2. Understanding In-Office Teeth Bleaching
What Is In-Office Teeth Bleaching?
In-office bleaching is a professional dental procedure where a high-concentration bleaching gel (usually 25%-40% hydrogen peroxide) is applied to the teeth and activated using a special light (LED or laser). Unlike at-home kits, this method delivers noticeable results in just 60-90 minutes.
How Does It Work?
The bleaching agent penetrates the enamel and breaks down stain molecules through an oxidation process. The light source accelerates the reaction, enhancing whitening efficiency.
Benefits Over At-Home Bleaching
- Faster results (3-8 shades lighter in one session)
- Stronger, professionally applied formulas
- Reduced risk of gum irritation (due to precise application)
- Customized treatment based on tooth discoloration causes
3. Dental Codes for In-Office Bleaching
Dental procedures are categorized using Current Dental Terminology (CDT) codes for insurance and billing purposes. Below are the most relevant codes for in-office bleaching:
| CDT Code | Description | Notes |
|---|---|---|
| D1999 | Unspecified whitening procedure (custom) | Used when no other code fits |
| D9972 | External bleaching for non-vital teeth | For internally stained teeth |
| D9973 | External bleaching for vital teeth (in-office) | Most common for cosmetic whitening |
Insurance Coverage: Most dental plans consider whitening a cosmetic procedure and do not cover it. However, some flexible spending accounts (FSAs) may allow reimbursement.
