TEETH WHITENING

## Teeth Whitening

TEETH WHITENING

## What is *teeth whitening?*

A treatment in which a whitening agent breaks down the staining accumulated on and within the tooth surface, producing a shade lighter than the original. **We check the condition of the gums and teeth before proceeding.**

1. **Surface staining**Food, drinks and smoking stain the tooth surface.
2. **Internal change**The dentine colour deepens with age.
3. **Breaking down pigments**A peroxide-based whitening agent breaks down the pigments. It lightens the colour alone, without trimming or covering the tooth.

Tooth colour darkens through a combination of surface staining and internal change.

COMPARE

### In-office whitening and at-home whitening

MEGAPLANT Dental Clinic Seodaemun plans the two methods **either on their own or in combination**, according to the cause of the staining and the condition of the teeth.

At-home whitening

- WhereWorn at home over a set period
- ConcentrationLower concentration
- MethodWhitening agent placed in a custom-fitted tray
- CharacterTakes longer but lightens gradually

In-office whitening

- WhereAt the clinic
- ConcentrationComparatively higher concentration
- MethodGums protected, then the agent is applied and managed
- CharacterThe clinical team monitors it and can address sensitivity or gum irritation immediately

※ At-home whitening is also used to maintain results after in-office whitening.

CHECK

### What we check before the procedure

The same effect does not appear with every type of discolouration. **Staining from coffee, tea and tobacco** tends to respond comparatively well.

We check first

- Whether there is decay, a cracked tooth or an exposed tooth root
- Whether there is gum inflammation or tartar (if so, treatment and scaling come first)
- Whether there is resin or a crown on the front teeth (restorations do not whiten)
- Whether you usually experience marked sensitivity

When whitening alone may not be enough

- **After root canal treatment**A single tooth has darkened following root canal treatment
- **Drug-induced or congenital**There is banded discolouration from medication or congenital causes

※ The response to whitening may be limited here, so we also review covering the colour with aesthetic resin or a no-prep veneer. Identifying the cause first is the way to reduce unnecessary procedures.

PROCESS

### Treatment process

1

Examination and shade record

We record the current tooth shade and confirm whether whitening is possible.

2

Gum protection

A protective barrier is applied so the whitening agent does not contact the gums.

3

Application of the whitening agent

The whitening agent is applied to the tooth surface and left to act for a set time.

4

Review and maintenance guidance

We check the change in shade and, if needed, plan additional sessions or at-home whitening.

CARE

### Sensitivity and precautions

Points to know before and after the procedure

- **Temporary sensitivity** may occur during or immediately after whitening. In most cases it subsides over time, and if it is marked we adjust the concentration and duration of the whitening agent.
- For a few days after the procedure, it is advisable to avoid **strongly coloured foods** such as coffee, tea, wine and kimchi stew, **as well as smoking.**
- The whitening effect **is not permanent** and may gradually revert depending on dietary habits, so maintenance care is required.
- If you are **pregnant or breastfeeding**, or have a dental or gum condition, we adjust the timing of the procedure.
