What is Dental Bonding?
tooth bonding Candidates
Just about any adult with healthy teeth could benefit from bonding to cover imperfections. Bonding doesn’t solve underlying problems, but it is very versatile in masking cosmetic problems. Still, there are circumstances where a better solution could be a crown or maybe porcelain veneers. Dr. Roberts or Dr. Sirota will discuss your options with you.

Dental Bonding Material
The dental bonding material is made of a composite resin, or plastic, that hardens and fuses to the tooth when the dentist shines a special light on it. Once in place, the bonding material is shaped to correct the specific defect, colored to match the patient’s natural tooth and polished until it is smooth. It is designed to look like your own natural tooth.
The Dental Bonding Process
Applying bonding to a patient’s teeth requires a three-step process. The preparation for the bonding material, the bonding resin being placed and the material being sculpted to the tooth.
An etching solution is applied to the tooth or teeth to prepare them to receive the bonding material. This solution gently roughens the surface of the tooth for a stronger bond between the tooth and the plastic.
A thin layer of the bonding resin is placed on the surface of the tooth and is sealed in place using a special light. Several layers of resin may be added and hardened in turn. Each layer takes only a few minutes to harden.
The bonding material is sculpted to the desired shape and colored to match the shade of the natural teeth. Finally, the bonding material is polished until it is entirely smooth.
How Long Does Dental Bonding Last?
How long your bonding treatment lasts depends in part on you. If you practice good hygiene and don’t chew ice, your bonded teeth will continue to look great for up to a decade. The dental bonding procedure takes 1 to 2 hours, and its results may last for up to 10 years before any restoration is necessary.
How Do I Take Care of Bonded Teeth?
Your bonded teeth require only normal good home hygiene practices, brushing for two minutes twice a day and flossing once daily. While resin is non-porous and resistant to staining, it can stain over time. You also need to consider that whitening does not really work on bonded teeth, so if your other teeth are whitened they may not match your bonded teeth.
Alternatives to Tooth Bonding
The usual alternative is applying porcelain veneers. They accomplish the same thing as bonding — covering cosmetic flaws. Beyond that, if you only have a tooth or two that is receiving bonding, an alternative could be to crown that tooth, completely covering the tooth down to the gumline. Crowns wouldn’t probably be realistic on a number of different teeth, however.
Dental Bonding Vs. Veneers
Dental bonding is compared with porcelain veneers, as they both accomplish the same thing — masking cosmetic imperfections and giving you a beautiful smile.
While their end goal is the same, dental bonding and the application of porcelain veneers do it in different ways. Bonding uses a resin material that is sculpted on the teeth, cured, and then polished. Veneers are thin porcelain shells that are cemented onto the fronts of the teeth. To make room for the veneers, approximately 0.3 mm to 0.5 mm of the tooth enamel must be shaved off.
In use, porcelain veneers do not stain and are quite durable. The resin used in bonding is more resistant to staining than natural tooth enamel, but it can stain over time. Veneers last longer, but are more expensive than bonding. Also, bonding is usually done in a single appointment, while veneers require two appointments.
Once you have veneers on your teeth, you will always need to have either veneers or crowns. This is because a portion of the enamel is removed to make room for the veneer, and this is irreversible. Similarly, your teeth are etched to prepare them for bonding. And no one who has bonding is going to try and have it stripped off and go back to how his or her teeth were before. So, you’ll keep having teeth re-bonded as the years go by.
