Tooth bonding is a dental procedure where a tooth-colored resin material (usually made of durable plastic) is applied onto the teeth and hardened using a special light. This ultimately bonds the material to the tooth, restoring and improving the smile. Tooth bonding can last for up to 10 years, with proper care and maintenance. Read on to learn more about this common dental procedure.

What is Tooth Bonding Used For?

• Alternative to amalgam fillings
• Change the teeth shape
• Close spaces in between teeth
• Improve the appearance of discolored teeth
• Make the teeth appear longer
• Protect a portion of the exposed tooth root when the gums recede
• Repair tooth decay
• Repair cracked or chipped teeth

How is Dental Bonding Done?

Before the dental bonding is done, a little advance preparation is necessary. Anesthesia is usually not needed unless the bonding used will fill a decayed tooth. In this case, the tooth will have to be drilled to change its shape. Anesthetics might also be necessary if the treatment area is near the nerve. The dentist ...

To start the bonding process, the surface of the tooth is roughened before applying a conditioning liquid. This will help the bonding material properly adhere to the tooth. The resin is then applied and molded before it is smoothened to the desired shape. A special light is used to harden the material. Once the material hardens, it is further trimmed, shaped and polished by the dentist to match the rest of the teeth. The whole process can take 30 to 60 minutes per tooth.

Advantages of Dental Bonding

Dental bonding is one of the easiest and cheapest cosmetic dental procedures. Unlike crowns and veneers which are custom made in labs, bonding mostly can be completed in one office visit unless many teeth are involved. Also, compared to crowns and veneers, only a small amount of tooth enamel is removed. It does not require any anesthesia until it is done to fill a cavity.

Disadvantages of Dental Bonding

The material used in dental bonding might be stain resistant, but it does not resist stains as well as crowns. Also, the bonding material is not as durable and long-lasting as other restorative procedures like fillings, veneers or crowns. The material can break or chip off the tooth. Because of this, some dentists recommend dental bonding merely for small cosmetic changes and corrections.

Dental Bonding Post-Procedure Care

Bonded teeth do not require any special care. You just need to follow basic good oral care habits, like brushing the teeth twice daily, flossing at least once daily, and rinsing with an antiseptic mouthwash at least once daily. It is also important that you see your dentist for regular check-ups and cleanings.

The bonding material can chip, so it is important to avoid habits like biting the fingernails, and chewing on ice, pens, and other hard objects. Also, never use your bonded teeth to open things. If you notice sharp edges on your bonded tooth, or it feels odd when you bite down on it, call your dentist immediately.

Lifespan of Dental Bonding

The lifespan of the material used in dental bonding will largely depend on how much bonding was done, including your oral habits. Usually, bonding material can last anywhere from three years to 10 years before it will require replacement or touch ups. If you are considering getting dental bonding, consult a reputable dentist in your area where you can talk about your smile goals, and if this procedure is the best option for you.
