“Is bonding better than veneers?”

It depends. They are not exactly different approaches for the same dental problem. There are so many factors that have to be evaluated to make the correct decision that you should question your dentist about the pros and cons for your specific situation. Remember, bonding is usually done chairside in one visit and veneers usually require tooth preparation and are two visits incorporating the cost of the laboratory.

All depends what you are trying to accomplish. Veneers tend to last longer

It depends on the situation. Is this for front teeth? If so, veneers are better. If there is a lot of grinding or clenching going on, the patient should get a splint/bite guard made.

Better? I would say no. Easier to repair? Yes. As long lasting as veneers? No. Less expensive? Definitely.
I hope this helps.

Bonding costs less, but chips and discolors frequently. Veneers are stronger, last longer, and can look better longer.

Bonding and veneer have two separate functions and their composition is different. Bonding material is a resin. Molded and hardened in the mouth. Veneer material is porcelain. Lab made and baked in an oven. Porcelain is stronger and doesn’t stain. Bonding is good for smaller areas, and color matches better. Veneers are often done in a few teeth for cosmetic purposes. The answer to your question is, it depends. 

Complicated answer. Both have pros and cons. Bonding is used for minor modifications to teeth. It can be used to close spaces, fill cavities and alter the appearance of teeth. It can sometimes be reversible (you can remove it to restore spaces between). It is much cheaper to have done than veneers. It does not require lab work, so it can often be done in one visit. It is not as strong, long lasting or as beautiful, when completed, as porcelain laminates. They are a more conservative procedure, as not as much (if any) tooth preparation is required before bonding. Porcelain laminates are created by a laboratory from impressions made from your teeth. They typically need more than one visit to complete. They are never reversible. Once you have laminates, you will always need laminates (or crowns). You can never return to your natural teeth. When done properly, they are beautiful, lifelike and strong. They far outlast bonding. They are also much more expensive because they involve the use of a dental lab. They require more preparation (reduction) of your teeth than bonding because you need to have enough room on the face of your teeth to have the porcelain bonded. If the teeth are not sufficiently reduced, your laminates will be overly bulky. You may not be able to close your lips properly or speak properly. Your gums will become red and inflamed as you trap plaque and food debris at the margins of your veneers. Well done bonding can last from 4-8years. Well done veneers can last from 10-20 years before needing replacement. Depending on home & dental care and eating habits.
