replace old fillings on front ( or back) teeth. The great advantage of bonding includes:

1. Treatment is completed in one visit; an instant smile transformation!
2. Minimally invasive. There is little, if any, drilling of the underlying teeth needed.
3. Biologically safe for the teeth and gums. There is no risk of damage to the nerve.
4. Composite can be easily maintained.
5. More affordable than porcelain veneers or ceramic crowns.
6. Composite will protect the underlying teeth from further wear and tear.
 

At Progressive Dentistry in Fulham, we are huge advocates of minimally invasive dentistry and have been preaching this philosophy for many years. Early detection, prevention and intervention when needed, will have far better outcomes in the long term. In terms of dentistry, tooth decay is one of our most common diseases to treat. In the days of the past, teeth were heavily drilled with large cavities made so that amalgam (metal) fillings could be packed in. This would seem quite archaic now and thankfully, we have vastly superior solutions.
