Whitening

The outer layer of the tooth is called enamel. The natural color of the tooth is produced by the absorption and diffusion of light through the enamel, combined with the color of the underlying dentin layer. The thickness and smoothness of the enamel are genetically determined. If the enamel is thinner, the color of the dentin has a greater influence on the overall color of the tooth. Every day, a thin layer called the pellicle forms on the enamel. This thin layer, along with the pores in the enamel, retains various stains.

Natural color

The outer layer of the tooth is called enamel. The natural color of the tooth is produced by the absorption and diffusion of light by the enamel, together with the color of the underlying tooth layer, dentin.

Smoothness

The thickness and smoothness of the enamel are genetically determined. If the enamel is thinner, the color of the dentin plays a greater role in determining the overall color of the tooth.

Removal of Stains

Every day, a thin layer called the pellicle forms on the enamel. This thin layer, together with the pores in the enamel, retains various stains.

Problem treatment

Whitening can be of several types – in-office whitening or at-home, external and internal. The active agent in whitening gels is carbamide or hydrogen peroxide. They remove stains from the enamel pores.

Possible solutions

Sometimes changes in tooth color are the result of taking certain medications or genetic disorders affecting the tooth structure, and cannot be resolved by whitening alone. In such cases, veneers — or in some situations, crowns — are a long-term solution.

At-home whitening

The dentist determines the initial shade of your teeth and then takes an impression of your upper and lower dental arches. Our dental technicians create a clear tray molded to fit your teeth. The patient receives this tray along with a whitening agent. This agent has a lower concentration of carbamide/hydrogen peroxide. The whitening gel is applied inside the tray, which is then worn for a specified period. Maximum effect is typically achieved within 2-3 weeks. Some tooth sensitivity may occur; if the whitening agent use is stopped, the sensitivity usually disappears within 1-2 days. The procedure can be repeated after a few months.

In-office whitening

A stronger whitening agent is applied to the teeth after the gums are initially protected with a gingival barrier. The whitening gel is activated by light. The procedure can be repeated several times until the desired effect is achieved.

Internal whitening

Internal whitening is performed again in the dental office, on teeth with treated root canals. Some old root canal filling materials can cause discoloration of the tooth. Internal whitening restores the tooth’s original color.
