Dental Teeth Whitening: A Complete Guide from Causes of Discoloration to Whitening Maintenance

Hello. This is Smile Studio Dental Clinic.

Teeth help us chew food and absorb nutrients, and they also play a role in producing clear pronunciation when we speak.

Straight, bright teeth are also important from an aesthetic standpoint and make up a large part of a first impression.

If your teeth become dark or yellow, you may worry, “What if people think I don’t brush my teeth?”

Today, for those who are concerned about yellow teeth, Smile Studio Dental Clinic would like to share information about the causes of yellowing teeth and teeth whitening to help improve them.

Why do teeth look yellow?

👉 If you are naturally yellow

Just as everyone has different facial features and body shapes, tooth color also varies from person to person.

If enamel is thin from birth and the dentin underneath is thick, teeth may look more yellow.

Enamel has a white tone, but the dentin beneath it is ivory or yellowish, so the thinner the enamel, the more noticeable the discoloration can be.

👉 If the color changes with age

"My teeth used to be white, but they seem to be getting duller and duller."

This phenomenon is a natural change that comes with aging.

This is called age-related tooth discoloration.

After baby teeth fall out and permanent teeth come in, enamel wears down over long periods of use, allowing the dentin to show through more and making teeth appear yellow.

👉 Eating foods that contain pigments

If the cause is not congenital factors or age-related change, your diet may be the reason.

Frequently consuming foods or drinks with strong pigments can cause staining as pigments build up on the tooth surface.

Typical examples include chocolate, wine, cola, green tea, coffee, and curry.

In particular, Americano, which many people drink often, can also be a cause of tooth discoloration.

If it is difficult to avoid these foods, be sure to brush your teeth after consuming them.

👉 Smoking

Nicotine and tar in cigarettes adhere to the tooth surface, darken the gums, and stain the teeth brown.​

The longer you smoke, the more severe the discoloration becomes. For your health, quitting smoking is the best option, isn’t it?

👉 Cavities and tartar

If you do not brush properly or oral hygiene is not managed well, cavities and tartar can develop.

Cavities and tartar make teeth look yellow.

To prevent these problems, proper brushing habits and regular dental checkups are essential.

Also, did you know that scaling is covered by insurance once a year!

For gum health and clean teeth, please remember to keep up with it.

Teeth whitening to make teeth look whiter

Teeth whitening can be done by visiting a dental clinic for treatment or by using at-home whitening products.

At the clinic, professional treatment is provided using whitening systems certified by the Ministry of Food and Drug Safety.

The treatment is carried out with medication and light therapy. Each session takes about 30 minutes, and after about three sessions, you can expect a noticeably brighter result.

At home, people mainly use products sold on the market.

These whitening products need to be used consistently over a long period of time to see results.

They may not be suitable for those who want to brighten their teeth in a short time.

How long do the effects of teeth whitening last?

The duration of whitening depends on each person’s care routine.

Whitening treatment applies a solution and then burns away the pigments that darken teeth to make them brighter. For this reason, it is important to pay attention to stain management.

After teeth whitening, avoiding foods with pigments and reducing smoking and caffeine intake are the keys to maintaining the results longer.

In general, it is recommended to maintain whitening every 4 to 6 months, and you should check your condition through regular dental visits.

Precautions after teeth whitening

After teeth whitening, teeth may temporarily become sensitive, and a cold sensation may occur.

In such cases, it is better to avoid foods that are too cold or too hot.

Also, white spots may temporarily appear on the teeth.

This is a phenomenon caused by differences in the density of the tooth structure, and it will gradually disappear over time, so there is no need to worry.

Today, we looked at the causes of tooth discoloration and how to manage it.

Teeth whitening is just the beginning; ongoing care is more important.

If visiting the dentist feels burdensome, why not get a light checkup at a nearby clinic?

For a healthy smile, start with small habits!
