Dental Bonding and Its Kinds

There are many factors that affect teeth that need to be improved with dental bonding. The natural color of the teeth can be affected or discolored by chips and cracks. Small repairs can be affected by composite adhesive resins. Bonding improves the overall appearance of the teeth to enhance the smile.

The causes of discoloration are:

  1. Tobacco is one of the main causes of tooth discoloration.
  2. Tea, coffee, and red wine can also contribute to tooth discoloration.
  3. Pigmented foods like cherries and blueberries also discolor teeth.
  4. Plaque hardens as a result of tartar buildup and appears yellow to brown.
  5. Age contributes to the yellowing or aging of the teeth.

Your dentist will first thoroughly clean your teeth and remove as much discoloration as possible. The dentist will then use composite resins or composite porcelain veneers to cover the surface of the stained teeth. It can also give broken or misshapen teeth an attractive, even appearance.

Composite Syndicate:

The surface of the tooth is first slightly reduced so that the new tooth is not too bulky. Using a mild acid, the surface of the tooth will be etched with microscopic grooves. A composite resin suitable for your existing teeth will then be applied to the surface of the tooth. It will be shaped and then fixed with a curing light. To complete the process, it will be polished and smoothed.

Sheet adhesion:

Veneer bonding is a completely different process. After reducing the front of the tooth, the dentist will take an impression of the tooth and match the color to your existing teeth. The impression will be sent to the dental lab where a porcelain veneer will be created to match the color and shape of your existing teeth. Once returned from the lab, the veneer will be bonded to your teeth with dental adhesive cement. The advantages of a porcelain veneer are that it provides better color matching and lasts five to ten years.

Dental bonding is considered when:

  • The teeth are decayed. Composite resins are used to fill cavities.
  • Repair of chipped or cracked teeth
  • The spaces between the teeth are closed to improve the appearance.
  • The general appearance of discolored teeth should be improved.
  • The shape of the tooth needs to be changed
  • As an alternative to fillings
  • Teeth should appear longer

Types of aesthetic dental bonding

Direct bonding:

With direct bonding, the veneers use bonded composite materials. Direct veneers may not involve the removal of large amounts of dental material. If the dental material is not expelled, these veneers are said to be a reversible application.

Indirect bonding (traditional veneers): Indirect veneers use a ceramic material, such as porcelain. The main exterior of the tooth is shaped to provide space for the veneer material. Therefore, indirect veneers are not a reversible treatment.

Composite veneers

There are direct and indirect composite resin veneers. Indirect composite veneers are created in a dental lab from an impression of your teeth. A small amount of tooth structure must be removed for this indirect composite restoration.

A direct composite bonding technique does not require as much removal of tooth structure. Hardened teeth for composite bonding are decoupled, pumice waxed and acid etched. A dental teeth bonding agent and optional opacification can be added before the composite is cast on the outside of the tooth. This process can correct the appearance and body of the teeth.

Traditional porcelain veneers

A porcelain veneer is ideal for old teeth. Creating a porcelain veneer uses an indirect technique and involves developing the tooth by removing a thin layer of tooth structure, making a remnant, and sending the remnant to the laboratory for construction of the porcelain veneer. A temporary veneer is shaped and worn until the second visit. At the next visit, the temporary veneer is ejected and the permanent veneer is placed and bonded to the outside of the teeth with composite.

Porcelain veneers can be colossal and if done incorrectly they can stain the margins and flake off. They are expensive but have good aesthetic properties and are more permanent than composite veneers.


LUMINEERS are ultra-thin (approximately 0.2mm) highly translucent dental adhesive veneers made of porcelain, allowing them to replicate the natural appearance of tooth color. Although traditional veneers are slightly thicker and require polishing of the original tooth enamel, little or no tooth reduction is required for LUMINEERS bonding due to its thin state. LUMINEERS bond to normal teeth in the same way as composite veneers, so they do not require anesthesia like traditional porcelain veneers.
