Gangnam Teeth Whitening: A Clear and Radiant
Choice for Regaining Your First Impression
| Summary |
|---|
| 1. Tooth discoloration can interfere with a neat and bright impression, creating high demand for whitening procedures that improve it safely. |
| 2. Teeth whitening is a treatment in which a professional prescription whitening agent is applied to discolored tooth surfaces and special light is used to clearly break down staining substances. |
| 3. The patient’s existing tooth color shade is precisely measured to determine the most natural and harmonious brightness before proceeding. |
| 4. Temporary sensitivity may occur after the procedure but soon improves. Limiting foods that cause staining, such as curry and coffee, helps maintain a bright smile for longer. |

Hello,
This is Newen Dental Clinic.
Tooth staining can sometimes cause a person to take a more passive attitude in business settings where first impressions are important, such as job interviews or important meetings.

For those who feel upset whenever they look in the mirror because of yellowed teeth, or who want to regain a clear and bright smile in a short period and feel more confident, professional whitening is an excellent cosmetic oral solution.
Characteristics of Professional Whitening

This procedure combines a formally approved, high-concentration professional prescription whitening agent with specialized light and laser equipment that activates the whitening ingredients, bringing about a change within a short time.
Under the thorough control of dental professionals, the procedure is carried out precisely after measures are taken to protect delicate gum tissue, providing a high level of safety. Usually, during one visit, the laser is applied continuously for approximately 15–20 minutes, allowing patients to notice a brighter tooth tone immediately after the procedure.
It can provide a high level of satisfaction for those who need a rapid change to a clean image before an important wedding, photo shoot, job interview, or similar event.
Step-by-Step Procedure

If visible tartar, sticky plaque, or thick external contaminants caused by cigarette tar have accumulated on the tooth surfaces, the whitening agent may not be absorbed evenly into the teeth, which can result in uneven whitening.
To prevent this in advance, detailed scaling is performed to make the surfaces smooth and clean, creating a clean base on which the agent can react evenly.
Application of Gum Protector

A special protective gel is carefully and thoroughly applied without gaps along the line where the teeth and gums meet. It is then hardened using a light-curing unit to fully protect the gum tissue from the whitening agent.
Once all preparations are complete, the whitening agent is delicately applied to the front surfaces of the teeth in an even layer. Specialized light and laser equipment that maximizes the active effects of the whitening ingredients is then applied evenly for approximately 15 minutes.
Depending on the patient’s tooth sensitivity and desired level of brightness, this process is usually repeated two to three times, with a fresh application of the agent each time.
Removal of Residue and Final Check

Once all laser exposure is complete, the guide gel protecting the gums and the whitening agent on the tooth surfaces are thoroughly washed away with warm water.
After rinsing the mouth clean with a mouthwash, the changed final result is checked by honestly comparing it with the tooth shade guide measured at the beginning, and the procedure is completed.

Q. Temporary Symptoms After the Procedure
A. Immediately after dental teeth whitening, the teeth may temporarily become somewhat sensitive. You may briefly feel a sharp or tingling sensation when drinking cold water or when air comes into contact with the teeth.
This is an entirely natural and normal phenomenon that occurs because, as the whitening ingredients penetrate deeply into the teeth and take effect, the tiny channels that transmit stimulation to the nerves inside the teeth—the dentinal tubules—remain temporarily open and can therefore detect changes in temperature more easily.

Q. Post-Procedure Care
A. For at least one week after the procedure, special care and attention should be given to dietary habits in order to maintain the whitening effect fully.
Foods containing strong artificial or natural coloring should be strictly avoided. If you inevitably eat such foods in the course of your social life, immediately rinse your mouth several times with clean water and brush your teeth promptly before the coloring agents can penetrate the teeth.
The tar in cigarettes can also quickly stain whitened teeth yellow. Therefore, maintaining smoking cessation during the treatment period and immediately afterward is an important way to preserve bright and translucent-looking teeth for longer.
