Are you worried about yellowing teeth? Feeling reluctant to smile in public or gloomy about how you look in photos? Don’t worry. I’m Hiroshi Miyashita from Tokyo International Dental Clinic Roppongi. As a specialist who protects dental nerves, I provide truly safe whitening that does not damage teeth.

At our clinic we believe that dental beauty isn’t just about appearance — it’s most important that it’s achieved without harming the teeth themselves. Whitening is not merely “making teeth whiter”; it can boost confidence in your smile, improve your overall impression, and increase attention to self-care. Our priority is “whitening that does no harm to teeth,” and we offer safe, effective plans tailored to each patient’s condition.

Seven benefits you can gain from whitening

Whitening does more than just lighten your teeth — it can bring several positive effects to your life. From a professional perspective, here are seven benefits of whitening:

• Improved appearance: Clean, white teeth improve first impressions.
• Increased confidence: A natural smile leads to more expressive facial expressions.
• Better communication: A brighter impression can raise likability.
• Photo-ready: Look your best at weddings and events.
• More youthful look: The overall facial impression appears firmer and younger.
• Greater oral-care awareness: The desire to maintain whiteness encourages better dental health habits.
• Higher self-esteem: Resolving concerns about tooth color can make you feel better about yourself.

Tokyo International Dental Clinic Roppongi Whitening — Commitment to safety and effectiveness

Whitening is an effective aesthetic treatment, but depending on methods and agent use it can sometimes cause temporary sensitivity or put stress on tooth structure. As an endodontic specialist, my top priority is to avoid harming dental nerves and tooth structure. Features of our whitening approach include:

• Formulation that strengthens tooth structure: We use agents combining hydrogen peroxide with an apatite paste to promote remineralization during whitening, protecting tooth substance. This both strengthens the tooth surface and breaks down internal stains.
• Protocols to minimize damage: We tailor concentration, light exposure time, and number of sessions according to each patient’s sensitivity and medical/dental history (such as preexisting sensitivity, cavities, or condition of fillings).
• Sensitivity management: We provide fluoride treatments and dental pastes before and after procedures and use desensitizing agents as needed. We also explain in advance how we will handle any symptoms if they occur.
• Thorough informed consent: Before treatment we clearly explain expected results, risks, costs, and aftercare so that we can plan the treatment together with the patient.

Our whitening options

We offer three whitening plans to match your lifestyle and goals:

• In-office whitening: For those who want to see results quickly. This is performed under specialist supervision, offering safety and rapid effect.
• At-home whitening: For those who prefer to achieve a natural whiteness gradually. Using custom trays and low-concentration agents at home, this method gives natural, longer-lasting results.
• Dual whitening: For those who want both speed and longevity. Quick whitening is done in the office, with follow-up home treatment for maintenance.

Who this is recommended for

• People concerned about yellowing or staining of their teeth
• Those preparing for a wedding or important event
• People who often appear in public, such as for interviews or customer service roles
• Those who want to whiten without damaging their teeth (those who align with our clinic’s approach)

What you should know

Whitening is not equally effective for all types of discoloration. Intrinsic staining (for example from tetracycline) and some fillings or crowns may respond only partially. Temporary sensitivity can occur, but we manage it appropriately at our clinic. Long-term maintenance also depends on lifestyle factors — frequency of consuming strongly colored foods and beverages and smoking habits are important to review.

Message from the director

From my long experience caring for and protecting dental nerves, I believe “beauty” and “function/health” cannot be separated. What matters in whitening is not just changing appearance but the resulting smiles and daily confidence for our patients. If you are looking for safe whitening that does not harm your teeth, please consult with us. We will first examine your oral condition in detail and propose the best plan for you.

Consultation and appointments
