Hello, this is Lucid Dental Clinic.

To create a bright, radiant smile, simply lifting the corners of your mouth is not enough.

Depending on the condition of your teeth as they naturally show, your impression can also change significantly. In particular, yellowed teeth are often difficult to improve even with diligent brushing, which can be a concern.

That is why more and more people are now looking to complete a cleaner, more vibrant smile through professional teeth whitening.

Today, we will tell you more about the teeth whitening treatment offered at Lucid Dental Clinic.

What Is Teeth Whitening?

Teeth whitening is a procedure that removes staining substances from the surface of the teeth or chemically breaks down pigments deposited inside the teeth, making the teeth brighter than before.

Rather than simply cleaning away surface residue, it improves the tooth color itself using professional whitening agents, so the results differ from whitening toothpaste used at home.

At Lucid Dental Clinic, we perform whitening after a precise diagnosis of the patient’s dental condition, using agents that do not damage the teeth.

In addition to a natural tone-up effect, we also combine various care methods to minimize discomfort such as sensitivity or irritation.

Because the structure and color of teeth differ from person to person, the results of the same whitening treatment can vary.

At Lucid Dental Clinic, we take these differences into account, design a customized whitening plan, and also provide ongoing care guidance after the procedure.

What Causes Tooth Staining?

There are many reasons why tooth color changes. Common causes include food, beverages, and smoking habits.

▪ Drinks with strong pigments such as coffee, black tea, and cola Even one or two cups a day can cause staining on the surface of the teeth.

▪ Dark-colored foods such as kimchi and curry Common Korean dishes that we often eat in daily life can also contain pigments that affect the teeth.

▪ Smoking Nicotine and tar from cigarettes build up on the teeth and cause a yellowish color.

▪ Incomplete brushing habits Even if you brush two to three times a day, staining can build up easily if you do not clean properly between the teeth.

▪ Aging As we age, the enamel on the teeth gradually becomes thinner, and the yellowish dentin underneath becomes more visible, which can make the teeth look yellow.

Because it is difficult to maintain the bright, natural color of the teeth due to these various causes, many people regain a brighter smile through professional whitening treatment.

Teeth Whitening Is Recommended for These People. Lucid Dental Clinic’s teeth whitening is not only for cosmetic purposes, but also brings great satisfaction to those who want to improve their overall image and regain confidence.

▪ People with important events such as weddings, interviews, or photo shoots ▪ People concerned about yellow teeth caused by smoking ▪ People who frequently consume drinks that cause staining, such as coffee and wine ▪ People who want to make their overall impression look brighter ▪ People who want a shade brighter than their natural tooth color

If you have been uncomfortable because of the color of your teeth, teeth whitening can bring a positive change.

How Is Teeth Whitening Performed at Lucid Dental Clinic?

Teeth whitening is performed by applying whitening agent to the surface of the teeth and then activating it with LED light.

At Lucid Dental Clinic, we accurately diagnose the patient’s dental condition, create a customized whitening plan, and proceed safely.

  1. Pre-treatment diagnosis Before whitening, we check the current condition of the teeth and the degree of staining. If there is tooth decay or gum disease, treatment may take priority over whitening.

  2. Scaling We remove surface tartar and plaque to help the whitening agent work evenly.

  3. Whitening agent application We evenly apply a dedicated whitening agent to the surface of the teeth.

  4. Light exposure We use a special LED light to activate the whitening effect.

  5. Post-treatment check We check whether the desired brightness has been achieved and also provide guidance on aftercare.

Because each person’s tooth color and structure are different, some people see enough results with one session, while others may need additional whitening.

Please Note These Points After Teeth Whitening. Teeth whitening is a safe procedure, but following post-treatment precautions is important for maintaining the results.

▪ To keep your teeth white, avoid staining foods. For 24 to 48 hours after the procedure, it is best to avoid foods that cause staining. Coffee, chocolate, curry, wine, and kimchi should be avoided right after whitening.

▪ Please avoid smoking as much as possible. Nicotine and tar can easily redeposit on the teeth after whitening.

▪ Tooth sensitivity is temporary. You may feel sensitivity for about a day after whitening, but it usually goes away naturally. If symptoms continue, you should visit the clinic for evaluation.

▪ Brush with a soft toothbrush For teeth and gums that are more sensitive after the procedure, it is best to use a soft toothbrush.

▪ Maintain the effect with regular care. If needed, you may combine home whitening products, or consider additional whitening after 6 months to 1 year.

Lucid Dental Clinic’s whitening is different. At Lucid Dental Clinic, we go beyond a simple teeth whitening procedure and provide customized care that takes into account the patient’s lifestyle habits and dental health condition.

We place importance not only on whitening results but also on safety, use only verified whitening agents, and provide thorough consultation and guidance before and after the procedure.
