The Difference Between At-Home Whitening and Dental Whitening

Teeth Whitening Effect

Nearby dental clinic for teeth whitening

No matter how striking your facial features are,

yellow teeth can dull the overall impression.

That is why many people have recently been looking for at-home teeth whitening products,

but many still wonder whether they really deliver clear results.

At-home teeth whitening and dental whitening,

what is the difference,

and why does Gangnam Saero Dental Clinic recommend dental whitening?

In this post, let’s look at the teeth whitening effect.

✿Check Point✿ Dental Whitening vs. At-Home Teeth Whitening

Advertisements commonly seen on social media and online shopping malls.

Phrases claiming that teeth will become pure white

after just one use are eye-catching,

but some may include lighting and retouching effects,

or may be false and exaggerated advertising.

Shall we compare them in more detail?

At-home teeth whitening:

All products sold online are quasi-drugs,

so the risk of side effects is low because the effects are also modest,

but as described, the teeth whitening effect may be minimal,

and there are cases where safety is difficult to verify.

There may also be products with false advertising or products not approved by the Ministry of Food and Drug Safety.

Dental whitening:

The whitening agents used in dental clinics are prescription drugs,

so because the effects are strong, they require a dentist’s supervision and prescription.

Under the Medical Service Act, false advertising is not possible,

which is also an advantage because the actual teeth whitening effect can be confirmed.

Prescription drugs:

Strong effect, but a doctor’s prescription and supervision are required.

Over-the-counter drugs:

Can be purchased at a pharmacy, with relatively mild effects and side effects.

Quasi-drugs:

Can be purchased online, with the mildest effects and side effects.

In other words, at-home teeth whitening is something you can try lightly,

but if you want a definite effect, dental whitening is recommended.

In a dental clinic, the treatment is not limited to simply applying the agent.

The patient’s oral condition is checked,

and the procedure is performed safely by adjusting the appropriate concentration and time.

In addition, the exact cause of yellowing teeth is identified,

and it is diagnosed whether whitening effect can be achieved with dental whitening alone,

while the solution is carefully controlled so that it does not flow onto the gums or other areas,

reducing the possibility of side effects.

Another advantage is the use of home-care whitening products in combination.

To help maintain the whitening effect received at the dental clinic for a long time,

a management program is provided together, which can improve sustainability.

✿Check Point✿ Dental Whitening Process

  1. Oral examination and checking the condition of the teeth
  2. Application of gum protection
  3. Application of professional whitening agent
  4. Activation using light (laser, LED, etc.)
  5. Aftercare and home-care guidance

Through this process, a noticeable teeth whitening effect

can be achieved in a short time.

✿Check Point✿ Side Effects of Dental Whitening

Because dental whitening is stronger than at-home teeth whitening,

the following side effects may occur.

Tooth sensitivity

Possible surface damage

Recurrence over time

To minimize these problems,

an experienced medical team should tailor the treatment according to the patient’s condition,

and for a certain period after the procedure,

it is advisable to avoid smoking and staining beverages (coffee, wine, etc.).

As mentioned earlier,

‘accurately identifying the cause of yellowing teeth,’

‘diagnosing whether whitening effect can be achieved with dental whitening alone,’

and ‘carefully adjusting the solution’

all mean that

the procedure requires the skilled technique of the medical staff in charge.

If you want to safely maintain the teeth whitening effect for a long time,
